Eunorau Defender-S 2.0 Review Canada (2026): Two 750 W Hubs, Full Suspension, 83 km at 20 km/h, $3,799

The Defender-S 2.0 in Dry Grass Camo. The bike is Eunorau's own photograph, locked pixel for pixel; the studio plate around it is ours. The 83 km is the range section's figure for 20 km/h on both motors with an 80 kg rider on level pavement.

Eunorau Canada published the Defender-S 2.0, also sold as the Hunter X6, on 23 September 2026 and opened pre-orders at $3,799. It replaces the original Defender-S in Eunorau's Canadian catalogue, and the first reviews a search returns are of that older bike. This review is of the 2.0 alone: every specification is Eunorau Canada's, read on 7 October 2026, every store term is Zeus's, read the same day, and every range and fit figure is computed from those published numbers and printed with its conditions.

Who the Defender-S 2.0 is for

On 23 September 2026 Eunorau Canada replaced the original Defender-S with the Defender-S 2.0 and opened pre-orders at $3,799 with no ship date. The decision is $3,799 for a bike no Canadian owner has ridden yet, whose two 750 W motors put it outside every province's e-bike definition.

This review works the decision out from the published figures: how far it goes at your speed and temperature, which frame fits your inseam, and what each province calls it.

The Defender-S 2.0 is for you if your riding leaves the pavement and keeps going: two-track to a stand, a gravel concession road, sand, snow or a rutted trail. Eunorau's record opens with the words built for challenging terrain and all-season exploration, and its page's headline is Go Where One Motor Stops.

If you have read about the first Defender-S, its numbers do not carry over. For the 2.0 Eunorau prints 40.50 kg (89.3 lb), a 136 kg (300 lb) maximum payload, 203 mm rotors front and rear, a 48 V 17 Ah pack and a Class 2 start at 32 km/h. Every figure on this page is the 2.0's, read on 7 October 2026.

Riding mostly pavement and want two motors for less? The FAT-AWD 3.0 puts two 500 W hubs on a step-through from $2,299. Want full suspension with a 500 W motor you can check against your province's rule? The Eunorau Defender is that bike, and our review of it is the sibling to this one.

What it is. A four-bar full-suspension fat-tire frame with a 750 W hub in each wheel, a bottom-bracket torque sensor, an RST GUIDE 75 mm fork with lockout, an AOS01 air shock, Shimano CUES 1×9 gearing, 203 mm hydraulic rotors and a MINI TOUCH colour display with Bluetooth, in Dry Grass Camo, Moon Black or Army Green and a 17-inch or 19-inch frame.

The legal line. Each motor is 750 W. Every provincial e-bike definition stops at 500 W, three of them counting the motors together in so many words, so this is an off-road machine in every province; the law section quotes each one.

Eunorau Canada's specification, with the geometry

Eunorau Canada prints the Defender-S 2.0's specification in two places, the page's spec panel and the product record behind it, and on 7 October 2026 the two agreed on every figure below. The table is Eunorau's; the watt-hours are our arithmetic, 48 volts times 17 ampere-hours.

Read from Eunorau Canada's Defender-S 2.0 page and product record on 7 October 2026. A throttle is not listed on either; see the conflicts table.

Eunorau's Dimensions and Rider Fit table, both frames:

Eunorau's rows as printed on 7 October 2026. Row J runs from the crank axle to the saddle top (the fit section explains how it was placed).

Two 750 W hubs and a torque sensor

A 48 V 750 W hub motor turns each wheel, and one 48V 25A dual-motor controller runs the pair; Eunorau rates them at 1,500 W combined and prints one torque figure, 85 N·m maximum.

Both wheels turn at the same speed, so each motor carries half the load, and that is where a second motor earns its place: when the rear tire spins on snow, sand or wet grass, the front one is still pulling.

When you pedal, a bottom-bracket torque sensor reads your effort. Eunorau's Canadian page says the assist answers how hard you press rather than crank movement alone: lighter pressure brings gentler support, and harder pedalling more. On a slippery climb that is the difference between feeding power in and spinning a tire.

Ask Eunorau whether you can ride on one motor and its page answers that the dual-motor control system is designed to manage motor operation for different conditions, then sends you to the supplied manual for the final production control labels and operating sequence. The original Defender-S had a three-position switch; whether the 2.0 keeps one is not published, so every range figure here models both motors driving.

What the second hub buys you, in the saved model: up an 8% grade the pair holds 29.6 km/h with 80 kg aboard and 28.3 km/h with the full 136 kg, and up a 12% grade 28.5 and 22.5 km/h (the climb table). Both brake levers carry motor cut-off sensors, so either lever stops the drive.

The four-bar suspension

Both ends of the Defender-S 2.0 move: an RST GUIDE fork with 75 mm of travel, preload adjustment and a lockout up front, and an AOS01 air shock, 165 mm eye-to-eye, working a four-bar rear linkage.

Eunorau's page says the linkage, fork and shock help isolate impacts and keep the wheels tracking across broken ground, which is what two driven wheels need, since a wheel in the air drives nothing.

The fork locks out for a long climb on a graded road, and the shock is adjustable: an air shock is set by its pressure, so set it for your weight with gear before the first ride off the pavement. Seventy-five millimetres is short travel for a full-suspension bike; it takes the edge off roots, frozen ruts and washboard rather than drops. The Specter-S 4.0 carries a 140 mm fork if travel is the thing you ride for.

The fat tires do part of the same work. At low pressure a 26 × 4.0 tire flattens over roots and gravel, and Eunorau's own advice for this bike is to adjust speed and tire pressure for the conditions.

Nine gears, 203 mm brakes, the display

You shift nine speeds on Shimano's CUES group: an SL-U4000-9R RAPIDFIRE PLUS shifter, an RD-U3020-SGS rear derailleur and a CS-LG300-9 cassette, 11 to 36 teeth, driven by a 42-tooth chainring on 170 mm cranks.

On a hub-drive bike the gears set your cadence and leave the motors' load alone, and the gear section prints what your legs are worth in watt-hours.

Hydraulic discs stop both wheels on 203 mm rotors, up from 180 mm on the original Defender-S, and Eunorau's record says the integrated motor cut-off sensors immediately interrupt motor assistance when either brake lever is engaged. On a 40.5 kg bike coming down a loose grade with 136 kg aboard, rotor size is the spec to read before torque.

The rest, as Eunorau lists it: a MINI TOUCH colour display with Bluetooth for pedal-assist and speed settings; a 700 mm riser bar with 25 mm of rise on an adjustable alloy stem, with 130 mm lock-on grips; an LED headlight with an electronic horn; 26-inch double-wall rims laced with 12-gauge, 36-hole spokes; an adjustable aluminum kickstand and 9/16-inch folding pedals. At the back there is a red reflector and no light, so add a rear light before you ride the approach in the dark.

Two frame sizes and the second battery

The same bike comes in a 17-inch and a 19-inch frame at the same $3,799. Eunorau's table separates them by 51 mm of seat tube, a saddle range 50 mm higher, 10 mm of reach and 3 mm of stack, and the wheelbase grows from 1,306 to 1,316 mm.

Eunorau prints a rider window of 160 to 193 cm for the 17-inch and leaves the 19-inch blank; the fit section works out where each frame fits from the saddle figures instead.

At 40.50 kg it is a two-person lift onto a truck bed, so plan on a ramp or a hitch rack rated for the weight, and it runs 2,042 mm long on the 17-inch frame. Take the battery out before you lift: Eunorau lists the pack as removable.

A second pack nearly doubles the energy. Eunorau's page prints up to 128 km combined with an optional second battery without naming its capacity, and its Canadian battery listing for the Defender S sells a 48 V 15 Ah pack at $679 and a 17 Ah pack at $809, both on Samsung cells. Zeus sells the universal 48 V 15 Ah secondary battery at $679, and the range tables model that 15 Ah pack, 1,536 Wh in all.

The frame you pick decides how the second pack rides. The universal pack's listing names DEFENDER-S 19" plainly and DEFENDER-S 17" with the note lock out rear shock to use. Those listings print DEFENDER-S without a version number, so if you plan to carry two packs often, that line is a reason to choose the 19-inch frame, and to ask us to confirm the fit on the 2.0 before you order the pack.

The Defender-S 2.0 against three Eunorau siblings at Zeus

Three Eunorau bikes at Zeus answer the same buyer with a different trade: the FAT-AWD 3.0 keeps two motors and drops the rear shock and $1,500; the Defender keeps full suspension with one 500 W motor you can check against your province's rule; the Specter-S 4.0 trades the second motor for a mid-drive and 140 mm of fork.

Each row is the maker's own figure, read at Eunorau Canada on 7 October 2026; Zeus prices are from our listings the same day.

Maker figures from each bike's Eunorau Canada page (Defender-S 2.0, FAT-AWD 3.0, Defender, Specter-S 4.0), read 7 October 2026; Zeus prices the same day. Kilogram and km/h conversions are ours. The Specter-S 4.0's description says 330 lb where its spec table says 300 lb.

Pick the Defender-S 2.0 when rough ground calls for a rear shock as well as two driven wheels. Pick the FAT-AWD 3.0 to save $1,500, carry 170 kg and step through the frame. Pick the Defender for a lighter full-suspension bike whose single 500 W motor and 32 km/h setting you can hold against your province's rule. Pick the Specter-S 4.0 when you climb more than you plough: a mid-drive through 11 gears with 140 mm of fork, and a rack and fenders in the box. Our Eunorau collection holds all four.

How far the Defender-S 2.0 goes on one charge, computed

On the 816 Wh pack, both hubs on the throttle and an 80 kg rider aboard, the Defender-S 2.0 covers about 83 km at a steady 20 km/h over level pavement, about 69 km at 25 km/h and about 53 km at its 32 km/h start setting.

Keep the 15% Eunorau's FAQ says to leave in the pack and those plan as 71, 59 and 45 km. Add the optional 15 Ah second pack and a 20 km/h day plans at 133 km.

Behind every table in this section is one saved model of this bike, built on the figures Eunorau prints: a 48 V 750 W hub in each wheel, 85 N·m, the 48 V 17 Ah pack, 40.50 kg, 26 × 4.0 tires and the 32 km/h start. The formula lists every input and its source. Your ride, in three reads:

1. Pick your pace in the speed table. 20 km/h is a relaxed trail or concession-road cruise; 32 km/h is the setting's ceiling on the flat.
2. Correct it for your load and your ground with the weight rows, which run from 45 kg to the 136 kg rating, and the hill tables, which run from 2% to 15%.
3. Plan from the 15%-kept column, because Eunorau's battery advice is to recharge with 10 to 15% left.

How far does it go at my speed?

Pace decides more than anything else you control: 107 km at 12 km/h shrinks to 53 km at 32 km/h on the same charge. The air's drag grows with the square of speed, so the power it takes grows with the cube (Martin et al., 1998), and riding at 32 km/h where 25 would do gives up 16 km of the 69.

Both hubs on the throttle, an 80 kg rider with gear, level pavement and still air at 25 °C. The 15%-kept column leaves the upper end of Eunorau's 10 to 15% advice in the pack; the last column adds the 15 Ah second pack for 1,536 Wh.

Pedalling stretches it furthest. The hubs drive the wheels whether you pedal or not, so every watt your legs add is a watt the pack keeps:

Both hubs and the 816 Wh pack, an 80 kg rider on level ground. Easy pedalling is 75 W at the cranks, steady is 150 W; legs alone means your watts hold that pace with the motors idle.

To hold 20 km/h the wheels need 134.2 W (the road-power equation). Give 75 W of it yourself and the hubs cover the gap on 5.7 Wh a kilometre, which carries you 143 km; give 150 W and you hold the pace with the hubs idle. On legs alone the same equation moves you and the 40.5 kg bike at about 14.3 km/h on 75 W and 20.9 km/h on 150 W.

Which gear saves battery?

None of them directly: the nine gears set how fast your legs turn, and the motors sit in the wheel hubs and never see the gears. What saves the pack is the effort you put in. At 20 km/h on the flat it cuts the cost from 9.8 Wh a kilometre to 5.7, and at 20 km/h up a 4% grade from 25.8 to 21.1.

Watt-hours drawn from the 816 Wh pack for each kilometre, both hubs, an 80 kg rider, still air. At 150 W you carry the flat at 20 km/h yourself and the motors draw nothing.

Drop to an easier gear before a climb so your cadence stays smooth while the bike slows. The 42-tooth chainring and Shimano's 11–36T CUES cassette give you a low gear to push in while the hubs do the heavy part.

What do hills cost, and how steep a hill can it hold?

Every 100 m you climb on the throttle at 16 km/h costs about 40 Wh on a 4% grade and about 46 Wh on a 10% grade, beyond what the same distance would cost flat. Lifting an 80 kg rider and the 40.5 kg bike through 100 m takes about 33 Wh at the wheels; the hubs and the pack lose the rest to heat.

Both hubs, the 816 Wh pack, an 80 kg rider holding 16 km/h up each grade in still air.

The fastest pace each grade allows on the throttle:

Both hubs on the throttle in still air, the 40.5 kg bike plus the load named in each column, each hub held to 85 N·m. Each cell is the top steady speed the modelled pair can hold on that grade.

This is where two driven wheels earn their place: up a 12% grade the pair holds 28.5 km/h with 80 kg aboard and 22.5 km/h with the full 136 kg. On loose ground the front hub pulls while the rear pushes, which is the traction on loose, soft, or uneven surfaces Eunorau's page describes. Read Eunorau's 85 N·m as the pair's total instead of each motor's and one cell changes: 136 kg up 12% is no longer held on the throttle alone (limitations).

Does my weight change the range?

It does, and most on climbs: at 20 km/h on the flat, 80 kg of rider and gear gets 83 km and the full 136 kg gets 70 km. Up an 8% grade at 16 km/h the gap opens wider, 26 km for a 45 kg load against 12 km for 136 kg.

Rider and gear on the 40.5 kg bike, both hubs, the 816 Wh pack, still air. The 136 kg row is Eunorau's maximum payload.

Does cold weather drain the battery?

Yes: the 83 km ride at 20 km/h shrinks to about 67 km at 0 °C, 61 km at −10 °C and 49 km at −20 °C. At freezing the cells give back about 89% of their 25 °C energy, the air is denser and the tires roll harder (Rothhämel, 2023); at −20 °C the cells are down to about 67%.

20 km/h on the throttle with both hubs, 80 kg aboard, level pavement, the 816 Wh pack. The central figures use McMaster University's measured LG HG2 cell held at the air's temperature; at 0, −10 and −20 °C the bracket spans the other published cell data (limitations).

Eunorau names snow among the Defender-S 2.0's ground, beside pavement, gravel, sand and uneven trails, so for a January ride read your kilometres from the −10 and −20 °C rows, and keep the pack indoors between rides (our winter e-bike guide).

Do the tires cut range?

Less than your speed does: across the fat tires Bicycle Rolling Resistance measured, the 20 km/h ride runs from 77 to 96 km, 83 at the median. Eunorau prints the size, 26 × 4.0-inch fat tires, and no tread or casing name, so the model takes the median of the ten 26 × 4.00 tires on the lab's drum, with the fastest and slowest as the bracket.

Level pavement, 80 kg aboard on the throttle with both hubs, the 816 Wh pack. The lab rolled each tire at 12 psi under 42.5 kg at 29 km/h; the coefficient converts its watts.

Eunorau's 64 and 128 km, as rides

Eunorau prints up to 40 miles / 64 km on the standard pack and up to 80 mi / 128 km combined with the optional second battery. In this model an 80 kg rider on level ground in still air covers 64 km at a steady 27.2 km/h on the throttle, or 32.0 km/h pedalling easily alongside. With the 15 Ah second pack, Eunorau's 128 km comes at 25.6 km/h on the throttle or 30.9 km/h with easy pedalling. Eunorau's FAQ adds that actual range varies with rider weight, terrain, speed, assist level, temperature, tire pressure, and riding style.

How the range tables are computed

Each row begins with the power the wheels need at one steady speed, from the road-power equation Martin and colleagues checked against riders on real roads in 1998:

Wheel power = v × [ m × g × (Crr × cos θ + sin θ) + ½ × ρ × CdA × v² ]

In it, v is speed; m is the rider, gear and bike together; g is gravity; θ is the grade's angle; Crr is rolling resistance, where 0.0105 means a drag equal to 1.05% of the weight on the tires; ρ is the air's density; and CdA is the drag area of rider and bike. From the wheels back to the cells, four steps:

1. Your pedalling reaches the rear wheel through the chain at 97.7% (Martin et al., 1998); the two hubs supply the rest.
2. Each hub follows the curve of a hub motor whose figures are published, Bafang's RM G0H0: 510 rpm unloaded, 426 rpm at its rated point, at least 80% efficient, here wound for 48 V and 750 W. The two share the torque equally. Their unloaded speed is fitted at 33.6 km/h, so that the pair carries an 80 kg rider on the throttle to Eunorau's 32 km/h and no faster, and each is capped at 85 N·m.
3. The pack turns some energy to heat on its own: on a 48 V pack Arango, Lopez and Ceren measured it, 3.1% at 20 km/h on the throttle here.
4. Watt-hours per kilometre are the cells' watts divided by the speed, and kilometres are the 816 Wh, less any cold loss, divided by the watt-hours per kilometre.

Every input and its source. A number with no row here does not enter the model.

One ride worked through, wheel to cells: 80 kg aboard, both hubs on the throttle at 20 km/h, level pavement. Rider and bike weigh 120.5 kg. The tires take 69.2 W and the air 65.0 W, so the wheels need 134.2 W, and a 762 mm wheel turns 139.2 times a minute. Each modelled hub (1.960 N·m per amp, 0.405 Ω and 0.83 A unloaded, from Bafang's published figures wound for 48 V and 750 W) carries half the load; together they turn out 9.2 N·m on 6.3 A, 71% efficient at so light a load.

The hubs draw 189.5 W between them, and with the pack's own losses the cells give up 195.6 W, 9.78 Wh a kilometre. So 816 ÷ 9.78 comes to 83.4 km, or 70.9 km with 15% kept.

Martin and colleagues' Appendix I (90 kg on a 0.3% grade at 8.36 m/s), the RM G0H0's rated point in Bafang's workbook, and the two-hub arithmetic in the model's own selftest, run 7 October 2026.

What the 136 kg payload covers

Eunorau rates the Defender-S 2.0 for a maximum payload of 300 lb / 136 kg, including rider and cargo. You and everything you carry on the bike count against the 136 kg; the bike's own 40.5 kg does not.

Picture a 90 kg rider with a 10 kg pack and the 4.5 kg second battery, about 105 kg, well inside the rating: at 20 km/h the weight table brackets that load between its 100 kg row, 78 km per pack, and its 120 kg row, 74 km, and the pair still climbs a 12% grade at 24.3 km/h with 120 kg aboard.

Weigh what you carry before the first trip out, and keep you, your pack, a rifle or bow case and any bolted-on gear inside 136 kg. For loads that belong behind the bike, Eunorau's Canadian listings name the Defender-S among the bikes its trailers hitch to: Zeus stocks the two-wheel hunting trailer with a Defender-S hitch option (100 kg maximum load, $530 to $600) and the cargo trailer (45 kg, $530 to $600).

The FAT-HS/Defender-S/FAT-AWD 2.0 rack and fender set is $189 at Zeus and adds a place to strap gear; each of those listings prints DEFENDER-S without a version number, so ask us to confirm the fit on the 2.0 before you order one. Hunters: our hunting e-bike guide covers the gear, and the legal-access atlas covers where a 1,500 W machine may ride on public land.

Will the Defender-S 2.0 fit you? Computed from your height

Choose the frame by your height: the 17-inch saddle range reaches the fit formula's height for most riders up to about 170 cm (73 of 100 there), and the 19-inch for most from 175 cm to 180 cm (91 and 59 of 100); at 185 cm the 19-inch reaches 16 of 100 at 109% and 47 at 106%.

Below about 165 cm, the 17-inch frame's top tube is the number to check: 48 of 100 riders at 160 cm clear it standing in bare feet.

In the rows where each frame fits, you lean about 24 to 27 degrees toward the grips, and with your back relaxed your hands carry about a fifth of your weight. Each figure comes from the 6,068 bodies in the US Army's anthropometric survey, with the saddle at 109% of inseam from the pedal axle, on the 17-inch frame as Eunorau photographed it and the 19-inch from Eunorau's printed differences. Three steps to your size:

1. Measure your inseam in bare feet. Stand against a wall, draw a hardcover book up firmly between your legs where a saddle would sit, and measure from the floor to the book's top edge.
2. Find your height in both saddle tables and confirm your inseam falls inside that row's range; a longer inseam behaves like the row above.
3. Order the frame whose row reads higher for you, then set the saddle on arrival with the knee and heel checks at the end of this section.

Eunorau prints a window of 160 to 193 cm for the 17-inch and leaves the 19-inch blank. Its frame-size page puts a 17-inch frame where its 158–168 cm row (15"–17") meets its 168–178 cm row (17"–19"), and a 19-inch where that row meets the 178–185 cm row (19"–21"). The tables below sit closer to the size page: from about 175 cm up, most riders' saddle height runs past the 17-inch frame's top setting.

How high should the saddle go?

Set the saddle 109% of your inseam above the pedal axle; on the 17-inch frame Eunorau's seat range covers that for 100 of 100 riders at 160 cm, 73 at 170 cm and 2 at 180 cm. Published practice runs from 106% to 110.4% of inseam (Ferrer-Roca et al., 2012), and 109% is the figure Peveler and colleagues checked against knee angle in trained cyclists.

Eunorau prints the range as J: Seat height 585–735 mm on the 17-inch and 635–785 mm on the 19-inch, measured from the crank axle to the saddle top; its photograph of the 17-inch frame shows the saddle 633 mm from the crank axle, inside that range. With the saddle top taken as the point on the seat post's fitted axis, leaning back 73.1 degrees, that sits J from a crank axle 34.1 cm off the ground, the 17-inch saddle runs 91 to 105 cm off the ground and the 19-inch 96 to 110 cm.

Ground-to-saddle height the 109% formula gives the median rider at each height, and how many riders of 100 at that height can set it inside the 17-inch frame's 91 to 105 cm, at 109% and at 106%. Each row is the survey's one-inch band nearest that height; women and men pooled.

The same rows on the 19-inch frame's 96 to 110 cm: Eunorau's 635–785 mm placed along the same post as the 17-inch's.

At 180 cm the 17-inch saddle stops a median of about 4.5 cm short for the riders whose formula height it misses, and at 185 cm about 7.8 cm, which is why the 19-inch takes over there. On the 19-inch the shortfall at 190 cm is about 5.7 cm; if you are 190 cm or taller, the seat post's length is the question to settle with us before you order.

Can I put a foot down at a stop?

On the 17-inch frame, standing astride at a stop, 10 of 100 riders at 155 cm clear the top tube in bare feet, 48 at 160 cm and 85 at 165 cm. Eunorau prints no standover, so the top tube's upper edge is read on its photograph, 5 cm ahead of the saddle's nose, at 76.5 cm.

Riders of 100 at each height whose bare-foot inseam clears the 17-inch frame's top tube at 76.5 cm. Shoes add some height; if you do not clear it, you lean the bike to one side to put a foot down.

The 19-inch frame's top tube stands higher by an amount Eunorau does not print, so read this table as the 17-inch's alone. Under about 165 cm, the 17-inch is the frame to ask us about, and the FAT-AWD 3.0 puts two hubs on a step-through you never swing a leg over.

Will I feel cramped, or stretched out?

Expect a sporty lean: on the 17-inch frame the median rider tips 24 degrees from vertical at 155 cm and 24 at 175 cm to reach the grips. On Eunorau's photograph the grips sit 52–56 cm ahead of the crank axle and 76–81 cm above it, and the 19-inch adds Eunorau's extra 10 mm of reach and 3 mm of stack.

Lean from vertical for the median rider on the 17-inch frame as photographed: the smallest trunk angle at which a straight arm reaches the grips from where the sit bones rest, across the saddle's sit zone and the grip's extent.

On the 19-inch frame the saddle rides higher for the same rider, so the lean grows a little: the median rider leans 27 degrees at 180 cm against 23 on the 17-inch. Eunorau lists an adjustable alloy stem, which brings the grips up toward you if you want to sit taller.

How much weight goes on my hands?

With your back relaxed, the median rider's hands carry about 18 to 19% of body weight on the 17-inch frame from 155 to 175 cm, and 19 to 21% on the 19-inch from 165 to 185 cm. For scale, ten road racers riding on the hoods put 15% of their weight on the stem (Carahalios, 2015).

The share of body weight your hands carry with a relaxed back on the 17-inch frame, from each body's segment weights (Clauser et al., 1969); the span covers the sit zone and the grip's extent, and the weight column is the survey median for that height.

A trunk you hold up yourself takes part of that load, so read each row as the ceiling. Raising the adjustable stem lowers it, and on long days padded gloves help: across 36 experienced cyclists they cut pressure over the ulnar nerve by 10 to 28% (Slane et al., 2011).

How do I set the saddle when it arrives?

Aim for your knee bent 25 to 35 degrees with the pedal at the bottom of its stroke (Peveler et al., 2007). The heel check gets you there fastest: heel on the low pedal, raise the saddle until that leg just goes straight. In 19 trained cyclists it put 70% inside the knee range, more than either inseam formula (Peveler et al., 2005). Hold the bike upright, open the post's clamp, set the height by the heel check, and close the clamp firmly before you ride.

How the fit tables are computed

Three rules make every fit row: the saddle sits 1.09 inseams above the pedal axle, the lean is the least trunk angle that lets a straight arm meet the grip, and the hand load is the share of upper-body weight that lean puts on the bars.

A worked case: you are 173 cm tall with an 82.9 cm inseam, the survey's median at that height. Your saddle goes 90.4 cm from the pedal axle, 73.4 cm from the crank axle once the 170 mm crank comes off (LeMond's 88.3% of inseam gives 73.2).

Set on the post's fitted axis 73.4 cm from a crank axle 34.1 cm off the ground, with the post leaning back 73.1 degrees, that saddle top stands 105.0 cm up, just inside the 17-inch frame's 105 cm top.

Every fit input and its source.

The photograph is Eunorau's Moon Black from the drive side, the first image in its gallery, with both tires fitting circles of nearly the same size on a level line. Before a single point was read, its scale (7.96 pixels per centimetre, from the 17-inch frame's 1,306 mm wheelbase) was checked against Eunorau's table:

The total length, chain stay, seat tube and effective top tube land within 3.5%; the bracket, stack, reach and head tube read 4.8 to 6.8% off, and Eunorau's own drawing disagrees with its table on those too. Over all 6,068 bodies, LeMond's route plus a 170 mm crank works out to 109.0% of inseam from the pedal, beside the 109.2 ± 0.9% measured in trained cyclists (Peveler et al., 2005).

Seven Canadian riders, one bike

The same machine read against seven rider situations we hear on the phone; each verdict is a number read from the fit model, the range model or the law table for that rider.

Figures from the fit model, the range model and the law section; the 16-year-old's row comes from the law table.

What the law calls it, province by province

Canada has had no federal e-bike definition since the federal power-assisted-bicycle definition was repealed effective February 4, 2021 (SOR/2020-22), so the rules are provincial, and every province's definition stops at 500 W.

Each of the Defender-S 2.0's two hub motors is 750 W, so on 7 October 2026 it sat outside the e-bike definition of all 13 jurisdictions, whether a province counts one motor or both.

Three definitions count the motors together in so many words: British Columbia's one or more attached electric motors that have a continuous power output rating that, in total, does not exceed 500 W; Prince Edward Island's continuous power output ratings that in total do not exceed 500 watts; and Yukon's 500 W or less in total for the motor or combination of motors. The others write a single motor of 500 W, and a 750 W hub is not a 500 W motor. Three provinces, Ontario, Alberta and Saskatchewan, still define the e-bike by pointing at the repealed federal text, and the table says so in each of those rows.

Each row's operative words are quoted from the statute, regulation or regulator page linked in it, read from our saved copies on 7 October 2026 (each copy fetched between 19 September and 7 October 2026); our province guides carry the age, helmet and passenger rules the row leaves out. This table is a reading of the definitions, not legal advice.

The 45 km/h setting

Eunorau's highlights call the bike Class 2 Speed limited Unlockable, and its record lists a Power-On Setting of Manufacturer-defined Class 2 mode, up to 20 mph / 32 km/h, and a Manufacturer-Defined Class 4 Setting of up to 28 mph / approximately 45 km/h. The product FAQ closes its speed answer with follow local regulations.

Class 1, 2 and 3 are labels from US state law and Class 4 is Eunorau's own; no Canadian statute uses any of them.

The setting changes nothing in the law table, because the motors already decide it: at 32 km/h or at 45 km/h, each hub is 750 W. What the 45 km/h setting does change is your stopping distance and your range: every range figure on this page is at the 32 km/h start setting, and our wattage guide works through how many watts a rider needs and what each province allows.

Charging and battery care

Eunorau ships a 54.6 V 2 A charger and prints approximately 6–8 hours for a full charge. A typical outing asks far less: 20 km at 20 km/h on both motors draws about 196 Wh from the cells, a quarter of the pack.

Eunorau's FAQ says batteries typically last 5-6 years and will still deliver more than 80% of their original capacity after 500 charge cycles; that charging batteries when they still have 10-15% of power remaining will significantly extend their lifetime; and that a pack stored for more than 2 weeks should be kept in a cool, dry place with a 70%-80% charge remaining in it. In a Canadian winter that means the pack comes inside with you, and our battery guide covers the rest.

Where Eunorau prints a figure two ways

Eunorau describes the Defender-S 2.0 on its Canadian product page, in the product record behind it, on a lettered geometry drawing and in its accessory listings. Where two of them part ways, the right-hand column names the figure this review uses; neither version is called wrong.

The page and record were read 7 October 2026, the warranty, FAQ, frame-size and battery pages and the US page the same day.

Recall record

On 7 October 2026 no Health Canada recall or safety alert and no US Consumer Product Safety Commission recall named Eunorau, the Defender-S or the Hunter X6. Health Canada's recalls and safety alerts search returned no results for Eunorau and for Defender-S; its 27 results for Defender were Land Rover and Bombardier vehicle recalls, a door-knob recall and a hand sanitizer, and its 19 results for Hunter X6 were croquet sets, heaters, window sheers and hunting scents. A control search for electric bicycle returned 1,479 results the same minute, so the instrument was reading.

The CPSC's recall database returned no recall for Eunorau in its title, description and product-name fields, each proved live by a control query that returned the Rad Power Bikes RadWagon 4 recall. A model name can appear in a recall under a seller's name rather than the maker's, so both searches are a floor, re-run at every republish.

Is it UL certified?

Eunorau Canada's highlights show UL CERTIFIED: Yes, and name no standard. Two standards stand behind a mark like that: UL 2849 for an e-bike's whole electrical system and UL 2271 for the battery pack alone, and which one, or both, the Defender-S 2.0 holds is not printed.

If your landlord, building or insurer wants the certificate itself, say so with your order and we will request it from Eunorau; our battery guide explains why the certificate's number matters more than the word.

Warranty, Zeus Care and who handles a claim

Read on 7 October 2026, Eunorau's Canadian warranty policy sets a term for each part: frame 10-Year, battery 24-Month, motor 24-Month, electrical components 24-Month. The policy is offered by Eunorau Bikes, a Nevada corporation, for bikes bought in the U.S. or Canada on or after August 1st, 2023, with a Canadian address in Markham, Ontario.

It asks for product registration right after the purchase, an e-bike check-up by a Eunorau specialist or dealer after the first year of use, and that you are the original purchaser; its frame warranty excludes any suspension parts, and the 24-month warranty does not include usual wear and tear and labor cost.

Buy the Defender-S 2.0 from Zeus and your first month of Zeus Care is included: we diagnose the problem, document it, present the claim to Eunorau and follow it up until there is a decision. Zeus Care plans continue that service for 1, 2, 3 or 5 years at $119, $229, $339 and $599; they are a service, not a warranty, and they add no parts coverage. Eunorau decides each claim under its own terms. Our Eunorau brand profile sets these terms beside the brand's record.

Buying it from Zeus

Each row read on 7 October 2026.

The value case in numbers. Our listing on 7 October 2026 split the $3,799 into 12 monthly payments of $342.89 at 15% APR, $315.68 in interest and $4,114.68 in all, or 3 payments of $1,298.12 at the same APR, $3,894.36 in all.

The listing's own note: rates range from 0-32% APR (subject to provincial regulatory limits), and payment options through Shop Pay Installments are subject to an eligibility check and approval. Our financing guide works seven financing options through with the real interest.

Change your mind after delivery and our refund policy applies: unused and unopened items within 15 days of delivery, with a 15% restocking fee and return shipping paid by you. A factory-defective bike is a different case, covered by the policy's dead-on-arrival rule: within the first two weeks of delivery and under 10 km.

The honest ledger

Green flags

• A 750 W hub in each wheel: up a 12% grade the pair holds 28.5 km/h with 80 kg aboard and 22.5 km/h with 136 kg (the climb table).
• Full suspension: a 75 mm RST GUIDE fork with preload and lockout and a 165 mm air shock on a four-bar rear (the suspension section).
• An 816 Wh pack, with a compatible 15 Ah second pack sold: about 83 km at 20 km/h on one pack for an 80 kg rider, and 133 km planned on two (the range tables).
• Nine Shimano CUES gears, 11 to 36 teeth, so your legs have a gear on any climb (the parts section).
• 203 mm hydraulic rotors at both ends, each lever cutting the motors.
• Two frames at one price: the 17-inch for riders to about 170 cm and the 19-inch from 175 cm in the fit tables (the fit section).
• Eunorau's own $3,799 on 7 October 2026, in every colour and frame, with a full refund if you cancel before it ships.

Red flags: where it is the wrong bike, and what to do

• You need an e-bike for roads, bike lanes or multi-use paths: each 750 W motor is outside every provincial definition. The Eunorau Defender is full suspension with a 500 W motor and a 32 km/h setting, and our 500 W collection holds the rest; check your province's row first.
• You ride mostly pavement and want two motors for less: the FAT-AWD 3.0 puts two 500 W hubs on a step-through from $2,299, with a 170 kg payload.
• You are under about 165 cm and need a low frame to stand over: the FAT-AWD 3.0 is a step-through with two hubs, or check your row in the standover table and call us.
• You and your gear total more than 136 kg: that is Eunorau's rating, and our heavy-rider guide lists the bikes rated above it; call us before ordering this one.
• You are 190 cm or taller: the 19-inch saddle reaches 0 of 100 riders at 109%, so email us your inseam before ordering.
• You need the bike on a fixed date: Eunorau has published no ship date; the FAT-AWD 3.0 and the Defender are current listings.
• You climb more than you plough: the Specter-S 4.0 is a mid-drive through 11 gears with 140 mm of fork, and our mid-drive versus hub guide explains the trade.

Who should buy it

Before you buy: the checklist

Eight checks: four that settle the bike and the frame, four for the order and the first week.

1. Read your province's row in the law table and decide where you will ride a 1,500 W machine; the atlas lists the trail systems and parks with a published answer.
2. Measure your bare-foot inseam and find your row in both saddle tables: 17-inch to about 170 cm, 19-inch from about 175 cm.
3. Total your weight, your gear and any second pack against the 136 kg; the bike's 40.5 kg is not part of it.
4. Measure where you will park it for a bike of 40.5 kg and 2,042 mm, and plan a ramp for any steps.
5. Work out your longest ride at 20 km/h on both motors: one pack plans 71 km for an 80 kg rider on the flat, two plan 133.
6. If you will run two packs on the 17-inch frame, read the pack listing's line on locking out the rear shock first, and ask us to confirm it applies to the 2.0.
7. Give the pack a full charge before the first ride: Eunorau lists 6 to 8 hours on its 54.6 V 2 A charger, and register the bike with Eunorau right after the purchase, which its warranty asks for.
8. Look the box over while the carrier is still there, and send us photos within 48 hours of any damage you find.

Limitations of this review

Twenty limits on this review, numbered and tied to the section each one qualifies.

1. The specifications are Eunorau Canada's, from its page, record, geometry table, battery and accessory listings, FAQ and warranty policy, recomputed wherever arithmetic enters. The range and fit models, the law table, the recall reads and our store terms are ours, each explained below.
2. Zeus sells this bike. The ledger routes each rider it suits less well to another bike we sell, and the law table is each statute's own line.
3. Every range row is one steady speed on one grade in still air. Stops, starts, headwinds and soft ground cost more; a tailwind costs less.
4. Eunorau prints the speed, the seat-height datum, the rider height, the fork adjustment, the stem, the second battery and the warranty more than one way (the conflicts table); the review uses the figure named there.
5. The law table reads the motor-power limb of each definition, with the speed limb where it decides, as our saved statute texts and regulator pages stood when read on 7 October 2026; the copies were fetched between 19 September and 7 October 2026. It leaves age, helmet and passenger rules to the province guides and is not legal advice.
6. Three provinces define the e-bike by pointing at the repealed federal text (Ontario, Alberta and Saskatchewan); the table reads each at its own words and names the pointer. New Brunswick's Act has no e-bike definition, so its registrar's page is quoted instead.
7. Québec's regulator answers on two pages: its e-bike page sets the 500 W and 32 km/h rule for public roadways, and its FAQ on non-compliant vehicles calls a 1,000-watt bicycle a bicycle rather than a moped and bars it from public roads and bike paths; both are quoted, and they agree on the road.
8. The recall reads ran on 7 October 2026: Health Canada's site search for four strings with a control, and the CPSC's three brand fields with a control. A name search is a floor.
9. Our price, orderability and Shop Pay terms come from our own listing, read 7 October 2026; the payments are its plan table for $3,799 at 15% APR, and the plan a buyer is offered depends on the eligibility check.
10. The motor model rests on a comparable hub's published curve, Bafang's RM G0H0, one per wheel, wound for 48 V and 750 W, with the unloaded speed fitted so two hubs carry an 80 kg rider to Eunorau's 32 km/h and no faster. Eunorau does not name the 2.0's hubs or say whether they are geared; its archived July 2025 page for the original Defender-S named Bafang 750 W hubs.
11. Eunorau prints one torque figure, 85 N·m, without saying whether it is each hub's or the pair's. The model caps each hub at 85 N·m. Read as the pair's, 42.5 N·m a hub, one cell changes: 136 kg up a 12% grade is no longer held on the throttle alone, and every other range figure stays the same. Eunorau's archived 2025 page for the original printed 80 N·m for each motor, which is the reading the model keeps for the 2.0's single figure, without proof that Eunorau means it that way.
12. The model splits the torque equally and does not model the 48V 25A controller's current limit; if the controller caps current below what two hubs draw on a steep climb, the climb speeds run lower.
13. No drum or road figure for the Defender-S 2.0's tire was found, so the model uses the median of ten 26 × 4.00 fat tires on Bicycle Rolling Resistance's drum, bracketed by the slowest and fastest of the ten.
14. The cold rows use McMaster's measured LG HG2 cell as the central line, bracketed by Samsung's 35E data sheet and Casado et al., 2025; Eunorau names 21700 cells in the record and Samsung cells in the battery listings, without a model number.
15. The two-pack column uses the 15 Ah pack Eunorau's Canadian listings sell for the Defender S and leaves out the pack's 4.5 kg; Eunorau's 128 km line names no capacity, and a 17 Ah pack is also listed.
16. No ride of the Defender-S 2.0 to empty, with its speed and load stated, was found in print, so the chain from wheel to pack is checked link by link against its sources, with no whole-ride figure to test it against.
17. The fit tables use the bodies of US Army personnel, 6,068 soldiers aged 17 to 58 measured in 2010 to 2012, each height row being the survey's one-inch band nearest the printed centimetres; the way inseam varies at a given height should carry over to Canadian riders, while the exact spread may not.
18. The 17-inch frame is Eunorau's photograph, held to its table on four dimensions; the 19-inch is that frame with Eunorau's printed differences (J 50 mm longer, reach 10 mm and stack 3 mm more), with the same post angle, cockpit and saddle. Its standover is not printed and is not given here.
19. The grip is read on the photograph at the adjustable stem's photographed setting, and the sit bones are placed in the saddle's rear-middle quarter; raising or lowering the stem moves the lean and the hand load, and the hand figure is a ceiling for a relaxed back. Treat the saddle formula as a first setting: in 19 trained cyclists the inseam formulas put 55 to 65% inside the 25 to 35 degree knee range (Peveler et al., 2005).
20. Expiry. Re-verify if Eunorau changes a motor, the pack, the speed settings, the payload, the rider window, the geometry or the second pack's listing, if our price or terms move, or if any province's definition changes.

The bottom line

The Eunorau Defender-S 2.0 is a $3,799 full-suspension fat-tire bike with a 750 W hub in each wheel, a torque sensor, nine gears, 203 mm hydraulic brakes and an 816 Wh pack, rated to 136 kg, in a 17-inch or 19-inch frame, and on 7 October 2026 it sat outside the e-bike definition of every province and territory because each motor is 750 W.

On both motors an 80 kg rider covers about 83 km at 20 km/h, 53 km at 32 km/h and 70 km at 20 km/h with the full payload, and the pair holds 28.5 km/h up a 12% grade. Buy it for loose ground, snow, trails and climbs on land where a 1,500 W machine may go; take the 17-inch to about 170 cm and the 19-inch from 175 cm.

The low-pressure route is open: call 1-866-938-7580 and a real person will confirm the frame and the ETA; cancel before it ships for a full refund; after delivery, unused and unopened bikes return within 15 days under our refund policy (15% restocking fee); and the financing guide works the monthly cost through before you decide.
