Freesky Alaska Pro M-520 Review Canada (2026): 2,160 Wh, Range Computed, Fit Measured

Zeus with the Freesky Alaska Pro M-520 on a ranch two-track in the Alberta foothills: a Playcut.ai rendering made from Freesky's own photograph of the Alaska Pro M-520.

By Milad Ghobadibeygvand, BScN (Western University, 2014) · Freesky's Canadian and US pages, product records, both manuals and both certificates, every provincial and territorial rule, and the Health Canada and US CPSC recall records read on 2 November 2026

The Alaska Pro is Freesky's one-motor, two-battery M-520: a full-suspension fat-tire bike with a 4,500 W peak rear hub motor, an 18 Ah and a 27 Ah pack (2,160 Wh together) and a 400 lb load rating. Every Freesky figure below was read on 2 November 2026 from Freesky's pages, its product records, its manuals and the two certificates its page links; the range and fit figures are computed, with the method linked.

Who is the Freesky Alaska Pro for?

The manual Freesky now links for the Alaska Pro, a file dated 19 October 2026, allows riding and storage down to −20 °C, where the one RedTail read in September stopped at 0 °C. Buy this 40.8 kg bike on Freesky's spec sheet alone and a rider over 5′8″ can end up with a saddle that will not go high enough, on a machine no province treats as an e-bike. Below we work out its range, fit and legal ground for Canada.

Its strengths are distance and carrying. Two packs hold 2,160 Wh, either one runs the bike, and Freesky rates it for 400 lb (181 kg) of rider and gear. That suits acreage, a hunting lease, a farm or a cottage road that is private.

It is the wrong bike for a commute, a bike lane or a third-floor walk-up. If your riding is on roads and paths, our guide to 500 W, 750 W and 1,000 W e-bikes shows where the provincial lines fall, and our long-range e-bike guide sets the Alaska Pro beside other long-range bikes.

What does Freesky print for the Alaska Pro?

Freesky's Canadian page prints one 4,500 W peak rear hub motor with 170 N·m, a 48 V 45 Ah battery in two packs (18 Ah and 27 Ah), 40 MPH, a 400 lb load and 90 lb of bike. The table quotes Freesky's wording, read on 2 November 2026, with metric conversions in the last column.

Freesky's figures have moved

Freesky's own documents print four peak figures for this bike, and they rise over time. By the dates RedTail gives them, a September 2025 post says "Official 2500W peak motor" with "a 48V 41Ah dual-battery system (1968Wh)"; a November 2025 holiday guide, "Peak 3000W brushless, 160Nm torque"; a May 2026 tire guide, "a powerful 4000W peak motor and 160Nm torque"; and the product page today, 4,500 W and 170 N·m.

Freesky's battery FAQ explains the packs: "Depending on production batch and configuration", they are 18 Ah + 23 Ah (41 Ah) or 18 Ah + 27 Ah (45 Ah). The labels on your own packs and frame settle which build you have, and older reviews, including the ride video further down, show earlier builds.

What Freesky does not print, and where its documents disagree

Freesky prints no rated (continuous) motor power for the Alaska Pro, no motor maker and no cell maker: not on its Canadian or US page, its product records, the text inside the 138 images on those pages or its manual, all read on 2 November 2026. The "4500W" is a peak. Its documents also disagree on several figures, and we print each side rather than pick one.

Read 2 November 2026. Plan on the certificates' lower water figures (keep the packs out of standing water; the manual excludes "water damage (including rust)" from the warranty), the higher weight when you lift it, and the drawing's figures when you check your inseam.

How far does the Alaska Pro go on one charge?

In our model, a 90 kg rider on the throttle gets about 139 km at 32 km/h and 185 km at 25 km/h from both packs (2,160 Wh), on flat pavement at 25 °C. Keep a fifth in reserve and plan on 111 and 148 km.

Freesky's "98-175 Miles" (158 to 282 km) asks for slow riding in the same model. The low end needs a steady 28 km/h on the throttle; the high end needs 13 km/h on the throttle, or 25 km/h with a steady 75 W from your legs.

The model is the one RedTail eBikes built for this bike, imported unchanged, and it reproduced all 21 figures RedTail publishes before we ran it in kilometres. RedTail's method section sets out the physics: Martin and colleagues' validated cycling model, fat-tire rolling resistance measured on a drum, measured rider drag, a comparable 1,000 W hub motor's published curve and LG cell energy by temperature.

Modelled: steady speed on flat pavement, 90 kg rider and gear, 25 °C, no wind, both packs full (2,160 Wh). A steady 75 W is easy pedalling. In the model the comparable 1,000 W motor holds up to 47 km/h on the flat with this rider; Freesky prints 64 km/h.

One input is a figure Freesky prints two ways. Its geometry table labels the wheel 26.7 inches, and the model uses that label, as RedTail's does; scaled by the 47.4-inch wheelbase, Freesky's own drawing puts the tires at 29.1 inches (RedTail's measurement). On that wheel the model gives about 135 km at 32 km/h in place of 139, and 181 km at 25 km/h in place of 185.

The arithmetic, one ride worked through

Take 25 km/h (6.944 m/s) on the throttle with a 90 kg rider: 130.8 kg moving with the bike. Rolling resistance takes 6.944 × 130.8 × 9.81 × 0.01054 = 93.9 W (the fat-tire median rolling coefficient) and the air 0.5 × 1.184 × 0.603 × 6.944³ = 119.5 W, so the wheel needs 213.4 W.

The motor delivers 75.52% of what it draws, so the packs give 213.4 ÷ 0.7552 = 282.6 W. The packs pass on 97.03% of their cells' energy, so the cells give 291.3 W, or 11.65 Wh per kilometre. 2,160 Wh ÷ 11.65 = 185 km in our model; keep 20% back and plan on 148 km.

Rider weight, hills, ground and wind

Modelled: flat pavement, 25 °C, both packs full. 181 kg is Freesky's full 400 lb load of rider and cargo.

Modelled: 90 kg rider, 25 °C. At 10 km/h the comparable motor holds up to a 19.8% grade on the throttle and 24.2% with 150 W of pedalling, on torque alone; tire grip, which the model leaves out, can give out first on loose ground. Our e-bikes for hills guide compares climbers.

Modelled. Gravel ratios from Meyer, Kloss and Senner (2016), measured on one four-wheeled electric bicycle; read them as a guide to the spread.

Riders report less than Freesky's band. Ryde Kulture, a YouTube tester who weighs 220 lb, rode one on pedal assist until the packs were empty and added up his legs as "45 + 35 is 80" miles; Spokes & Scenery, after about 1,000 km on his, said "you're never going to get that kind of range" Freesky advertises, "but you're going to get something respectable".

The two packs: charging and running on one

The Alaska Pro carries two removable 48 V packs, "18Ah up top and 27Ah below", and Freesky's battery FAQ says "The bike can operate with only one working battery." In our model at 25 km/h on the throttle, the 18 Ah pack alone gives about 74 km and the 27 Ah pack about 111 km.

Modelled: 90 kg rider, throttle only, flat pavement, 25 °C, both packs aboard with one empty (RedTail's basis); the watt-hours per kilometre are the whole bike's. Freesky's figures come from its dual-battery FAQ; its product page prints 98-175 miles for both packs.

Freesky supplies two chargers, "US Standard 3A Smart Charger + 2A Smart Charger", and its page says "98–175 miles on a single 8-10 hour charge". Its battery FAQ lets you "Charge both batteries at the same time", charge them one at a time or charge only one, and it recommends keeping both "at similar charge levels".

The manual Freesky links today says to charge only "between 0°C (32°F) and 40°C (104°F)" and to "Charge and store bike and battery in a dry location." It adds that a warm charger is normal: "As long as the temperature of the charger stays below 65°C (149°F), there's nothing to worry about." Our e-bike battery guide covers storage and care.

What does Canadian cold do to the Alaska Pro?

Cold costs range, and Freesky's two manuals draw the cold line in different places. The manual its pages link today says the bike is "not intended to be used and stored at ambient temperatures less than -20°C"; the earlier manual, which RedTail read in September, put that line at 0 °C. Both say to charge only between 0 °C and 40 °C.

At 0 °C our model gives about 145 km at 25 km/h on the throttle, against 185 km at 25 °C. At −10 °C the cold-cell sources put the same ride between 63 and 131 km in our model, inside today's manual window and outside September's.

Modelled: 90 kg rider, throttle only, flat pavement, no wind, both packs full. The central figure uses McMaster University's LG HG2 cell measurements; the span covers the cold-cell sources RedTail read for its cold-weather range ("none" where those sources start at 0 °C). "Manual now": −20 °C to 45 °C; "Sept. manual": 0 °C to 40 °C; charging: 0 °C to 40 °C in both. Below +5 °C the model holds tire resistance at its +5 °C value, so real winter figures run lower.

So the packs come indoors to charge whenever it is below 0 °C outside, under either manual. The current manual also says "Exposure to very wet, hot, or cold conditions may void the warranty.", so cold riding inside the window still carries that line. Our winter e-bike guide compares bikes built for snow.

Will the Freesky Alaska Pro fit you?

Probably, if you are under about 5′8″; measure first if you are taller. Freesky prints a 5′6″ to 6′8″ rider window, but on the seat height Freesky lists, the saddle reaches the fit formula's height for at least 8 in 10 of RedTail's 6,068 measured adults from 4′11″, the shortest height with 30 or more of them, to 5′6″; then 44 in 100 at 5′8″, 10 in 100 at 5′10″ and none from 6′1″.

The limit is the top of the seat. Freesky lists a saddle that rises to 40.7 inches (103 cm) off the ground, and the fit formula, 109% of inseam from the pedal, asks for more than that past an inseam of about 32.5 inches (83 cm), as RedTail's fit run shows. Above it you ride with the saddle at its highest and more bend in the knee.

Tall owners do ride it: RedTail quotes an owner who wrote on Freesky's page on January 15, 2025 that, at 6′2″, "it fits me perfect". Read that as one rider's comfort, with the saddle at its top.

Each figure is the share of measured adults at that height whose saddle can be set to 109% (or 106%) of their inseam within the 30.7 to 40.7 in seat range Freesky lists. Every row rests on 30 or more adults. ANSUR II measured US Army personnel aged 17 to 58 in 2010 to 2012, a population that differs from Canada's.

Freesky's drawing disagrees with its table at the low end: RedTail measured the lowest seat at 35.9 in (91 cm), not 30.7, and the standover line at 31.5 in, not 28.7. At the drawn lowest seat, the saddle meets 109% of an inseam of 27.9 in (71 cm).

The clearance that 95 in 100 riders at each height have or exceed over the top tube: "Listed" at the 28.7 in standover Freesky prints, "Drawn" at the 31.5 in line its drawing shows (RedTail's measurement). A minus sign means the frame sits above that inseam.

So an inseam of about 71 to 83 cm (27.9 to 32.5 in) suits both of Freesky's seat figures. On the listed standover, 95 in 100 riders clear the top tube from 5′3″ up; on the drawn line, from 5′9″ up. The frame has no step-through, so you swing a leg over it. Our e-bikes for tall riders guide lists bikes measured for longer legs.

Is the Freesky Alaska Pro street legal in Canada?

No. Every province that defines an e-bike stops at 500 W and, where it sets a speed, at 32 km/h; Freesky prints a 40 MPH (64 km/h) top speed and a 4,500 W peak motor with no rated power. So no province lets it ride roads, bike lanes or paths as an e-bike.

Quotations are from each province's statute, regulation or regulator page, saved on the day they were read. A province's page can change; follow the link before you ride.

That leaves private land, with the owner's permission, and trails where the land manager allows motorized vehicles. Trail rules are set park by park and club by club, so ask before you ride. Our Canadian e-bike law guide links each province's full page, including Ontario, Québec and British Columbia.

Is the Alaska Pro UL certified, and has it been recalled?

Partly, and no recall in Health Canada's or the US CPSC's records names Freesky or the Alaska Pro. Freesky's page shows "UL2849 Certified by TÜV" and "UL2271 Certified by TÜV (18Ah)", and the battery certificate behind the second badge covers the 18 Ah pack only.

Both certificates name GuangZhou Yansan Science & Technology Co.,LTD as the holder. Read 2 November 2026 from the PDFs Freesky's Canadian Alaska Pro page links; RedTail read the same two on 25 September.

No certificate for the 27 Ah pack appears on Freesky's Canadian or US page, its product records, the 138 images on those pages or its manual, all read on 2 November 2026. Check the labels on both packs when your bike arrives. The battery certificate says "The battery is used for off-road LEVs.", which matches where this bike can be ridden in Canada.

Each search ran beside a control that had to return results; a search that could not run is reported as not searched, never as none.

RedTail's CPSC screen on 25 September found nothing naming the Alaska Pro either. A clean recall record shows only what regulators have acted on, so the certificates and the manual's limits matter too.

How does the Alaska Pro compare with the Warrior Pro and the Tesway X7 AWD?

The Alaska Pro is the one-motor distance bike of the three, and the lightest on the makers' printed weights; the Freesky Warrior Pro adds a driven front wheel, and the Tesway X7 AWD carries a bigger pack on smaller wheels. Each maker figure below was read on 2 November 2026, and each computed figure uses one condition.

Maker columns: Freesky Canada's two pages and Tesway Canada's page, read 2 November 2026; Freesky prints a 400 lb (181 kg) load for both of its bikes, Tesway "180KG Max Load" and "a combined peak power of 3600W". Range: RedTail's computed figures for an 82 kg (180 lb) rider at 32 km/h (20 mph) on the throttle, flat pavement, 25 °C, every motor driving; for the 90 kg rider used elsewhere here, this review's model gives the Alaska Pro 139 km. Fit: the share of RedTail's measured adults whose saddle reaches 109% of inseam on each maker's listed seat range.

Our Freesky brand profile covers the whole Freesky line we sell, and our long-range e-bike guide sets these against other brands.

What do owners and testers report?

Testers like the range, the climbing and the price, and they report rough edges. Freesky's page shows 135 reviews; the riders below are independent YouTube testers, their words are theirs, and none is our measurement.

• Spokes & Scenery, after about 1,000 km: he weighed his at "87.1 lb without the fenders, the rear rack, any batteries" and over 100 lb with them; the rear shock "isn't really up to snuff", the kickstand broke and the tires were "already halfway worn"; and of Freesky's support, "the customer service wasn't really great".
• Ryde Kulture, on an earlier build with "48 volts with 41 amp hours": a pedal "just broke off" on his second day and the handlebar came loose, and he concluded "This bike just like totally failed me."
• TailHappyTV, in June 2024: in loose sand the "controller had a few minutes of cool off", the front fender rattled, and the bike climbed a 12% grade at about 21 mph.

Read each as one rider's bike, and two of the three rode earlier builds. Inspect every fitting at setup, and call us with anything loose before you ride.

Turning it on, and the manual

To switch it on, the display asks for an NFC card or a password. The manual Freesky links says to "use NFC to swipe the screen, or hold the power button and enter the default password: 1212 to turn on the bike."

The same manual sets the assist levels ("Level 0 indicates pedal assistance is inactive."), the braking rule ("Relying only on the rear brake will significantly increase your stopping distance."), the seatpost limit ("DO NOT raise the seat post beyond the minimum insertion marking") and the minimum age: "Riders must be at least 18 years old."

Freesky already prints 40 MPH on pedal assist, past the 32 km/h line in every provincial e-bike definition. We do not show how to change its speed, and for display settings beyond those in the manual, call us at 1-866-938-7580 before you change anything.

Who should buy the Alaska Pro, and who should skip it?

Buy it if you ride private land or permitted trails, want long range from one motor and two packs, carry real loads, and stand under about 5′8″ or have an inseam of about 71 to 83 cm. Skip it if you need roads, paths or bike lanes, are tall and want the saddle at the formula's height, or carry your bike up stairs.

The ledger sets out both sides.

That verdict is our opinion, formed from the facts above, and the facts are printed so you can reach your own.

Freesky Alaska Pro questions, answered

Is the Freesky Alaska Pro worth buying?

For distance on private ground, yes, in our view, if it fits you. It pairs one 4,500 W peak motor with two packs, 2,160 Wh together, full suspension and a 400 lb load rating for $2,749, and in our model those packs cover about 139 km at 32 km/h on flat pavement. Most riders from 5′8″ up run out of seatpost on RedTail's measurements, and no province treats it as an e-bike, so it suits private land and permitted trails.

How fast is the Freesky Alaska Pro?

Freesky's Canadian page prints "TOP SPEED (PAS) 40 MPH" (64 km/h) and "40MPH (Throttle & PAS)" in its comparison table, while its holiday guide prints "40MPH (pedal assist) / 20MPH (throttle)". Every provincial e-bike definition stops assistance at 32 km/h or less, so either way those speeds belong on private land or permitted trails. In our range model, built on a comparable 1,000 W motor, a 90 kg rider holds up to 47 km/h on the flat.

How far does the Freesky Alaska Pro go on one charge?

In our model, about 139 km at 32 km/h and 185 km at 25 km/h for a 90 kg rider on the throttle, on flat pavement at 25 °C with both packs full; keep a fifth in reserve and plan on 111 and 148 km. Freesky prints "98-175 Miles" (158 to 282 km); in our model the top end needs a steady 13 km/h on the throttle, or 25 km/h with a steady 75 W of pedalling.

Can the Alaska Pro run on one battery?

Yes. Freesky's battery FAQ says "The bike can operate with only one working battery", with "Pedal assist and throttle functions remain available". In our model at 25 km/h on the throttle, the 18 Ah pack alone gives about 74 km and the 27 Ah pack about 111 km, for a 90 kg rider on flat pavement at 25 °C.

How long does the Alaska Pro take to charge, and do both packs charge together?

Freesky supplies two chargers, "US Standard 3A Smart Charger + 2A Smart Charger", and its page says "98–175 miles on a single 8-10 hour charge". Its battery FAQ lets you "Charge both batteries at the same time", charge them one at a time or charge only one. The manual Freesky links asks you to charge only between 0 °C and 40 °C, so in winter the packs come indoors.

How much does the Freesky Alaska Pro weigh?

Freesky prints "E-BIKE WEIGHT 90 LBS" (40.8 kg), while its product record carries 108.0 lb in its weight field. One owner-tester weighed his at 87.1 lb without fenders, rack or batteries, and over 100 lb with them on. Plan on two people to lift it, and size any hitch rack for its weight.

Will the Freesky Alaska Pro fit a tall rider?

Most likely not at the full saddle height. Freesky prints a 5′6″ to 6′8″ window, but on the seat height Freesky lists, the saddle reaches the fit formula's height for at least 8 in 10 of RedTail's 6,068 measured adults from 4′11″, the shortest height with 30 or more of them, to 5′6″; then 44 in 100 at 5′8″, 10 in 100 at 5′10″ and none from 6′1″. An inseam of about 71 to 83 cm suits both of Freesky's seat figures; our e-bikes for tall riders guide lists bikes measured for longer legs.

Is the Freesky Alaska Pro street legal in Canada?

No. Every province that defines an e-bike stops at 500 W and, where it sets a speed, at 32 km/h; Freesky prints 40 MPH (64 km/h) and a 4,500 W peak motor with no rated power. So no province lets it ride roads, bike lanes or paths as an e-bike. Ride it on private land with the owner's permission, or on trails where the land manager permits motorized vehicles, and read our e-bike law guide for your province.

Can the Freesky Alaska Pro be unlocked?

To switch it on, yes: the manual Freesky links says to swipe the NFC card or enter the default password 1212. Its speed is another matter. Freesky already prints 40 MPH on pedal assist, past the 32 km/h line in every provincial e-bike definition, so whatever its setting, it is not an e-bike under any provincial rule. We do not show how to change its speed.

Does the Alaska Pro come with a rear rack and fenders?

Yes. Freesky's Canadian page lists the bike, the manual, a rear rack and front and rear mudguards under "What You'll Receive". One owner-tester weighed the bike at over 100 lb with the fenders, rack and batteries on, so check any hitch rack's rated load first.

Freesky Alaska Pro or Warrior Pro: which should I buy?

The Alaska Pro has one 4,500 W peak motor and 2,160 Wh; the Warrior Pro M-530 has two 2,000 W peak motors, 1,440 Wh and a driven front wheel for loose ground. For an 82 kg rider at 32 km/h on the throttle, RedTail's computed ranges give the Alaska Pro 140 km and the Warrior Pro 93 km. Choose the Alaska Pro ($2,749) for distance, or the Warrior Pro ($2,899) for two driven wheels; our Warrior Pro review covers it.

Is the Alaska Pro UL certified, and has it been recalled?

Its electrical system is: TÜV SÜD's UL 2849 certificate names the M-520. The UL 2271 battery certificate Freesky shows covers the 18 Ah pack only, and we found no certificate for the 27 Ah pack on Freesky's pages, records, images or manual. No recall in Health Canada's or the US CPSC's records names Freesky or the Alaska Pro.

What changed on the 2025 and 2026 Alaska Pro?

Freesky's own pages print different figures across time: 4,500 W peak and 170 N·m on its product page today, 4,000 W and 160 N·m in two of its guides, 3,000 W in its holiday guide, and 2,500 W with a 48V 41Ah (1968Wh) pair in an older post. Its battery FAQ says packs come as 18 Ah + 23 Ah or 18 Ah + 27 Ah "Depending on production batch and configuration". The labels on your own packs and frame settle which build you have.

How much power and torque does the Alaska Pro have?

Freesky's page prints "4500W Peak Brushless Motor" and "170N·m Torque", from one rear hub motor. Peak is a short burst. Freesky prints no rated (continuous) power for the Alaska Pro on its pages, its product records, the images on its page or its manual, all read on 2 November 2026, and most provincial e-bike definitions are written around continuous power.

Where can I find the Alaska Pro manual and display settings?

Freesky's Canadian and US pages link the Alaska Pro M-520 user manual (PDF), a file dated 19 October 2026. It covers turning the bike on, the assist levels, assembly, charging between 0 °C and 40 °C and Freesky's warranty conditions. For display settings beyond those, call us at 1-866-938-7580 before you change anything.

Where do I get Alaska Pro parts, such as brake pads?

Call us at 1-866-938-7580. We handle warranty claims with Freesky for bikes bought from us, and Freesky's Canadian terms cover the motor, battery and controller for 24 months and other components for 12. The brakes are "180MM 4-piston Hydraulic Brakes", so take that to a shop if you buy pads locally.

How much does the Freesky Alaska Pro cost in Canada?

$2,749 at Zeus in Black, Green and Navy, with free shipping across Canada and our 15-day return policy on unused, unopened bikes, less a 15% restocking fee. Freesky's warranty is backed by Freesky in full, we handle the claim, and financing is available.

Does cold weather affect the Alaska Pro battery?

Yes. In our model the 25 km/h throttle ride drops from 185 km at 25 °C to about 145 km at 0 °C; at −10 °C the cold-cell sources put it between 63 and 131 km, inside the −20 °C use line in the manual Freesky links today. Under that manual and the September one, the packs charge only between 0 °C and 40 °C.

Is Freesky a good brand?

Freesky sells a full line in Canada, and we sell several of its bikes. For the Alaska Pro, its UL 2849 certificate names the model, no recall at Health Canada or the US CPSC names Freesky, and its Canadian warranty covers the motor, battery and controller for 24 months. Testers report rough edges, set out in the owners section; our Freesky brand profile covers the whole line.

The bottom line

The Alaska Pro gives you two removable packs with 2,160 Wh, a 400 lb load rating and full suspension for $2,749: about 139 km at 32 km/h on flat summer pavement in our model. It belongs on private land and permitted trails, with its packs charged indoors between 0 °C and 40 °C.
