Addmotor Citytri E-310 Folding Electric Trike

Addmotor Citytri E‑310: a Folding Electric Trike With a 35 cm Step-Over, a Rear Differential and a 48 V 20 Ah UL-Certified Battery

The Addmotor Citytri E‑310 is a folding, step-through electric tricycle for adults: two rear wheels joined by a differential, a seat with a backrest, a rear basket, and a frame that folds to fit a car trunk. Addmotor Canada lists a 500 W rear-drive motor (1,100 W peak, 90 N·m), a 48 V, 20 Ah battery certified to UL 2271, a trike certified to UL 2849, a 32 km/h top speed and up to 145 km of range in the lowest assist level.

It comes in two sizes. The Standard (20″ front and 18″ rear wheels) steps over at 35 cm and fits riders 155–175 cm (5′1″–5′9″); the Plus (22″/20″ wheels, an upright handlebar) steps over at 40.6 cm and fits 160–185 cm (5′3″–6′1″). At 39 kg with the battery, it is the lightest of the four Addmotor trikes we compare below, and Addmotor rates it for a 127 kg rider plus 36 kg of cargo.

Who it suits: riders who want three wheels for balance, a low step for stiff hips or knees, and a trike that folds into a car or a small storage room. Addmotor’s own words: “Perfect for seniors, those with mobility challenges.” Our Citytri E-310 review covers how it rides; this page has every figure Addmotor publishes, both size charts, and what comes in the box.

Watch Addmotor’s Citytri E‑310 Assembly and Operations Video

Addmotor’s own assembly and operations video for the Citytri E‑310: unboxing, unfolding the frame, fitting the parts that ship loose, and the display and controls. Addmotor says the trike arrives 85% pre-assembled and points buyers to this video for the rest. We did not make it.

“Addmotor CITYTRI E-310 Electric Trike Assembly Tutorial & Operations Guide” (14:36, uploaded 8 August 2024), from Addmotor’s own YouTube channel, not made by Zeus.

What the Combination Does for a Canadian Rider

• Balance without a kickstand moment. Three wheels stand on their own at a stop, the parking brake holds the trike on a slope, and the differential lets the two rear wheels turn at different speeds through a corner, which Addmotor says keeps turning smooth.
• A low step for stiff joints. 35 cm on the Standard is lower than two of the three other Addmotor trikes we compare below; only the SpytanX (28.4 cm) is lower. The Grandtan II’s is 44.5 cm and the Arisetan II’s 67.8 cm.
• It fits where you keep it. Folded, the Standard is 115 × 86 × 72.9 cm; Addmotor says it fits in the trunk of a car, and its answer to a buyer’s question is that it fits most SUVs. At 39 kg, plan on two people to lift it.
• One battery, all the errands. 48 V × 20 Ah is 960 Wh by our arithmetic, the same capacity as the other three trikes in the comparison below, on the lightest frame of the four.

Citytri E‑310 Dimensions: Standard and Plus

Addmotor publishes these measurements for both sizes; the drawing shows where each one is taken. Inches and centimetres are Addmotor’s own (its figures are rounded differently in a few rows, and we print them as published).

Overall width is 71.9 cm (Standard) or 73.7 cm (Plus). Measure your doorways, gate and storage space against these figures, unfolded and folded, before you order.

Key Features

• 500 W rear-drive motor (1,100 W peak, 90 N·m) — the motor drives the rear, and Addmotor says rear-mounted motors give better traction, stability and handling than the front-motor trikes it stopped making. A half-twist throttle and 7 levels of pedal assist share the job.
• 48 V, 20 Ah Samsung battery, UL 2271 — Addmotor describes it as UL-certified for the US and Canada and rates it at up to 145 km in PAS 1. It charges on the 48 V, 2 A charger with a magnetic 5-pin plug.
• UL 2849 trike system — Addmotor says UL 2849 tests the whole electrical system (motor, controller, battery and charger) against heat, overload and short circuits. It matters most if the trike is stored or charged indoors.
• Folding step-through frame (7020 + 6061 aluminum) — a 35 cm step on the Standard, and a fold Addmotor says fits tight spaces or a car trunk.
• Rear differential and parking brake — the differential lets the rear wheels turn at different speeds in a corner; the parking brake holds the trike when you stop on a hill.
• Seat with an adjustable backrest — a lower seating position with a backrest that adjusts up and down, per Addmotor.
• 80 mm suspension fork — front suspension to take the edge off curbs, cracks and gravel paths.
• Tektro mechanical disc brakes on all three wheels — cable-operated discs on both rear wheels and the front.
• Lights on the main battery — a headlight, and a 5-in-1 taillight with brake light and turn signals.
• 5-inch LCD display, 25 A controller, KMC stainless chain, double-wall rims — Addmotor’s parts list for the drivetrain and electronics.

What’s Included

Addmotor says the Citytri arrives 85% pre-assembled. In the box, per Addmotor’s own answer to “What’s inside the box?”:

• The Citytri E‑310 trike (Standard or Plus)
• The 48 V 20 Ah battery and the 48 V 2 A charger
• The free Citytri Pack: mirrors, the rear rack (rear basket), a cleaning tool and a bike pump

Not included: the front basket. Finish the build with Addmotor’s video above; your first month of Zeus Care includes assembly walkthroughs by phone or video.

The Honest Take: What to Know Before You Buy

1. Cadence sensor, not torque. The assist responds to the pedals turning, not to how hard you push, so it comes on at a set level rather than matching your effort. The Grandtan II, Arisetan II and SpytanX all use torque sensors.
2. Mechanical, not hydraulic, brakes. Tektro cable discs on each wheel need periodic cable and pad adjustment as the pads wear; hydraulic discs adjust themselves. The SpytanX is the Addmotor trike we carry with hydraulic discs.
3. 39 kg is light for a trike, not for lifting. Folding gets it into a trunk or SUV, but plan on two people to lift it in. And for riders over 185 cm, neither size fits Addmotor’s chart: the Grandtan II (to 193 cm) and Arisetan II (to 198 cm) do.

If those fit how you ride (errands, paved paths, neighbourhood loops, a trike that folds away), the Citytri E‑310 is the lightest of the four Addmotor trikes compared on this page, and one of the two that fold.

Who Is the Citytri E‑310 For?

• Seniors and riders with balance worries — three wheels, a backrest and a 35 cm step. E-bikes and trikes for seniors →
• Riders with stiff hips or knees — step through instead of swinging a leg over; the Standard’s saddle goes as low as 74.9 cm.
• Errand runners — the rear basket (45.7 × 40.6 × 20.3 cm) carries groceries, within the 36 kg cargo rating. Electric trikes in Canada →
• RV, condo and small-space owners — it folds to 115 × 86 × 72.9 cm (Standard). Folding e-bikes in Canada →

Who it’s NOT for: riders over 185 cm (the Grandtan II fits to 193 cm, the Arisetan II M-360 to 198 cm); riders over 127 kg (the Grandtan II is rated 159 kg + 45 kg cargo, see e-bikes for heavy riders); anyone who wants a torque sensor or hydraulic brakes (the SpytanX has both); and anyone in Yukon, the Northwest Territories or Nunavut, where it does not ship.

How It Compares With Three Addmotor Trikes at Zeus

Four Addmotor trikes at Zeus, October 2026. 🏆 marks the row winner, including rows the Citytri loses; ✓ marks where the Citytri beats at least one of the others. Every figure is Addmotor Canada’s, from its product pages read 17 October 2026. Scroll right on mobile.

N/P = not published on that trike’s Addmotor Canada page (Addmotor’s Canadian pages print the Citytri’s wattage; the SpytanX’s appears only in its FAQ, as 250 W, and Addmotor’s US page prints 750 W). *SpytanX: Addmotor lists 47 kg next to 109 lb (49.4 kg), a payload of “380 LBS / 127 KG” (380 lb is 172 kg), and rider heights of 149–180 cm beside 4′9″–5′9″ (145–175 cm); we print both of Addmotor’s figures, and Addmotor is the one to confirm them.

Frequently Asked Questions

What riders ask about the Citytri E‑310

Is the Addmotor Citytri E‑310 500 W or 750 W?

Addmotor’s Canadian store lists the Citytri at 500 W (rear drive, 1,100 W peak, 90 N·m). Addmotor’s US store lists a 750 W Citytri, which is why US reviews quote more power. Both use the same 48 V 20 Ah battery. Why 500 W matters in Canada →

What’s the difference between the Citytri Standard and Plus?

Wheel size, fit and handlebar. The Standard has 20″ front and 18″ rear wheels, a regular handlebar, a 35 cm step-over and fits 155–175 cm riders; the Plus has 22″/20″ wheels, an upright handlebar, a 40.6 cm step-over and fits 160–185 cm. Addmotor says the bigger wheels make the Plus better for taller riders. Motor, battery and brakes are the same. Compare both sizes →

Does the Citytri E‑310 fold, and will it fit in my car?

Yes. Folded, the Standard measures 115 × 86 × 72.9 cm and the Plus 124.5 × 87.6 × 94.7 cm. Addmotor says it fits in the trunk of a car, and its answer to a buyer’s question about transport is that it fits most SUVs. It weighs 39 kg with the battery, so plan on two people to lift it, and measure your cargo space against the folded size.

Is the Citytri a good electric trike for seniors?

Addmotor designed it for that rider: a low step-through frame (35 cm on the Standard), a seat with a backrest, three wheels that stand on their own, and a parking brake. Its own description reads “Perfect for seniors, those with mobility challenges.” Check fit first: the Standard suits 155–175 cm riders. E-bikes for seniors →

How far does it go on a charge?

Addmotor rates it at up to 145 km (90 mi) in pedal-assist level 1, the lowest of seven. Using more assist or the throttle, carrying cargo, hills, wind and cold all shorten that; our own estimate for mixed riding is about 40–65 km (960 Wh at an assumed 15–25 Wh/km, not a measured figure). Our e-bike battery guide →

How much weight can it carry?

Addmotor rates it for a 127 kg (280 lb) rider plus 36 kg (80 lb) of cargo. The included rear basket measures 45.7 × 40.6 × 20.3 cm. For a heavier rider, the Grandtan II is rated 159 kg + 45 kg.

What comes in the box, and are the baskets included?

The trike, the battery and charger, and the free Citytri Pack: mirrors, the rear rack (the rear basket), a cleaning tool and a bike pump. Addmotor says the front basket is not included. It arrives 85% pre-assembled.

How hard is assembly?

Addmotor says it arrives 85% pre-assembled and points buyers to its assembly video (on this page) for the rest. Your first month of Zeus Care includes assembly walkthroughs by phone or video, and you can call us at 1-866-938-7580.

Does it have a throttle, and can I ride without pedalling?

Yes. It has a half-twist variable-speed throttle alongside 7 levels of pedal assist, and Addmotor’s answer to a buyer is that you can ride on the throttle alone. Throttle rules differ by province. Canadian e-bike laws →

How many gears does the Citytri have?

Addmotor’s Canadian spec table lists no derailleur or gear count (its Grandtan II and SpytanX pages list Shimano 7-speed gearing). On its US product Q&A, an answer posted by an Addmotor customer says one speed. If gears matter to you, call us before you buy.

Will the seat and backrest work for a taller rider?

Addmotor says the backrest adjusts up and down. The Plus raises the saddle range to 78.7–96.5 cm and fits riders to 185 cm (6′1″); above that, Addmotor’s chart points to a bigger trike, such as the Arisetan II M-360 (170–198 cm).

Is the Citytri safe to store and charge indoors?

Addmotor lists the trike as certified to UL 2849, which tests the whole electrical system (motor, controller, battery and charger), and the battery to UL 2271. Charge it with the supplied 48 V 2 A charger. Battery care and storage →

Where does it ship, and how long does delivery take?

Free shipping across Canada. It ships within 2–10 business days of order confirmation, by FedEx, UPS or Purolator, and tracking is emailed when it ships. It cannot ship to Yukon, the Northwest Territories or Nunavut, and an adult (18+) must sign for it at delivery.

What warranty comes with the Citytri E‑310?

Addmotor’s published warranty (read 17 October 2026) covers the frame for 2 years, the motor for 2 years and the 20 Ah battery for 2 years. Original parts (the fork, stem, handlebar, headset, seat post, lights, bottom bracket, rims, wheel hubs, derailleur, throttle, wiring harness, controller and LCD display) are covered for 1 year. Addmotor notes the battery lasts about 800 charge cycles. Not covered, in Addmotor’s words: normal wear and tear; consumables (tires, tubes, brake pads, rotors, bearings, stripped threads and bolts, cables, grips, chains, cassettes and spokes); theft; and damage from misuse, accidents, improper assembly or maintenance, commercial use, modifications, corrosion or water damage. Coverage is for the original owner and does not transfer. Your Citytri carries Addmotor’s published terms in full, and Zeus handles every claim with Addmotor for you. Your first month of Zeus Care is included: we diagnose the problem, file the claim and follow it up.
