Eunorau ONE-TRIKE 2.0 Review 2026: 440 lb, 36in Wide

500 W rear drive with a differential · 696 Wh · 20 MPH · 440 lb payload · 85.98 lb · 36.22 in wide · $1,799 · verified September 7, 2026

Quick Answer — The Eunorau ONE-TRIKE 2.0 is a $1,799 three-wheeler with a 500 W rear-drive motor, a rear differential, 696 Wh of battery and a published 440 lb payload. It is a throttle trike: one gear, 20 MPH, and pedals geared for gentle help; keeping up is the throttle's job.

Buy it if you want the stability of three wheels and a cargo bed without paying $2,499 for our folding NEW-TRIKE 2.0. Measure your doorway first — at 36.22 inches it is wider than a standard interior door.

How we verified this Eunorau ONE-TRIKE 2.0 review

Every figure here is Eunorau's published specification, verified against its own spec table on September 7, 2026 and recomputed where the arithmetic could be checked. Two independent retrievals were taken — the rendered product page and the storefront's own product feed — and diffed against each other, because Eunorau's feed and page have disagreed on top speed on other models. On this machine they agree, on all seven load-bearing rows.

Prices, colorways and stock come from our own store through the Shopify Admin API on the same date. The recall check ran against the CPSC's own database and was control-tested before its result was believed. The arithmetic in the range, gearing and charge-time sections is ours, and the script that produces it is committed with this page.

The two trikes the engines keep confusing

If you have been researching this trike through an AI assistant, check which machine the answer is about. Ask about the ONE-TRIKE 2.0 and the two most authoritative sources that come back — Ride Review and Electric Bike Review — are both reviewing the NEW-TRIKE, a different Eunorau trike at a different price.

We ran that panel on 2026-09-07 and saved the raw output. Of ten sources returned, every one was the manufacturer, a retailer, or a review of the other trike. There is no independent editorial review of the ONE-TRIKE 2.0 anywhere.

The two are genuinely different machines — this one and the other — and the differences decide the purchase:

The shape that tells the two trikes apart: a fixed frame with the cargo bed slung between the rear wheels, and a step-through so low you walk into it instead of over it.

The ONE-TRIKE carries 72.5% of the other trike's energy for $700 less, and spends part of that saving on a differential the more expensive trike does not have. What it gives up is gears, three and a half inches of width, and a frame that folds.

What a rear differential actually buys

On a trike, the outside rear wheel travels further than the inside one through every turn. A single-wheel-drive trike sidesteps that by powering one wheel only, which pulls to one side under throttle. A locked axle drives both and makes the pair fight each other, which is the hopping and chirping you hear from cheap trikes on tight corners.

The rear axle and the cargo bed above it. Both back wheels are driven through the differential, which is what stops the pair fighting each other in a tight turn.

A differential lets the two rear wheels turn at different speeds while both still receive power. Eunorau publishes one on this machine and describes its job in its own words: it "enables the rear wheels to adapt to varying speeds and terrains, minimizing slippage and hopping."

The differential is the most consequential thing on the specification, and the reason this trike costs more than the $1,499 machines it sits beside. It is also the thing to test on your first ride: turn tightly under power in both directions and feel whether the back end tracks or skips.

The motor itself is a 48 V, 500 W rear-drive unit rated at 80 N·m. The controller is rated 48 V / 20 A, so the peak the electronics will pass is around 960 W — roughly double the nominal figure, which is ordinary and is what gets a loaded trike moving from a standstill on a rise.

One gear, and what it means for pedalling

This is a throttle machine, and the gearing is the proof. Eunorau publishes a single-speed drivetrain: a 38-tooth chainring driving an 18-tooth freewheel, on a 20-inch wheel with a 2.6-inch tire.

Run that out. A 406 mm bead seat with the published 2.6-inch tire gives an outside diameter of 538 mm and a rolling circumference of 1.69 m. The gear ratio is 38 ÷ 18 = 2.11. So:

At the published 20 MPH top speed you would need to spin 150 rpm to stay with the pedals. Nobody does that on a utility trike carrying groceries. Below about 12 mph the pedals contribute usefully; above it they are along for the ride and the throttle is doing the work.

The cockpit: hydraulic levers with a motor cut-off, an adjustable stem that folds, and the front basket sitting on the head tube instead of the bars, so a heavy load does not fight the steering.

Read that as a description. It is not a complaint. A single-speed drivetrain has no derailleur to knock out of alignment, no cassette to wear, and nothing to adjust — which on a machine bought for reliability is a fair trade. But if you pictured pedalling this at 18 mph for exercise, the gear it ships with will not let you, and the NEW-TRIKE 2.0's seven speeds are the reason that trike costs $700 more.

696 Wh against a 50-mile claim

Plan on 20 to 30 miles, not 50. Eunorau publishes a 48 V, 14.5 Ah pack, and volts times amp-hours is the only honest measure of stored energy: 48 × 14.5 = 696 Wh.

Set the published claim against it. Fifty miles from 696 Wh requires 13.9 Wh per mile. A light rider on flat ground at the lowest assist level can approach it. It is not a number that describes an 86 lb trike carrying a shop.

Packs also cut off before true zero, cold weather taxes them and capacity fades, so about 85% is usable — 592 Wh here. Divide that by honest consumption:

Twenty to thirty miles is a genuinely useful figure for a shopping and errand machine, against a published claim of fifty — it is several days of typical use between charges. It is not the fifty on the page, and knowing which number you are planning around is the difference between a trike that works and one that strands you.

Charging follows the same arithmetic. The published charger is a 2.0 A unit, so at 48 V it delivers roughly 96 W to the pack. Refilling 696 Wh at that rate takes about 7.25 hours before charging losses. Plan on an overnight charge; a lunchtime top-up will not do it.

36.22 inches: the doorway test

Measure the narrowest gap between where this trike will live and the road, before you order. The rule that decides it is a doorway standard, and it has nothing to do with bicycles. Eunorau publishes a maximum width of 920 mm — 36.22 inches. That number decides more purchases than the motor does, and no round-up we found mentions it.

Seen from the front, the track across the back axle is the dimension that decides where this trike can live. It is 36.22 inches, and it does not shrink.

A standard US interior door leaf is 32 inches nominal and gives roughly 30 to 31 inches of clear opening. The accessible minimum written into the ADA standards is 32 inches of clear width — § 404.2.3 requires door openings to provide "a clear width of 32 inches (815 mm) minimum." This trike is 4.22 inches wider than that 32-inch clear opening and will not pass through it.

What it means in practice, in the order people discover it:

• A standard interior or garage side door: no. It goes in through a garage main door, a double door, or a gate.
• A car rack: check the rating and the width. Total length is 68 inches and it weighs 85.98 lb.
• Bike lanes and paths: usually fine, bollards are the risk. Path bollards and chicanes are frequently set at 36 inches or narrower, and a 36.22-inch trike does not fit through a 36-inch gap.
• Apartment corridors and elevators: measure both.

Our NEW-TRIKE 2.0 publishes 32.7 inches and folds, which is the answer if the storage problem is the binding constraint rather than the price.

Is it street legal? The federal text names three wheels

Yes, in federal terms, and the statute says so in words most pages never quote. When we asked an AI engine whether electric trikes are street legal, nine of nine sources it returned were retailer or manufacturer blog posts. Not one quoted the law.

The operative language, read at the primary source, settles it:

the term "low-speed electric bicycle" means a two- or three-wheeled vehicle with fully operable pedals and an electric motor of less than 750 watts (1 h.p.), whose maximum speed on a paved level surface, when powered solely by such a motor while ridden by an operator who weighs 170 pounds, is less than 20 mph.

Three-wheeled is in the definition by name. The ONE-TRIKE 2.0 has three wheels, fully operable pedals and a 500 W motor, so on the federal test it is a low-speed electric bicycle and is regulated as a consumer product and never as a motor vehicle.

Two qualifications matter, and they are the reason to read your own state's page before you stop here.

The federal line is "less than 20 mph" motor-only, and Eunorau publishes "20 MPH under speed limited/locked." A machine sitting exactly at the line rather than below it is worth a moment's thought if your state's wording is strict. In practice most states write their own definition at 20 mph and treat a throttle machine at that speed as Class 2.

State definitions say "bicycle," and whether that includes a tricycle is a state-by-state question. Our 50-state e-bike law guide carries each state's definition with the statute linked. Check yours against this machine's 500 W and 20 MPH before you ride it anywhere you would not push it.

The Mercer fit test

The Mercers are our editorial cast — a fixed group of American riders of different ages, heights and lives that every machine on this site is measured against. Every verdict reads a published number.

The figures doing the work, all from the maker's own table: the published 5'2"–6'1" rider range, the 32.3"–38.6" saddle-to-ground height, 85.98 lb, a 440 lb payload, 36.22 in of width, and one gear.

The backrest is the part that reads as a mobility aid and rides as a comfort feature. The saddle drops to 32.3 inches from the ground, which is what puts Ruth's feet down flat.

Read Ruth's row twice. She is the buyer this trike is built for, and the thing most likely to stop her is not the motor, the range or the price. It is a door. That is why the width section sits above the specification on this page.

If two wheels would do, the Eunorau META26 is the same 500 W and 20 MPH in a step-through city frame at $1,699, with a torque sensor and 68.4 lb against this trike's 85.98 — the lighter, cheaper answer for a rider who does not actually need the third wheel.

Has it been recalled?

No. Searching the CPSC's own recall database on September 7, 2026 returns no record naming Eunorau.

That sentence is only worth something if the search was real, so here is the check behind it. The same endpoint, queried the same way on the same day, returns one record for Ancheer, one for VanMoof, nineteen for "electric bicycle" and six for "tricycle." The database answers; it simply has nothing filed under this brand.

Two limits on what that establishes. A recall database records recalls, not the absence of defects, so a brand can have field failures that never reach a formal action. It also indexes only what is filed with the CPSC. What the check does establish is that Eunorau has not been the subject of a formal US recall action, which is a different position from several brands in this price band.

Is it UL certified?

Eunorau publishes a UL 2849 and UL 2271 testing announcement covering its e-bikes, and describes both certificates as voluntary. UL 2849 covers the electrical system as a whole — drive train, battery and charger together. UL 2271 covers the battery pack on its own.

This matters beyond peace of mind if you live in the wrong place with the wrong bike — the fire numbers behind the rule are why it exists.

Illinois requires certified drive systems and batteries at the point of sale, and New York City bars the sale, lease or rental of an e-bike or battery that is not certified to those standards. If you charge indoors — an apartment, a hallway, near a bedroom — it is the specification to check before the motor wattage.

If a per-model certificate is what your building or your insurer wants to see, ask us before you order and we will request it from Eunorau in writing.

Green flags / Red flags

Green flags

• A rear differential at $1,799, which is the mechanism that stops a powered trike hopping and pulling through tight turns, and which the machines either side of this price do not publish.
• A 440 lb published payload, matching our $2,499 trike and beating the 415 lb published by the trike the 2026 round-ups name as their top pick.
• Hydraulic disc brakes on 180 mm rotors with a motor cut-off, on a machine whose mass and cargo capacity genuinely need them.

Forty millimetres of front travel and a 180 mm rotor. On a machine that can carry 440 lb, the brake matters more than the fork does.

• Zero CPSC recall records, established against a control-tested query, never an unverified search.
• A 10-year frame warranty and 24 months on battery, motor and electrical components for any bike bought new — the terms are set out in full in our Eunorau brand profile.
• A single-speed drivetrain with nothing to adjust, which on a utility machine is a maintenance saving and not a compromise.

Red flags

Read this column as a fit test. Each line is a rider this trike is the wrong answer for, and where to go instead.

• Wrong if it has to live behind a standard door. At 36.22 inches it does not pass a 32-inch clear opening. Our NEW-TRIKE 2.0 publishes 32.7 inches and folds.
• Wrong if you want to pedal for exercise at speed. One gear puts comfortable pedalling at about 9 mph; the seven-speed NEW-TRIKE 2.0 is the machine for that.
• Wrong if your route has 36-inch bollards or narrow lane pinch-points. Measure the route before the garage.
• Wrong if you need 50 real miles between charges. Plan on 20 to 30 here; the 960 Wh NEW-TRIKE 2.0 is the longer-legged trike.
• Wrong if the rider is not the constraint you think. If the buyer is an older rider weighing three wheels against a low step-through, our guide for senior riders works through that choice first.
• Wrong if two wheels would do. If balance is not your limiting factor, a step-through like the FLASH LITE ST is lighter, narrower, cheaper to store and faster.

Buy it if / Buy something else if

Buy it if you want three wheels for stability, a real cargo capacity, and a powered rear axle that behaves in corners — and you have somewhere wide enough to keep it. At $1,799 it is the cheapest way onto a differential-equipped trike we sell, and for a rider whose alternative was giving up cycling, that is the whole argument. See it in all three colorways.

Buy something else if storage is tight, if you want to pedal hard, or if you need the longer range. See the full Eunorau range, or every electric trike we stock, to compare them side by side. In every one of those cases the answer is our own NEW-TRIKE 2.0 at $2,499 — narrower, folding, seven gears, 960 Wh — and the extra $700 buys exactly those four things and nothing else you are missing here. If it is real cargo capacity on two wheels rather than three, the G30-CARGO publishes 440 lb of payload.

Before you buy: the checklist

1. Measure the narrowest opening between the road and where the trike will sleep. If it is under 36.5 inches, this is not your trike.
2. Walk or drive your regular route and look for bollards, chicanes and gate gaps. Anything at 36 inches or less blocks you.
3. Check your state's definition against 500 W and 20 MPH in our 50-state guide, and confirm whether it treats a tricycle as a bicycle.
4. Plan on 20 to 30 miles per charge and an overnight refill. The published 50 assumes conditions your errands will not have.
5. Decide about gears now. If you want to pedal above 12 mph, buy the seven-speed NEW-TRIKE 2.0 instead.
6. Ask us for a per-model UL certificate if your building, insurer or state requires one.
7. Register the bike the day it arrives — Eunorau's warranty is conditioned on it and does not transfer to a second owner.

Frequently asked questions

How fast does the Eunorau ONE-TRIKE 2.0 go?

Twenty miles per hour, which Eunorau publishes as "20 MPH under speed limited/locked." That is throttle speed. Pedalling speed is a different number: with one gear at a comfortable 70 rpm cadence you are doing about 9.3 mph, and staying with the pedals at 20 mph would take a 150 rpm cadence.

Are electric trikes street legal in the US?

Federally, yes, when they meet the definition — and the federal text names three-wheeled vehicles explicitly, which almost no page quotes. At 500 W and 20 MPH with operable pedals this trike is inside it. State definitions are written separately and say "bicycle," so check whether yours covers a tricycle in our 50-state guide.

Are electric trikes safe, or are they more dangerous than a bike?

Three wheels remove the balancing that ends most older riders' cycling, which is the safety case for them. This one publishes a differential as well. The trade is cornering: a trike does not lean, so it must be ridden more slowly into turns than a bicycle, and a powered trike without a differential can hop or pull under throttle. This one publishes a differential.

How far does it really go on a charge?

The pack is 48 V × 14.5 Ah = 696 Wh. About 85% of that is usable, so 592 Wh. At 20 to 30 Wh per mile that is 19.7 to 29.6 miles. The published "up to 50 miles" would require 13.9 Wh per mile, which is a light rider, flat ground and the lowest assist level.

How long does it take to charge?

About 7.25 hours before charging losses. The published charger is 2.0 A, which at 48 V delivers roughly 96 W into a 696 Wh pack. Treat it as an overnight charge.

How much does an electric trike cost, and is this one good value?

This one is $1,799. The trikes the AI round-ups name as best-in-class sit around $1,499 to $2,500. What this price buys that the cheaper machines do not publish is a rear differential and a 440 lb payload.

What is a rear differential on an electric trike, and do I need one?

It lets the two rear wheels turn at different speeds while both receive power. Without one, a trike either drives a single wheel and pulls to that side, or drives both on a locked axle and skips through corners. On a machine you will turn tightly in car parks and driveways, it is the mechanism that decides how it feels.

Can it carry a passenger or a back seat?

No. It publishes a 440 lb total payload capacity, which is rider plus cargo plus accessories — our guide for heavier riders explains how to read that number against your own weight — and it ships with a saddle and backrest for one rider. Front and rear baskets are what the capacity is for.

Will it fit through my door?

Almost certainly not. Its published maximum width is 36.22 inches, and a standard interior door gives about 30 to 31 inches of clear opening — the accessible minimum is 32 inches. It needs a garage main door, a double door or a gate.

How heavy is it, and can I lift it onto a rack?

It weighs 85.98 lb and is 68 inches long. Treat it as a two-person lift, and check that any car rack is rated for the weight and wide enough for the rear axle.

Is Eunorau a good brand?

On the checkable measures it holds up for the price band: trading since 2009, a Nevada corporation, no CPSC recall records, a UL 2849 and 2271 testing announcement, and a 10-year frame warranty on bikes bought new. Our Eunorau brand profile censuses all 31 models we sell.

Does it fold?

The stem folds for height and angle adjustment and to make the machine shorter to store. The frame does not. If you need a trike that folds down, that is our NEW-TRIKE 2.0.

What tires does it use, and are they fat tires?

Twenty by 2.6 inch — a wide, cushioned tire; fat starts around 4 inches. On a trike the extra width matters less than it does on two wheels, because stability is coming from the third wheel rather than from the contact patch.

Limitations of this review

1. Every performance figure is Eunorau's published specification, verified against its own spec table on 2026-09-07 and recomputed where the arithmetic allowed. The range, gearing, charge-time and width computations on this page are ours and the script is committed with it.
2. The gearing table assumes an ETRTO 406 mm bead seat, the standard for a 20-inch wheel, with the published 2.6-inch tire. A different rim standard would shift the speeds by a few percent and leave the conclusion standing.
3. Eunorau publishes the tire as 20 × 2.6 in, and this page uses that figure. The studio photography shows a wide-profile knobby tire that reads visually broader than 2.6 inches; we publish the maker's number instead of a measurement taken off a photograph.
4. Eunorau publishes no cell brand for this pack, where it names Samsung cells on the NEW-TRIKE 2.0. That is a fact about the published record on the day it was read.
5. No charge time is printed for this model. The 7.25-hour figure is computed from the published 2.0 A charger and the published pack; Eunorau prints no charge time for this model.
6. The AI-search panel ran on one accessible instrument and is labelled as exactly that. ChatGPT, Perplexity and Google AI Overviews were not reachable from this session.
7. We sell this trike. Read everything above knowing that, and check the method beside every number instead of trusting us.

What will age this page: a specification change by Eunorau, which is published unilaterally and without notice; a price or stock move on either our listing or the maker's; a first CPSC filing naming the brand, which would change the recall section materially; any state adopting or amending a definition that decides whether a tricycle is a bicycle; and our own re-verification cadence — every claim here is re-checked at most six months out, due again by 2027-03-07.

The bottom line

The ONE-TRIKE 2.0 is the cheapest differential-equipped trike we sell, and the width is the decision. At $1,799 you get three wheels, a powered rear axle that behaves in corners, hydraulic brakes on 180 mm rotors, and a 440 lb payload that beats the machine the AI round-ups call best in class.

What you give up against our $2,499 trike is gears, 264 Wh of battery, three and a half inches of width, and a frame that folds down for storage. If none of those four is binding for you, the $700 stays in your pocket and the differential comes with it.

Dark Charcoal, one of three colorways in stock.

Snow White. Twenty-five units of each colorway on the day this page was verified.

If you are choosing between trikes instead of between this trike and a bicycle, our electric trike guide for the US sets the whole category side by side.

For Ruth's problem — a rider who wants to keep riding and cannot balance a two-wheeler at every stop — this is the answer on this site, provided there is a wide enough way to get it to the road. Measure that first, then buy with confidence.
