Eunorau URUS 2.0 Review 2026: 120 N·m, 61.7 lb, $3,999

500 W Bafang M600 · 120 N·m · 840 Wh · 40–65 miles · 20 MPH · 61.7 lb · 300 lb payload · $3,999 · verified September 22, 2026

Quick Answer — The Eunorau URUS 2.0 is a $3,999 full-suspension electric mountain bike: a 500 W Bafang M600 mid-drive rated at 120 N·m, RockShox at both ends, 61.7 lb. Eunorau publishes a 20 mph top speed and badges the same bike Class 3 — and which one you own decides where you may ride it.

That last sentence is the whole reason this Eunorau URUS review exists. Both figures come from Eunorau's own page. Everything else about the URUS 2.0 is a good trail bike's specification read off a page.

The class question is the one that can cost you the ride you bought it for. We searched for a dedicated review of this machine on September 22, 2026 and found the maker's page, a line of retailer listings and no editorial review at all.

How we verified this Eunorau URUS review

Every figure here was read from a primary document and recomputed, never repeated. Eunorau publishes the URUS 2.0 across two separate surfaces — a product feed and a rendered product page — and this review reads both, plus our own listing, on September 22, 2026.

Where they disagree, the page says which surface is being quoted. Statutes are quoted from the state's own code, never from a summary of it. The arithmetic — watt-hours per mile, payload headroom, gear ratios — is derived here from Eunorau's published numbers and shown so you can check it.

This is a specification-verified review: every claim traces to a published figure, a statute or a document we opened. We sell this bike, so read the red flags as carefully as the green.

What $3,999 buys

Read from Eunorau's product page for the URUS 2.0 on September 22, 2026, and cross-read against its product feed the same day.

The M600, and what 120 N·m actually does

The M600 sits at the cranks. Its torque goes through the gears you are already using.

A mid-drive motor drives the chainring instead of a wheel, which means it uses the same eleven gears you do. The whole argument for a mid-drive on a climb follows from it: in the bottom gear, the motor's torque is multiplied by the same ratio your legs get.

The numbers Eunorau publishes let you see how much. The drivetrain is a 32T chainring against an 11–42T cassette, so the lowest gear is a ratio of 0.76 to 1 (32 ÷ 42) and the highest is 2.91 to 1 (32 ÷ 11).

In that bottom gear the rear wheel turns roughly three-quarters of a turn for every full crank revolution, and the motor's 120 N·m works through that reduction rather than against it. A hub motor on the same hill has one gear, whatever the rider is in.

The 11–42T cassette. Against the 32T chainring that is a 0.76:1 bottom gear — the ratio the motor's torque is multiplied through on a climb.

The M600 is also a torque-sensing unit: Eunorau's page describes assistance "perfectly tailored to the pressure of the pedals". In practice that is the difference between assistance that arrives when you push and assistance that arrives a beat after you start pedaling.

What is not published: Eunorau states 500 W and 120 N·m but no peak output figure and no motor certification number. If the peak matters to you, ask us and we will put the question to Eunorau in writing instead of estimating it for you.

RockShox at both ends — and the specification the internet still gets wrong

RockShox Psylo, 150 mm of travel. The wordmark is legible on Eunorau's own photograph of the bike.

This is the part worth reading twice, because if you research this bike anywhere else you will probably be told something false about what Eunorau actually fits.

Eunorau's current page for the URUS 2.0 publishes a RockShox Psylo 27.5" fork with 150 mm of travel, a tapered steerer and a 15 × 110 mm Boost thru-axle, paired with a RockShox Deluxe Select+ RL rear shock in a 190 × 45 mm configuration with adjustable rebound and lockout. The fork's wordmark is readable in Eunorau's own product photography.

Ask an AI assistant about this bike today and you will likely be told it has an X-Fusion fork with 160 mm of travel instead of what Eunorau publishes. We ran that question on September 22, 2026 and got exactly that answer, sourced entirely from retailer listings.

Those listings are describing an earlier version of the URUS. The bike Eunorau sells now is on RockShox at both ends, and its published travel figure is 150 mm.

Why it matters to you: a fork is expensive to change your mind about after delivery, and "RockShox Psylo with a Boost thru-axle" and "X-Fusion" are different purchases with different service parts. If a retailer's page tells you one and Eunorau's page tells you the other, the maker's current page is the one to buy from.

Front wheel: a Maxxis Minion DHF in 27.5 × 2.8", the tread Eunorau pairs with a Minion DHR II at the back.

840 watt-hours, and what 40 to 65 miles is really saying

The pack is 48 V × 17.5 Ah, which is 840 watt-hours — a figure Eunorau does not print but which its own two numbers give you directly.

Set that against the published range of 40 to 65 miles and you get the efficiency band the range claim assumes:

Both numbers are ours, derived here from 840 ÷ 65 and 840 ÷ 40 against Eunorau's own pack and range figures.

That band is the useful part. Twelve-point-nine watt-hours per mile is a low-assist number on smooth ground, well inside the federal motor-only test, — the sort of figure you reach in level 1 on a fire road, pedaling properly. Twenty-one is what climbing costs.

Neither figure is a lie. They are the two ends of a range that depends almost entirely on which of those two rides you are doing. On a full-suspension trail bike on the 27.5 × 2.8" knobbly tires Eunorau fits, plan around the lower end of the mileage rather than the upper.

The pack is removable, with a lock, and charges on a 48 V 2 A charger. At 2 A a 17.5 Ah pack takes roughly nine hours from empty on the charger's own rating; Eunorau's feed states 5–7 hours, which implies the pack is not being charged from fully flat.

61.7 pounds, and the 300 pounds it will carry

Eunorau publishes 61.7 lb / 28 kg for the 17" frame and a 300 lb / 136 kg maximum payload.

Subtract one from the other and the number you actually need appears: 238 pounds for rider, clothing, pack, tools and water. Weigh yourself against 238, rather than against the 300.

Two honest notes on that weight. First, 61.7 lb is the published figure for the 17" frame; the 19" frame's weight cell on Eunorau's geometry table is empty, so the larger bike's weight is not published and we are not going to invent it. Second, 61.7 lb is a number you will meet every time you lift this bike onto a rack or up a step, and no amount of motor changes that.

Sizing: two frames, and the number to size from

Eunorau publishes a recommended rider height of 5'3" to 6'4" (160–193 cm) across two frames, URUS-17 and URUS-19.

Size from the millimeters. Reach and stack are the two rows that decide whether a bike fits: reach is how far you are stretched to the bars, stack is how tall the front end sits. Between the 17 and the 19 the reach grows 20 mm and the stack grows 49 mm, so the larger frame is noticeably taller at the front rather than merely longer.

If you are in the middle of that height range, the reach and stack rows above are the two to read. There is a frame-size ask further down this page if you want a second pair of eyes on it.

The Mercer fit test

The Mercers are our editorial cast — a fixed family of seven we hold every bike against, so the same questions get asked every time. Every verdict below reads a number Eunorau publishes. Meet the Mercers. Every verdict below is read from a published number: Eunorau's rider-height range, its payload ceiling, its frame geometry and its weight.

The sharpest contrast in that table is Jack and Maya. Jack gets the bike it was designed for: a 6'1" rider on a 150 mm-travel trail machine with a low climbing gear. Maya fits it on paper by exactly the same measurement and should still buy something else, because a 61.7 lb bike with no lights in the box is not a commuter. Fit is not only whether the frame is your size.

Has it been recalled?

No. We queried the Consumer Product Safety Commission's own recall database on September 22, 2026 across a 621-record corpus built from bicycle, e-bike, battery and scooter terms, searching every field rather than titles alone. Eunorau appears in no recall record.

The screen was validated before its result was believed: control brands returned their known recalls in the same run (Ancheer 1, Specialized 49, Trek 34), so a null result for Eunorau is a measured absence rather than a query that failed to fire.

Is it UL certified?

Eunorau's product page carries a badge reading "UL CERTIFIED: Yes".

What that badge does not do is name a standard, a laboratory or a file number. Those three are what make a certification checkable: with them you can look the certificate up, and without them there is nothing to look up at all. None of the three appears on the page.

It matters because the agency says it does. The Consumer Product Safety Commission reminds consumers "to use micromobility devices and batteries that have been designed, manufactured, and certified for compliance with the applicable voluntary safety standards" — and compliance you cannot trace to a named standard is not something you can check.

What to do about it: if your apartment building, insurer or city requires a UL-listed battery, ask us before you order and we will request the certificate and the standard number from Eunorau in writing. We would rather get you the document than have you discover the gap after delivery.

Class 3, 20 mph and a throttle: what Eunorau publishes

This is the question the page was written to answer.

On one screen, Eunorau's product page for the URUS 2.0 publishes all three of these, and the third of them is also in its product feed:

• a badge reading "CLASS · Class 3 · Speed limited · Unlockable"
• a specification table reading "MAXIMUM SPEED — 20 MPH / 32 KPH"
• a thumb throttle in the controls list

In the states that run the three-class system, those three things do not describe the same vehicle. California wrote the version of that system other states have drawn on, and it is worth quoting exactly. California Vehicle Code § 312.5, read September 22, 2026:

A "class 3 electric bicycle," or "speed pedal-assisted electric bicycle," is a bicycle equipped with a motor that provides assistance only when the rider is pedaling, that is not capable of exclusively propelling the bicycle, except as provided in paragraph (4), and that ceases to provide assistance when the bicycle reaches the speed of 28 miles per hour, and equipped with a speedometer.

Two limbs of that definition decide it. A class 3 bike assists only when the rider is pedaling, and its motor is not capable of exclusively propelling the bicycle. A thumb throttle is a motor that propels the bicycle exclusively.

The same section defines the category a throttle machine does fit. Under § 312.5(a)(2), a class 2 electric bicycle is one "equipped with a motor that may be used exclusively to propel the bicycle, and that is not capable of providing assistance when the bicycle reaches the speed of 20 miles per hour."

So in a state using that text, a 20 mph machine with a throttle is a class 2 electric bicycle, and the "Class 3" on the badge is not the class the statute would assign it.

It is not a California quirk, and it is not only state law. The Bureau of Land Management carries the same definition in federal regulation: under 43 CFR 8340.0-5(j) a class 1 and a class 3 electric bicycle each have a motor "that provides assistance only when the rider is pedaling", while a class 2 is the one whose motor "may be used exclusively to propel the bicycle" and stops assisting at 20 mph.

Colorado writes the same limb into C.R.S. 42-1-102(28.5): a class 1 and a class 3 electrical assisted bicycle each have a motor "that provides assistance only when the rider is pedaling", and the class that "provides assistance regardless of whether the rider is pedaling" is class 2, capped at 20 mph. Two states, written independently, put the throttle in the same place.

Three authorities, each retrieved separately, agreeing on the same limb.

Where the 28 comes from. Eunorau's product feed — the data file behind the page, which retailers republish — carries "MAX SPEED: 28 mph / 45 km/h". That figure does not appear anywhere on the rendered page a buyer reads; we checked the page in a browser on September 22, 2026 and found no "28 mph" in its 11,274 characters of visible text.

But it is the figure that has spread. Third-party listings title this bike "Top Speed 28mph", and when we asked an AI assistant what class the URUS is, it reasoned from 28 mph to "Class 3" and never saw the maker's own 20.

On the federal side, 15 U.S.C. § 2085(b) defines a "low-speed electric bicycle" as one with fully operable pedals and a motor of less than 750 watts, "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." That section also makes a low-speed electric bicycle subject to the federal bicycle regulation at 16 CFR part 1512.

The 500 W motor is comfortably inside the wattage limb. The speed limb asks about motor-only speed, and Eunorau publishes one speed figure without saying whether 20 mph is the throttle-only number or the assisted one. The question has a real answer, and it is the second thing we will get in writing for you.

What to do with all of this. Do not buy this bike on the badge, because the badge is the one thing on that page the statutes do not agree with. Ask us which figure ships on the unit you are ordering, and we will get Eunorau's answer in writing before your money moves. It is a five-minute question for us and an expensive one for you to answer after delivery.

Where you can actually ride it

This is the part the class badge decides, and it is why the badge matters more on a mountain bike than on anything else we sell.

Access to natural-surface trails in the United States is set by the land manager, not by the state vehicle code — the Forest Service district, the BLM field office, the state park system or the county open-space department that owns the trail.

On National Forest land the position is written down. The Forest Service issued its final e-bike directives on March 31, 2022, and its own notice of them (87 FR 41278, July 12, 2022) records what they do.

They "add a definition of e-bikes as a class of motor vehicle, including separate definitions for Class 1, 2 and 3 e-bikes", and they "provide for managing all classes of e-bikes as motor vehicles and require local-level decision-making and environmental analysis to allow use of e-bikes on non-motorized trails."

Read that twice, because it is the whole answer. Every class of e-bike — including a Class 1 — is a motor vehicle on National Forest System land, and a non-motorized trail has to be re-designated before any of them may ride it. Where districts have opened trails, the permission has commonly been written for Class 1 machines.

A throttle is what puts this bike outside that Class 1 permission where one exists. It is not a comment on the URUS: it is true of every throttle-equipped e-mountain bike sold in America, which is a large share of them.

Three owners, three different documents. Not one of them is the bike's spec sheet.

So before you buy a trail bike, check the trail. Look up the specific system you ride on its own manager's website, and read the class language, not the word "e-bike".

What getting it wrong costs. Once a Ranger District has published its motor vehicle use map, 36 CFR 261.13 prohibits operating a motor vehicle on National Forest System land "other than in accordance with those designations".

36 CFR 261.1b sets the punishment for breaking any prohibition in that part at "imprisonment of not more than six months or a fine in accordance with the applicable provisions of 18 U.S.C. 3571 or both". That is why the first line of the checklist below is the map and not the machine.

If the answer is Class 1 only, the URUS is a bike for fire roads, OHV routes, gravel and your own property, and it is a very good one for those. If it is a singletrack machine you need and your local network is Class 1, say so when you email us and we will point you at something that fits the rule you actually ride under — including when that means a bike we make less money on.

Buying it from us

Why buy the URUS 2.0 from Redtail

You pay Eunorau's own number. Our $3,999 is the figure on the maker's page when we read it on September 22, 2026, so ordering from a US store costs you nothing over ordering direct.

What it adds starts after the carton arrives. Shipping inside the lower 48 is free, and a damaged delivery is a claim we file rather than a form you fill in.

A warranty repair is one we coordinate with Eunorau instead of handing you a factory contact overseas. On a mid-drive that is worth more than it sounds: an M600 wanting a sensor or firmware diagnosis is not a parcel you want to be posting across an ocean.

Cloud White, the colorway orderable in both frame sizes on September 22, 2026 — the listing shows both.

The same bike from the other side. Both 17" and 19" are in stock in this colorway.

Navy — unavailable in both frame sizes as we publish. Tell us if you want it and we will let you know when it returns.

Amethyst, the third colorway Eunorau lists. Also unavailable in both sizes today.

Change of mind is separate from all of the above: unopened and in its factory-sealed packaging, requested within 72 hours of delivery, with a 15% restocking fee and return shipping — which is why we would rather answer your fit and class questions before you order than after.

Green flags / Red flags

Green flags

• RockShox at both ends — a Psylo fork with 150 mm of travel and a Deluxe Select+ RL rear shock, at a price where own-brand suspension is common.
• A genuine mid-drive with a 0.76:1 bottom gear, so the motor's 120 N·m is multiplied through the gears on a climb instead of fighting the hill in one ratio.
• Maxxis Minion DHF front and DHR II rear, the tread pairing trail bikes at much higher prices ship with.
• A 300 lb payload, leaving 238 lb for rider and load once the bike's own 61.7 lb is subtracted.
• A removable, locking battery, so it charges away from the bike and off the floor it is parked on.
• A remote dropper post in the box at $3,999, and not as an upgrade.
• Price parity with the maker — $3,999 on both sides, no compare-at, so there is no invented saving on this page.

Red flags

The second column is about fit: who this bike is wrong for, and what to read instead.

• Wrong if you ride non-motorized singletrack. The throttle puts it outside the Class 1 permission that trail systems usually write. If that is your riding, read our electric mountain bike guide and we will match you to something your land manager allows.
• Wrong if you want the same suspension for less. The Eunorau SPECTER-S is the other full-suspension machine in this family and sits below the URUS on price; read that review next if the $3,999 is the sticking point.
• Wrong as a commuter, at 61.7 lb with no lights in the box. If that is the ride you actually do, read our commuter picks instead.
• Wrong if you needed 65 miles every time. That is the optimistic end of a 40-65 mile band, and climbing spends the 840 Wh pack at closer to 21 watt-hours per mile. Plan on the 40 — or tell us the ride you actually do and we will work the watt-hours against it with you before you order.
• Wrong if you wanted Amethyst or Navy today — both read unavailable in both frame sizes on September 22, 2026. Tell us which you want and we will let you know when it lands.
• Wrong if you need lights in the box. Eunorau lists front and rear lights as not included, so budget for them before the first ride after dark — email us and we will tell you what fits this fork and rack mount.
• Wrong if you need a settled top-speed answer before you pay. Eunorau's page publishes 20 mph and badges the bike Class 3; we will get the shipped figure in writing from Eunorau before your money moves.

Buy it if / Buy something else if

Buy it if you ride fire roads, gravel, OHV-legal routes or your own land; you want a mid-drive that climbs in gears instead of on brute hub torque; you are between 5'3" and 6'4"; and you are happy on Cloud White, which is the colorway in stock today.

At $3,999 you are buying RockShox suspension at both ends, a Bafang M600 and Maxxis Minions — and the installment figure on our listing is $360.94 a month over 12 months at 15% APR, subject to an eligibility check.

Buy something else if your riding is non-motorized singletrack and your local land manager writes Class 1 only — the Eunorau Defender is the full-suspension bike in this range we would point you at first for softer ground.

Buy something else, too, if you need a commuter — 61.7 lb and no lights are the wrong two numbers for that job; or if the colorway matters more than the timing, in which case tell us and we will let you know when Amethyst or Navy is back.

Before you buy: the checklist

Eight things to settle before you spend $3,999. The first two decide whether this is the right bike for you at all; the rest take a few minutes each and are easier to do now than after the carton arrives.

1. Look up your trail system's own e-bike rule and read the class language rather than the word "e-bike".
2. Email us the class question. We will get Eunorau's written answer on the shipped top speed before you pay.
3. Ask for the UL certificate and standard number if your building, insurer or city rule requires one.
4. Measure your height and inseam and send them to us against the reach and stack table above.
5. Check Cloud White is the colorway you want, because it is the one orderable today.
6. Budget for lights, which are not in the box.
7. Weigh your load against 238 lb, the payload left after the bike's own 61.7.
8. Plan your range around the 40-mile end rather than the 65 if you are climbing.

Frequently asked questions

How fast does the Eunorau URUS 2.0 go?

Eunorau's product page publishes a maximum speed of 20 MPH / 32 KPH. Its product feed — the data file retailers republish — carries 28 mph instead, and that is where the "28 mph" you see on third-party listings comes from. The two disagree, the rendered page is the one Eunorau shows buyers, and we will get the shipped figure in writing for you before you order.

Is the Eunorau URUS 2.0 a Class 3 electric bike?

Eunorau badges it Class 3. Under California Vehicle Code § 312.5 — the version of the three-class system other states have drawn on — a class 3 electric bicycle assists "only when the rider is pedaling" and is "not capable of exclusively propelling the bicycle." The URUS has a thumb throttle, which is a motor that can propel it exclusively, and the same section puts a throttle machine limited to 20 mph in class 2.

Can I ride it on mountain bike trails?

That depends on the land manager, not the state. On National Forest land the Forest Service's final directives manage every class of e-bike as a motor vehicle, and opening a non-motorized trail to any of them takes a local decision.

Where districts have done it, the permission has commonly been written for Class 1, and a throttle puts the URUS outside that. On fire roads, gravel, OHV-legal routes and private land it is a strong fit. Check your specific trail system's own rule before you buy.

What motor does the Eunorau URUS 2.0 use?

A 48 V 500 W Bafang M600 mid-drive, which Eunorau rates at up to 120 N·m of torque. It drives the chainring rather than a wheel hub, so its torque passes through the 11-speed drivetrain.

How far does the URUS 2.0 go on a charge?

Eunorau publishes 40 to 65 miles. The pack is 48 V × 17.5 Ah, which is 840 watt-hours, so that range assumes between 12.9 and 21.0 watt-hours per mile — figures we derived from Eunorau's own numbers. On knobbly 2.8" tires with climbing involved, plan around the lower end.

How much does the Eunorau URUS 2.0 weigh?

61.7 lb / 28 kg, which is the published figure for the 17" frame. Eunorau's geometry table leaves the 19" frame's weight cell empty, so the larger bike's weight is not published.

What size rider does it fit?

Eunorau publishes a recommended rider height of 5'3" to 6'4" (160–193 cm) across two frames. The 17" has 424 mm of reach and 420 mm of stack; the 19" has 444 mm and 469 mm. Send us your height and inseam and we will read them against that table with you.

What suspension does it have?

A RockShox Psylo 27.5" fork with 150 mm of travel and a RockShox Deluxe Select+ RL rear shock, 190 × 45 mm, with adjustable rebound and lockout. If you find a listing claiming an X-Fusion fork with 160 mm, that is an earlier version of this bike.

Does it come with lights?

No. Eunorau's specification lists front and rear lights as not included. Budget for them before your first ride after dark.

Has the Eunorau URUS 2.0 been recalled?

No. We searched the CPSC's own recall database across a 621-record corpus on September 22, 2026, every field and not titles alone, and Eunorau appears in no recall record. Control brands returned their known recalls in the same run, so the null result is measured, and not a failed query.

Is the battery UL certified?

Eunorau's page carries a "UL CERTIFIED: Yes" badge and names no standard, laboratory or file number. If you need a certificate — for an apartment building, an insurer or a city rule — ask us and we will request it and the standard number from Eunorau in writing.

What is the difference between the URUS 2.0 and the older URUS?

The current bike is on RockShox at both ends with 150 mm of fork travel. Listings describing an X-Fusion fork with 160 mm of travel are describing the earlier version. If you are comparing prices across retailers, check the fork line before you compare anything else.

Which colorway can I actually order?

Cloud White, in both 17" and 19" — 2 of 6 variants — read from our own store on September 22, 2026. Amethyst and Navy are unavailable in both sizes as we publish. Tell us if you want one of those and we will let you know when it returns.

Limitations of this review

Seven things this review cannot settle, set out so you can weigh them yourself rather than take the verdict on trust.

1. We sell this bike. Read the red flags as carefully as the green.
2. This is a specification-verified review. Every figure comes from Eunorau's published documents, a statute, our own store record or arithmetic shown on this page.
3. The UL certification could not be verified to a standard. Eunorau's page asserts "UL CERTIFIED: Yes" and publishes no standard, laboratory or file number, so we cannot tell you which standard the certification is to. We re-read every Eunorau product page we have reviewed on September 22, 2026 — 13 pages, all of which returned — and none names a standard. We have asked for the certificate instead of assuming its scope.
4. The 19" frame's weight is not published. The 61.7 lb figure on this page is the 17" frame's.
5. The top-speed question is open, and this page publishes both figures instead of choosing one. We are seeking Eunorau's written answer.
6. Trail access is local. Nothing on this page substitutes for reading your own land manager's rule, which can change and which differs between adjacent systems.
7. Stock and price were read on September 22, 2026 and both move.

The bottom line

At $3,999 the URUS 2.0 is a lot of suspension, a real mid-drive and the right tires. RockShox at both ends, a Bafang M600 geared to 0.76:1 at the bottom, Maxxis Minion DHF and DHR II, a remote dropper in the box, 300 lb of payload and a removable locking battery.

On fire roads, gravel, OHV-legal routes and private land that is a strong bike for the money. The installment figure our own listing shows — $360.94 a month over 12 months at 15% APR, subject to an eligibility check — is how most people will pay for it.

The thing to settle before you buy is not the specification. It is the class. Eunorau badges this bike Class 3, publishes 20 mph, and fits a throttle, and those three facts point in different directions under the statute quoted above. On a mountain bike that question decides which trails you may ride, which is the whole purchase.

So: email us before you order. We will get Eunorau's written answer on the shipped top speed and the UL certificate, and we will tell you straight if your local trail rule means you should buy a different bike — including one we make less money on.

Source register

Every document this review rests on, with the claims each one carries. All seven are T1 — the party that created the record, rather than anyone reporting on it.

Expiry conditions

This page should be re-read if any of the following happens: Eunorau changes the specification, the class badge or the top-speed figure on its product page; Eunorau answers our written question on the shipped speed or the UL certificate; the price or the buyable colorways change on our store; or a recall is published naming Eunorau.
