Eunorau META275 2.0 Review 2026: 68.4 lb, $1,699

48V 500W hub · 55 N·m · torque sensor · 720 Wh · 20 MPH · 68.4 lb · 27.5" × 2.6" tires · $1,699 · verified September 9, 2026

Quick Answer — The Eunorau META275 2.0 is a $1,699 Class 2 commuter: 500 watts, a torque sensor, 27.5-inch wheels on a 2.6-inch tire, 20 MPH. Every third-party "Meta275 review" online (Electrek, RideReview, Electrified Reviews) describes a different, earlier configuration matching neither of Eunorau's two current listings.

Its own published fit range, 5'6" to 6'1", is the narrowest of any META we stock — seven inches, against 11 or 12 on its siblings. Buy it when you sit in that window and want the family's largest wheel; check the family table first if you are near either end of it.

Every figure above is Eunorau's own published specification, read on both of the company's surfaces the same day and cross-checked against three sibling spec tables and the maker's own current listing for the META275 1.0.

How we verified this Eunorau META275 2.0 review

Verification basis: every specification on this page was confirmed at the manufacturer and recomputed. Eunorau's rendered product page and its storefront product feed were both retrieved on September 9, 2026 and compared row by row.

The maker's separate, current listing for the META275 1.0 was retrieved the same day for the version comparison below — not a footnote.

The family arithmetic is ours and it is shown. Four members of the META line publish the same 286 lb payload rating and four different fit ranges; the fit-corridor arithmetic is recomputed fresh from all four spec tables the same week, and none of it carries over from an earlier page.

Price, colorways and inventory come from our own store listing through the Shopify Admin API on the same date. The two limbs of the federal definition are quoted from the statute itself, and this bike's own published wattage and speed were screened against all 51 US jurisdictions' own statutory definitions.

The recall and safety-warning searches ran against the Consumer Product Safety Commission's own complete listings and were control-tested against a brand carrying two known open CPSC warnings before Eunorau's silence was believed.

A search for third-party coverage of "the Meta275" turns up real reviews of a different bike. Electrek reviewed it in February 2023, RideReview carries a listing, and Electrified Reviews covered the 2022 model. Every one of those describes a 67 lb bike with a 48V 13Ah (624 Wh) battery at $1,799, figures that match neither of Eunorau's two current META275 listings exactly. What that means for a shopper is the subject of the next section.

Written by Milad Ghobadibeygvand, BScN (Western University, 2014). Corrections: support@redtailebikes.com. We sell this bike, so read the fit warnings as carefully as the specifications.

The 1.0 and the 2.0 are not the same bike — and neither matches the reviews

Eunorau currently sells two META275 configurations side by side, and the naming implies the 2.0 is a straightforward upgrade over the 1.0. Reading both of the maker's own current product pages the same day says otherwise on the one spec a buyer would expect to move in one direction.

Two hundred fifty watts of federal headroom, on the number that does NOT change between the two META275 configurations.

The 1.0's tire is published two ways on its own page. Eunorau's icon banner and Components table for the 1.0 both read 27.5" × 2.6"; its description block reads 27.5 × 3.0. Electrek's 2023 review of that model records 2.6 inches. Both published figures are in the table above; our META275 1.0 review sets all three surfaces side by side.

Where the two bikes genuinely part company is torque and gears. The 1.0 publishes 65 N·m and a Shimano nine-speed; the 2.0 publishes 55 N·m and a seven-speed. The 2.0 answers back with 96 more watt-hours, a step-through frame and EUNORAU GO app support on its display row.

And the third-party reviews match neither current listing. Electrek's 67 lb, 624 Wh, $1,799 Meta275 shares its 2.6-inch tire with today's 2.0 but its 13Ah battery size with today's 1.0, and its weight and price appear on neither current page. A 2025-dated brand roundup we found while harvesting demand for this page names a third figure set again, $1,979 and a 624 Wh battery. We are not attempting to reconstruct this model's history here; we are reporting what three independently retrieved sources say against what Eunorau's own current pages say, on the same day.

Seven inches: the narrowest fit window in the family

Eunorau publishes a rider-height range of 5'6" to 6'1" for the META275 2.0 — a seven-inch corridor, and the same corridor the META275 1.0 publishes. Both 27.5-inch bikes are narrower here than any smaller-wheeled META we stock.

Seven inches against eleven or twelve on every sibling. The 275 2.0 is pickier about who it fits than any other META.

Two things happen at once, and only one of them is obvious. The floor rises: 5'6" is the highest floor in the family, two inches above the META26's and five above the META20's, which is what a taller-wheel bike would predict. But the ceiling does not rise with it: at 6'1", both 27.5-inch bikes tie the smallest-wheeled META20 for the lowest ceiling in the family, a full two inches under the META26's 6'3". A bigger wheel bought this bike a higher floor and nothing at the top.

What that means for a buyer near either edge. A rider at 5'5" clears every other META in this family and misses this one by an inch. A rider at 6'2" clears the META24 and the META26 and misses this one too. The seven-inch window is real, and it is not simply "for taller riders," which is the assumption the wheel size invites.

The same seven-inch window applies regardless of colorway — Steel Blue included.

Where you may ride it: 51 jurisdictions, screened

Most of what we sell is not an electric bicycle in the federal sense. This one is, and on our shelf that is worth leading with.

15 U.S.C. § 2085(b) defines a low-speed electric bicycle as:

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.

16 CFR § 1512.2(a)(2) repeats that wording inside the Consumer Product Safety Commission's bicycle regulations.

The motor is 500 watts, which leaves 250 watts of room under the federal ceiling. On the speed limb, Eunorau publishes a maximum of exactly 20 MPH. A published figure sitting on the boundary is met at the boundary, not rounded under it.

Eunorau's own specification banner for this model prints "CLASS: Class 2." A thumb throttle plus a 20 MPH cap is the model-legislation definition of Class 2, the least restricted of the three tiers in most states that use the framework.

We screened the published figures (500 W, 20 MPH, thumb throttle) against all 51 US jurisdictions' own statutory definitions, the same method and the same statutory inputs already screened for the META20, because both bikes publish the identical wattage and speed:

Zero jurisdictions place these published figures outside their definition. What that means for you: this is a bike you buy without first solving a legal question. Local path and trail rules still vary, and our state e-bike law pages work through 33 states from the statutes.

Fifty miles on the battery that comes in the box

The battery is 48 V 15 Ah on both of Eunorau's surfaces — 720 watt-hours.

Eunorau advertises up to 100 miles, printing the basis beside the claim: "48V 15Ah Battery+ Second Battery 15Ah." The second pack is an optional accessory. So the 100-mile figure rests on 1,440 Wh while the bike ships with 720 Wh.

Apply 14.4 Wh/mi to the 720 Wh pack that ships and you get 50.0 miles. This is the identical battery, controller and range basis the META20 and the META26 publish, because all three share the same pack — the arithmetic is re-derived fresh here rather than assumed to carry over.

Both of Eunorau's spec sheets, read side by side

We retrieved both of Eunorau's own surfaces for this bike on the same day, the rendered product page and the storefront product feed, and compared every labelled row.

Every load-bearing figure agrees between the two surfaces. Voltage, amp-hours, watts, torque, top speed, weight, payload, rider height and tire size read the same on both. One labelling artifact appears on both surfaces identically, so it is not a surfaces-disagree finding: the specification block's own header text reads "The City Model META275 1.0 E-Bike Specifications," even though the page it sits on is titled and priced as the 2.0. Every figure inside that block (the 68.4 lb weight, the 5'6"–6'1" fit range, the 720 Wh battery) matches the 2.0's own listing elsewhere on the same page and matches our own store's record. We read this as a header-text copy-paste error inside Eunorau's own template. It does nothing to the figures inside that block, which line up with the 2.0 everywhere else we checked them.

One additional row, Box Dimensions (159.5 L × 34 W × 89.5 H cm), appears in the specification block: the shipping carton, a different measurement from the bike itself, relevant to freight planning rather than fit or storage.

The geometry diagram borrows another bike's name

Unlike the META20, which publishes a numeric geometry table (wheelbase, total length), Eunorau publishes no numeric geometry figures for the META275 2.0. The page's Geometry section carries a single diagram image instead.

That image file is shared, byte-for-byte, with the META24's own product page — the filename is literally meta24-275.jpg, and its alt text reads "Moped style E-bike Eunorau Escape Geometry." "Escape" is not a model Eunorau lists in this family at all.

We treat this the same way we treated the specification-block header above: a labelling defect in the maker's own asset library. This model's actual frame dimensions are simply not published in numeric form, and we report that gap plainly rather than guess at it.

Brakes, gears and the parts your hands are on

The 27.5 by 2.6 inch Chaoyang tire on a black alloy rim, with the front suspension fork and the frame's motor-cutoff wiring visible behind the hub.

Braking. Hydraulic disc brakes on 180 mm rotors, front and rear, with motor-cutoff switches in both levers so assistance stops the instant you pull. 16 CFR § 1512.5(b)(1) sets the federal stopping-distance requirement for bicycles, and hydraulic discs on a 68.4 lb, 20 MPH machine are proportionate hardware for it.

Shimano's 7-speed cassette and derailleur behind the 27.5 by 2.6 inch rear tire — the tire the maker's own current 1.0 listing runs one size wider (3.0 inches) on the same wheel.

Shifting. A SHIMANO ASLM3157RC 7-speed shifter and a Shimano derailleur 7-speed freewheel, turned by a 42T chain-wheel crank on a 170 mm forged aluminum crank arm, the same 42T ring the META24 and META26 use, six teeth smaller than the META20's 48T.

The display and the tire. A BC182 LCD with Bluetooth and EUNORAU GO app support, the display fitted across the whole family. The tire is 27.5" × 2.6" Chaoyang, narrower than the 3.0-inch tire every other current META in this family runs.

The tire that runs narrower than its own family, and narrower than the current META275 1.0 it shares a name with.

A fixed-angle cockpit — Eunorau's spec sheet does not describe a telescoping stem on this model the way it does on the META20.

The cockpit. A thumb throttle, hydraulic brake levers and an LED headlight. Eunorau's specification for this model does not describe the quick-release telescoping stem the META20's page calls out; we did not find that feature named for the META275 2.0 on either surface, so we report it as absent from the published record rather than assuming it is fitted.

Rack and full-coverage fender fitted from the factory, with the "META275" decal running down the tube, the correct decal for this model, confirmed against a photo-assignment defect on our own product listing (see Limitations).

The parts that make it a commuter. A rear rack and a full-coverage fender are fitted as standard, along with front and rear LED lighting and an EUNORAU C7 comfort saddle.

Charging. A US-standard 2.0 A smart charger on a 48V 20A controller, with a published 5 to 7 hour charge time for the 720 Wh pack.

Buying it from us

Every row here points at a document, because a trust module that only asserts things is not a trust module.

A photo-assignment defect on our own store, corrected here. The manufacturer's own photography for this model is correct and distinct from every sibling, verified by SHA-256 against the META24's files. Our own listing photos for this handle had been mis-assigned to the META24's photo set, a defect this project's own tracking caught on 2026-09-08. Every photograph on this page is the manufacturer's own META275-decal frame, re-verified before use.

Deep Crimson, Steel Blue, Alpine White, Pastel Pink and Dark Charcoal — 25 of each in our warehouse as this publishes.

Which META suits your body: 20, 24, 26 or 275

Eunorau builds the META as a family and buyers shop it as one. Four sit on our shelf at the same $1,699, so the money is not part of this decision.

This bike ties the META26 for heaviest in the family and ties the META20 for the lowest fit ceiling — the two comparisons a shopper would least expect from "the biggest-wheeled META." Its actual advantage is rolling on the largest wheel diameter of the four, which a taller rider inside its own window will feel most on rougher pavement, not a fit or weight advantage over its siblings.

If you are outside 5'6"–6'1", three siblings are worth a look before this one: the META26 for a higher ceiling, the META20 or META24 for a lower floor.

The Mercer fit test

Seven riders, one bike. The Mercers and Kowalskis are the editorial cast we hold every review against, archetypes with fixed bodies and fixed lives, never testers. Every verdict below reads a published number or an age rule, and nothing else.

Good for Maya, wrong for Ruth, one inch apart, and it is entirely about fit rather than the bike itself. Ruth Kowalski is inside every other META's published range and outside this one's by a single inch. That is the seven-inch corridor from earlier in this review, made concrete: the narrowest fit window in the family excludes real riders that its siblings would welcome.

Has it been recalled?

No. Screened September 9, 2026 against the Consumer Product Safety Commission's own data:

• Federal recalls: the Commission's recall service returned no record naming Eunorau as a whole word, across four independently validated query fields.
• Product safety warnings: Eunorau appears in 0 of the 359 warnings in CPSC's complete published warning listing, matched on whole words.

The instrument was control-tested in the same run before either silence was believed. The warning listing was searched for a brand carrying two known open CPSC warnings and returned both; the recall service's query fields were each probed with a positive and a negative control before use. A search that cannot find what is certainly there cannot be trusted when it finds nothing.

This is a screened record on the date shown rather than a permanent state. Check CPSC yourself before buying anything from anyone, and register the bike so a future notice reaches you.

Is it UL certified?

Eunorau publishes a UL claim on this model's own page and a testing announcement covering the range.

The META275 2.0 product page carries a UL CERTIFIED: Yes badge in its own specification banner. Separately, in the company's own words, dated March 5, 2023: "all of our ebikes have passed the UL 2849 testing", and "Our ebike batteries have also passed the UL 2271 tests."

UL 2849 covers the whole electrical system; UL 2271 covers the battery pack alone. Those two standards are the ones New York City wrote into law in 2023, barring the sale of e-bikes and batteries not certified to them.

If your building, your insurer or a local ordinance wants a certificate number for this model, ask us and we will request it from Eunorau before you pay.

Whatever the paperwork says, charge any pack on a hard surface, away from your exit route, on the charger it shipped with.

Green flags / Red flags

Green flags

• The family's largest wheel diameter, 27.5 inches, for a rider inside its own fit window on rougher pavement.
• Legally an electric bicycle at 500 W, with 250 W of federal headroom and zero of 51 jurisdictions placing it outside their definition.
• A torque sensor at $1,699, with a rack, full fenders and lights fitted as standard.
• Every load-bearing spec agrees across both of Eunorau's own surfaces, checked the same day.
• Zero federal recalls and zero CPSC safety warnings, on a screen control-tested in the same run.
• A 10-year frame warranty behind a US corporate entity.
• Five colorways, all five in stock, 125 units as this publishes.

Red flags, meaning who this bike is wrong for

• Wrong if you are outside 5'6"–6'1". This is the narrowest window in the family by four to five inches, and the bike does not reach as high as the META26 despite its bigger wheel.
• Wrong if you found a "Meta275 review" online and assumed it described this bike. Every one we found describes a different configuration — a different tire width, battery size or price.
• Wrong if frame geometry decides your purchase. No numeric wheelbase or trail figure is published for this specific model, unlike the META20.
• Wrong if you want to keep pace with traffic. Twenty miles an hour is the cap by design. If speed is the requirement, the Eahora Romeo Pro has it and carries the legal question this bike does not.
• Wrong if your ground is loose. A 2.6-inch city tire and 55 N·m suit pavement and firm gravel; sand, snow and wet clay want the FAT-AWD 3.0 and its motor at each end.
• Wrong if balance at a stop is the problem you are solving. Three wheels answer that; the ONE-TRIKE 2.0 is our 500 W answer at the same price.

Buy it if / Buy something else if

Buy it if you sit inside the 5'6"–6'1" window and want the family's largest wheel for rougher pavement. That combination (the biggest wheel diameter of the four, a torque sensor, and a legally uncomplicated Class 2 rating) is what the META275 2.0 offers, and no third-party review you find searching this bike's name will describe it accurately.

Buy something else if any of that misses. If you are shorter than 5'6" or taller than 6'1", the META20, META24 or META26 each reach further in one direction. If your problem is loose ground, the FAT-AWD 3.0 is the same $1,699 with a motor at each end. If it is speed, read our Eahora Romeo Pro review before you spend anything. If it is balance, the ONE-TRIKE 2.0 puts the same 500 W and 20 MPH on three wheels.

Before you buy: the checklist

1. Measure against 5'6"–6'1" precisely. This window is narrower than any other META's, and an inch either side changes the answer.
2. Add up your loaded weight against 217.6 lb. You, clothes, helmet, lock, bag, rack contents. The bike's 68.4 lb is already subtracted.
3. Decide about the second battery now. One pack is 50.0 miles at the maker's own implied efficiency; two is the 100-mile claim.
4. Check your state's Class 2 rules, especially the minimum age if the rider is a teenager.
5. Ignore any spec you read on a page not titled "META275 2.0." Confirm it here first.
6. Pick a colorway on the product page. All five are in stock today.

Frequently asked questions

How much does the Eunorau META275 2.0 weigh?

68.4 lb, published by Eunorau on both of its surfaces — tied with the META26 for heaviest in the family.

Is the Eunorau META275 2.0 the same bike as the "Meta275" reviewed by Electrek or other sites?

No. Electrek's review, RideReview's listing and Electrified Reviews' coverage describe a 67 lb, 48V 13Ah battery, $1,799 configuration that matches neither of Eunorau's two current META275 listings. Full comparison.

What is the difference between the META275 1.0 and the META275 2.0?

The 1.0 (current price $1,399) runs a wider 27.5" × 3.0" tire and publishes no weight, rider-height or payload figure. The 2.0 (this review, $1,699) runs a narrower 27.5" × 2.6" tire and publishes all three. Full spec comparison.

What height is the Eunorau META275 2.0 for?

5'6" to 6'1", the narrowest published range of any META we stock, at seven inches. Details.

What is the weight limit on the Eunorau META275 2.0?

286 lb total payload capacity. Eunorau does not state whether the bike's own weight counts toward it, so treat the working figure as 217.6 lb for rider plus cargo — 286 minus the bike's own 68.4 lb.

How far does the Eunorau META275 2.0 go on one charge?

The pack it ships with is 720 Wh. Eunorau's 100-mile figure assumes a second 15 Ah battery bought separately, implying 14.4 watt-hours per mile. Apply that to one pack and you get 50.0 miles. Working here.

How fast does the Eunorau META275 2.0 go?

Twenty miles per hour, the Class 2 ceiling in states using the three-class system. Eunorau's own specification banner prints "CLASS: Class 2."

Is the Eunorau META275 2.0 street legal?

The wattage answer is comfortable: 500 W under a 750 W federal ceiling. The speed answer sits on the 20 mph boundary. Screened against all 51 US jurisdictions, 48 place these figures inside their own definition, two publish no definition, and Hawaii adopts the federal test by cross-reference. Full screen.

What tire size does the Eunorau META275 2.0 have?

27.5 inches by 2.6 inches, a Chaoyang tire on a 27.5-inch black alloy rim, narrower than the 3.0-inch tire on every other current META in this family.

Does the Eunorau META275 2.0 have a torque sensor or a cadence sensor?

A torque sensor. It measures how hard you press and scales the motor to match, rather than switching to a preset level whenever the cranks turn.

Does the META275 2.0 publish frame geometry figures?

No numeric wheelbase or trail figure. The Geometry section of its own product page carries a diagram image shared with the META24's listing, labelled with an unrelated model name. Details.

Will the Eunorau META275 2.0 fit a rider under 5'6" or over 6'1"?

Not by the published range. Under 5'6", the META20 or META24 reach lower. Over 6'1", the META26 reaches two inches higher.

Has the Eunorau META275 2.0 been recalled?

No. Zero federal recalls and zero appearances in CPSC's 359 published product safety warnings, screened September 9, 2026 on a control-tested instrument. Details.

Are Eunorau batteries UL certified?

The META275 2.0's own product page carries a UL CERTIFIED badge, and Eunorau publishes an announcement that its e-bikes have passed UL 2849 testing and its batteries UL 2271. What the standards cover.

What warranty comes with the Eunorau META275 2.0?

Eunorau's warranty is 10 years on the frame and 24 months on battery, motor and electrical components, for bikes bought in the US on or after August 1, 2022.

Is Eunorau a good brand?

That is a brand-level question with a page of its own: our Eunorau brand profile covers the company, the range and the warranty in full.

Limitations of this review

1. Every performance figure here is Eunorau's published specification, confirmed on both of the manufacturer's own surfaces and recomputed where arithmetic allows. The evidence on this page is data and mathematics, and every number is labelled with whose it is.
2. The payload rating's basis is not published. Eunorau states 286 lb without saying whether the bike's own weight counts. This page treats it as gross, the conservative reading, and says so wherever the figure appears.
3. No numeric frame geometry is published for this model. The Geometry section carries a shared diagram image with an unrelated model name in its alt text rather than a wheelbase or trail figure.
4. A telescoping stem is not described for this model. The META20's page names one explicitly; this model's specification does not, so we report the feature as absent from the published record rather than assumed.
5. The specification block's own header text names the wrong version ("META275 1.0") on the page for the 2.0. We read this as a template labelling error. The figures inside that block still match the 2.0's listing elsewhere and our own store's record.
6. Third-party historical figures for "the Meta275" (Electrek, RideReview, Electrified Reviews, a 2025 brand roundup) do not match either of Eunorau's two current listings exactly. We report the mismatch; we do not attempt to reconstruct which configuration existed when.
7. Two of the 51 jurisdictions publish no e-bike definition — Alaska and Kentucky. Hawaii's definition is read from a copy of HRS § 291C-1 deposited from the state's own publisher.
8. State-by-state riding rules are not resolved here. The federal arithmetic and the definitional screen are; path, trail and municipal rules are local, and our law pages cover 33 states.
9. Price, colorways and stock were read on September 9, 2026 through our own Admin API, and all three move.

The bottom line

The Eunorau META275 2.0 is the largest-wheeled bike in a four-model family, and that fact alone tells you less than it seems to. Its rider-height window, 5'6" to 6'1", is the narrowest of the four, seven inches against 11 or 12 on its siblings, and its ceiling ties the smallest-wheeled META20's rather than exceeding it. A bigger wheel bought this bike a higher floor, not a wider window.

Buy it understanding two things. First, the fit range is genuinely tight; measure against it precisely rather than assuming "biggest wheel, most riders." Second, if you searched for a review of this bike before arriving here, you likely found one describing a different configuration. Electrek, RideReview and Electrified Reviews all cover a 67 lb, 13Ah-battery, $1,799 machine that matches neither of Eunorau's two current META275 listings.

Inside its own window, this remains a legally uncomplicated $1,699 Class 2 commuter with a torque sensor, hydraulic disc brakes and the family's largest wheel. Outside it, the rest of the family is worth five minutes before you order.

Expiry conditions

1. Eunorau changes any published weight or fit figure in the META family, which would move the family table and the fit-corridor chart.
2. The second battery's published size or price changes, which would move the 14.4 Wh/mi basis and the 50.0-mile figure.
3. A CPSC recall or warning names Eunorau. The screen was clean on September 9, 2026.
4. A state changes its e-bike definition or its Class 2 minimum age, which would move the 48-of-51 count.
5. Eunorau corrects the specification-block header text or publishes numeric geometry figures for this model, which would resolve the two labelling gaps noted here.
6. A dedicated third-party review of the current META275 2.0 configuration is published, which would change the version-trap finding.
7. Our price or stock moves. $1,699 and 125 units across five colorways were read that day.
