Eunorau META20 Review 2026: 63.4 lb, 500 W, $1,699

500 W hub · 55 N·m · torque sensor · 720 Wh · 20 MPH · 63.4 lb · folds to 105×78×56 cm · $1,699 · verified September 9, 2026

Quick Answer — The Eunorau META20 1.0 is a $1,699 folding commuter: 500 watts, a torque sensor, 20-inch wheels, 20 MPH. Folding costs it 1.7 lb against the family's lightest member (the non-folding META24) — and it still weighs 5.0 lb less than the two bigger-wheeled siblings.

Folded, it measures 105×78×56 cm (41.3×30.7×22.0 in), by Eunorau's own diagram for this model. Buy it when the bike has to disappear into a trunk, a closet or an elevator between rides.

Every figure above is Eunorau's own published specification, read on both of the company's surfaces the same day and recomputed against three sibling spec tables. No dedicated third-party review of this specific model exists as of this writing, a rarer position than either the META24 or META26 hold.

How we verified this Eunorau META20 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, across 32 labelled rows. That comparison gets its own section 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 weights, and the subtraction — both the payload headroom and the folding-cost comparison — is recomputed fresh from all four spec tables the same week; none of it carries over from an earlier page.

Price, colorways and inventory come from our own store 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 by script 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 with known open warnings before Eunorau's silence was believed.

No dedicated review of this specific model turned up in a search of the sites that do cover this family. Electrek has reviewed the META24 and the META275; Off-Road Ebike Source has a dedicated META26 1.0 review. Neither has published one for the META20 as of this writing. What follows claims no other advantage from that, only that the arithmetic below has not already been done somewhere else.

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.

What folding costs — 1.7 lb one way, 5.0 lb the other

Shoppers guess this one in two different wrong directions. Some assume a folding bike is automatically the lightest of a family: smaller wheels, a smaller package, must weigh less. Others assume the opposite: a folding hinge is extra hardware, so it must be the heaviest. Eunorau's own four spec tables, read the same week, say neither is true.

Same 286 lb rating, same $1,699, on all four. The folder sits second from the bottom of four.

Two comparisons, and they point opposite directions. Against the family's lightest member — the non-folding META24 — folding costs this bike 1.7 lb. That is roughly what a hinge, a locking latch and the reinforced frame joint add when the wheel size is nearly the same. But against the two bigger-wheeled, non-folding siblings, the META20 is 5.0 lb lighter. A 26-inch or 27.5-inch wheel, its matching rim and its longer tubes cost more mass than a folding joint does.

The finding, stated plainly: the hinge is not what makes a META heavy. The wheel size is. If your mental model was "folding always costs weight," it is right by 1.7 lb against the single lightest sibling and wrong by 5.0 lb against the other two. Both comparisons are true at once, which is why a shopper needs the whole family table rather than one number from one page.

5'1" to 6'1": the widest low end in the family

Eunorau publishes a rider-height range of 5'1" to 6'1" for the META20 — a full two inches lower at the floor than the META24's 5'3" and three inches lower than the META26's 5'4". Of the four wheel sizes Eunorau sells at this price, the 20-inch folder reaches the shortest rider.

Twenty-inch wheels and a folding hinge both push the standover down. The published range reflects it.

The saddle backs that up. The rendered product page prints the saddle height as 29.9" to 37.0" to ground, folded directly into the Saddle specification row instead of carried in a row of its own — 0.8 inches lower at the floor than the META24's dedicated seat-to-ground row, and it is the number that decides whether a shorter rider can put a foot down flat without dismounting.

Two things explain the low end, and only one of them is the wheel:

1. The 20-inch wheel itself sits lower under the frame than the 24- or 26-inch wheels on the same platform, which is most of why the standover drops.
2. The telescoping stem adjusts without tools. Eunorau's own FAQ for this model describes a quick-release clamp that lets the bar height move to the rider; nothing about it is fixed — useful on its own, and doubly useful in a household where more than one person rides the same bike.

The bike is also the shortest of the family nose to tail, even before it folds. Eunorau's own geometry table gives a total length of 1,693 mm (66.7 in) for the META20, against 1,769 mm (69.6 in) for the META24 and 1,874 mm (73.8 in) for the META26. Read the wheelbase row and there is a genuine surprise sitting next to that: at 1,143 mm (45.0 in) the META20's wheelbase is longer than the META24's 1,113 mm. A folding frame trims the overhang at each end — front fork rake and rear triangle length — more than it trims the distance between the axles. The published total-length figure is the one that matters for a hallway or an elevator door either way.

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.

Two hundred and fifty watts of margin under the federal ceiling, on a machine capped at 20 MPH.

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, the wording deserves the same care every META review gives it: the statute says less than 20 mph on motor power alone, and Eunorau publishes a maximum of 20 MPH. A published figure sitting exactly on the line is met at the boundary and not rounded away.

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, and Class 2 is the least restricted of the three tiers in most states that have adopted the framework.

We screened the published figures — 500 W, 20 MPH, thumb throttle — against all 51 US jurisdictions' own statutory definitions:

Zero jurisdictions place these published figures outside their definition. For comparison, our review of the moped-style Eahora Romeo Pro covers a 1,200 W machine, 1.6 times the same federal ceiling and a different conversation before the bike arrives.

What that means for you. This is a bike you buy without first solving a legal question. Local rules on paths and trails still vary, and our state e-bike law pages work through 33 states from the statutes — but the starting position here is the permissive one.

Fifty miles on the battery that comes in the box

The battery is 48 V 15 Ah on both of Eunorau's surfaces, which multiplies to 720 watt-hours exactly.

Eunorau advertises up to 100 miles, and prints the basis right beside the claim: "48V 15Ah Battery + Second Battery 15Ah." The second pack is an optional accessory, listed on the same page at $499. So the 100-mile figure rests on 1,440 Wh while the bike ships with 720 Wh.

That is the same basis and the same arithmetic our META24 review found for its sibling, and it should be — both bikes share the identical battery, controller and motor. Apply 14.4 Wh/mi to the 720 Wh pack that ships and you get 50.0 miles. Low assist, level ground, real pedalling; use the throttle, climb hills or carry a load and the number comes down from there.

The buying decision is the same one every META in this family creates. Under roughly twenty miles each way, one pack covers the week. Over that, budget the $499 second pack with the bike itself, so the gap gets decided up front, before it becomes a discovery three weeks in.

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 all 32 labelled rows.

26 rows are identical. 3 differ, and all 3 differences add detail without contradicting anything.

One additional row, Box Dimensions, appears on the feed (148 L × 31 W × 79 H cm) and is absent from the rendered page — the box the bike ships in — a different measurement from the folded bike itself; that figure belongs to freight planning, a separate question from storage below.

There is no version of this specification where a buyer gets a different bike depending on which page they read. Every figure that decides anything a buyer acts on (voltage, amp-hours, watts, torque, top speed, weight, payload, rider height, tire size, rotor size, charging time) reads the same on both.

105 by 78 by 56 centimeters: where a folder wins

Everything above this section is about what folding costs. This section is about what it buys — and it is the reason to choose this bike over its non-folding siblings in the first place.

Eunorau's own diagram, matching the FAQ text on the same product page — an internal check the manufacturer's own numbers pass.

Eunorau's own product FAQ for this model states the folded footprint directly: approximately 105 cm (L) × 78 cm (H) × 56 cm (W) — 41.3 × 30.7 × 22.0 inches. A separate diagram on the same page carries the identical three numbers, which is a small but real cross-check: two different assets on the maker's own page agree with each other.

What that unlocks, in the maker's own words: "compact enough to fit most car trunks, apartment entryways, or RV storage spaces." Two independent sources found while harvesting demand for this page back the general claim without naming this bike specifically — a folding-bike buying guide's storage FAQ and a fit-in-your-trunk guide from a different e-bike retailer both treat "under roughly 33 inches long, folded" as the rough threshold for a sedan trunk; this bike's 41.3-inch folded length runs longer than that, so it is a hatchback-or-SUV-trunk fold rather than a sedan-trunk guarantee, and a shopper planning to load one into a small sedan should measure their own trunk opening before ordering.

Parked, feet down — the fold is what makes this the bike you bring rather than the bike you leave behind.

Three published numbers turn "it folds" into an actual answer to "will it fit":

1. 41.3 inches long, folded. Longer than a small hotel-room roll-aboard laid flat, short enough for most hatchback and SUV trunks, and worth measuring against a sedan's before assuming.
2. 22.0 inches wide, folded. Narrower than most single doorways, which is the number that decides an apartment hallway or an elevator corner.
3. 63.4 lb to actually lift. A compact fold does not make the bike light — this is still a fat-tire e-bike with a hub motor and a battery, and the folded footprint says nothing about how it feels to carry up a flight of stairs. If stairs without an elevator are part of the plan, weigh that against the storage win before ordering.

Where this bike genuinely beats its non-folding siblings: a closet instead of a bike room, the back seat or trunk of a car for a weekend trip, an RV or boat locker, an office corner during the workday. Where it does not help: the ride itself. Folded or not, the META20 carries the same 500 W motor, 55 N·m torque, 20 MPH cap and 720 Wh battery as the META24 and the META26 — folding changes what you can do with the bike between rides rather than what it does on one.

Brakes, gears and the parts your hands are on

Kenda 20" × 3.0" on a black alloy rim, with a suspension fork and a 180 mm rotor behind it.

Braking. Hydraulic disc brakes on 180 mm rotors, front and rear, with motor-cutoff switches in both levers so the assistance stops the instant you pull. 16 CFR § 1512.5(b)(1) holds a bicycle to a 15-foot stop at the test speed its own cross-reference sets, and hydraulic discs on a 63.4 lb, 20 MPH machine are proportionate hardware for that requirement.

Shimano's 7-speed cassette and derailleur, a 48-tooth chainring, and the folding hinge just above the chainstay.

Shifting. A SHIMANO ASLM3157RC 7-speed shifter and a Shimano derailleur 7-speed freewheel, turned by a 48T chain-wheel crank on a 170 mm forged aluminum crank arm. That chainring is six teeth larger than the META24 and META26's 42T — a taller gear that compensates, in part, for the smaller 20-inch wheel's shorter roll-out per crank revolution.

The display and the tire. A BC182 LCD with Bluetooth and EUNORAU GO app support, the same unit fitted across the family. The tire is Kenda 20" × 3.0", a different tire brand from the META24's Innova rubber at the same size — one of the small component substitutions that shows up when you diff a family across models; the spec sheet is not identical everywhere but the wheel.

The stem telescopes on a quick-release clamp — no tools, and no fixed cockpit to work around.

The cockpit. A telescoping, quick-release stem adjusts bar height without tools, which Eunorau's own FAQ for this model frames around multiple riders sharing one bike as much as around fit. A thumb throttle, hydraulic brake levers and an LED headlight round out the bar.

Rack and fender fitted from the factory — and, per Eunorau's own product description, a brake-sensing tail light that brightens when you slow down.

The parts that make it a commuter rather than a toy. A rear rack and a full-coverage fender are fitted as standard. Front and rear LED lighting is fitted, and Eunorau's own description for this model highlights a brake-sensing tail light that brightens automatically under braking — a detail we have not found called out the same way on this family's other product pages, so we note it as this model's own copy rather than a family-wide feature.

Charging. A US-standard 2.0 A smart charger and a published 5 to 7 hour charge for the 720 Wh pack — unchanged from the rest of the family, since the battery, controller and charger are shared parts.

Buying it from us

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

Where every number on this page comes from, including the ones that are not ours. The Kenda tire brand and the 48T chainring are Eunorau's own, published on both of its surfaces. The 50.0-mile figure is arithmetic over the maker's published watt-hours, shown as arithmetic so you can check the working. The 1.7 lb and 5.0 lb folding-cost figures are subtraction across four of the maker's own spec tables read the same week. Where a figure is ours we say so; where it is the maker's we say that too.

Alpine White, Steel Blue, Pastel Pink, Deep Crimson 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, which means the money is not part of this decision. Your body, your storage and whether you need the fold are.

Read the rider-height row across all four and the pattern holds up as consistent rather than incidental. The 20-inch folder reaches two inches lower than the 24, three lower than the 26, and five lower than the 275 2.0's floor. If you are near the bottom of any of those ranges, the META20 is worth checking first regardless of whether you need the fold.

The trade this table makes explicit: the META24 is lighter by 1.7 lb and carries more payload headroom (see its own review for that arithmetic); the META20 folds and reaches shorter riders. Neither fact cancels the other — they are the two reasons to pick between them.

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 Jack — and the fold is the reason. Maya lives in a building with a tight storage closet and commutes inside a bike lane; the same fold that solves her space problem is irrelevant to Jack, who is 6'1" (right at this bike's ceiling) and rides ground the 20-inch city tires were never built for — the FAT-AWD 3.0 is his bike at the same $1,699. A fit window and a folded footprint tell you whether a bike will fit your body and your closet. Neither tells you whether it suits your terrain.

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.
• Product safety warnings: Eunorau appears in 0 of the 359 warnings in CPSC's complete published warning listing.

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 was queried for a term with 19 known federal e-bike records and returned all 19. A search that cannot find what is certainly there cannot be trusted when it finds nothing, and matching is done on whole words because a substring search for a short brand name inside "electric" returns hundreds of unrelated records.

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 META20 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, which required an evaluation of all of the battery components; from wiring, the case materials, battery cells and the overall system."

UL 2849 covers the whole electrical system — motor, controller, battery and charger evaluated as one combination. 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, and other cities have followed.

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. That takes a day and costs you nothing.

Whatever the paperwork says, charge any pack on a hard surface, away from your exit route, on the charger it shipped with. CPSC's own guidance is a five-minute read and it is the best five minutes you will spend on this purchase.

Green flags / Red flags

Green flags

• The lowest published fit floor in the family — 5'1", two inches under the META24 and three under the META26.
• Folds to 105×78×56 cm (41.3×30.7×22.0 in), confirmed by two independent assets on the maker's own product page (the FAQ text and the dimension diagram) that agree with each other.
• 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, on a bike that also comes with a rack, full fenders and lights fitted.
• Both maker surfaces agree on every load-bearing row, checked across 32 labelled specifications 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, with 24 months on battery, motor and electrics.
• Five colorways, all five in stock, 125 units as this publishes.

Red flags — meaning who this bike is wrong for

• Wrong if you assumed folding meant the lightest bike in the family. At 63.4 lb it is 1.7 lb heavier than the non-folding META24. If maximum lightness and payload headroom matter more than the fold, that bike is the better fit.
• Wrong if you needed 100 miles out of the box. That figure is built on two 15 Ah packs; the one that ships is worth 50.0 miles at the same effort, and the second pack is $499.
• Wrong if you want to keep pace with traffic. Twenty miles an hour is the cap by design, and it is the price of the bike-lane access above. If speed is the requirement, the Eahora Romeo Pro has it and carries the legal question this bike does not.
• Wrong if you are under 5'1" or over 6'1". Both ends are published. Over the ceiling, the META26 reaches two inches higher.
• Wrong if your ground is loose. City tires 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. A low step-through frame lowers the leg-over height and does nothing about balance; three wheels do, and the ONE-TRIKE 2.0 is our 500 W answer.
• Wrong if you need real cargo capacity. A rear rack is not a cargo deck; Eunorau's two longtail cargo bikes, the G30-CARGO and the MAX-CARGO, both publish 440 lb of payload against this bike's 286 lb, and either is built to carry that weight as everyday cargo — check the state-by-state legal margin between the two before picking, since they run different motor wattages.

Buy it if / Buy something else if

Buy it if the bike has to fold — into a closet, a car trunk, an elevator ride, an RV or boat locker between uses — or your body sits at the short end of this family's fit range. That combination is what the 5'1" floor, the 105×78×56 cm fold and the 500 W Class 2 rating add up to, and no other bike in this family folds at all. The torque sensor is what stops it feeling like a scooter with pedals bolted on.

Buy something else if any of that misses. If you want the lightest META and the most payload headroom and don't need the fold, the Eunorau META24 is 1.7 lb lighter at the same price. If your problem is loose ground, the Eunorau FAT-AWD 3.0 is the same $1,699 with a motor at each end and 375 lb of payload. If it is speed and you have somewhere to use it, read our Eahora Romeo Pro review before you spend anything. If it is balance, the Eunorau ONE-TRIKE 2.0 puts the same 500 W and 20 MPH on three wheels.

Before you buy: the checklist

1. Measure against 5'1"–6'1", then against 29.9" of minimum saddle height. The second number is the one that decides whether you can put a foot down comfortably.
2. Measure the space you'll actually store it in — closet, trunk, elevator — against 105×78×56 cm (41.3×30.7×22.0 in) folded. Not every trunk is a trunk; a small sedan's may run shorter than this bike's folded length.
3. Add up your loaded weight against 222.6 lb. You, clothes, helmet, lock, bag, rack contents. The bike's 63.4 lb is already subtracted.
4. 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, at $499.
5. Check your state's Class 2 rules, especially the minimum age if the rider is a teenager.
6. Pick a colorway on the product page. All five are in stock today, which is a sentence with a short shelf life.

Frequently asked questions

How much does the Eunorau META20 weigh?

63.4 lb, published by Eunorau on both of its surfaces — 1.7 lb more than the family's lightest member, the non-folding META24, and 5.0 lb less than the META26 or META275 2.0.

Is a folding electric bike heavier than a non-folding one?

Not always, and this family is the proof. The META20 folds and weighs 63.4 lb; the non-folding META24 in the same family weighs less (61.7 lb), but the two non-folding, bigger-wheeled siblings (META26, META275 2.0) weigh more (68.4 lb each). Wheel size moved this family's weight more than the fold did. Full arithmetic here.

How big is the Eunorau META20 folded?

Approximately 105 cm × 78 cm × 56 cm — 41.3 × 30.7 × 22.0 inches — by Eunorau's own FAQ and diagram for this model, which agree with each other. Details here.

What is the weight limit on the Eunorau META20?

286 lb total payload capacity. Eunorau does not state whether the bike's own weight counts toward it, so treat the working figure as 222.6 lb for rider plus cargo — 286 minus the bike's own 63.4 lb.

What height is the Eunorau META20 for?

5'1" to 6'1" is the published rider range — the lowest floor of any META we stock — with a saddle height of 29.9" to 37.0" to ground.

How far does the Eunorau META20 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, which is 1,440 Wh and implies 14.4 watt-hours per mile. Apply that same efficiency to one pack and you get 50.0 miles. Working here.

How fast does the Eunorau META20 go?

Twenty miles per hour, which Eunorau publishes as the maximum. That is the Class 2 ceiling in the states using the three-class system, and Eunorau's own specification banner prints "CLASS: Class 2."

Is the Eunorau META20 street legal?

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

Does the Eunorau META20 have a torque sensor or a cadence sensor?

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

What is the difference between the META20, META24, META26 and META275?

Wheel size, fit range, weight and whether it folds — and all four are $1,699. The 20 is the only one that folds and reaches the shortest riders; the 24 is the lightest and carries the most payload; the 26 rolls most efficiently; the 275 2.0 has the narrowest published fit range. Side by side.

Will the Eunorau META20 fit in my car trunk?

Folded, it measures 41.3 inches long by 22.0 inches wide by 30.7 inches tall. That fits most hatchback and SUV trunks; a small sedan's trunk opening should be measured against 41.3 inches before you assume it will fit, since general folding-ebike storage guides put roughly 33 inches as the length that guarantees a sedan trunk.

Does the META20 come with a rack and fenders?

Yes. Eunorau fits a rear rack and a full-coverage fender as standard, along with front and rear LED lighting, a suspension fork and a C7 comfort saddle.

What brakes does the Eunorau META20 have?

Hydraulic disc brakes on 180 mm rotors, front and rear, with motor-cutoff switches in both levers.

Has the Eunorau META20 been recalled?

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

Are Eunorau batteries UL certified?

The META20'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. If you need a certificate number for this model specifically, we will request it from Eunorau for you. What the standards cover.

What warranty comes with the Eunorau META20?

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. Buying from us means we handle the registration and any claim.

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, which is the conservative reading, and says so wherever the figure appears.
3. The charger's output voltage is not published, only its 2.0 A rating, so the 5–7 hour charge claim could not be derived the way the range figures were.
4. The freewheel's tooth range is not published, so top-gear road speed could not be computed. Eunorau publishes the 48T chainring and a 7-speed Shimano freewheel and stops there.
5. The car-trunk comparison in the storage section draws on general folding-ebike storage guidance, not a model-specific trunk-fit test. No trunk this bike was actually placed into was measured; the comparison is Eunorau's own folded dimensions set beside published general guidance, and a reader with an unusually small trunk should measure their own vehicle.
6. Two of the 51 jurisdictions publish no e-bike definition — Alaska and Kentucky — so the screen returns no verdict for them rather than a pass. Hawaii's definition here is read from a copy of HRS § 291C-1 deposited from the state's own publisher.
7. 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, each read from its own statute.
8. No dedicated third-party review of this specific model was found as of this writing. That is stated as a fact about the review landscape, not as a claim that none will ever exist.
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 META20 1.0 is the one to buy when the bike has to disappear between rides, and the arithmetic behind that answer runs in two directions at once. Folding costs this bike 1.7 lb against the lightest bike in its own family — real, and worth knowing before you assume a fold is automatically the light choice. But it saves 5.0 lb against the two bigger-wheeled, non-folding siblings, because a 26-inch or 27.5-inch wheel costs more mass than a hinge does. Add the lowest published fit floor in the family (5'1") and a folded footprint of 105×78×56 cm, confirmed by two of Eunorau's own page assets agreeing with each other, and you have the family's most storable machine rather than its lightest.

Buy it understanding two things. The 100-mile headline belongs to a two-battery configuration that costs another $499; one pack is worth 50.0 miles at the maker's own implied efficiency. And the fold changes what you can do with the bike between rides — trunk, closet, elevator — not what it does once you're on it, which is what the META24 and the META26 already do at the same price.

If a folding bike has been the plan all along, this is the specification that tells you what the fold actually costs and what it actually buys, in the same two numbers.

Expiry conditions

1. Eunorau changes any published weight in the META family, which would move every bar in the folding-cost chart.
2. The second battery's published size or its $499 price changes, which would move the 14.4 Wh/mi basis and the 50.0-mile figure with it.
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 publishes a per-model UL certificate number, which would replace the badge and the range-wide announcement quoted here.
6. A dedicated third-party review of this exact model is published, which would change the zero-coverage statement in the methodology and limitations sections.
7. Our price or stock moves. $1,699 and 125 units across five colorways were read that day.
