The META20 is EUNORAU's 20" foldable city commuter e-bike, built around a "small footprint, full spec" philosophy. It packs hydraulic disc brakes, a Shimano 7-speed drivetrain and a torque-sensing pedal-assist system into a compact frame.
It is designed for riders who need to fold and stash their bike often, in apartments, offices, RVs and trunks, without giving up real commuter-grade performance. A 48V 500W rear hub motor, a 48V 15Ah Samsung-cell battery with an optional second battery for up to 100 miles, and 20" × 3.0" fat tires make it ready for city streets and light rough terrain.
Key Features
-
500W power ride: A robust hub motor in the rear wheel consistently generates 500 watts of power for a seamless, enjoyable ride.
-
Suspension front fork: Absorbs most of the jarring bumps and shocks on rough routes, reducing fatigue and letting you ride faster.
-
Dual battery design: Add the optional second battery for longer rides with seamless battery transition and less downtime.
-
Torque sensor: The motor responds with more power as you pedal harder, extending your range and enabling faster speeds than an average commuter bicycle.
-
Informative LCD display: Provides essential rider data and Bluetooth connectivity for phone integration, with waterproof connectors.
-
Bell: Easily alert pedestrians and other cyclists of your presence with a simple ring.
-
Comfort saddle: A comfortable saddle for long trips with less fatigue and more enjoyment.
-
Easy-fold frame: A hinge-folding frame collapses in seconds to fit a trunk, an apartment corner or an elevator, ideal for commuting, camping or RV trips.
-
20" × 3.0" fat tires: Wide, high-volume tires increase ground contact for better grip and cushioning on bumpy or wet surfaces, handling city streets and light rough terrain.
-
Brake-sensing tail light: The tail light stays on to alert traffic and automatically brightens when you brake, helping drivers react sooner at night or in low visibility.
-
Adjustable-height stem: A telescoping, quick-release stem lets you adjust handlebar height without tools for a comfortable riding position at any height.
-
7-speed Shimano drivetrain: A Shimano 7-speed derailleur and thumb shifter let you shift smoothly for flat cruising or steep climbs.
-
Rear cargo rack: Strap on panniers, a backpack or grocery bags for hands-free carrying on errands, work trips or a quick grocery run.
-
Bright front headlight: Powered by the main battery and controlled from the display, so you never need to charge or replace light batteries.
Suitable For:
- City commuting
- Apartment and office storage
- RV and camping trips
- Car-trunk transport
- Errands and grocery runs
- Households with riders of different heights

This bike GOOOOOES! | Eunorau Meta (Electric Revolution)

How big is it once folded — will it fit in my trunk or apartment closet?
Folded, the META20 measures approximately 105cm (L) × 78cm (H) × 56cm (W) — compact enough to fit most car trunks, apartment entryways, or RV storage spaces. Measure your intended storage spot against these dimensions before ordering to make sure it's a comfortable fit.
Does the folding frame feel sturdy, or will it rattle and flex while riding?
The hinge-folding mechanism is designed and tested for locking strength and ride stability, so once folded out and locked, the frame stays rigid during normal riding — no wobble or looseness. Just make sure the folding latches are fully clicked into place before each ride to avoid any rattling from an unlocked hinge.
How do I adjust the handlebar height, and is it good for a household with different height riders?
The stem is a telescoping design with a quick-release clamp — loosen the clamp, slide the stem to your preferred height, and re-lock it, no tools required. That also means multiple riders of different heights in the same household can each dial in their own comfortable position.
Is the second battery included, or is one battery enough for daily commuting?
The standard configuration ships with one 48V 15Ah battery; the second battery is an optional add-on. A single battery is enough for most people's daily commute — add the second battery only if you're riding longer distances or want to avoid frequent charging. With both batteries installed, range extends to roughly 100 miles.
Will the fat tires feel harder to pedal, and what terrain are they good for?
20"×3.0" fat tires do have slightly more rolling resistance than narrow road tires, but with pedal assist, you won't notice much extra effort day to day. In exchange, you get better grip and cushioning on bumpy pavement, wet roads, or light unpaved surfaces — a solid trade-off for mixed city riding.
What's the warranty and after-sales support like?
The bike comes with a 24-month+ manufacturer's warranty covering manufacturing defects — normal wear-and-tear parts and labor costs aren't included. After the warranty period, paid parts support is still generally available. Register your bike right after purchase so any future warranty claims get processed faster.

EUNORAU 24-Month+ Limited Warranty
Coverage
- Frame: 10-year limited warranty (replacement or repair)
- Battery: 24 months
- Motor: 24 months
- Electrical components: 24 months
EUNORAU's limited warranty covers manufacturing defects for the original retail purchaser of EUNORAU electric bicycles bought in the U.S. or Canada. It does not cover normal wear and tear or labor costs, and it is not transferable to a subsequent owner.
Warranty Start Date and Registration
For products bought from an authorized EUNORAU dealer, the warranty begins on the original purchase date shown on the purchase invoice or receipt. If proof of purchase can't be provided, the warranty start date is 90 days after the product's manufacturing date, as determined by its serial number. Register your product with EUNORAU promptly after purchase so warranty and after-sales claims can be processed quickly. EUNORAU recommends an inspection by an authorized specialist or dealer after the first year of use. Products used commercially (rental fleets, delivery services, sharing programs) have the standard warranty period reduced by 50%.
Frame Warranty
Covers a replacement or repaired frame only; labor to move parts to a replacement frame is not included. EUNORAU may use scratch-and-dent stock, and frame styles or colors not in stock may be replaced with a compatible style or color. Excluded: corrosion; paint fade, scratches and impact marks; impact damage; non-reversible modification such as drilling or welding; chain guard mounts; and suspension parts.
What Is Not Covered
Ordinary wear and tear (including brake pads, rotors, spokes, grips, shifters, brake cables, casings, tires and tubes, chains, chainrings, cassettes and transmission gears); corrosion from the elements; cosmetic damage or deterioration of the finish; labor for part replacement; damage from accident, abuse, misuse, stunt riding, racing, improper storage, neglect, or exposure to liquids, chemicals, sand or dirt; scratches and dents not caused by EUNORAU; products with a removed or altered serial number or bar code; damage caused by accessories or equipment not furnished or approved by EUNORAU; improper assembly, operation, maintenance or repair that varies from the assembly instructions and manual; external causes such as collision, fire, flood, weather, theft or a blown fuse; using an incompatible or improperly used battery charger; a battery with broken or tampered seals, or used in equipment other than the bike it is specified for; and free gifts or included accessories such as pre-installed racks and fenders.
Shipping Damage
Shipping damage is not covered by the warranty. If you find a problem right after delivery, notify us immediately with photos and/or video of the product and damaged parts, don't use the product, and keep all original packaging.
