Summary of Reviews
We have read all expert and user reviews on the ADO Air 20. In summary, this is what cyclists think. Published May 05, 2025 by Nick Koleszar.
10 reasons to buy
- The Air 20 comes in three builds: a rigid-fork base version with a single-speed drivetrain and Pro (2-speed) and Ultra (3-speed) with suspension forks and auto-shifting internally geared hub motors.
- The base Air 20 is light for a folding e-bike at this price point, though it weighs 42lb, 7lb more than ADO’s claims.
- Experts laud the smooth pedal assist and responsive torque sensor.
- The Dayco carbon belt drive is durable, quiet, clean, and low-maintenance.
- Reviewers appreciate hydraulic disc brakes on a folding e-bike and praise the braking power.
- ADO’s warranty covers the frame for five years.
- Testers and owners enjoy the automatic shifting on the Pro and Ultra, saying it eases pulling away and climbing hills.
- The compact fold (33.86” x 18.9” x 24.8”) makes the Air 20 easier to store or transport than competing e-folders.
- Reviewers test the Air 20's range at 36 to 46 miles, beating many comparable bikes.
- ADO offers a 201.6Wh range extender battery for this bike.
8 reasons not to buy
- The 15.5mph speed limit doesn’t make the most of US e-bike rules.
- Testers bemoan the Air 20's poor hill-climbing ability using either throttle (International version only) or pedal assistance, but owners say auto-shifting makes the Pro and Ultra better in this regard.
- All versions of this bike are heavier than advertised, frustrating buyers.
- Pro and Ultra buyers must pay extra for a throttle.
- Testers taller than 6’ say the stated 4'11” to 6'6” height range is unrealistic.
- This bike has no security feature to prevent theft of the easily removed battery.
- A reviewer finds the ADO app offers limited utility, and the Android version wouldn’t pair with the bike.
- The Air 20's practicality is reduced by the lack of fenders, and the single-speed doesn't have a cargo rack.
Bottom line
ADO’s Air 20 is an e-folder with a 250W motor, a 245Wh battery, and 20” wheels. It’s available as a single-speed with a rigid fork or a suspension fork and 2-speed or 3-speed internally geared hubs. Testers applaud the low weight, quick fold, durable belt drive, and smooth, responsive pedal assist. The automatic shifting (Pro and Ultra) also wins praise. Complaints include the misleading stated weight, unrealistic fit and battery range, and weak hill-climbing ability. Despite the Air 20’s limitations, it’s still considered a great e-commuter for areas without many hills.Expert Reviews
