ADO Air 20 Folding Electric Bike – Carbon Belt Drive

ADO Air 20 Folding Electric Bike

The ADO Air 20 is a compact folding electric bike with torque-sensing assistance and a clean single-speed carbon belt. Its 250W rear-hub motor responds to pedalling effort, helping starts and everyday journeys feel smooth without the maintenance of a conventional chain.

A removable 36V 9.6Ah seatpost battery, 20 × 1.95-inch tyres, hydraulic disc brakes and an aluminium folding frame make this original Air 20 configuration easy to store and straightforward to own. It uses a rigid front fork rather than the suspension fitted to later Air 20S models.

Natural torque-sensor assistance

The 250W rear-hub motor adjusts support in response to pedalling effort through a torque sensor, producing progressive assistance for starts and steady everyday riding.

Removable seatpost battery

The 36V 9.6Ah lithium-ion battery is integrated into the seatpost and removes for charging or secure storage. The maximum quoted assisted range is up to 62 miles (100km), with a typical recharge taking approximately 4–6 hours.

Clean belt drive and folding frame

The single-speed carbon belt runs quietly and needs no chain oil. Hydraulic disc brakes support controlled stopping, while the frame, handlebar and pedals fold to reduce the bike's storage footprint. An IPS colour display works with the ADO Smart App for ride information and connected support.

Configured for UK EAPC use This bike is supplied with usable pedals, a motor rated at 250W continuous output, no throttle and pedal assistance that cuts out at 15.5mph (25km/h). Riders must be aged 14 or over in Great Britain. Keep the electrical system unmodified if you intend to use it as an EAPC. Read our UK e-bike law guide. Range notice Quoted range figures are maximum estimates, not guarantees. Actual range varies with rider and cargo weight, assistance level, gradients, surface, stops and starts, tyre pressure, temperature, wind and battery condition.
