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.

Adding the throttle too a 250W doesn't really do much for me in regards to climbing hill but it can help a bit on the straights. The seat could of been a bit wider and longer plus they could of installed the magnet locking free of charge.
It lasts about a week on a single charge as I only do 4 miles a day.
I think I should of brought the 350W but Im no rebel .
Very good features.
