Auto-shifting drive
The internal system selects gears automatically for starts, hills and cruising, while torque-sensor assistance keeps the ride smoother than a basic cadence-sensor folding bike.

Ride feel
Power is delivered in response to how hard you pedal, giving Ultra a more controlled commuter feel in stop-start riding.

Control
Hydraulic disc brakes provide controlled braking for everyday commuting.

Storage
Ultra is built for apartments, caravans, suitable car boots and riders who need a compact eBike that is easier to store than a full-size model.

Battery configuration: Ultra and Air 20 Pro use 37V 10Ah EN50604 CAN batteries. *Carbon Pro's 36V 9.6Ah value remains its current listing specification; ADO's Carbon Pro documentation lists 37V 10Ah, and that model's supplied battery revision remains to be confirmed.
Rack accessories: Choose accessories for the exact rack and mounting system. MIK compatibility alone does not establish child-seat suitability or mean accessories are included; observe both rack and bike load limits.
Storage and lifting: Ultra and Pro figures follow their official ADO specifications. Their net weights exclude rear rack and mudguards; Carbon Pro's quoted weight includes them, so these are not like-for-like equipped weights. Battery inclusion is not specified. Folded sizes are not packaging dimensions; no battery-removed weights are stated. Leave clearance around the folded bike and consider a folding and lifting demonstration.
Range: Maximum assisted figures are not guaranteed. Rider and cargo weight, assistance level, terrain, wind and tyre pressure affect actual range. Optional range-extender batteries are not included in the standard-range comparison.
