This Model Is Fully Compliant With UK Road Regulations
This bike is built to comply with UK Electrically Assisted Pedal Cycle (EAPC) regulations, meaning it can be used on public roads and cycle paths without registration, tax, or a licence. Motor assistance is limited to 250W and cuts off at 15.5 mph (25 km/h).
See UK LegislationYour daily commute, reimagined
The ADO Air 20S is built for riders who want to glide through city streets, fold up for the train, and store their bike in a hallway cupboard. It pairs a lightweight aluminium frame with a smooth carbon belt drive, so you get a clean, quiet ride without the hassle of chain oil. With a 250W motor and 15.5 mph assisted speed, it keeps you within UK e-bike regulations while making every journey feel effortless.

Effortless power for city hills
The 250W rear hub motor delivers 37 Nm of torque, helping you accelerate from traffic lights and climb moderate inclines without breaking a sweat. Pedal assistance cuts out at 15.5 mph, so you stay legal on UK roads while still arriving fresh. The torque sensor responds to how hard you pedal, giving a natural, intuitive boost that feels like a tailwind.

Go further on a single charge
The Samsung 36V 9.6Ah battery gives you up to 62 miles of assisted range, depending on rider weight, terrain, and assist level. That’s enough for a week of short commutes or a long weekend ride along the canal towpath. The battery is removable, so you can charge it at your desk or in the flat, and it refills in 4–6 hours.

Comfort that smooths the road
The front suspension fork absorbs bumps and potholes, protecting your wrists and back on uneven city streets. The 20-inch tyres are wide enough to add cushioning, while the adjustable handlebar height lets you find a relaxed, upright riding position. Whether you’re dodging potholes in Manchester or cruising along Brighton seafront, the ride stays composed.

Stop with confidence, even in rain
Hydraulic disc brakes give you strong, predictable stopping power in wet or dry conditions, so you can brake late and safely when a car pulls out. The IPX5 waterproof rating means the bike can handle British drizzle without electrical worries. A 1200-lumen headlight helps you see and be seen on dark winter evenings, and the reflector tail light adds extra visibility.

Clear controls and smart connectivity
The IPS colour display shows your speed, battery level, and assist mode at a glance, even in bright sunlight. You can switch between 0–3 levels of pedal assist to match your energy or the terrain. The bike also connects to the ADO Smart App, letting you track rides, adjust settings, and lock the bike digitally for extra peace of mind.

Built to fold, carry, and store
The aluminium frame folds down to 77 × 33 × 85 cm, small enough to slide under a desk or into a car boot. At 40 lbs, it’s light enough to carry up a flight of stairs or onto a train. The carbon belt drive needs no lubrication and lasts far longer than a chain, so maintenance is minimal. It supports riders up to 265 lbs and fits heights from 150 cm to 200 cm, making it a practical choice for many UK commuters.
