ADO Air 20S Folding Electric Bike

The first 20-inch folding e-bike with a carbon belt drive, torque sensor, and hydraulic suspension

Electric bicycle ADO Air 20S – two people riding by the water

Benefits icon Who is this folding electric bike best suited for?

The ADO Air 20S folding electric bike is the ideal choice for daily city commuters, students, and travelers looking for an extremely lightweight, clean, and reliable mode of transport. Thanks to its compact folding frame and low weight of just 18 kg, the bike is incredibly easy to carry up stairs, store in the office, or transport in a car trunk and on public transit. It is tailored for riders from 150 cm to 200 cm tall, ensuring wide usability for the whole family.

Transmission icon Carbon Belt-Drive – Rust-free and maintenance-free

Forget about dirty, greasy chains and constant maintenance. The ADO Air 20S is equipped with an advanced Carbon Belt drive, which ensures quiet, smooth, and clean operation. The belt is rust-resistant and lasts between 20,000 and 30,000 km of operation without the need for lubrication or servicing. Your clothes will remain completely clean during your commute, and the power transfer to the wheel is direct and highly efficient.

Electric bicycle ADO Air 20S – man riding light blue variant in city

Motor icon Smart Torque Sensor and brushless motor

The heart of the drive system is an advanced smart torque sensor that precisely detects your pedaling force and adjusts the motor assistance in a millisecond. This provides a completely natural riding feel without sudden starts. Even when riding uphill or starting from a standstill, you will instantly receive optimal support from the brushless hub motor, which in the road-legal version develops 250 W of power and up to 37 Nm of torque (the international version reaches a maximum power of 350 W and up to 42 Nm of torque).

Electric bicycle ADO Air 20S – three people riding different colour variants

Battery icon Portable and powerful battery with up to 100 km range

The bike uses a high-quality portable battery with a capacity of 36V 9.6 Ah, which is elegantly hidden in the seatpost. The battery can be easily removed and charged anywhere – at home or in the office. With a full charge taking between 4 and 6 hours, you can ride up to 100 km under optimal conditions. The battery also complies with the strict UN 38.3 testing standards for lithium-ion batteries.

Electric bicycle ADO Air 20S – front suspension and fender close-up

Suspension icon Front hydraulic suspension for premium comfort

Compared to standard rigid folding bikes, the ADO Air 20S boasts a front hydraulic fork (Hydraulic Shock Absorber Fork). The suspension effectively absorbs vibrations and shocks when riding over speed bumps, gravel, or cobblestones, significantly reducing hand and back fatigue while ensuring an exceptionally stable and comfortable city ride.

Electric bicycle ADO Air 20S – front disc brake detail

Brakes icon Powerful hydraulic disc brakes

For safe and quick stopping in all weather conditions, the bike features premium hydraulic disc brakes. They provide consistent braking force with minimal effort on the brake lever, giving you complete control over the bike on dry, wet, and slippery city surfaces.

Electric bicycle ADO Air 20S – waterproof display close-up

Display icon IPS color display and ADO smart app with navigation

The built-in 2.4-inch IPS color display features high brightness, ensuring excellent readability of speed, range, and assist level data even under direct sunlight. The display has a high water resistance rating of IPX7. Via Bluetooth, you can connect to the ADO Smart APP, which allows you to track ride statistics and send navigation instructions directly to the bike's screen.

Electric bicycle ADO Air 20S – man carrying folded bicycle in urban setting

Weight icon Ultra-lightweight aluminum frame and easy folding

The bike frame is made of lightweight and structurally optimized aluminum. The net weight of the bike is just 18 kg (excluding accessories), making it easy to lift with one hand. The bike folds in just a few seconds to compact dimensions of 86 x 52 x 68 cm, allowing you to store it in the tightest corners of your home or office. Despite its lightweight design, the bike has a high load capacity of up to 120 kg.

Electric bicycle ADO Air 20S – front wheel, mudguard, and headlight close-up

Tyres icon 20-inch puncture-resistant tires and safe lighting

The bike is equipped with robust 20-inch tires with a width of 1.95 inches, which are puncture-resistant and offer excellent grip on city streets and paved gravel paths. For great visibility at night or in poor weather, a bright front headlight with a light output of 1200 lumens and **E-Mark** certification is provided, water-resistant to the IPX5 standard, while a reflector is mounted at the rear for extra safety.
