Electric Folding Bike ADO Air 20S

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


ADO Air 20S

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

The ADO Air 20S folding electric bike is an ideal choice for daily urban cyclists, students, and travelers looking for an exceptionally light, clean, and reliable mode of transport. Its compact folding frame and low weight of just 18 kg make it incredibly easy to carry up stairs, store in an office, or transport in a car boot or on public transport. It is suitable for riders with heights ranging from 150 cm to 200 cm, ensuring wide usability for the whole family.

ADO Air 20S

Gears icon Carbon Belt-Drive – No rust or lubrication

Forget dirty, greasy chains and constant maintenance. The ADO Air 20S is equipped with an advanced Carbon Belt drive, ensuring 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 stay perfectly clean during your commute, and power transfer to the wheel is direct and extremely efficient.

ADO Air 20S

Motor icon Smart Torque Sensor and Brushless Motor

At the heart of the propulsion system is an advanced smart torque sensor that precisely detects the force of your pedal pressure and instantly adjusts motor assistance in milliseconds. This allows for a completely natural riding experience without jerky starts. Even when riding uphill or starting from a standstill, you will immediately receive optimal support from the brushless hub motor, which in its road-legal version develops 250 W of power and torque up to 37 Nm (the international version reaches a maximum power of 350 W and torque up to 42 Nm).

ADO Air 20S

Battery icon Portable and Powerful Battery with Range up to 100 km

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

ADO Air 20S

Suspension icon Front Hydraulic Suspension for Superior Comfort

Compared to classic rigid folding bikes, the ADO Air 20S features front hydraulic forks (Hydraulic Shock Absorber Fork). The suspension effectively dampens vibrations and impacts when riding over bumps, gravel, or cobblestones, significantly reducing arm and back fatigue and ensuring an exceptionally stable and comfortable urban ride.

ADO Air 20S

Brakes icon Powerful Hydraulic Disc Brakes

Top-tier hydraulic disc brakes ensure safe and quick stopping in all weather conditions. They provide consistent braking force with minimal effort on the brake lever, giving you complete control over the bike on dry, wet, and slippery urban surfaces alike.

ADO Air 20S

Display icon Color IPS Display and Smart ADO App with Navigation

The integrated 2.4-inch color IPS display boasts high brightness, allowing for excellent readability of speed, range, and assistance level data even in direct sunlight. The display has a high water protection rating of IPX7. Via Bluetooth, you can connect to the smart ADO Smart APP, which allows you to monitor riding statistics and transmit navigation directions directly to the bike's display.

ADO Air 20S

Weight icon Ultralight Aluminum Frame and Easy Folding

The bike's frame is made from lightweight and structurally optimized aluminum. The net weight of the bike is just 18 kg (without accessories), allowing for easy one-handed lifting. The bike folds in just a few seconds to compact dimensions of 86 x 52 x 68 cm, enabling storage in the narrowest corners of your home or office. Despite its lightweight design, the bike has a high load capacity of up to 120 kg.

ADO Air 20S

Tires icon 20-inch Puncture-Proof Tires and Safe Lighting

The bike is equipped with robust 20-inch tires with a width of 1.95 inches, which are puncture-protected and offer excellent grip on urban streets and well-maintained gravel paths. For excellent visibility at night or in poor weather, a bright front headlight with an illumination of 1200 lumens and **E-Mark** certification ensures visibility, is water-resistant to IPX5 standard, and a reflector is installed at the rear for added safety.
