ADO Air 20 Ultra 2026 Folding Electric Bike
Three-stage seamless folding city electric bike with automatic transmission and belt drive

Who is the ADO Air 20 Ultra 2026 folding electric bike best suited for?
The ADO Air 20 Ultra 2026 electric bike is the perfect solution for modern urban cyclists who commute daily and need a reliable, clean, and technologically advanced means of transport. Thanks to its quick folding, extremely compact dimensions (measuring only 885 x 670 x 510 mm when folded), and low weight of 22 kg, this bike is ideal for combining with public transport, storing in the office, or transporting in a car trunk. It is designed for riders with a height from 150 cm to 200 cm and supports a total load capacity of up to 120 kg. If you are looking for a bike without complex chain maintenance, with automatic shifting and smart safety features, this model is designed just for you.

Upgraded 2nd Gen BAFANG H730 motor with automatic shifting
The bike is powered by the latest, second-generation BAFANG H730 motor with a rated power of 250 W, which, compared to its predecessor, delivers an impressive 25% higher torque, now reaching 50 N·m. The motor features a smart automatic dual-speed transmission (Automatic dual speed transmission) that detects riding speed and incline, automatically shifting into the most appropriate gear. This provides extremely easy starting, more decisive acceleration at low speeds, and smooth tackling of steeper city hills without the need for manual shifting.

Smart IPS display with ultra-fast NFC unlocking
The new 2.4-inch IPS color display delivers an advanced user experience with NFC technology support. You can start the bike in just 1.7 seconds with a simple tap of an NFC card or smartphone – fast, secure, and completely without a traditional key. The display boasts a high water resistance rating of IPX7 and enables direct projection of navigation instructions (cast directions) straight from the ADO App mobile application, ensuring you can stay safely focused on the road.

Dual-sided torque sensor for an exceptionally natural assistance
Unlike conventional motion sensors, the ADO Air 20 Ultra 2026 uses a highly responsive Dual-Sided Torque Sensor. This system precisely measures your pedaling force from both the left and right sides, adjusting the level of electric assistance in real-time (you can choose between 3 assistance levels). The result is instantaneous motor responsiveness, exceptionally smooth acceleration, and optimal battery consumption, as the bike only uses energy when you truly need it.

Carbon Belt drive – quiet, clean, and maintenance-free
Forget about a dirty bike chain, rust, and constant oiling. The bike is equipped with an advanced Carbon Belt Drive. This drive system ensures virtually silent operation, requires no maintenance, and prevents dirt on your clothes. The lifespan of a carbon belt is significantly longer than that of a traditional metal chain, which means years of worry-free use.

Integrated aluminum frame and front suspension with lock-out
The bike's frame consists of a redesigned, one-piece aluminum frame (Integrated aluminum alloy frame), offering improved structural stability and a clean visual appearance with internal cable routing. For a smooth and comfortable ride over urban bumps, curbs, and cobblestones, the front shock absorber with lock-out capability (Lock-out Suspension fork) can be easily adjusted according to the riding surface.

AQS 2.0 quick-release system and versatile MIK rear rack
The new AQS 2.0 (ADO Quick Release System) allows you to install or remove a basket, bag, or backpack in seconds and without any tools. The included lightweight aluminum rear rack supports the established MIK standard and features a directly integrated rear reflector, reducing external cables and maintaining the bike's sleek lines.

Powerful battery with a long range of up to 100 km
A high-quality 37 V, 10 Ah battery is housed inside the seatpost, providing an outstanding range of up to 100 km on a single charge (actual range depends on rider weight, assistance level, terrain, and weather conditions). Charging time for a completely empty battery is just 4 to 6 hours, meaning the bike will be quickly ready for new journeys.

Premium safety: TEKTRO hydraulic disc brakes and 20" tires
Powerful hydraulic disc brakes from the renowned brand TEKTRO ensure safe and controlled stopping in all conditions. The bike is equipped with new, wider 20x2.0 inch tires with reflective sidewalls, which improve grip on wet surfaces and increase your night-time visibility. With an IPX6 water resistance rating for the entire bike, riding is safe even in heavier rain or storms.
