Folding Electric Bike ADO Air 20 Ultra 2026
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 and extremely compact dimensions (folded, it measures only 885 x 670 x 510 mm) 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 heights 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 complicated chain maintenance, with automatic shifting and smart safety features, this model is designed just for you.

Upgraded BAFANG H730 2nd Generation Motor with Automatic Shifting
The bike is powered by the latest, second generation BAFANG H730 motor with a nominal power of 250 W, which, compared to its predecessor, delivers a 25% higher torque, now at 50 N·m. The motor features a smart automatic dual-speed transmission that detects riding speed and incline, automatically shifting to the most suitable gear. This allows for extremely easy starts, stronger acceleration at low speeds, and smooth conquering of steeper city climbs without the need for manual shifting.

Smart IPS Display with Ultra-Fast NFC Unlock
The new 2.4-inch IPS color display offers an advanced user experience with NFC technology support. You can start the bike in a mere 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 level of water protection IPX7 and allows for direct projection of navigation directions (cast directions) directly from the ADO App mobile application, ensuring safe focus on the road ahead.

Dual-Sided Torque Sensor for 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 and adjusts the level of electric assistance in real-time (you can choose between 3 levels of assistance). The result is instant motor response, exceptionally smooth acceleration, and optimal battery consumption, as the bike only uses energy when you truly need it.

Carbon Belt Drive – Silent, Clean, and Maintenance-Free
Forget about dirty bike chains, rust, and constant oiling. The bike is equipped with an advanced Carbon Belt Drive. This drive system ensures almost silent operation, requires no maintenance, and prevents dirt on your clothes. The lifespan of a carbon belt is significantly longer than a classic metal chain, meaning many years of worry-free use.

Integrated Aluminum Frame and Front Suspension with Lockout
The bike's frame consists of a redesigned, one-piece aluminum alloy 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 a lockout option (Lock-out Suspension fork) can be easily adjusted to suit the riding surface.

Fast AQS 2.0 System and Versatile MIK Rack
The new AQS 2.0 (ADO Quick Release System) allows you to attach or remove a basket, bag, or backpack in a few seconds without any tools. The included lightweight aluminum rear rack supports the established MIK standard and has a directly integrated rear reflector, which reduces the number of external cables and maintains the elegant line of the bike.

Powerful Battery with Long Range up to 100 km
A high-quality battery with a voltage of 37 V and a capacity of 10 Ah is located in the seat post, providing an exceptional range of up to 100 km on a single charge (actual range depends on rider's weight, assistance level, terrain, and weather conditions). The charging time for an empty battery is only 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 tires measuring 20x2.0 inches with reflective sidewalls, which improve grip on wet surfaces and increase your visibility at night. With a water protection rating of IPX6 for the entire bike, riding is safe even in heavy rain or storms.
