The electric bike revolution continues to accelerate, and ADO has unveiled its most advanced folding e-bike yet: the Air 20 Ultra, launched in April 2025. This groundbreaking model represents a significant leap forward in urban mobility technology, featuring the world’s first built-in BAFANG 3-speed hub in a foldable e-bike.
Revolutionary 3-Speed Automatic Technology
BAFANG H730 Motor Innovation
The heart of the ADO Air 20 Ultra lies in its sophisticated powertrain. Equipped with a BAFANG 3-speed internal automatic gear hub motor, the Air 20 Ultra intelligently shifts gears based on riding speed and terrain. This represents a significant advancement over traditional single-speed folding e-bikes and even the previous 2-speed systems.
With 24% more torque at low speeds compared to 2-speed systems, it ensures smooth starts, stronger climbs, and effortless cruising—without the need to manually shift. The automatic shifting points are precisely calibrated: first to second gear at 13 kph (8 mph), and second to third gear at 19 kph (11.8 mph).
Enhanced Performance Capabilities
The BAFANG 3-Speed Integrated Motor delivers 40 N.m of Torque Sensor for effortless climbs and rapid acceleration. Riders can seamlessly switch between Eco Mode for extended battery life during smooth commutes or activate Sport Mode for more demanding terrain. The BAFANG motor’s triple-speed system reduces effort by 24%, easing steep slopes and tough terrains.
Design and Portability Excellence
Lightweight Construction
One of the most impressive aspects of the Air 20 Ultra is its commitment to portability without sacrificing performance. The ADO Air 20 Ultra has features such as 19kg in weight, making it exceptionally manageable for urban commuters who need to carry their bike up stairs, onto public transport, or store it in compact spaces.
Quick-Fold Mechanism
Fold it flat in just 10 seconds and lift it with one hand. Weighing only 19kg+, the Air 20 Ultra fits into your car trunk, under your desk, or on a subway. One other change is that the Air 20 Ultra also gains a magnetic latch to secure the bike when folded – a small upgrade, but potentially a very useful one as it should make carrying the folded bike a good deal easier.
Advanced Features and Technology
Maintenance-Free Carbon Belt Drive
The Air 20 Ultra incorporates a sophisticated drive system that eliminates common maintenance headaches. Wave goodbye to greasy chains and noisy rides with our Carbon Belt Drive, built to last 30,000 KM without a single drop of oil. This maintenance-free system delivers whisper-quiet operation while ensuring longevity and reliability.
Smart Connectivity and Navigation
Modern riders demand connectivity, and the Air 20 Ultra delivers. Through the ADO Smart App, riders can monitor battery levels, navigate in real time, and track ride data such as distance and duration—all from their smartphone. The bike features an integrated IPS color display that provides real-time information and seamless app connectivity.
Safety and Comfort Enhancements
Safety hasn’t been overlooked in this design. The Air 20 Ultra comes equipped with hydraulic disc brakes, delivering responsive and powerful braking in all conditions—ensuring confidence and safety, whether cruising through city streets or navigating steep descents.
The upgraded front suspension fork is now made of aluminum, reducing overall weight by 450g while enhancing strength and shock absorption—ideal for tackling bumpy urban roads.
Battery Performance and Range
High-Capacity Power System
The Air 20 Ultra addresses range anxiety with its advanced battery technology. Unlock limitless freedom with our high-capacity portable battery, delivering an impressive 100 km range on a single charge. The upgraded 37V 10Ah battery provides up to 100km of assisted range, with an optional range extender offering an extra 60km for longer rides.
