The bicycle is constructed with a 6061 aluminum alloy folding frame, featuring a low-step design for easy mounting. It’s suitable for individuals between 152 cm and 188 cm in height and can support up to 150 kg. The bike weighs 26.5 kg and includes a rear rack capable of carrying up to 15 kg. It also holds CE EN15194 certification from TUV.
Recommended for various terrains including paved roads, gravel paths, sandy beaches, grass, rural roads, and paved trails, the ENGWE O20 Boost offers different levels of water resistance for its components: IPX7 for wiring, IPX6 for the display and lights, IPX5 for the motor and controller, and IPX4 for the battery case.
At its core, the O20 Boost is powered by a 250W rear hub motor, compliant with European regulations, enabling a maximum assisted speed of 25 km/h. It features a torque sensor providing up to 75 Nm of torque for a responsive riding experience. A “Boost” function allows for temporary maximum assistance. The bike offers five levels of pedal assist (PAS), controlled via a 3.5-inch color LCD screen.
The drivetrain consists of a Shimano Altus RD-M310 8-speed rear derailleur and a Shimano SL-M315-8R shifter. It has a 48-tooth single chainring and an 8-speed cassette with a range of 13-28 teeth, coupled with an anti-rust chain.
For rider comfort and terrain handling, the bike is equipped with a 50 mm hydraulic front fork with adjustable lockout. The wheels are 20-inch with double-walled aluminum rims and puncture-resistant urban hybrid tires (20 x 2.125 inches). Braking is handled by hydraulic disc brakes with 160 mm rotors on both the front and rear wheels.
A significant feature is the removable 720 Wh (48V – 15 Ah) battery, utilizing LG 21700 cells and a BMS for reliability. This battery is advertised to provide a range of up to 141 km in PAS 1 mode, 108 km in PAS 3, and 80 km in PAS 5. The included 54.6V – 4A charger fully recharges the battery in approximately 3.5 hours.
The folded dimensions of the bike are 88 x 52.5 x 85 cm (height, length, width), significantly reducing its footprint for storage and transport. When unfolded, it measures 154 x 113-123 cm (length x height).
Additional features include the ENGWE app connectivity via Bluetooth, a 40 Lux front light and K-Mark certified rear light, and an Mtag fit locator.
