Powered by a 250W rear hub motor (with peak output up to 500W), the X11 delivers smooth acceleration and reliable performance across mixed terrains. Its dual 48V 11.7Ah lithium-ion batteries (23.4Ah total capacity) provide an outstanding range of up to 150 km (93 miles) on pedal-assist mode, so you can ride further with fewer recharges.

The 20″ × 4.0″ fat tires ensure stability, traction, and comfort on roads, sand, snow, or gravel. The foldable aluminum alloy frame makes it easy to transport and store, while Shimano’s 7-speed gearing system lets you adapt seamlessly to city streets or hills.

Safety and comfort are prioritized with mechanical disc brakes for strong stopping power and a front suspension forkto absorb bumps. With a road-legal top speed of 25 km/h (15.5 mph) and an unlockable speed of up to 45 km/h (28 mph) for private use, the X11 balances compliance with excitement.
