The Touroll U1 Mountain Electric Bike is built for riders who seek comfort, endurance, and smooth riding across different terrains. Designed in two frame options (26” and 29”), the U1 provides versatile choices for both commuting and outdoor adventures.
Powered by a 36V 468Wh lithium battery and a 350W hub motor, the U1 offers a maximum range of up to 65 km in pedal-assist mode, making it a reliable partner for both short daily rides and long weekend explorations. With disc brakes, e-brake safety features, and a mechanical shock absorber, it ensures stability and control across city streets and countryside trails.
The U1 comes equipped with a high-definition display, providing real-time riding data such as speed, battery status, assist levels, and walk mode. Combined with three pedal-assist levels, riders can choose between leisurely cruising, efficient commuting, or more power-assisted riding when needed.
