Touroll has launched the U3 Pro, a full-suspension electric mountain bike. The bike is available now for purchase directly from the official store.
Hub motor delivers 70 Nm torque
The U3 Pro uses a hub motor that delivers 70 Nm of torque. It is powered by a 720 Wh external battery that is not integrated into the frame. The bike features hydraulic disc brakes with 180 mm rotors and a seven-speed Shimano derailleur. It rolls on 29-inch by 2.4-inch tires. The suspension includes a rear shock and a suspension fork with lockout functionality.
