As a full-size off-road bike, the torque is one of the most important core specifications. Due to the electric motor, the torque of Storm Bee reaches amazing 520 N·m! The powerful torque output brings crazy accelerating ability. 0-50km/h needs 1.8 seconds, 0-80km/h needs 3.6 seconds, and the top speed can reach over 110km/h. The Storm Bee’s power of 22.5KW is flat to that of 250cc fuel bikes, but the torque of 520 N·m can make the accelerating performance almost be equal to the 600cc motorcycles! In addition, due to Storm Bee does not have the complicated clutch shift control, riders just twist the right handlebar to the end to enjoy the terrifying acceleration feeling like tearing the air.

Of course, it can run fast and also be to stop.
