An electric bike is an exceptionally convenient form of transportation. It's simple quiet and quick. Although its weight is more than a regular bike's.
The TORNADO e-bikes can be pedaled as a conventional bicycle when the power is turned "off".
Riding the e-bike with power is similar to riding a moped when the speed can be simply increased and decreased by twisting the throttle on the handlebar.
Additional to the throttled mode some e-bikes can be used in "pedal-activated power support" mode. In this pedal activated mode the power rate of the motor depends on the pedal torque and pedal speed and it is controlled by a highly developed computer unit. Riding the electric-bike in this mode is like pedalling a regular bike downhill or in backwind.
