Driving with Dolphin E-bike is very easy and fun. If you ascend, select a comfortable, "allround" level gear: In front in the large chain wheel, in the back in sprocket 5 or 6 and start to pedal. The rest happens automatically.
With 60 pedal revolutions per minute (1 revolution/second) the motor achieves its full power.
The sensor constantly measures your pedalling frequency, and electronics regulates automatically the motor power. When you pedal, the motor always assists you - it is like power steering - the motor automatically doubles your power input.
