2. I know the rough idea about this topic. I want some more information about this topic.

3. I am explaining the working of this project:
i. First the battery is charged with external current.
ii. with the help of battery the motor is run.
iii. The rotating shaft of motor is connected to the rear wheels.
Additional process
iv.The alternater is connected to rear shaft which is connected to rear wheels by chain or belt drive.
v. When the motor is run with help of battery the rear shaft is rotated & the alternater connected to the shaft is started & so the electric current is generated .
vi. This current is again connected to the main battery.
vii. so ,the main battery is again recharged . And the efficiency of this bike is increased.
