A power assisting device for a bicycle generally including an electric generator, an electric motor and a rheostat. The rheostat includes a mount having a first insert and a second insert. Both inserts include upper and lower apertures. Each upper aperture includes a contact, where in a first position the contacts are in contact with one another, and in a second position the contacts are not. The first insert is attached to the brake lever. Applying the front brakes with the braking lever causes the first insert to move from the first position to the second position. The generator is electrically connected to the upper aperture of the first insert, and the motor is electrically connected to the upper aperture of the second insert. When the braking system is not applied, the inserts are in the first position and the contacts are in contact causing an electrical connection between the rheostat, the generator and the motor. When the bicycle rider applies the bicycle's front brakes, the first insert moves from the first position to the second position. In the second position, the contacts are no longer in contact, breaking the electrical connection between the motor and generator.
