Abstract
An energy storage device includes, in combination: a vehicle adapted for propulsion via energy supplied by an operator, the vehicle having a pedal crank and a coaster brake hub disposed about an axle of a wheel of the vehicle, the pedal crank and the coaster brake hub being disposed in operable communication for transmitting energy from the pedal crank to the coaster brake hub and thence to the wheel; an energy storage device for selectively storing energy and selectively applying the stored energy, the energy storage device being disposed in operable communication with the pedal crank for transmitting energy from the pedal crank to the energy storage device for storage of the energy, and the energy storage device being disposed in operable communication with the coaster brake hub for selectively transmitting stored energy from the energy storage device to the coaster brake hub; and, combining device for differentially combining instant energy supplied by the operator and the energy storage device so that the energy applied to the coaster brake hub is essentially the sum of the instant energy supplied by the operator and the energy storage device.
