Abstract
The present invention relates to an energy transfer system, in particular in the form of an energy efficient wheel for use with a vehicle such as a bicycle, which energy transfer system is operable to convert potential energy in the form of the load applied by the weight of the person on the vehicle into kinetic energy in the form of driving torque applied to the wheel, the system including an inner hub and an outer hub eccentrically coupled to the inner hub, in addition to a rim connected to the outer hub via an array of spokes, wherein an actuator comprising a pair of flanges extends radially outwardly from the inner hub and an array of lever arms are hingedly mounted to the outer hub and engaged by the actuator such as to be hingedly displaceable by the actuator in response to relative movement between the inner and outer hubs, and a spring captured between each lever arm and one of the spokes.
