Abstract
Kinetic Energy Recovery Systems (KERS) are widely used in motorsport and hybrid vehicles. Applying the same principle to a bicycle provides an accessible, purely mechanical demonstration of energy storage and recovery.
This project designs and fabricates a flywheel-based KERS for a standard bicycle. During braking, kinetic energy of the bicycle is transferred to a high-speed flywheel via a clutch or friction engagement. The stored rotational energy can later be returned to the rear wheel to assist acceleration, reducing rider effort after stops or on gentle climbs.
It is an ideal final-year Mechanical Engineering project covering energy conservation, rotational dynamics, clutch design and practical bicycle modification.
