dc.description.abstract | This project presents the design and construction of a Kinetic Energy Recovery
System (KERS) integrated into a bicycle, utilizing a flywheel to enhance cycling
efficiency. The system captures kinetic energy during pedaling or braking and
releases it to assist with acceleration or uphill riding, reducing rider effort. A 3.27
kg cast iron flywheel (radius 0.075 m, moment of inertia 0.00919 kg/m²) was
mounted on a bicycle frame, connected via a pulley and chain drive system. Testing
on flat terrain with a 70 kg rider over 60 seconds showed the flywheel achieving
95–114 RPM at bicycle speeds of 10–12 km/h, storing 0.454–0.654 J of kinetic
energy. The system improved energy efficiency and ride smoothness but added
weight, impacting handling. Key advantages include reduced pedaling effort and
momentum maintenance, while limitations involve increased complexity and
reduced effectiveness on steep inclines. Applications include urban commuting and
recreational cycling, with future enhancements proposed using lighter materials and
gear integration for improved performance. | en_US |
