The following report is based on the use of regenerative electronic braking (REB) in an electric bicycle, for range and performance improvements. Due to the rising popularity of electric bicycles (E-Bikes) any technologies which can be developed to improve them have high potential for profitable business ventures. If any such technologies can be mass produced for a low cost, this could have even larger economic implications. Hence it was the aim of this research to develop a commercially viable prototype device which featured regenerative electronic braking with a supercapacitor, to improve range, braking/acceleration times, and battery life. The chosen design incorporated microprocessor control, brushed direct current (DC) motor drive, and combined supercapacitor/ Lithium-Ion energy storage. This electrical system was first connected to a stationary flywheel, to collect data during simulated braking events. Testing of this system indicated that the REB system did not achieve significant improvements in energy efficiency. The project was unable to continue to the construction of a prototype device due to limitations on budget and time constraints. However, the data collected from the flywheel connected system indicated that with minor adjustments and component optimization, the system could potentially achieve net gain in energy efficiency. It was concluded that although the initial research aim was not completely met, the results of the experiments identified various significant ways to improve E-Bike REB systems. Furthermore, this research proved that a lightweight, low volume REB system could be constructed at a low cost with commercially available components, indicating that a future product with a similar system could be financially viable.
