Abstract

The urban mobility is rapidly changing with electric bicycles (e-bikes) becoming the main solution to traffic congestion and air pollution. E-bikes combine electrical components with the design of traditional bicycles, offering an effortless ride with the option of pedaling manually. This study presents an e-bike design with a pinion-and-pulley drivetrain system that aims to optimize the torque and weight distribution. The research focuses on developing, testing, and openly sharing a prototype of a converted e-bike with this system. After driving tests, the estimated maximum distance for the prototype was 30.08 km on a single charge at full throttle.

Keywords:
