DIY eBike

The goal of this XProject was to create an affordable e-bike conversion tutorial for commuters and bike hobbyists that can be done within a weekend. The main objective was to design a mount that allows a DIY e-bike to receive power from a commercial power tool battery. More specifically, the mount was designed to accept the RYOBI 40-Volt lithium-ion high-capacity battery. The intentions for this scope of design were as follows:

  • Employ the economies of scale that are soon to come for lithium-ion batteries​
  • Take advantage of the safety features already incorporated in the battery
  • Provide a battery solution for an E-bike that is easy to source and replace

The team worked over the course of a semester with their sponsor and projects coordinators to develop engineering solutions for battery mounting, electronics and connectors, motor install, and integration.
