The Subsystem Approach
The Subsystem Approach involves converting a bicycle that uses common bicycle hardware to an electric powered or power assisted vehicle. This approach to developing an eBike has at its core the idea that as many common and inexpensive bicycle parts should be used. The parts qualification is that it meet the need for the purpose, is commonly found at a bike store and is affordable for the scale of the project. The goal of the approach is interoperability of all the parts, keeping over all costs low (which opens the door to experimentation) and a degree of performance in a certain defined range.
