The converting of my bicycle to a pedal assist electric started with the idea of putting to use an automotive power window motor I had for many years. I first made a list of my design objectives. Main objectives were: very easy to pedal or no pedaling, very low in cost, parts readily available, simple design to make and assemble.
I took this project as a fun engineering challenge. After making many various prototypes, the final design concept made pedaling almost effortless. I thank two of my grandchildren for making suggestions, comments and helped with some road testing.
After further testing, I thought why not share this design concept with others and write a book on how to convert a bicycle to a pedal assist electric. Pedal assist electric bicycles are not conserved motorized vehicles, so they can travel on pathways and trails marked "Motorized Vehicles Prohibited"
The step by step building instructions, detailed drawings, schematics, wiring diagrams, complete material lists and many pictures should greatly help in building and assembly. Hopefully you can make this a fun project as it was for me.
