Bicycle Ingenuity

Long story, short... working on linear magnetically induced electrical circuit for powering whatever by attaching magnets to bike wheels. Sqeaky and I had some creative ideas and are working on the calculations. I need to test the lifting capacity of a variety of magnets at 2mm.

Has this been created before? Probably. Might we improve upon another patent? Possibly. Even if it is a catastrophic failure, due to complete miscalculations, flaws in design, or excessive cost, the project sounds fun.
