Foldable Electric Bike Answered

i want to build an electric bike and i was thinking it would be really cool if it could fold down and maybe fit in a backpack or a brief case of some sort. that would be so cool.


yeah but i don't want to spend a couple thousand dollars and that would be fun but it would be better if it was cheaper

 Part of imagineering is to research what is already out there.  Reverse engineer some things as they may already worked out some of the kinks in the application of the product.  You would probably need to know how to weld or at least braze metals, work with composites like carbon fiber or fiberglass. or even wood and bamboo.  Then you need to know about gears, and motors and coupling the power sources.

And that is the fun part of DIY without $$$.  Good luck.
