I want to do a build this summer with my 15 year old son. Anything to get him away from video games and the internet. I've been trying to do some learning ahead of time. It seems the more I read, the more confused I get about how to proceed. I don't know if I should buy a full bike in a box kit, or custom frame made for motors. So much info. I really like the re-pop schwinn panther straight bar frame that is sold on eBay/Amazon. I'd love to do a board track style bike.
