[Brad Graham] wrote in to let us know about his electric bike data dump over at atomiczombie.com, written just for us! Last we heard from [Brad] he was building some serious robots and freakishly tall tallbikes but since the weather has turned for the chilly its time to focus on indoor projects. Using a combination of robot parts, electrical conduit, and OEM bikes for the frames [Brad] takes us through several of his builds and all the various complications trying to drive the (often very powerful) electric motors. The builds range from scrapping motors and controllers to full blown drop in hub motor systems that can combine human and electric power. There is even an electric pusher cargo cart designed for a cooler, because beers are not going to haul themselves around.

Don’t forget to check out the AtomicZombie website for a ton of useful tips to chopping up bikes for your own mutant transpiration projects, we know we will. Thanks [Brad]!
