We’ve started to noticing a lot of commercial electric bikes on the street. Last year we looked at an electric trike project, after the break find out what people have been up to lately with similar projects.
[Jeff Radtke] and [Hans Noeldner] are two engineers who put together a self-contained electric powered bicycle wheel. The unit can attach to just about any bike and covers around 10-20 miles on each charge. By using standard Dewalt 36V battery packs, new batteries can be easily swapped out when needed. Overall you are getting about 1HP with this setup and maximum speed of 28MPH.
Inventor [Eric Peltzer] recently announced his electric bike project was going open source. After sharing his experience through on his website for years he is now looking for contributors to help develop and monetize the project.
[Frankg] lost his license some time ago so he built himself another form of transportation. He candidly takes us through the building and tweaking of his electric bike conversion through his website. He even takes us through the process of how not to build an electric bike as well.
