Powered bicycles


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.

    So then he just leaves his electric bike kit on the side of the road? It probably won’t get stolen.

    These are super popular in Holland. Easily a third of my local bike shop are electric bikes.

    Couldn’t you just charge it while pedaling?

    Far cheaper to buy a Sun EZ-TAD trike and a Bionics hub motor.

    Less than $1500.00 and a crapload less time spent making it.

    Electric bicycles are illegal in the state of New York.

  6. If electric bicycles are banned in New York, that is most unfortunate, and may be subject to change. China banned electric bikes in several cities, but has since repealed those bans.

    Small two-cycle internal combustion engines lack emission controls and are notorious noise polluters as well. An electric motor combined with advanced batteries (such as A123 lithium nanophosphate) can move a person very quietly using energy generated at an efficient central powerplant, wind farm or solar array.

    Ha! I’ve been in the planning stages of modifications to the XR-2 carbon fiber frame, and checking out hubmotors for sometime now. It’s fun, and not really too difficult. I think we’ll see more and more of these types of projects everywhere. If only carbon fiber were a little less messy to do…

    interest in making an engine with magnets but i dont have the money for the magnets also for the machine shop work.

    interesting invention, Mainly, that the built-in functions of bicycle were also saved

  12. I found your blog on google and read a few of your other posts. I just added you to my delicious. Keep up the good work. Look forward to reading more from you in the future.

    excellent post. to be honest i am not sure i fully understood your point completely. but, wanted to stop inand leave a note anyway. are you a freelance journalist by trade?, because your posts are really good.

  16. Darren says:

    Not the best looking bike but i guess it gets the job done. Wonder if the increase in weight is hard to handel if you get it up to any great speed?
