    Motorized Bicycles

    Has anybody made a motorized bike with a Weed Wacker or Chainsaw motor?

    I've seen a few youtube videos of things like this, and it looks like a fun idea to do it with an old Peugeot I've had sitting in the basement.
    I'd like to hear from people who may have tried it, though.

    Friction drive with a roller seems extremely simple compared to rigging together a chain drive, but it also seems pretty abusive to the rear tire. Chain drive seems like it would go faster too, and I wonder if it would get better gas mileage.

    Anybody have experience with these things?

    I used to think adding a motor to a bike was killing the original idea. Then I lightened up a bit and learned that the earliest motorcycles got started by adding engines to bicycle frames. Now, I too am kicking around the idea of adding a motor to a bike I have laying around. Can't really offer advice since I have not done a project, only looked into it, so for more info I recommend checking out this page and reading through the various different posts, maybe even post your question there as well.

    Cool, thanks.
    I picked up a 39cc chainsaw for free off craigslist this afternoon.
    I'd like to go with a chain drive setup, but then I'd need an entire drivetrain for it and I don't have a spare bike for the parts. I guess I'll try friction drive, but I know I'm going to destroy the rear tire. It's in terrible condition already.
