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?
