I hope you can find some answers here!!

Q: What are the laws regarding motorized bicycles?

A: There is a lot of grey area. In my experience, as long as you are riding safely and your motor is not too loud, the police will give you no trouble at all. Wearing a helmet and having working head and tail lights is a plus. Check your state vehicle code to see the specifics or the Motorized Bicycle Laws section right here on this site.

Q: How fast does it go?

A: My motorized bike can get up to ~26MPH on flat ground before it tops out. This max speed can change depending on motor size, wheel size and sprocket size.

Q: Where can I get a kit, and how much does it cost?

A: I have found that you can get the best deals at or You can get a kit with everything you need anywhere from $170 to $220.

Q: How long will it take to install?

A: Depending on the bike and your mechanical know-how, it could take you from 2 hours up to 10 hours.

Q: What bikes will this kit fit on?

A: You can find a kit for almost any bike. The kit that I have on my bike will typically only fit hard-tail (no rear suspension) bikes with a large enough frame.

Q: Do I have to drill holes in my bike to get it on? Can I take it off later if I decide I don’t like it?

A: If your bicycle frame tubes are too fat, you might have to drill a hole in the frame. Other than that your bicycle should not have to be permanently modified to fit the kit on properly. The engine puts out a lot of vibration, so tightening up all the components every once in a while is a good idea. My first bike (My Blue Junker) fell apart after 4 months as it was abused, and a pretty crappy bike to begin with. I bought a new bicycle, and I was able to successfully take all the engine components off the blue Junker and mount them cleanly on the new bike (My Green Machine) with no problems.

Q: How do you start and drive the bike?

A: There are 2 extra (meaning not on a standard non-motorized bicycle) controls that come with the engine. The first is a throttle, and the second is a clutch. All the clutch does is connect or disconnect the engine from the rear wheel. In order to start the bike, you pull the clutch in (to disconnect the engine from the wheels), and you start pedaling to build up momentum, and finally, you release the clutch to transfer momentum into the engine, thus starting it.

Q: Do you ever burn your legs on the motor?

A: Personally, I have never burnt myself while riding. I have, however, burnt my hands while foolishly trying to lock up my bike while the motor was still hot.

Q: I still have unanswered questions! Where do I get answers?

A: Right here on the forum.
