Motorbicycling 101

**Bikeguy Joe** · #1 07-30-2008, 02:39 PM

Here's a short primer to the Chinese built in-frame bicycle motor kit.

50-70cc piston ported (old, old school) two stroke.
Dry plate clutch (like a car), single speed transmission.
1-3 claimed horsepower.
25-45 mph top speed. (not recommened for the faint of heart)
Can be operated comfortably from 10-25 mph continuously.
100-150+ mpg!
Can be mounted on a suitable bicycle in 4-12 hours, depending on how thorough you are.
Adds about 20 lbs. to the bike.

Anybody want to add anything before I lock and sticky this thread?

Biking 101, once you build one you will most defiantly build more. Its a very addicting hobby because it is fairly cheap and a hole lot of fun , now if there was a way to make it legitimate thru out the entire USA we would see more and more of these MB around every town. We need more legislators in our corner

I figured about 28 pounds never truly measured.

I think one important point is that builders need to find a good, sturdy bike with strong wheels that are in good shape, I have read about a few accidents from hub and wheel failure and that could have been prevented. If you have an older bike, installing new bearings and greasing them well, and replacing rusted, fatigued spokes with heavier stainless spokes (have a pro do the job) can mean the difference between a safe ride and danger.

I would beware of super cheap department store bikes as well. Quality costs a little more and your future may depend on it.

Bravo Andy! Well said! I will say it again, these bikes were NOT designed to go as fast as we push them. Buy a good bike and use common sense when riding! Schwinn & Huffy are a good place to start.
