New motorized bicycle project

[prodigit]

Never had that happen, but then again, all things are possible.
The thing is that a bicycle frame is much more fragile than a scooter frame.
It is possible to torque, or break the frame, or wheel parts from the engine power.

Most kits are only one gear. The guy is lucky to have several. I wish I had several too!
I'm limited to one gear, where I need quite some pedaling to get enough speed to jumpstart the engine; a price I'd probably have to pay for the higher MPG values.

Another thing, they mentioned that a lot of these bike engines have bad counter balances in them, causing excessive vibration. some people get rid of the vibration by drilling small holes in them, or soldering onto existing metal to counter the weight difference.
Without it some people say the vibrations are a lot...
I hope it's going to work out though...

Are you thinking of putting your engine on a metal/rubber/wooden block, or mount it straight to the frame?
