anybody know a company that sells bike motors? what are the average prices for these? Thanks.....

what you mean?

buy a motorbike if you want a bike with a motor

Try these dealers:
nycewheels.com
powerassist.com
evdeals.com

probably $100-200 for most 200-400W motors.

Much more if you go with a Heinzmann.

what about gas motors, is there a way to modify a chainsaw motor to power a bike?

My bike came with a free motor, but you get what you pay for.

It's hard to start in the morning.

Runs out of gas in the afternoon.

Emits noxious fumes after fueling.

Leaks water after a couple of hours.

And accumulates a foul smelling residue in the gas tank that I have to dump every few days.

i find if you pull the choke a few times if will get your motor running a bit quicker

hey do you know if you can get a motor for the front wheel? if so where and how much
