Thanks for the welcome!
I'll do some looking into 2 and 4 cycle motors. Not quite sure which one would fit my application best. I have about 3 moderate hills to climb, but nothing to big.
The bike I now ride...well I won't be able to convert it...so I'll be looking at a completely new system.
My boss says I can only have one bike at a time. They take up to much room hanging from the rafters in the garage. (so she says) I guess she just doesn't understand how men operate.
