Default Re: Avid cyclist looking to build 1st motor bike

Thanks for the replies.

I have a friend who welds, so a custom drivetrain is possible.

USA made would be nice but if it's going to be a PITA, I am open to other options.

Currently, I am looking at picking up a single-speed steel frame mountain bike with disc brakes.

What should I be considering when measuring the frame, chainline or other geometries? Can any frame-mounted motor be made to fit with slight adjustments or should I be looking at a specific type of bike to make mounting the motor easier? From my initial research it looks like most motors are made to fit 26 inch wheelsize frames.

Also, what are the power/reliability/quality/exhaust smell differences between 2 and 4 stroke motors?
