2. buy wider cranks
3. if there is enough room in frame to raise height of engine so the crank arm will pass just under pull start.
the last is a fairly easy solution if the frame will allow and you have a way to make an extended front engine mount.
the first two options are the most common since so many frames dont allow you to raise the engine enough to clear.
the "daimond shaped mountain bike and fixie road bike frame give plenty of room for raising the engine, but most cruiser frames don't.
The 29er might have room, but you'll just have to experiment to see what you have.
That's what I was wondering. Pull start would be nice, a lot easier on the drive parts and rear wheel. I just checked and the engine is low enough to hit them, I have about 5/8" clearance.
