Re: Herky jerky slow speed cruising?
If speed isn't your thing and you prefer just to putt around under 20mph... you may want to go with a bigger rear sprocket. I built a bike for a neighbor a couple years ago and he had no desire to go any faster then 15mph. He uses the bike in town only to go a few blocks to the Post Office to get his mail and he told me he would like it if he could peddle as little as possible and yet go as slow as possible under engine power. I mounted a 50 tooth sprocket on the rear and he can take off almost from a dead start... or perhaps a half peddle or so. His cruising speed I would guess is probably around 15mph and he can run probably as slow as 7 or 8mph without any bucking. Not much of a tour bike, but it works for him. You may want to play with your gearing some to see what works best for you.
