Default Re: what did you do to your motorized bicycle today?

Not today, but yesterday...
Took a quick run to test out an experiment. It was 20 degrees F. and windy. Fun! But that was supposed to be the nicest day we're gonna have for another week or so.

So far my weed wacker friction drives have used springs to pull the motor/roller down onto the tire.
On this new design, I rigged a lever that locks the roller up off the tire or down into the tire. Worked perfect first time! Just the right amount of force to not slip. I wasn't looking forward to hopping on and off the bike to fine-tune things with freezing fingers.

I've got pictures, but since it was a prototype (from plywood), you would probably consider it pretty cheesy looking.
