Trying to find a few more m.p.h., but I’m about out of drive myself for the day. Went from a 50T rear sprocket, to a 47T, to a 45T (pictured), and have a 42T on order. Don’t know if the two-three-oh will pull the big gear, but I’m trying to get at least 55 out of it without completely screaming the motor.
Nothing better than having the right tools for the job…(thanks Mike D.).

Watch out for the cattle trucks and beer bottles coming out of the windows of the busses!!!
45 MPH? Sounds like a moped my brother once had. Good luck BT!
Yes, I know…but this moped I’ll have to ride in the day…not after dark…like your bro.
