Thanks for the compliments, yes the skate board wheel "machined down in diameter and notched for the chain" is very durable. I used some old MX handle bar clamps and a section of aluminum to make it. No more sucking into the spokes under compression braking. The rear chain ring is a 36 tooth, i run clip less pedals which help to get it rolling before i let the clutch out. I want to try taller gearing, since the motor will still pull this gearing easily. I'll post some better quality pics in a sec.
