I'm posting this because some on the net are claiming 35mph as top speed
on these 4-stroke kits equipped with belt drives.
Assuming the belt drives are 5:1, here's the calculated top speed on a 26 inch bike:
44T rear sprocket, 10T drive sprocket = 25 mph
41 rear sprocket, 10T drive sprocket = 26 mph
36T rear, 10T drive = 30 mph
I see a friction drive as a better option, powered by a GX50 Honda.
With a staton drive equipped with a 1.5 inch roller, top speed is 31mph.
All the power is applied to the wheel with no power losses caused by
transmissions or vibrating chains.
For more speed, and noise, a user can select a 2 stroke Zenoah G43L capable of 12,000 rpm.
At 10,500 rpm a friction drive Zenoah with a 1.34 inch roller, top speed is 41mph.

The fricton drive is extremely attractive for motorizing a bicycle, and capable of mounting
to any bike.
