Default Re: Custom bicycle with scooter engine

It is quite simple to attach drive sprocket to any scooter wheel hub. To align the sprocket in center of the hub I have used a marker on a running engine to draw circles approximately where sprocket holes should go. Then I drilled them out one size bigger to leave some room for adjustment.

Final gear ratio is something like 28:38. With this ratio engine can rev up to 9000 RPM
