We’ve several rear sprocket possibilities for our clients to “fine tune” their gas operated bicycle to accomplish their desired optimal speed/power gear ratio.
A note to remember: The larger the trunk sprocket, the slower the bike will proceed, but will have power to climb hills. The smaller the trunk sprocket, the quicker the bike will proceed, but will climb hills much less successfully. You are trading power for velocity or vice versa.
