We’ve several rear sprocket options available for our customers to “great tune” their gas operated bicycle to achieve their desired optimal quickness/power gear ratio.
A note to remember: The larger the trunk sprocket, the slower the bike will go, but will have capacity to climb hills. Small 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.
