The Onex bike is here and put together. The 4G motor is on its way from BE.com. The mounting kit picture shows me a sprocket and pedal extension shaft. Can I use the extension shaft and stock sprocket or must I use the kit sprocket? I guess this motor is too wide to clear the pedals? Has anyone put together a HS 49 cc motor with a 4G t drive using the Genesis Onex? Is there a pedal clearance problem?
