Curious if you are satisified with the gearing on the Hai Trekking. Mine has the yamaha with the dual front sprocket. The top end is lacking. I find myself riding in the top gear most of the time, sure the motor cuts out at 20 mph but that doesn’t mean the rider cant push it faster. Especially if had more top end. Curious if anyone has modified their front sprocket or cassette to give it more top end.
