One question I have is why the Strong GT-S210 gets mileages of >50km with a similair battery pack of 36v 12ah and it is a much heavier bike. Is it that much more efficient? Do the large tires give it that much less rolling resistance? Or do they discharge their batteries to the point where they offer no assist at all?
