RIDER WEIGHT CALCULATION NOTE: Weight ranges are based on the rider's body weight plus approximately 6.8 kg of riding gear. Any heavy bike upgrades (such as an upgraded battery or controller) must also be added to this total rider weight. Very aggressive riders near the top of a weight bracket should consider sizing up and dropping the preload.
