Parts and upgrades for the Altis Powersports Sigma: brake pads and rotors, footpegs, seat covers, rear shocks, brake levers and the universal e-moto range of bars, grips, 520 chains, tires, tubes and maintenance gear. The Sigma runs a high-voltage 97.2V system and a 520H chain, so chain, sprocket and brake fitment is where to pay attention.
