The ZX is the larger version of our Z1 and features a lighter aircraft-grade aluminum frame and a larger removable battery. With a brand new redesigned seat, improved ergonomics and a more upright riding position, the ZX stands as one of SUPER73’s most comfortable bikes to date.*Battery range estimates depend on conditions such as rider weight, speed, temperature, wind, tire pressure, terrain, incline, etc. Mileage may vary.
