The SUPER73-ZX is the newest addition to the Z-series line and brings one of SUPER73’s most beloved form factors into the next generation with updated electronics, a lighter 6061-T6 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 and can accommodate riding with a second passenger.
