The smallest Super73: a 28 inch seat and a recommended rider height starting at 4 feet 6 inches, which is the shortest rider this site can point anyone to. It is also the lightest at 59 lb, and the only Super73 on even tyres front and rear (VEE Trooper 4 inch) rather than the mismatched 4.5/5 setup. Mechanical brakes, fully rigid, single speed. One of the three models Super73 put a cadence sensor in. Brakes are Tektro, 2 piston, mechanical; suspension is rigid; seat height 28 inches; charge time 5 hrs; horn not fitted. SENSOR SOURCE: Super73 publish the sensor type on no product page. Their own guide at https://eu.super73.com/blogs/guides/cadence-and-torque-sensor says "The SUPER73 Z-MIAMI, ZG, and ZX are equipped with a cadence sensor. The rest of the SUPER73 models have a torque sensors." Super73 describe the pack as "UL2271 Compliant", which is a battery claim and a weaker word than certified; there is no UL 2849 system claim.

| As the maker states it | Batteries described as UL 2271 compliant (compliant, not certified) |
Safety certification: UL 2271: battery only. Super73 states: “Batteries described as UL 2271 compliant (compliant, not certified)” (source). That is the manufacturer’s own claim, not something we verified, you can check a specific model in UL’s Product iQ database. Why this matters.
