The moped shape Super73 is known for, fully rigid and single speed, on mismatched VEE LZRD tyres: 4.5 inch front and 5 inch rear. TEKTRO MECHANICAL brakes rather than hydraulic, which is unusual at $2,395 and on a bike rated to 325 lb. 480Wh is the smallest pack on this site, and the 25 to 35 mile claim is honest about being a throttle-only figure, which most makers are not. ONE OF ONLY THREE SUPER73 MODELS WITH A CADENCE SENSOR: their own guide at eu.super73.com/blogs/guides/cadence-and-torque-sensor says the Z-MIAMI, ZG and ZX are cadence and the rest are torque, and no product page states it at all. Super73 say the battery is "UL2271 Compliant", which is not the same claim as certified, and nothing about the whole system.

| 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.
