SUPER73-ZX

What the SUPER73-ZX is built for

The SUPER73-ZX is a moped-style e-bike with a bench seat and motorbike looks.

It has a 500 W motor and a top speed of 20 mph (32 km/h).

It carries a 480 Wh battery and a stated range of up to 35 miles (56 km) on a charge. Real-world range is usually lower than the rated figure: it falls with throttle use, hills, cold weather, rider weight and higher assist levels.

The SUPER73-ZX weighs 62 lb (28.1 kg) and carries up to 324 lb (147 kg) including the rider.

In the United States the SUPER73-ZX sells for $2,395, close to the median of $2,695 across 20 moped-style e-bikes with a US price. That is $5 per watt-hour of battery.

Where the SUPER73-ZX may be ridden

In the European Union and the United Kingdom an e-bike counts as a bicycle only within the pedelec limits; as specified, its 500 W motor is above the 250 W limit, its 20 mph (32 km/h) top speed is above the 25 km/h at which assistance must stop and its throttle moves it without pedalling, which the pedelec rules allow only as start-up help at walking pace. A model above those limits is treated as a moped there, with type approval, registration and insurance, unless the brand sells a version set to the European limits.

SUPER73-ZX safety certification

The brand states that the SUPER73-ZX is certified to UL 2271.

UL 2271 is the US safety standard for the battery pack of a light electric vehicle.

New York City allows only e-bikes certified to UL 2849, with batteries certified to UL 2271, to be sold or rented there; California requires e-bike batteries to meet UL 2849 or EN 15194 from 2026.
