GOTRAX Z4 Lite

What the GOTRAX Z4 Lite is built for

The GOTRAX Z4 Lite is a commuter e-bike, built for daily rides to work, errands and city streets.

It has a 350 W motor and a top speed of 20 mph (32 km/h).

It carries a 374 Wh battery and a stated range of up to 25 miles (40 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 GOTRAX Z4 Lite weighs 44 lb (20 kg) and carries up to 265 lb (120 kg) including the rider.

In the United States the GOTRAX Z4 Lite sells for $549, below the median of $1,499 across 230 commuter e-bikes with a US price, among the more affordable models. That is $1 per watt-hour of battery.

Where the GOTRAX Z4 Lite 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 350 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.

GOTRAX Z4 Lite safety certification

The brand states that the GOTRAX Z4 Lite is certified to UL 2849.

UL 2849 is the US safety standard for the whole electrical system of an e-bike: battery, charger, motor and controller tested together.

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.
