GOTRAX Shift S4 Power-Assisted

What the GOTRAX Shift S4 Power-Assisted is built for

The GOTRAX Shift S4 Power-Assisted 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 16 mph (25 km/h).

It carries a 281 Wh removable battery and a stated range of up to 28 miles (45 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 Shift S4 Power-Assisted carries up to 265 lb (120 kg) including the rider.

In the United States the GOTRAX Shift S4 Power-Assisted sells for $550, below the median of $1,499 across 230 commuter e-bikes with a US price, among the more affordable models. That is $2 per watt-hour of battery.

Where the GOTRAX Shift S4 Power-Assisted 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. 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 Shift S4 Power-Assisted safety certification

The brand states that the GOTRAX Shift S4 Power-Assisted is certified to UL 2272.

UL 2272 is the US safety standard for the electrical system of personal e-mobility devices such as electric scooters.

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.
