Rad Power Bikes Radster

What the Rad Power Bikes Radster is built for

The Rad Power Bikes Radster is a commuter e-bike, built for daily rides to work, errands and city streets.

It has a 750 W hub motor, 100 Nm of torque and a top speed of 28 mph (45 km/h).

It carries a stated range of up to 65 miles (105 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 Rad Power Bikes Radster carries up to 320 lb (145 kg) including the rider.

In the United States the Rad Power Bikes Radster sells for $1,999, above the median of $1,499 across 230 commuter e-bikes with a US price, among the premium models.

Where the Rad Power Bikes Radster may be ridden

Rad Power Bikes Radster is sold as Class 1 (pedal assist only, up to 20 mph), Class 2 (throttle, up to 20 mph) and Class 3 (pedal assist up to 28 mph) under the three-class system most US states use. Class 3 e-bikes are kept off some bike paths and trails, and several states set a minimum age and require a helmet for them. Riders can switch between classes in the settings, and the class it is ridden in decides where it may go.

In the European Union and the United Kingdom an e-bike counts as a bicycle only within the pedelec limits; as specified, its 750 W motor is above the 250 W limit and its 28 mph (45 km/h) top speed is above the 25 km/h at which assistance must stop. 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.

Rad Power Bikes Radster safety certification

The brand states that the Rad Power Bikes Radster is certified to UL 2271 and UL 2849.

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

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.
