What the Rad Power Bikes RadExpand 5 Plus is built for

The Rad Power Bikes RadExpand 5 Plus is a folding e-bike that packs down to fit a car boot, an apartment or a train.

It has a 750 W hub motor, 64 Nm of torque and a top speed of 20 mph (32 km/h).

It carries a stated range of up to 60 miles (97 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 RadExpand 5 Plus carries up to 315 lb (143 kg) including the rider, has front suspension and uses a torque sensor, so the motor responds to how hard you pedal.

In the United States the Rad Power Bikes RadExpand 5 Plus sells for $1,899, above the median of $800 across 24 folding e-bikes with a US price, among the premium models.

Where the Rad Power Bikes RadExpand 5 Plus may be ridden

Rad Power Bikes RadExpand 5 Plus is sold as Class 2 (throttle, up to 20 mph) under the three-class system most US states use.

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 20 mph (32 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.
