Jetson Fatboy

What the Jetson Fatboy is built for

The Jetson Fatboy is a commuter e-bike, built for daily rides to work, errands and city streets.

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

It carries a 576 Wh removable battery and a stated range of up to 50 miles (80 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 Jetson Fatboy weighs 114 lb (51.5 kg) and carries up to 441 lb (200 kg) including the rider.

In the United States the Jetson Fatboy sells for $1,800, above the median of $1,499 across 230 commuter e-bikes with a US price, among the premium models. That is $3 per watt-hour of battery.

Where the Jetson Fatboy 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.

Jetson Fatboy safety certification

The brand's listing for the Jetson Fatboy does not state a UL 2849 or EN 15194 certification. New York City allows only e-bikes certified to UL 2849 to be sold or rented there, and California requires certified batteries from 2026; ask the seller for the certificate before buying.
