Jetson J8

What the Jetson J8 is built for

The Jetson J8 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 battery and a stated range of up to 30 miles (48 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 J8 weighs 43 lb (19.5 kg) and carries up to 260 lb (118 kg) including the rider.

In the United States the Jetson J8 sells for $1,300, close to the median of $1,499 across 230 commuter e-bikes with a US price. That is $5 per watt-hour of battery.

Where the Jetson J8 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 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 J8 safety certification

The brand's listing for the Jetson J8 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.
