Jetson Otto

What the Jetson Otto is built for

The Jetson Otto is an electric mountain bike for trails and off-road riding.

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

It carries a 499 Wh removable battery and a stated range of up to 37 miles (60 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 Otto weighs 70 lb (31.8 kg), carries up to 300 lb (136 kg) including the rider, has full suspension and is rated IPX5 against water.

In the United States the Jetson Otto sells for $2,000, above the median of $1,299 across 22 electric mountain bikes with a US price, among the premium models. That is $4 per watt-hour of battery.

Where the Jetson Otto 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 Otto safety certification

The brand's listing for the Jetson Otto 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.
