What the isinwheel U8 Ultra is built for

The isinwheel U8 Ultra is a commuter e-bike, built for daily rides to work, errands and city streets.

It has a 1,500 W motor and a top speed of 28 mph (45 km/h).

It carries a 864 Wh removable battery and a stated range of up to 105 miles (169 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 isinwheel U8 Ultra weighs 82 lb (37 kg), carries up to 331 lb (150 kg) including the rider, has front suspension and is rated IP65 against water.

In the United States the isinwheel U8 Ultra sells for $930, below the median of $1,499 across 230 commuter e-bikes with a US price, among the more affordable models. That is $1 per watt-hour of battery.

Where the isinwheel U8 Ultra may be ridden

isinwheel U8 Ultra is sold as 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.

In the European Union and the United Kingdom an e-bike counts as a bicycle only within the pedelec limits; as specified, its 1,500 W motor is above the 250 W limit, its 28 mph (45 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.
