Overview: Surface 604 Boar Hunter

The Surface 604 Boar Hunter is an electric mountain bike designed for off-road adventures. It is available in the United States and Canada and was released in 2020. The bike features a powerful motor that can provide pedal assist up to 20mph, as well as a throttle on demand option. With a forward body position, the Boar Hunter is recommended for trail, sand and snow, mountain, and bikepacking use. The bike is classified as a Class 1 electric bike, which means that the motor only provides assistance when the rider is pedaling. However, it also has a Class 2 throttle on demand option, which allows the rider to control the motor without pedaling. The bike is also classified as a Class 4 moped or motorcycle, which means that it is capable of speeds above 28mph and may require a license or registration in some areas. The Surface 604 Boar Hunter has a starting price of $2,499, with an optional 14ah battery upgrade for $200 more. The bike comes with a 1 year comprehensive warranty and a 3 year frame warranty.
