An off-road electric bike, also known as an electric mountain bike, is a type of bicycle designed for off-road adventures with the assistance of an electric motor. It is similar to a traditional mountain bike in terms of its features, such as suspension, wide tires, and rugged frame, but it also has a motor and a battery to help the rider tackle more challenging terrain.

The electric motor provides additional power to the pedals, allowing the rider to climb hills more easily, cover longer distances, and ride at higher speeds on rough terrain. The battery is usually mounted on the bike's frame and provides power to the motor.

Off-road electric bikes come in various designs, including hardtail and full-suspension models, with different power and battery capacity levels. They are typically more expensive than traditional mountain bikes due to the added cost of the motor and battery. Still, they can be a great investment for those who enjoy off-road adventures and want to cover more ground with less effort.
