The invention discloses a cross-country motorcycle which comprises a rear wheel, a rear axle, a front wheel and a rack, a hub is arranged on the rear wheel, the hub is rotationally arranged on the rack through the rear axle, a plurality of power assisting parts used for increasing the contact area between the rear wheel and the ground are arranged on the hub, and contraction parts matched with the power assisting parts are arranged on the rear axle, so that the power assisting parts are tightened for preventing contact with ground. According to the cross-country motorcycle power assisting device, the trafficability of a cross-country motorcycle on a severe road section can be enhanced, the road holding force of the motorcycle during starting is enhanced, stable running of rear wheels is guaranteed, and meanwhile different driving modes are provided by detecting whether the motorcycle is in a running state through wind resistance during running.
Description
technical field [0001] The invention relates to the technical field of motorcycles, in particular to an off-road motorcycle. Background technique [0002] Off-road motorcycle is a commonly used off-road tool, which has excellent field passing performance and is a popular vehicle for people to travel in the field. Ordinary off-road motorcycles are usually rear-wheel drive, and their performance through complex road surfaces is enhanced according to the friction between the rear wheels and the ground. However, in order to adapt to more complex and difficult road sections, this type of pure rear-drive off-road motorcycle usually cannot meet the off-road requirements, and when passing through muddy road sections and potholes, it will make driving difficult due to rear wheel slippage, reducing off-road performance. Contents of the invention [0003] The invention provides an off-road motorcycle aiming at the deficiencies in the prior art. [0004] In order to solve the above-...
