This mountain bike has a 21-speed gearbox system, and the correct use of the gearbox can cope with complicated road conditions and weather such flat roads, up and down slopes, dirt roads, and wind. It is faster and less labor-saving than ordinary bicycles.
For long-distance riding, the governor must be replaced in time to give full play to the advantages of mountain bikes. If you feel that pedaling is too easy, you can to high speed. Conversely, if riding feels too difficult to pedal, you can to a low gear.
