What is the term for a bicycle designed for off-road riding? The term is mountain bike.

A mountain bike is built for cycling on rough, unpaved terrain such as mountain trails, singletrack, fire roads, and rocky paths. Compared with a typical road bicycle, it commonly has wider knobby tires, stronger wheels, a broader handlebar, lower climbing gears, and more powerful brakes. Many modern designs also use a suspension fork, and some have rear suspension.

Mountain bikes developed from earlier experiments in off-road cycling, but the modern sport took shape in the late 1970s, particularly in California. Riders modified sturdy bikes for descending dirt roads and trails, helping create a purpose-built category. The discipline later divided into styles including cross-country, trail, enduro, downhill, and freeride.

Cyclocross is a racing discipline that uses lightweight bikes on mixed grass, mud, pavement, and obstacles; it is not the general name for every off-road bicycle. Hybrid bikes combine road and utility features, while road bikes are optimized for paved surfaces. A mountain bike can be ridden on pavement, but its rugged equipment usually makes it slower there than a road bike.
