Off road bicycles, also known as mountain bikes, are built to endure tough terrain such as steep hills, rocky paths, and muddy tracks. However, there are various other synonyms for off road bicycles that cater to different types of terrains and styles of riding. For instance, gravel bikes are designed for speedy riding on unpaved roads and tracks. Fat tire bikes, as the name suggests, are built with wide tires that provide extra traction on soft and slippery terrains. Cyclocross bicycles are suited for racing and are built to handle various obstacles. Ultimately, while off road bicycles may be considered the overall term, there are numerous other subcategories that cater to different types of terrain and riding preferences.
