Mountain bikes are the most rugged type of bicycle. They were made to be cycled on mountains, steep inclines and the roughest of terrains. Very rarely will a mountain bike rider cycle on a paved road. The majority of mountain bike riders love cycling on narrow and unpaved trails resulting in greater wear and tear and forcing the manufacturers to have to design sturdier bicycles.
Mountain bike tyres are therefore fatter, bigger and made of a stronger type of rubber. This is great as it gives the cyclist better traction and allows the bicycle to run freely in both rough and smooth terrains.
Another significant feature that all mountain bikes have is a strong suspension system. It is now common for manufacturers to make bikes with both front and rear suspensions to help the cyclist withstand heavier bumps and thuds.
Depending on what type of suspension the bikes have, they are classified as soft tails, hard tails, fully rigid and dual suspension bicycles. The hard tail types have a front suspension fork while the rigid types have a rigid fork. The soft tail's rear suspension rests on the frame rather than pivots, and dual and full types have a front suspension fork and rear suspension. As well as this they have a rear shock absorber and linkage.
Mountain bikes made for cross country cycling are generally made of more lightweight and resilient components. They can weigh as less as 20 pounds with the heaviest you can buy weighing around 40 pounds. Enduro mountain bikes tend to be heavier than their cross country counterparts weighing on average between 30 and 35 pounds. They have better suspensions that are great for steep inclines or steering over hairpin bends.
Free ride mountain bikes are built of heavier materials. Unlike most other downhill bikes they are designed for easy pedaling. You will find them easy to maneuver around dangerous obstacles and steep turns. The flip side being they are not as efficient as cross country bikes due to them being heavier, weighing between 40 and 50 pounds.
Downhill Mountain bikes, while not as strong as free ride bicycles are most suitable for riding on downhill tracks and for racing. A downhill mountain bike's traction is better than most other types of mountain bike.
Trial bikes are meant for short distances and come without suspension. They do not have proper seat or vestigial pad and weigh less than most other bikes at around 15-20 pounds.
Urban and Street Mountain Bike's features vary in between the mountain bikes and trial bikes. They are very strong and come with between one and nine gears and a chain guide for the front and rear gears.
