This article will present one of the most well-known type of bicycle we know today. Unlike road bikes, mountain bikes are specifically designed for rough terrains. Almost all mountain bikes have common characteristics that offer great performance on rough terrains. They are quite heavier as compared to the road bicycle which gives them more durability. Mountain biking is roughly broken down into four categories: cross country, downhill, free ride, and trials/street riding. Each has differing levels of safety-consciousness with different types of bikes and riding gear.
For the purpose of shock absorption and additional traction, all bikes uses wide and knobby tires. In the past few years, full front and real suspension is gradually becoming a common feature of all mountain bikes. As you can see in the picture below that the handlebars has got bar ends. But today, lower handlebars or risen handlebars ( as in case of road bicycles) is becoming more popular in comparison with straight handlebars.
These bikes are available in different designs but it can be classified into various categories like
Hard Tail: with this design, the bike has no rear suspension. It only has front suspension.
Soft Tail: Unlike hard tail, it has some rear suspension and uses flex of the frame rather than pivots.
Fully Rigid: this type of bike has got no suspension. It is fully rigid and has a fixed gear.
Full Suspension: This type of bike has got both rear and front suspension and it also has got rear shock and linkage to move the rear wheel on pivots.
Most of the mountain bikes uses 559 mm wheels, although the measurements are not necessarily accurate. In some countries, mountain bikes have got 28 inch wheels like in Europe. For dirt jumping, 24 inch wheels are generally used. Sometimes both wheels of the bikes have got varying sizes to offer more variety and design.
Most of the these bikes have a 24 inch wheel for the purpose of dirt jumping. 24 inch wheels are also used for freeride bikes as well. But in these free rides, a 24 inch wheel is used as a rear wheel which makes the bicycle more maneuverable. Once, 29 inch wheels were used for Cross Country. However, these 29 inch tires are now becoming more common.
