When most people think of mountain biking, they think of climbing up to the top of a mountain and then riding down it again. However, there are plenty of opportunities for the fat-tire enthusiast, and the disciplines are growing every year as riders find new ways to challenge themselves.

Below is just a brief list of some of the biking disciplines associated with mountain biking. For each discipline, you'll be able to find bikes especially made for the different challenges they present, and the different skills needed.

1. BMX

BMX stands for bicycle motocross. The cycles used are specially designed to operate on a dirt track: a groomed racecourse made up of various jumps, banked and flat corners, and therefore have small wheel diameters - 20-inches, and fat tires. The sport began in California in the late 1960s, as young boys began emulating their motocross heroes, and is now popular around the world.

2. Cross country

Just as its name implies, fat-tire enthusiasts bike across country - specifically hilly country to test the rider's endurance.

3. Cyclo cross

A cyclo cross bike is a road bike with powerful brakes, extra mud clearance, and tires that aren't exactly fat but do have knobs on. These bikes are used for Cyclo cross racing, a sport which began in Europe, as off-season training for road racers. The courses are a mile long, and are partly paved and partly mud-soaked to give the rider all kinds of challenges. Also on the course are a certain number of barricades, forcing the rider to dismount and carry his bike over them. Everyone races flat out.

4. Dirt jumping

The idea with dirt jumping is not so much the jumping but what tricks the rider can do while he is air borne. The idea is not to get around the course as fast as possible but to have the most air time and do the most stunts in the air.

5. Downhill

As the name implies, downhill biking means getting down the hill as fast as possible, much like downhill skiing. It's a time trial event - bikers don't ride together but rather start down the course at intervals. This is because the way down is not smooth - there are plenty of obstacles to negotiate along the way.

6. Freeride

Freeriding is a sport that has just recently come into vogue. The courses feature man-made obstacles such as teeter totters and skinny bridges, and can take place in-doors as well as out on specially prepared mountain courses.

7. Single speed

Those who like the uncluttered life will use a bike with only one gear and fewer components. The idea is simplicity. The racers however still go all out - both up and down courses. This sport is popular around the world.

8. Urban

Most cities were not designed for the bicyclist - and people on two wheels are resented by those on four. And then there are the pedestrians... However, people who don't live near mountains or hills haven't let that stop t hem from creating challenging, man-made courses - with all the obstacles available in urban areas.
