Mountain Bike

Mountain Bike:
 
A mountain bike or mountain bicycle (abbreviated MTB or ATB (all-terrain bicycle)) is a bicycle created for off-road cycling. This activity includes traversing of rocks and washouts, and steep declines, on dirt trails, logging roads, and other unpaved environments—activities usually called mountain biking. These bicycles need to be able to withstand the stresses of off-road use with obstacles such as logs and rocks. Most mountain bikes use wheels with rims which are 559mm in ISO sizing, colloquially referred to as "26-inch", although the term is inaccurate as it covers too many rim and tire sizes to be meaningful. Wheels used on mountain bikes usually use wide, knobby tires for good traction on uneven terrain and shock absorption. Since 2000, front wheel suspension has become the norm and full front and rear suspension has become increasingly common. Some mountain bikes are also fitted with bar ends on the handlebars to give extra leverage for hill-climbing.

Pros: With generally heavier frames, wider tires with knobbly bits on them, and typically more comfortable to cycle, mountain bikes are more durable over rough terrain and have seating positions that allow you to sit more upright, with the flat handlebars… which is probably the better option for people who suffer with back problems. These can be considerably less expensive than road bikes.
Cons: Their durability and stability in rougher terrain result in a sacrifice of speed elsewhere. The many “extras” one can get on mountain bikes are usually arbitrary features for the average cyclist. Unless your mind is set on particular off-road road routes, where you’re gonna be bouncing all over, an expensive “pimped out” mountain bike may not be for you.
