What is this thing you call Mtn Bike?A mountain bike or mountain bicycle (abbreviated MTB or ATB (all terrain bicycle)) is a bicycle created and made for off-road cycling, including jumps, and traversing of rocks and washouts, and steep declines, on dirt trails, logging roads, and other unpaved environments:mdash;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 tyre sizes to be meaningful. Wheels used on mountain bikes usually use wide, knobby tires for good traction on uneven terrain and shock absorption. In the current century 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.
