Dirt Bikes
Dirt bikes are different from mountain bikes, although at first glance they may seem similar. Both feature bulky frames, both have smaller wheels than road bikes, and both sport wide treads. But a dirt bike serves a different purpose than a mountain bike, and the particulars of its construction are where it becomes better suited to its rider’s needs.
Dirt bikes were the first stunt bikes used. People would make large earth ramps, and jump the bikes off them to do tricks. A traditional bike frame cannot withstand the pounding such treatment gives, and so the need for change arose. Dirt bikes normally only sport a single gear, and if they have any suspension at all, it is a low travel front suspension.
The reason for this is that dirt bikes are often used to perform both front and rear wheelies. A wheelie is when a rider balances the bike on a single wheel, either in a single position, or while in motion. The balance required for such a feat is delicate, and the additional give of a suspension amplifies the fine corrections necessary to maintain a wheelie. Dirt bikes also often sport pegs on the front and rear wheels. These pegs allow a rider to shift the focus of weight off the pedals while performing certain tricks.
