If any cycle was made for doing stunts on, then it has to be the BMX bike. Before the advent of BMX bikes, kids used to modify the tires and frames of their cycles for strength, performance and personal preferences. BMX bikes were first introduced in the late 60s. However, had it not been for Bob Haro, BMX bikes wouldn't have been what they are today. Bob Haro started the Haro group of bicycles. BMX bikes are used for racing and freestyling. BMX racing takes place on sandy and hilly tracks. Freestyling refers to stunts performed on the streets, wooden platforms or uneven surfaces. It was Bob Haro who combined skateboarding stunts along with BMX freestyling, thus, taking it to the extreme level that it is today. BMX bikes differ from normal bicycles in frame construction and tire size. BMX freestyling bikes were differentiated from BMX racing bikes at a later stage. BMX racing bikes incorporate features like a straight-tube gusseted frame, reinforced handlebars, and long crank arms. The Freestyler looks almost similar to a racing bike except that it has extra space for placing the feet on while performing stunts. Most of these bikes also have a 'Gyro' located in the head tube, which allows the handlebar to be rotated 360 degrees without entangling the brake cables. Very few women riders are into freestyling. However, the number seems to be increasing nowadays. Unlike normal bikes, BMX bikes don't have any separate bikes designed for ladies, while slightly older people don't prefer BMX bikes at all. On the other hand, there are BMX bikes for the young, vigor-filled generation.
