Bmx flatland is a sport or artistic expression that has evolved from its beginnings in the mechanical aspects and style still in many cases the mechanical aspects determining factors for the development of styles that have predominado at certain times. Some mechanical conditions that have facilitated new styles use and non-use of brakes in its entirety a trick that has been learned by using brakes as a result has a style and to execute this same trick without brakes will result in another totally new style. This is due in part to that vacuum that perhaps leave the brakes must be filled by adding a little more than speed in the execution of the trick or replace the brake exerting pressure with shoes on the wheel involved in the manoeuvre. Flatland with brakes: the brakes allow you to perform a series of tricks based on small jumps on wheels that were known in street slang as tintines. Many of the stunts could run with suspended bicycle. The bicycle must be equipped with a mechanism that prevents that the guayas brakes will tangle to turn more than once in the same direction the handlebar. Flatland without brakes: the execution of tricks without braking gives as a result very fast movements and combinations between tricks that in many cases are almost as impossible to perceive with the naked eye, are also produced incessant spins on a same axis maintained by inertia and slight body movements. The bicycle in this case has less weight by not having an a pair of handles, spurs, wires and rotor. Flatland with only front brakes: the practice of tricks of the flatland with only front brakes is an intermediate option between the two and is currently the greater host has had among the pilots of the flatland bmx. The style that emerges here is either the same one that arises from the Flatland with brakes and the Flatland without brakes depending on whether the pilot performs his tricks preferentially on the front wheel or rear wheel.
