Flatland Bikes
Although the flatland bicycle is similar to most other BMX bicycles, flatland is often performed with specially designed frames with geometry (head tube angle, top tube length, etc.) suited to the needs of flatlanders. Front and rear bolt-on pegs, a hollow compression bolt on the forks for the front brake cable, and a rear brake cable detangler or Gyro to allow the bars to rotate endlessly without tangling the brake cables. Also invented specifically for flatland riding is the rear hub mechanism known as a freecoaster, which allows the rear wheel to roll backwards without engaging the hub and making the cranks rotate backwards as they would on a normal freewheel or cassette style hub. Other technical bicycle setup specifics can include zero offset forks, narrow handlebars, very high pressure tires (100psi and higher), and a very small front sprocket (18-28 teeth).
