They often feature a variety of components, such as pegs that allow for trick variations and a wider stance for better balance. 3. Flatland BMX Bikes Flatland BMX bikes are specialized for performing tricks on flat ground without the requirement of ramps or obstacles. These bikes usually have a shorter wheelbase, allowing for a greater range of motion and easier maneuverability.
