A BMX bike is a type of bicycle designed for performing tricks, racing, and riding on rough terrains. It typically features a lightweight frame, smaller wheels, and a single gear, making it agile and easy to maneuver. The design allows riders to perform stunts like jumps and flips, which are popular in BMX competitions. BMX bikes come in various styles, including freestyle and race models. Freestyle bikes are built for tricks and park riding, while race bikes are optimized for speed on dirt tracks. Both types emphasize durability and strength to withstand the demands of extreme riding.
