In 1972 Gary Turner designed and manufactured one of the very first BMX race bikes. Gary Turner Design, now GT bicycles has, over the many years, created competitive BMX, mountain and road bikes. They have built a long legacy of racing and winning and have continued to put all their technological knowhow and expertise into the manufacture of bikes for leisure as well as competition. Their belief that cycling, in whatever form, should be fun remains as true today as it was in the beginning. Their range of BMX, Kids, city and hybrid bikes show what GT are capable of. The heritage in BMX is clear to see with bikes that perform at the highest level.
