GT grew out of the frames Gary Turner started welding in California in the early 1970s, and became one of the defining names of BMX and mountain biking. Its signature Triple Triangle frame design, with the seatstays extended to the top tube, is instantly recognisable.

Today GT's mountain range runs from the Force and Sensor trail bikes to the Fury downhill race bike and the Zaskar, alongside the BMX heritage that made its name. It is now part of the Pon Holdings bike group.
