Overview:
The GMX+ is inspired by the intrepid Overlanders of the 1890s, who covered incredible distances without support across the harsh Australian outback. We have designed a bike that can do the same, but with much more ease using today's modern technology. The GMX+ is an adventure bike designed with wider tyre clearance thanks to our innovative carbon fork, ultra-wide drop bars for stability, and numerous mounting points for storage or water.
Tested in real-life conditions, the original GMX was designed for Race to the Rock, a harsh, remote desert race in Australia. With testing came improvements to the bike geometry and fork clearance, and so the GMX+ was born.
In recent years, the GMX+ has taken on some of the most challenging races worldwide, including Tour Divide, Silk Road Mountain Race, and Race to the Rock.
