What would an "Overlander" ride?

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.

Carry More

The GMX+ lets you carry more water or load more gear. The titanium frame includes mounting points on all rear stays and offset on the downtube, allowing riders to run a full-size frame bag plus 1 litre bottles to either side. The Seek 430 fork has 6 x M5 mounting points on each side, with a recommended load capacity of 3 kilograms across three mount points.

Walmer Bars

Our ultra-wide drop bar, the Walmer Bar, is the perfect companion to the GMX+ with rugged off-road riding. This flared drop bar is available in 4 sizes - 46BP, 50BP, 55, 60 cm (hood measurement, +15 cm for the drop) and will provide the rider with more stability, hand positions, and storage space than other available handlebars.

Bigger Tyres

The Seek 430 fork allows clearance for up to 29 x 3.0" plus-size mountain bike tyres (27.5 x 3.0" in sizes XXS–XS). A bigger tyre means more traction and less rolling resistance, letting you ride efficiently across more tricky terrain such as sand, rocks, and snow.

Frame Sizing

The GMX+ ranges from size XXS to XXL, including an 'extra medium' option. Size SM–XXL is designed around 29" wheels, while XXS and XS frames run 27.5" wheels, ensuring geometry proportions and handling characteristics are consistent across all sizes.

Drop Bar or Flat Bar

The GMX+ can accommodate a drop bar or flat bar. Use either a drop bar, such as our WALMER Bar, together with a short stem. Or our flat bar, the REMLAW, replicates the same reach position as a drop bar, therefore there is no need for a longer stem like many other flat bar options.
