Product information

Closely related to Giant off-road bikes, ATX features the familiar flat-handlebar and 100mm suspension fork of a traditional XC mountain bike. A lightweight ALUXX aluminium frame, engineered with comfortable geometry for challenging terrain, adds to its rugged personality. It also uses size-specific wheel diameters—smaller size bikes use 26-inch wheels, while larger sizes use 27.5. This tailors the bike’s handling to every rider’s size and height. Powerful disc brake technology gives you confident handling in all weather or riding conditions, and integrated mounts let you easily add racks or fenders to suit your riding adventures.



With a mountain bike style flat handlebar, suspension fork and disc brakes, you can ride road or trail with confidence.


Frameset constructed with high-quality ALUXX aluminium.


Frame geometry puts the rider in a position that balances efficiency with stability on rough roads, paths or trails.
