TypeMountain Bike


Giant ATX has a tough demeanor and a smooth riding style, and it has the typical mountain bike flat handlebar appearance. It sports a suspension fork with 100 mm of smooth travel to smooth out bumps and a frame made of lightweight yet strong ALUXX aluminum. Depending on the size of the frame, smaller bikes have 26-inch wheels and larger bikes have 27.5-inch wheels. This adjusts the bike’s handling to the height of the rider. Integrated attachments make it simple to install racks or fenders to fit your riding experiences, and powerful brakes give assured handling in all weather conditions.

ALUXX-Grade Aluminum

The Giant ATX frame is constructed from the brand-exclusive ALUXX alloy. The tubes of the frame are thicker in certain places than others, balancing weight and strength to provide a stable platform that is yet simple to handle. If you use your ATX for commuting or city riding, you can stow your necessities in the frame’s rack mounts.

Long-lasting dependability is provided by the sturdy ALUXX aluminum frame material, which is guaranteed by a lifetime frame warranty.


The 26″ variant of the Giant ATX is designed for smaller riders, while the 27.5″ (650b) models are appropriate for all other rider heights. All Giant ATX models come equipped with disc brakes for powerful all-weather braking, a high-quality Shimano drivetrain, and an SR Suntour suspension fork to smooth out bumps and increase control when riding off-road. The Giant ATX is the perfect bike for comfortable, adaptable riding on forest routes, easy trails, and even your daily commute.

Internal Cable Routing

Giant ATX offers features like internal cable routing that make it stand out from the competitors. This extends the life of the cables and improves the efficiency of the braking and shifting by keeping the cables snugly tucked inside the frame and free from grit and grime that can cause premature wear.
