What is the Giant ATX?
The ATX is Giant's entry-level mountain bike.
It's designed for pavement, smooth dirt and smooth gravel trails. It's not designed for mountain biking or rough mountain bike trails.
The ATX is available in several frame sizes (from XS to XL) to suit different height riders.
Frame sizes XS and S use a 26-inch wheel.
A 27.5-inch wheel is used for frames sizes S to XL.
Note that the S frame size is available in both the 26 and 27.5-inch wheels.
Currently, there is only 1 ATX model (so there's not a lot of options).
But:
if you're open to other options that are similar (and slightly better) than the ATX, we've got some to show you below.
