The Giant ATX 2 is Giant's sound entry-level mountain bike and comes in 6 sizes from XXS for young trail dudes from around 10 years old to XL for 6' 4" adults.

To illustrate what lengths Giant go to ensure a properly proportioned, balanced bike, the XXS, and extra small ATX comes with 26" wheels. The larger sizes (S-XL) come with the new standard 27.5" wheels.
