Giant ATX Bike XL
The Giant ATX is the honest, ready-to-ride hardtail that gets you on the trail without draining your wallet.
This is an entry-level mountain hardtail for new riders, students, and anyone who wants one bike for dirt paths and pavement alike. Rugged, simple, and easy to live with, the ATX handles Valley bike paths on weekdays and mellow foothill singletrack on the weekend. It's the smart first mountain bike.
It's right for you if:
You're new to riding and want a capable bike that won't break the bank.
You need one do-it-all bike for trails, campus, and commutes.
You want an XL frame with room to stretch out.
You value a trusted local shop over a big-box build.
Why you'll love it:
A suspension fork smooths out ruts and roots so rough ground feels manageable.
Disc brakes give you reliable stopping in dust or drizzle.
The lightweight ALUXX aluminum frame makes climbs and quick stops easier.
Wide-range gearing helps you spin up hills without grinding.
The tech you get: a lightweight ALUXX aluminum frame in XL, a suspension fork, 27.5-inch wheels, disc brakes, and a wide-range drivetrain.
