From parkways to paths and everything in between, this versatile bike can add some spice to your commute or fitness routine. With its flat handlebar, upright positioning and suspension fork, it’s cool and capable on-road or off-road.
With a rugged personality and a smooth riding style, ATX features the familiar flat-handlebar look of a traditional mountain bike. It has a lightweight yet durable ALUXX aluminum frame and a suspension fork with 100mm of smooth travel to soak up bumps. The wheel diameter varies based on bike size, with 26-inch wheels on smaller frames and 27.5 on larger ones. This tailors the bike’s handling to a rider’s height. Powerful brakes deliver confident handling in all types of weather, and integrated mounts make it easy to add racks or fenders to suit your riding adventures.
With a mountain bike style flat handlebar, and suspension fork, you can ride road or dirt with confidence.
