Follow your own route, wherever it may lead. Roam is built for all types of terrain, so your choices are unlimited. Smooth roads, rough roads, dirt paths or trails, now you can ride it all with comfort and style.

With its confident, flat handlebar positioning and lightweight ALUXX aluminum frame, Roam gives you all the best qualities of a mountain bike and a road bike. Its front suspension and new D-Fuse seatpost absorb road shocks and vibrations, adding comfort and control. It has powerful disc brakes and durable components, so it can take some bumps on rough city roads. And the fast rolling 700c wheels with Giant’s EasyRide Tubeless tires can handle smooth roads or dirt with less risk of a flat tire, making it a great choice for town-to-trail adventures.

Key Performance Factors

Agility and control

Updated flat-bar frame geometry puts the rider in a position that balances efficiency with stability, and disc brakes give you added control on rugged roads or dirt.

Smooth-riding comfort

D-Fuse seatpost and suspension fork absorb road shocks and vibrations, and EasyRide Tubeless tires let you run lower pressure for a smoother ride quality and a reduced risk of flats.

Integrated rack mounts

Compatible with rear racks, allowing easy cargo capacity for daily trips or longer treks.

  • Weight
    The most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.
