Giant 2026 Roam 4
With its flat handlebar, comfortable upright positioning and smooth, powerful disc brakes, Roam combines the best qualities of a road bike and a mountain bike. Now you can follow your own route wherever it goes.
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
The 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.
