FX 3 Disc is a versatile hybrid bike that's primed for performance, comfort, and utility. It's a commuting pro if you want it to be, or the perfect fitness companion on pavement and rail trails.

It features a lightweight Alpha Gold Aluminum frame plus a carbon fork that helps to smooth out vibrations from the road. A vibration-absorbing handlebar and ergonomic grips give you even more comfort on every ride. Shimano hydraulic disc brakes give you powerful stopping power in all-weather.

For all the great things about this bike, the best tech upgrade is the simple yet-capable 1x10 drivetrain. An easy to use 1x drivetrain that ditches the front derailleur for less clutter and easier operation. Don't worry, the wide-range 11-46 cassette still gives you all the gears you need to conquer hills and crush flats.

For the commuters, students and shopping at the market, there are mounts for a rear rack to carry pannier bags

Fitness enthusiasts will love adding Bontrager's DuoTrap to their frame (sold separately) that tracks fitness progress to their bike computer or phone to share on fitness apps such as Strava.

Step up to the FX 4 Sport if you are looking for a lighter high-performance fitness bike with the comfort of a flatbar. This 1X OCLV carbon fibre fitness bike is perfect for everything from solo workouts to speedy group rides.

Due to supply-chain issues, Specs are subject to change without notice.

A 1x10 drivetrain means more versatility, simpler shifting and fewer things to go wrong. You still have a wide range of gears, but with lighter and more intuitive shifting. Everything you need and nothing more.

Built-in mounts make it easy to add racks, fenders and kickstands for versatility.

FX 3 includes Bontrager Satellite Plus IsoZone handlbar and grips to reduce vibrations for a more comfortable ride.

You can pair FX with your smartphone and send your ride data to your favorite fitness app (ie. Strava) when you add DuoTrap S.
