It's right for you if...
You're a commuter or fitness rider who’s having fun spending more time in the saddle. You want a great-looking bike that's versatile, comfortable and built with quality parts that will perform on longer rides.
The tech you get
A lightweight aluminium frame, a carbon fork, hydraulic disc brakes for all-weather stopping power and a simple 1x drivetrain that ditches the front derailleur for less clutter and easier operation. Don't worry, with the wide-range 11-46 cassette still gives you all the gears you need to conquer hills and crush flats. Plus, a vibration-absorbing handlebar and ergonomic grips for more comfort on every ride.
The final word
FX 3 Disc is a lightweight and fast fitness bike, commuter and neighbourhood cruiser all in one. For all the great things about this bike, the best tech upgrade is the simple-yet-capable 1x10 drivetrain.

- The 1x drivetrain gives you all the gears you need and none you don’t
- It's easy to accessorise with an MIK rear rack, a kickstand, mudguards, lights and more!
- It's versatile and does whatever you want it to do, whether that's riding for fitness, commuting or cruising to the farmer's market to do the weekly shop

- You can pair FX with your smartphone and send your ride data to your favourite fitness app when you add DuoTrap S
1x drive train
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.
Make it your own
Customise your bike with fenders, racks, bottle cages and more to make it your own.
Rack & mudguard ready
Built-in mounts make it easy to add racks and mudguards for added versatility.
IsoZone handlebar and grips
Suspension for your hands. Our exclusive vibration-damping IsoZone material absorbs road bumps and buzz, giving you more control and an incredibly comfortable ride.
Internal cable routing
We route shift and brake cables through the frame to keep things clean and simple. And it looks great, too.
Hydraulic disc brakes
Hydraulic disc brakes offer the absolute strongest stopping power even in wet and muddy conditions.
Lightweight fork with carbon fibre legs soaks up hand-numbing road vibration.
DuoTrap S compatible
DuoTrap S (sold separately) integrates a Bluetooth®/ANT+ sensor into the frame. Log routes and track fitness progress on your computer or smart phone with no external sensor. Works with all major ANT+ wireless players, including Bontrager, Garmin, PowerTap, and SRM.
