  • FX 3 Disc is a versatile hybrid bike that's primed for performance, comfort and utility. It has features like a lightweight aluminium frame, a carbon fork, a 1x drivetrain and powerful disc brakes that stop in any weather. It's a commuting pro if you want it to be, or the perfect fitness companion on road and rail trails.


    1. The 1x drivetrain gives you all the gears you need and none you don’t
    2. It's easy to accessorise with an MIK rear rack, a kickstand, mudguards, lights and more!
    3. 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
    4. The cables are routed internally, which protects them from the elements and adds to the bike's sleek look
    5. You can pair FX with your smartphone and send your ride data to your favourite fitness app when you add DuoTrap S
