  • The FX Sport 6 is the lightest and fastest fitness bike in the line-up. It has every performance feature of a high-end road bike, with the added benefit of flat handlebars for additional comfort and control. A lightweight 400 Series OCLV Carbon frame, a high-quality Shimano drivetrain and Bontrager carbon wheels make it the best choice for serious fitness riders with serious goals.


    1. A fitness bike that's every bit as fast and capable as the race bikes found in our road line-up
    2. The 1x drivetrain delivers a wide range of gearing with the simplicity of a single shifter
    3. The cables are routed internally, which protects them from the elements and adds to the bike's sleek look
    4. It's easy to accessorise with mudguards, lights and more!
