Colour: GALACTIC GREY

The FX 3 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.

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.

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 11-48 cassette still gives you all the gears you need to conquer hills and crush flats. Plus, you get vibration-absorbing handlebars with ergonomic grips for more comfort on every ride.

The FX 3 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
- The cables are routed internally, which protects them from the elements and adds to the bike's sleek look

Shimano CUES
Inspired by rider demand for trouble-free drivetrain longevity and performance, Shimano CUES offers a new foundation for versatility and durability across a range of both electric and standard bikes. CUES features Shimano's new LINKGLIDE drivetrain technology for significantly increased life on wear items like chain, cassette and chainrings.

Shimano LINKGLIDE
LINKGLIDE technology has been specifically engineered for incredible durability while still delivering smooth and decisive shifting - along with a great pedalling experience. Available exclusively on Shimano CUES drivetrains.

Upgrade your pedals and love your bike more
Pedals are two of the five touchpoints that connect you with your bike, and even though this bike comes with a pair, upgrading to pedals that boost control and grip will greatly improve your ride. See the pedal guide and find the best pedals for your riding style. We recommend flat pedals for simple versatility.
