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 aluminum 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 final word

FX 3 is a lightweight and fast fitness bike, commuter, and neighborhood cruiser all in one. For all the great things about this bike, the best tech upgrade is the simple-yet-capable 1x10 drivetrain.
