It's right for you if...

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.

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.
