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, a wide-range 18-speed Shimano drivetrain that's great for conquering hills, a vibration-absorbing handlebar and ergonomic grips, extra mounts for accessories like a rack and fenders, and puncture-resistant tires.
The final word
FX 3 Disc 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 2x9 drivetrain. This 18-speed setup is like what you'd see on a road bike: light, efficient, and built for speed.

Sizing & fit
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local retailer.
