Product Details
Brand: TREK

FX 3 is a versatile hybrid bike that's primed for performance, comfort, and utility. It has features like a lightweight aluminum 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 pavement and rail trails.

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 11-46 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.

Why you'll love it

  1. The 1x drivetrain gives you all the gears you need and none you don’t
  2. It's easy to accessorize with a MIK rear rack, a kickstand, fenders, lights, and more!
  3. 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 pick up groceries
  4. The cables are routed internally, which protects them from the elements and adds to the bike's sleek look
