FX Sport 4 is where performance fitness bikes begin. A lightweight aluminum frame, a wealth of performance features, and a 1x11 drivetrain that simplifies shifting without sacrificing gear range give you the capability to take on longer commutes and faster recreational rides without sacrificing the versatility that has made FX Trek's best-selling lineup ever.
It's right for you if...
You've got goals to demolish, and you need a bike that can help you finish a 50-mile charity ride, your first sprint triathlon, your daily commute, or any other fitness milestone. You want a performance hybrid that's comfortable on longer rides with big hills and versatile enough to carry groceries home after your workout.
The tech you get
A lightweight aluminum frame, a carbon fork that absorbs road vibration, hydraulic disc brakes for all-weather stopping power, a Shimano Deore 1x11 drivetrain with a wide range of gears for hilly routes, rack and hidden fender mounts, fast-rolling Bontrager tires, IsoZone ergonomic grips, and compatibility with DuoTrap S so you can track your fitness gains.
The final word
If you have fitness goals, FX Sport 4 will help you cruise past them. It's the perfect combination of road bike speed and hybrid bike versatility: comfortable over the long haul, quick when you want to put the hammer down, and reliable in all weather conditions and a variety of road surfaces.
