Trek FX 1 Stepover Gen 4 - Era White

The FX 1 is a versatile, sleek hybrid bike engineered for everyday recreation, fitness tracking, and local city commuting. Built around the same lightweight Alpha Gold Aluminium frame design shared across the premium FX range, it utilizes an incredibly strong steel fork and an easy-to-use 2x8 speed Shimano drivetrain to deliver an ultra-wide range of gears for tackling hills. Paired with mechanical disc brakes for crisp, predictable stopping power in both wet and dry weather, the FX 1 comes completely ready to be configured with commuter racks, mudguards, and fitness accessories to conquer whatever your daily route looks like.
