Trek FX+ 1

FX+ 1 is a versatile and fast throttle e-bike built for cruising through town with an ear-to-ear grin. Its handlebar throttle makes getting up to speed a breeze, and pedal assist gives you a smooth boost while you ride. Plus, an EasyMag magnetic charger with a sleek, portable wall-mounted system makes charging between rides easier than ever.

• Wide, stable tires deliver tons of traction and confidence for riding through town, on paths, and on rail trails
• Integrated lights, turn signals, and brake light help you see and be seen wherever you roll
• You get low-maintenance, reliable shifting thanks to Shimano's 8-speed ESSA drivetrain

A better way to produce aluminum

Starting in 2024, we began removing high-emission aluminum from our manufacturing and replacing it with low-emission aluminum made with renewable energy. By October 2025, nearly every alloy bike we make - this one included - had made the switch, driving a major drop in our footprint.

Compliant with leading safety regulations

The e-systems on Trek and Electra e-bikes are third-party tested to meet the latest e-bike safety regulations, including the stringent UL 2849 certification — so all you have to worry about is where your e-bike will take you next.
