FX+ 1 is a lightweight, versatile fitness e-bike built to make everyday rides faster and more fun. Pedal assist up to 20mph gives you a smooth, natural boost, and the thumb throttle makes getting up to speed feel effortless. Gravel tires add stability across surfaces, while integrated turn signals and a brake light help you stand out and ride with confidence.

• You get the convenience of a throttle for accelerating and the smooth support of pedal assist while you ride
• The portable magnetic wall-mount charger makes getting your battery ready to ride a hassle-free process
• 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

Throttle up the fun

Press the thumb throttle and go — whether you’re starting from a stop or climbing a hill, you’ll get a boost right when you need it. Plus, the throttle works with your assist level, so the extra support feels smooth, natural, and fun.

Send the right signals

FX+ throttle includes a rear brake light with built-in turn signals, so you’re easier to see and can signal your moves with confidence.

Charging made simple

The EasyMag charger uses a directionless magnetic connection to easily snap into place every time. LED lights clearly show your battery level at a glance, and the optional wall mount keeps your setup clean and ready to grab and go.

Stay connected with Trek Central

FX+ throttle pairs with the Trek Central app so you can easily adjust your bike's settings for longer range, map routes, track ride stats, optimize your bike battery, and more!

eLock bike security

Lock or unlock your e-bike directly from the Trek Central app or on the full-color display for added security. Enable automatic unlocking when your phone is within Bluetooth range for seamless, keyless convenience. 

Go beyond the pavement

Wide gravel tires add stability and grip across mixed surfaces, smoothing out rough pavement and soaking up bumps. They give you the confidence to explore beyond the pavement — from city streets to dirt paths and gravel roads.
