FX+ 2 Midstep is a fitness-focused electric bike with a confidence-boosting midstep frame that’s easy to get on and off. It delivers pedal assist up to 28mph and features an optional throttle for extra support when you want it. A suspension fork and seatpost help smooth rough paths, while gravel tires, built-in lights, turn signals, and the Trek Central app keep your ride comfortable, visible, and connected. This class 3 e-bike is prohibited from sale in California under CA SB 1271 and cannot be shipped to California.

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.

See and be seen

A rear brake light with integrated turn signals helps alert others of your next move, while the fork-mounted headlight turns with you to light the way around every corner.

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+ 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. 

Carry what you need

The MIK rear rack supports up to 55 lbs, so you can easily carry your daily essentials — from work bags and groceries to everything you need to break a sweat.
