Battery questions
How long does it take to charge the battery?

Is the battery removable?
The battery should only be removed by an authorized Trek dealer. Do not try and remove the battery at home.
Can you upgrade to a bigger battery?
No, the FX+ 1 frame was designed to fit the included 540Wh battery. Larger capacity batteries typically have larger dimensions that will not fit in the frame. Additionally, the system is programed to only work with the 540Wh battery we’ve selected. Do not swap or use non-approved batteries on your Trek e-bike to maintain safety and compliance.
What if I want more range?
Range for FX+1 will vary based on a number of factors like the weight on the bike, the terrain you're riding, and wind conditions. In addition, how often you use the throttle vs the pedal assist will also effect your range. Throttle will use up more battery as it's boosting the bike purely on motor power while pedal assist will give you more range. If you want to further maximize your range, you can adjust the individual assist levels to decrease power use in the Trek Central apps' Motor Tuning feature.
Is there a specific way to attach the EasyMag charger?
The EasyMag charger has a directionless mount so it easily (and magnetically) snaps on the charge mounts on the frame without requiring a specific orientation.
How will I know my EasyMag charger is charging?
