FAQs
What is the range of the Powerfly FS+ 4?
The range varies significantly based on terrain, rider weight, assist level, and battery condition. The standard 600 Wh battery can provide assistance for many hours, with options to upgrade to an 800 Wh battery or add a range extender for longer rides.
How do I adjust the geometry of the bike?
The bike features Mino Link, which allows for adjustment of the geometry. By rotating the small chip located on the rocker arm, you can adjust the head angle and bottom bracket height to fine-tune handling characteristics.
Can I ride this bike in the rain?
Yes, the bike is designed to be ridden in various weather conditions. However, it's recommended to clean and dry the bike thoroughly after riding in wet conditions to prevent component damage and corrosion.
How often should I update the Bosch system firmware?
It's recommended to check for and install firmware updates periodically through the Bosch eBike Flow app. Updates can improve performance, fix bugs, and enhance features.
What is the maximum torque the motor can provide?
The Bosch Performance Line CX motor provides 85 Nm of torque by default. Through the eBike Flow app, this can be increased up to 100 Nm.
What is the difference between the standard battery and the optional 800 Wh upgrade?
The 800 Wh battery offers a larger capacity, providing approximately 33% more range compared to the standard 600 Wh battery, allowing for longer rides or more assistance on challenging terrain.
Is the bike compatible with a child seat?
The frame has mounts for racks, which may support some child seat systems. However, compatibility and safety should be verified with the child seat manufacturer and by consulting a bike shop. The bike's intended use is typically for single riders.
Troubleshooting
Motor does not engage
Ensure the battery is charged and properly seated. Check that the Purion 200 remote is active and that the bike's speed sensor is clean and properly aligned.

Note the error code displayed and consult the Bosch eBike systems manual or contact a Trek dealer for interpretation and resolution. Common codes can often be cleared by restarting the system.
