If your display is on but you are not getting any pedal assist, you may need to adjust your sensor.
First, ensure the battery is fully charged, the system is turned on, and the brakes are not engaged when you try to use the pedal assist.
If the pedal assist isn't engaging, check that the magnet, which is located on the spoke, is pushed close enough to the pedal sensor, which is located on the bottom bracket. You can loosen it and slide the magnet closer then tighten it as needed.
If the problem persists after checking all the above items, contact us for additional troubleshooting, or reach out to your local Schwinn dealer or bike shop.
