In some cases riders of the Quick 4, Quick 5 and Treadwell 3 have noticed the speed and distance being recorded by the Cannondale Wheel Sensor and Cannondale App are much higher than reality.
We are investigating potential causes of interference that result in inconsistent speed recordings, but in the meantime we have found it may help to move the Wheel Sensor to the opposite side of the front wheel. Electromagnetic interference can cause issues with the Wheel Sensor. In many cases moving the sensor to the opposite side of the wheel (to the drive-side) resolves the speed recording inconsistencies. Also please ensure the sensor is as far away as possible from any magnets, dynamos, or similar accessories that may be mounted to the bike.
If you do not feel comfortable performing this service on your bicycle, please take your bike to the nearest authorized Cannondale dealer.
For full details and helpful diagrams, please refer to the sensor installation instructions that came with your bike while mounting the sensor to the right side of the wheel, opposite of the disc brake. Those instructions may also be downloaded here.

Simplified instructions:
- Take some close-up pictures from both sides showing how your wheel sensor is attached to the spokes now. You'll mimic that on the other side.
- Get a 2mm Allen wrench
- Loosen the mounting bolt of the wheel sensor enough to remove the wheel sensor from the spokes (you don't have to unscrew it very far)
- Reposition the sensor on the inside of the spokes on the right side of your front wheel (opposite of the disc brake)
- Take care to match how it was mounted and aligned with the spokes before – see also the diagrams in the installation instructions mentioned above
- Tighten the mounting screw until snug (take care not to over-tighten)
