Foutcodewijzer: a diagnostic path for e-bike workshops
A Dutch troubleshooting tool for bicycle mechanics that turns an e-bike fault code—or a plain-language symptom—into a step-by-step inspection.
Field notes
The workflow accepts either a displayed code or an ordinary symptom description, then narrows the fault through sequential yes-or-no checks. Instructions specify both the inspection location and the physical action, such as placing the bicycle on its stand and slowly turning the rear wheel to inspect the magnet and sensor. The homepage states that the system contains 499 codes across 18 drive systems and is intended for unlimited mechanics at one workshop; it also describes a future €39.95 monthly price.
