Replacement pedal-assist cadence sensor
This wired cadence sensor detects crank rotation for the pedal-assist system and fits inside the bottom-bracket area.
- Compatible with EYBAIKC E100 Pro and E300 Pro
- Integrated ring-style sensor with attached cable and connector
- Designed as a replacement for the matching original PAS sensor
Before ordering: Compare the housing, cable connector, and mounting orientation with the original sensor on your bike. Contact EYBAIKC support if you are unsure.
Disconnect the battery before installation. Installation requires crank and bottom-bracket access; use a qualified bicycle technician if you do not have the correct tools or experience.
