Product Information
Full details
The Hope E-Bike Speed Sensor (R32) is designed for e-bike enthusiasts looking for a reliable, bolt-on solution to track wheel rotation speed on bikes configured with a magnet 32mm from the axle center. Ideal for users operating 6-bolt rotor systems, it offers a robust build and straightforward installation; however, potential buyers must verify their specific motor magnet placement, as compatibility is not universal across all e-bike brands.

Installation requires removing the existing 6-bolt rotor, positioning the sensor unit, and securing it using the provided bolts. Ensure the gap between the sensor and the magnet is exactly 4.5mm.
Compatibility Warning: Before purchase, measure the distance from your axle center to your current magnet position. If it is not 32mm, this sensor will not register speed correctly. It is confirmed to be incompatible with the Specialized Turbo Levo SL with the 1.2 SL motor. For care, periodically check the mounting bolts for tightness and ensure no debris or mud is obstructing the gap between the sensor face and the magnet.
