Product Information
Full details
The Hope E-Bike Speed Sensor R32 is designed for e-bike owners utilizing Hope Technology rotors who need a reliable, precision-engineered magnet system for their speed sensing needs. It provides a robust and aesthetically pleasing solution for 6-bolt mounting, though owners should verify their motor's specific spacing requirements before purchase as it is not a universal fit for all e-bike systems.

FAQs
Will this work on a Centerlock rotor?
No, this sensor is specifically designed for 6-bolt rotor interfaces.
Is this compatible with my Specialized Turbo Levo SL?
No, this product is not compatible with the Specialized Turbo Levo SL featuring the 1.2 SL motor.
Do I need special tools to install this?
You only need the standard Torx or hex tool used to remove your existing rotor bolts.
Can I use this with non-Hope rotors?
While it is designed for Hope rotors, it may work with other 6-bolt rotors provided the bolt pattern and spacing requirements match.
What is the primary function of the R32 designation?
The R32 designation indicates the magnet is positioned at a 32mm distance from the axle center, which is the required spacing for your specific e-bike motor sensor.
Troubleshooting
Speed sensor not registering movement
Check that the sensor is positioned exactly 32mm from the axle center and that the 4.5mm clearance gap is maintained.
Sensor hitting the frame or mount
Verify that the wheel is seated correctly in the dropouts and that no bent hardware is causing misalignment.
Loose sensor after trail ride
Ensure mounting bolts were installed with proper thread locker and torqued according to Hope rotor specifications.
Pros and Cons
Pros
- High-quality anodized finish for durability
- Perfect integration with Hope Technology rotors
- Lightweight and low-profile design
- Includes necessary mounting hardware
Cons
- Not compatible with Specialized Turbo Levo SL 1.2 SL motor
- Requires specific 32mm positioning which may not fit all hub architectures
- Limited to 6-bolt rotor interfaces
Setup, Compatibility & Care
Installation requires removing one of your 6-bolt rotor mounting bolts and replacing it with the provided hardware to secure the sensor. Ensure that your e-bike frame or motor system explicitly requires a 32mm radius for the speed sensor magnet, as variance in this measurement will result in signal errors. You must verify a 4.5mm gap between the sensor and the frame-mounted receiver to prevent contact and potential damage during wheel rotation. To care for the sensor, periodically check that the mounting bolts remain torqued to manufacturer specifications and wipe the magnet clean if debris or brake dust accumulates, as foreign objects can sometimes interfere with magnetic induction.
