Product Information

Full details

The Hope E-Bike Speed Sensor (R32) is designed for e-bike owners looking to replace or upgrade their speed sensing components on 6-bolt rotor systems. It offers a reliable, low-profile solution for tracking bike velocity, provided your specific motor system utilizes a magnet positioned 32mm from the axle center point. Users should be aware that due to the high variation in e-bike magnet technology, this sensor is not a universal fit and is explicitly incompatible with the Specialized Turbo Levo SL 1.2 SL motor.

FAQs

Does this work with Centerlock rotors?

No, this sensor is specifically designed for 6-bolt rotor systems.

Can I use this on my Specialized Turbo Levo SL?

No, this unit is explicitly not compatible with the Specialized Turbo Levo SL featuring the 1.2 SL motor.

What happens if my magnet is not at 32mm?

The sensor will likely fail to trigger, meaning your e-bike controller will not receive speed data.

Is the installation clearance critical?

Yes, you must maintain a 4.5mm gap for the sensor to effectively detect the magnetic field.

Are the mounting bolts included?

Yes, the kit includes two bolts necessary for mounting the sensor.

Troubleshooting

Motor assistance cuts out intermittently

Check the 4.5mm clearance; if the magnet has moved or the sensor is loose, the signal will drop.

Speedometer displays zero or error code

Verify that your magnet is positioned exactly 32mm from the axle center point. If it is not, the sensor cannot read the magnet pass.

Sensor bolt keeps vibrating loose

Apply a small amount of blue thread-locking compound to the threads before securing the bolts.

Pros and Cons

Pros

Durable construction typical of Hope components
Compatible with both standard and floating 6-bolt rotors
Slim 3.5mm design prevents interference with other components
Includes mounting hardware for quick setup

Cons

Not a universal fit due to varying e-bike magnet standards
Requires precise 32mm magnet placement for accurate readings
Incompatible with Specialized Turbo Levo SL (1.2 SL motor)
Requires specific 4.5mm clearance that may not fit all hub designs

Setup, Compatibility & Care

To install the R32 sensor, begin by cleaning the mounting surface on your frame or dropout to ensure a flush fit. Align the sensor with your 6-bolt rotor and secure it using the provided bolts. You must maintain a clearance of 4.5mm between the sensor face and the magnet; use a feeler gauge if necessary to confirm this distance.

Compatibility Notice: This sensor is designed for specific R32 geometry. Always verify your motor manufacturer's requirements regarding magnet field strength, as the Hope sensor may not be compatible with all magnet types. Regularly inspect the sensor housing for debris or impacts, and ensure the mounting bolts remain tight during routine maintenance. Do not attempt to use this sensor on the Specialized Turbo Levo SL equipped with the 1.2 SL motor, as it is electrically and physically incompatible.
