The SurRon Hall sensor with temperature sensor is the original (OEM) motor rotor position sensor module for the SurRon Light Bee X and SurRon Light Bee L1E electric motorcycles. It combines three Hall effect position sensors, an integrated temperature sensor and a factory wiring harness in one assembly. The module plugs straight into the standard SurRon motor connectors.
Inside the module, Hall effect sensors output a digital A/B/C signal. That signal tells the controller exactly where the rotor sits at any moment. As a result, the controller commutates the motor correctly through every phase of rotation. The temperature channel runs on a separate line and reports the thermal state of the motor.
This is a replacement part rather than a tuning component. It restores factory-smooth starts and stable running, even at low rpm. Owners typically fit it when the motor stutters, refuses to start, or throws a fault caused by a failed position sensor.
Key Benefits
- OEM accuracy and reliability – an original part, matched to SurRon motor controllers.
- Smooth starts – precise rotor position reading improves pull-away from zero rpm.
- Better modulation – an accurate position signal sharpens torque control.
- Integrated temperature sensor – lets the controller run overheat protection algorithms.
- Digital A/B/C signal – three Hall channels feed position data to the controller.
- Plug and play connectors – correct pin layout and cable length, so no rework is needed.
- Factory colour coding – wires are marked to the factory diagram, which keeps wiring clear.
- Single-piece module – all sensors are replaced together, so signal levels stay even.
Who Is This For?
This Hall sensor with temperature sensor fits two models. The first is the SurRon Light Bee X, the off-road version that is not road legal. The second is the SurRon Light Bee L1E, the homologated road-going version. Both models use the same OEM motor sensor module.
The system requirement is straightforward. You need an OEM SurRon motor and controller that support Hall and temperature inputs. In addition, the module works with aftermarket controllers, provided they accept 5 V Hall signals and a motor temperature line.
The part suits owners whose motor stutters, will not start, or logs a fault from a failed position sensor. Workshops carrying out motor repairs choose it for the same reason. Furthermore, many riders keep one on the shelf as a spare before a long off-road season.

Why Choose This Sensor?
The first difference is origin. This is a genuine OEM part, not a universal substitute. Pin layout and cable length match the factory item, so no adaptation is needed. Consequently, fitting involves no cutting and no soldering.
The second difference is the integrated temperature channel in a single module. Many basic Hall sensors carry only the position signal. This one additionally lets the controller watch motor temperature and cut power before overheating occurs.
The third difference is the complete set of three Hall elements. Because you replace the whole module instead of one element, signal levels stay consistent across all channels. Motor behaviour therefore remains stable over time.
Installation
Start by disconnecting the battery. Next, remove the motor cover to reach the sensor module. Then unplug the factory connectors and withdraw the old unit. Fit the new module, reconnect the plugs and refit the cover before reconnecting power.
Frequently Asked Questions
Does this Hall sensor fit the SurRon Light Bee X?
- Yes, it is the OEM sensor module for the Light Bee X off-road version.
- The Light Bee L1E road-legal version uses the same module.
Is a separate temperature sensor needed for the Light Bee L1E?
- No, the temperature sensor is built into this module.
- It reports motor thermal state on its own dedicated line.
What voltage does the module run on?
- The Hall sensors run on 5 V DC, typically.
- That supply comes from the controller output.
Will it work with an aftermarket controller?
- Yes, if the controller accepts 5 V Hall signals.
- It also needs an input for the motor temperature line.
Do I need to cut or solder any wires?
- No, the harness uses factory SurRon connectors.
- Cable length and pin layout match the original part.
Should I replace one Hall element or the whole module?
- Replace the whole module, because it is supplied as one piece.
- All three channels then share the same signal level.
What symptoms point to a failed position sensor?
- The motor stutters, will not start, or logs a fault.
- Starts from zero rpm often feel rough or hesitant.
A working rotor position signal underpins everything the controller does with the motor. This module restores that signal on the Light Bee X and Light Bee L1E, and it adds the temperature line the controller uses for overheat protection. Because it arrives with the OEM harness and factory plugs, the repair stays simple and the motor returns to its original behaviour.
