This motor cable is a combined motor-to-controller connection lead for electric scooters, electric bikes and small e-moto platforms. It combines three 2.5 mm² phase cores with a separate 5×0.2 mm² signal bundle. The total length is 550 mm. Power and signal conductors are split into two distinct bundles inside one cable run.
The three 2.5 mm² cores carry the U/V/W motor phases. Because of that cross-section, losses in the power circuit stay low. Meanwhile, the five 0.2 mm² cores serve the hall sensors, the temperature sensor and other controller signal lines. One tidy cable therefore replaces several separate wires.
This lead suits builders and repairers working on three-phase BLDC drives with a separate five-wire hall bundle. That includes hub motors as well as mid-drive setups. Installation is faster, and the routing through a frame or a deck stays clearer.
Benefits and Advantages
- Low losses in the power circuit – the 2.5 mm² phase cores carry higher currents more safely.
- Temperature stability – a larger phase cross-section heats up less under longer loads.
- Clean signals – the separate 5-pin 0.2 mm² bundle carries sensor data without noise.
- Two separate bundles – power and signal conductors stay untangled from one another.
- 550 mm length – enough for most installations, without leftover cable to coil up.
- Tidy routing – one combined cable takes the place of several individual wires.
- Adjustable length – the cable can be shortened, or extended by soldering or crimping.
- Broad compatibility – it fits most three-phase BLDC drives with a separate 5-wire hall bundle.
Who Is This Cable For?
The cable is intended for electric bikes, electric scooters and small e-moto platforms. It joins the motor to the controller. Therefore it works equally well for a repair or for a fresh installation.
Compatibility is not determined by vehicle brand. Instead, it is set by the electrical specification. The cable fits most three-phase BLDC (brushless) motors that use a separate five-wire hall bundle. That covers hub motors as well as mid-drive solutions.
Technicians rebuilding an old wiring loom choose this lead often. So do self-taught installers swapping a controller. It also helps when the original motor cable has been damaged by vibration or by sharp edges.

Installation Tips
- Keep the correct U/V/W phase order and hall wire pin layout. Mixing them can cause the wrong rotation direction or fault codes.
- Protect the cable from sharp edges so the insulation stays intact.
- Secure the cable with ties wherever vibration is present.
- If you crimp the connectors, use contacts matched to the AWG/mm² and a proper crimping tool.
Why Choose This Motor Cable?
The main difference is the split between power and signal bundles inside a single cable. As a result, you do not route three thick phase wires and five thin sensor wires separately. The 2.5 mm² cross-section was chosen for urban and mid-power drives.
Furthermore, the 550 mm length matches the typical distance between motor and controller. No coiled-up excess is left behind the deck or inside the frame. The routing stays clean and easy to inspect later.
This lead is not tied to a single model. You can shorten it, or extend it when a longer run is needed. Connectors come as supplied, or prepared for crimping. Consequently, the same cable serves very different installations.
Frequently Asked Questions
Does this motor cable fit electric scooters and e-bikes?
- Yes, it is made for electric scooters, electric bikes and small e-moto platforms.
- It connects the motor to the controller on those vehicles.
Which motors is the cable compatible with?
- Most three-phase BLDC (brushless) motors with a separate five-wire hall bundle.
- Both hub motors and mid-drive setups are covered.
Is the cable suitable for higher currents?
- The 2.5 mm² phase cores suit many urban and mid-power drives.
- For very high currents, choose a cable with a larger cross-section.
Can the cable length be changed?
- Yes, the 550 mm cable can be shortened.
- Extensions can be soldered or crimped on, keeping the wire standard and insulation quality.
What do the five thin wires do?
- They carry hall sensor data, the temperature sensor line and other controller signals.
- At 0.2 mm² each, they sit in their own bundle away from the phase cores.
Which connectors does it come with?
- A 3-pin side for the phases and a 5-pin side for the signals.
- They arrive as supplied, or prepared for crimping.
How do I avoid the wrong rotation direction?
- Match the U/V/W phase order exactly to your controller.
- Keep the hall wire pin positions in their original layout.
One combined lead handles both the U/V/W phases and the sensor lines between motor and controller. With 550 mm of reach, two separate bundles and the option to shorten or extend it, this cable fits repairs and new builds on three-phase BLDC scooters, e-bikes and small e-moto platforms alike.
