Higo 3 Pin Extension Cable – IP65 Signal Connector for E-Bikes & Scooters

The Higo 3 pin extension cable is a signal-level extension lead for e-bike and electric scooter peripherals. It extends the run between an existing Higo 3 pin accessory and the controller. Typical uses include the speed sensor, the throttle, the brake sensor and other Higo 3 pin devices. The cable is rated IP65, carries up to 2 A, and uses a black flexible jacket.

This lead contains no electronics inside. Therefore it does not change the connector standard, and it adds no new functions to your system. It simply moves the connection point further along the harness. Higo is a manufacturer of sealed connectors, not a bicycle brand. Consequently, the same 3 pin format appears across many Bafang, Ananda, Das-Kit, Shengyi and Tongsheng systems.

Because of that, fitment is decided by the pin layout (pinout), not by plug shape alone. Always confirm your pinout before ordering.

Key Benefits

• Higo 3 pin standard – male and female halves mate directly, with no adapter step to another connector type.
• IP65 rating – resists dust and rain splash during outdoor riding.
• Up to 2 A rated current – matched to signal duty and small loads.
• Sealed mating – the connector clicks home and stays locked under vibration.
• Flexible jacket – the cable routes easily around frame tubes.
• Durable insulation – protects the conductors at bend points.
• Plug and play fitting – no rewiring and no soldering required.
• Black finish – blends in among the other harness sections.

Who Is This Cable For?

This extension suits electric bicycles and electric scooters built around the Higo 3 pin connector ecosystem. Above all, it fits speed sensors, throttles and other signal-level sensors that need extra reach. It is commonly used on Bafang, Ananda, Das-Kit, Shengyi and Tongsheng style installations. In those builds, the peripheral lead often falls short of the controller.

Additionally, it helps after a frame respray or a longer fork swap, when the harness route grows longer. The cable is aimed at bike mechanics and owners who service their own builds. However, it is not suitable for motor phase wires, battery power or charging. Those runs need a power-series connector with a far higher current rating.

Technical Specifications

Installation

• Switch off the system and disconnect the battery first.
• Push the Higo halves together straight, without twisting, until they click.
• Check that the cable does not tension when the bars turn or the fork works.
• Power the system up and confirm the peripheral responds.

Never twist or force the connector. Twisting can bend the contacts or damage the sealing ring.

Why Choose This Higo 3 Pin Extension?

Instead of cutting and soldering wires, you get an industrial connector with a factory sealing class. As a result, the harness stays serviceable, and the sensor comes off without tools. That matters on builds you expect to strip down again.

Unlike power-series connectors, this version is optimised for signals. Therefore the cable is thinner and easier to route through the frame and cockpit area. Moreover, the IP65 level covers everyday riding in the rain.

Frequently Asked Questions

Does this extension work with every Higo 3 pin device?

• It works when the pin layout matches your controller or peripheral standard.
• A physical match alone does not guarantee function – the pinout decides.
• It is used on Bafang, Ananda, Das-Kit, Shengyi and Tongsheng type systems.

Which accessories is this cable meant for?

• Extending a speed sensor lead to the controller.
• Extending a throttle or brake sensor lead.
• Other Higo 3 pin signal peripherals on e-bikes and scooters.

Is it compatible with a Bafang mid-drive harness?

• Yes, where the Bafang peripheral uses the Higo 3 pin format.
• Compare the pin layout against your existing accessory plug.
• The connector standard stays unchanged by this cable.

Can I use it for the motor or the battery?

• No. It carries a maximum of 2 A and is built for signals.
• Motor phase, battery power and charging need power-series connectors.

How weatherproof is the connection?

• The connector is rated IP65 against dust and rain splash.
• The click-lock mating holds under road vibration.

Does it add any features to my system?

• No. There are no electronics inside the cable.
• It only extends distance between the accessory and the controller.

How do I connect it correctly?

• Disconnect the battery, then push the halves together straight.
• Do not rotate the housing while mating the connector.

In short, this Higo 3 pin extension gives you extra reach for speed sensors, throttles and brake sensors without touching the original wiring. Check your pinout, plug it in, and route the black jacket along the frame.
