The SW900 is an e-bike LCD display designed for compatible JN controller systems. It displays riding information and provides access to supported assist and controller settings.
Important: The SW900 is not a universal replacement display. Matching the voltage, plug shape or pin count alone does not guarantee compatibility.
Choose the Correct Connector
| Connector Option | Wiring System | Before Ordering |
|---|---|---|
| 5-Pin SM Connector | Standard SM-plug wiring for a compatible JN controller system | Compare the plug gender, five-pin layout, wire sequence and cable arrangement |
| 5-Pin WP Waterproof Connector | Waterproof-plug wiring for a compatible JN controller system | Compare the plug shape, alignment marks, gender and connected main cable |

Before You Order
- Confirm that your e-bike uses a compatible JN controller system.
- Do not order only because the original display also supports 24V, 36V or 48V.
- Compare the connector type, connector gender, pin count, alignment marks and wiring arrangement.
- The SM and WP waterproof versions are different wiring options and are not automatically interchangeable.
- A matching five-pin connector does not prove that the communication protocol or wire sequence is compatible.
- Turn off and disconnect the battery before plugging in or removing the display.
- The controller, wiring harness, sensors and connector adapters are not included.
- If you are unsure, send us clear photos of the controller label, original display and connector before ordering.
