- The e-Bike speed motor controller is housed in an aluminium alloy shell that enhances waterproofing and durability. - Its efficient heat dissipation helps protect the internal circuitry and prevent thermal overload. - The controller provides undervoltage protection, overcurrent protection, stall protection, and other protective features to ensure safe and reliable e-bike operation. - It features multiple color coded wires with different functions; only the required connections are used, while unnecessary functions are omitted without affecting usability, making installation straightforward. - Compatibility and applications: suitable for standard e-bike speed motor setups and modular wiring configurations. Use scenarios: - Upgrading an existing e-bike for improved reliability in wet or challenging conditions. - Building a custom e-bike with a tidy, simplified wiring harness by attaching only the needed functions. - Replacing a failing controller in a commuter or light-duty e-bike that requires robust protection features.
