- The e-bike speed motor controller uses an aluminium alloy shell for enhanced waterproofing and durability. - It has good heat dissipation to protect the internal circuit and prevent thermal overload. - It includes undervoltage protection, over-current protection, blocking protection, and other safeguards to ensure safe operation of electric bicycles. - The wiring harness features multiple colour-coded wires for different functions; only the required connections are used, while unnecessary functions are omitted without affecting operation, making installation convenient. Use scenarios: - Replacement on a commuter e-bike to improve reliability and safety in varied weather and daily riding. - Use in high-demand or performance e-bikes where effective heat management helps maintain consistent performance and longevity. - DIY e-bike builds where a streamlined, function-focused wiring set simplifies assembly and reduces wiring errors.
