Feature: 1. The simple and clear connection of the wiring harness makes the appearance more beautiful. 2. Suitable for two‑wheel electric motorcycles, electric tricycles and other high‑power. 3. 3‑mode controller (more stable, higher efficiency, lower current consumption, longer life). 4. The brushless controller adopts a full‑cast aluminum shell, which has strong heat dissipation, dust and water resistance, and high stability. It provides better protection for the internal circuit and makes it more durable. 5. Universal 36V‑48V, can support two voltages at the same time.
