Restore Your E-Bike's Central Nervous System
The main wiring harness is the core electrical communication line of your e-bike, seamlessly connecting your LCD display, throttle, brake sensors, and motor controller. If your original wiring has been damaged by extreme wear, accidents, or electrical shorts, this Official Burchda Replacement Harness will restore your bike to peak factory performance.
Premium OEM Features:
Genuine Factory Part: 100% authentic Burchda component, ensuring exact voltage matching and signal integrity for your specific e-bike system.
Waterproof Connectors: Equipped with color-coded, IP-rated waterproof quick-disconnect plugs to protect your electrical system from rain, mud, and moisture.
Durable Shielding: Encased in heavy-duty, abrasion-resistant casing to prevent wire chafing against the bike frame.
🛠️ Guaranteed Plug-and-Play Fit (How to Order):
Because different Burchda models feature unique frame geometries and controller configurations, their main wiring harnesses are specifically tailored and are not interchangeable.
To ensure you receive the exact harness for your bike with the correct length and plug connections:
Select Your Exact Model: Please choose your specific e-bike model (RX80, R5, HC26, RX30, U8, or Y3) from the dropdown menu above before adding to cart.
Unsure Which Model You Have? If you are uncertain about your bike's exact version or production year, please contact our customer support team with a photo of your bike and original wiring harness before purchasing. We are here to help you get the right part the first time!
