If your Tuttio Soleil01 electric dirt bike is having electrical gremlins – intermittent power, display glitches, or no response from the controller – the main wiring harness might be the issue.

This replacement wire harness assembly is a direct fit for the Soleil01, but here's the key detail: it's ONLY compatible with the display that has an M-key function.

So before you order, take a quick look at your display and make sure you've got that M button.

The harness replaces frayed, broken, or shorted wires and restores solid connections between the controller and other components like the display, throttle, and sensors.

It's made from good-quality wire that resists wear and aging, and it comes with standard connectors for plug-and-play installation – no cutting or soldering required.

Once it's in, you'll get stable electrical and signal transmission, which means your speed display, mode switching, and overall performance should be back to normal.

Easy install, reliable materials, and it keeps your e-bike running smooth without having to replace the whole controller system.
