Harness Studio

A free design tool that turns controller, throttle, frame and accessory choices into a wiring plan with wire gauge, fuse suggestions, a bill of materials and a shareable diagram.

Status: live and free to use. Starter data covers the 2023 Light Bee X; more bikes are added as the wiring is verified.

What it does

Compatibility

Catch incompatible controller, throttle, accessory and frame combinations.

Electrical rules

Generate wire-gauge and fuse suggestions from verified design constraints.

Build package

Create a BOM, shareable diagram and PDF for review before anything is built.

Designs are a starting point, not an engineering sign-off. Verify every wire, fuse and connector against your specific vehicle before building.
