This proyect started with a cargo trike chasis without any functional motor nor controller. To make it useful for service we needed to redesign all the wire harness to avoid daily fuse replacement (a ritual with other cargo trike), burnt joints (another common issue) and other dissabled functionalities (front and rear lights, indicator lights, brake light, claxon, key disconnection, etc).

Now the trike is working 6-8hours everyday without any trouble!
