bicycle generator rig 3d model

“Create a 3D model of a pedal-powered bike generator system. Include: a bicycle mounted on a triangular rear stand lifting the back wheel; a drive belt connecting the rear wheel to a DC motor on a small base; wires from the motor leading to a diode, then to a 12V battery with clear positive and negative terminals; and a power inverter connected to the battery. Show an alternate version where the motor directly powers a glowing light bulb. Use clean, realistic materials (metal, rubber, plastic) and simple studio lighting. Keep wiring neat and visible. Present the whole system assembled in one scene.”
