👉 Pinionless is a concept in automotive engineering that refers to an arrangement of gears and components around the wheel hub without the use of a pinion. This design is often used in motorcycles, where the gear ratios are adjusted by adjusting the speed of the rear wheels. In summary, a pinionless arrangement involves using only simple gears and a few pulleys to control the rotation of one or more wheels, rather than relying on an external pinion or other gears for synchronization. This approach simplifies
