NuVinci bike

The transmission of the NuVinci bike is not really a bike: it's about the car.
The N360 NuVinci is a transmission cars packed into the hub of the rear wheel of a bicycle, it happens to be the Edwin Organic bamboo bike (although the NuVinci could be used on any bike). This hub is a small-scale version of a "global" (or automatic) transmission, the same kind used on motor vehicles.
The NuVinci version is only thanks to the elegant interior design and a system of gears, the parent company says it is also used in motorcycles, cars, trucks, electric vehicles and wind turbines.
We try to explain the mechanism:
The NuVinci transmission uses a set of rotating and tilting balls positioned between the input and output components of a transmission that tilt to vary the speed of transmission.
The advantage of a hub like this is that there are no gears. You can shift gears without pedaling, and there is no possibility of crushing the chain and gears - Click the gear and the gear shift in an instant. Bike transmissions have been around a long time, but the NuVinci is one of the first to be quite light and cheap for a practical use. If you're wondering what the revolution of the commuter-bike might look like, look no further insight into the NuVinci hub
