Continuously Variable Transmission

Properties

Example #Bike
- A Continuously Variable Transmission (CVT) on a bike functions by using a system of variable-diameter pulleys connected by a belt, allowing for seamless gear shifts across a wide range of ratios without any distinct steps between gears, essentially providing an "infinite" number of gear options that can be adjusted smoothly while riding by twisting a shifter; this means you can transition between high and low gears at any point without needing to click through specific gear positions like on a traditional bike.
- NuVinci continuously variable transmission - Wikipedia
  - The NuVinci CVT replaces derailleurs and other internally geared hubs, and provides a gear ratio range of about 350%, similar to that on bicycles with 8- or 9-speed hub gears, or with double chain rings (most racing or fast road bicycles).[
