A Continuously Variable Transmission (CVT) for use in applications where a transmission is desired to change the speed of the motor relative to the speed of the final drive. The CVT has a set of chains or belts that are mounted around a set of pins set in radially cut slots of a set of spindles so that the pattern of pins are able to expand and contract radially around the CVT axis via these slots. Sprockets that freely spin in either direction unless a chain or belt has fully seated on at least one tooth are arranged on the pins so that only one sprocket engages one chain or belt allowing for smooth ratio changes while the load in engaged. The spindles share a set of springs that act to return the transmission to a higher ratio at moments the load is overcome.
