The disclosure relates to a continuously variable transmission (CVT) unit. The CVT unit comprises a first drive element that is rotatable about a first axis and a second drive element that is rotatable about a second axis parallel to the first axis, wherein the first drive element and the second drive element are movable relative to each other in a direction transverse to the first and second axis. The CVT unit further comprises first coupling elements provided at a constant first radius from the first axis and at a variable second radius from the second axis, for transferring torque between the first drive element and the second drive element.

A bicycle crankset includes a chainring, a spider, and a crankarm. The chainring has a disk member and a plurality of teeth on an edge of the disk member to engage a chain. The spider is connected to the disk member of the chainring, and has a connecting bore and a plurality of recesses on an edge of the connecting bore. The crankarm has a plurality of protrusions to engage the recesses of the spider. The connecting bore is eccentric relative to the chainring, and the crankarm is able to be connected to the chainring in different angles by engaging the protrusions of the crankarm with different of the recesses of the spider to provide various paths of motion of the chainring.

A bicycle crankset, which is adapted to connect to a chain, includes a chainring and a crankarm. The chainring has a plurality of teeth, a plurality of connecting bores of first noncircular motion path, and a plurality of connecting bores of circular motion path. The crankarm has a plurality of connecting arms to be selected to secured to the connecting bores of first noncircular motion path or the connecting bores of circular motion path. The chainring provides a first noncircular path of motion when the connecting arms of the crankarm are secured to the connecting bores of first noncircular motion path, and chainring provides a circular path of motion when the connecting arms of the crankarm are secured to the connecting bores of circular motion path.
