A crankset for a pedal-driven vehicle has a frame with a bottom bracket shell. The crankset includes a crank arm rotatably mounted to the bottom bracket shell of the frame; a spindle operatively connected to the crank arm at an end spaced-apart from the bottom bracket shell and rotatable about a spindle rotation axis. A stationary member fixedly mounts to the bottom bracket shell. A rotatable member operatively engages the spindle and is configured to engage the spindle in rotation. A connecting assembly operatively engages the stationary member and the rotatable member. The connecting assembly is configured to engage the rotatable member in rotation upon rotation of the crank arm about the bottom bracket shell. A pedal angular control assembly operatively connects to the spindle and is configured to control an angle of a pedal according to an angular position of the crank arm during rotation.
