An adjustable crank assembly is provided. The adjustable crank assembly includes a crank arm having a surface with a plurality of notches, and a retention block that partially houses the crank arm and allows the crank arm to slide along an axis relative to the retention block. The retention block includes a clamping block and a locking pin, both of which being adapted to selectively engage the crank arm when the retention block is placed in a locked position, and a locking lever for transitioning between a locked position and an unlocked position. The locking lever provides a compressive force to the clamping block when placed in a locked position and a retracting force to the locking pin when placed in an unlocked position.

A pedal cycle apparatus is disclosed in which a foot of a medically incapacitated user thereof engages a pedal for moving the pedal orbitally about a rotational axis of a crank hub. The apparatus includes a crank arm having a proximal and a distal end, the proximal end of the crank arm being rotatable about the rotational axis of the crank hub. A fastener fastens the pedal relative to the crank arm at a selectively variable radial distance from the rotational axis of the crank hub. The arrangement is such that in use of the pedal cycle apparatus, the foot of the medically incapacitated user engages the pedal so that the pedal moves orbitally about the rotational axis of a crank hub. The pedal rotates about an axis of rotation which is disposed parallel to the rotational axis of the crank hub such that selection by the user of an optimum radial distance of the pedal from the rotational axis of the crank hub is permitted.
