Beginner rig question -- unicycle pedal

[medicalart]

What's the best way to set up a leg and foot to pedal a bike so that all move in synch? I'm thinking that I'd use IK on the foot and leg bones and target the foot to the pedal. Would that work? Would you use bones in the pedal, or just set the pivot points and animate? Thanks for any tips.

Setup the unicycle so that the pedals are separate objects that are parented to the main wheel. Use a simple expression to rotate then in the opposite direction of the big wheel.
The IKGoals for the legs can be parented to the pedals.

Wouldn't the rotation be in the same direction? Thanks for guidance.

If the pedals rotate opposite of the wheel theyre parented to they will stay level. :)
