In fact no direct ab work unless you are doing A LOT of back/hip extension work like squats and deadlifts several days a week.
On a bike you are already in a hunched, spinal flexion position. Crunches are the last thing you need. If you feel you MUST do ab work, stick to things like planks/bridges. I wouldnt bother though.
No crunches please.
