Are you using the same pedals / cleats / shoes as you do on the road bike ? also is your pedalling technique the same on both ? I know on the indoor bike I have more thought time as not concentrating on cars etc and i was thinking more about my pedalling technique on the indoor bike like trying to make it a circular motion but having read an excellent book called the Midlife Cyclist it has a section on pedalling and how the pull up that some recommend is a total myth and can cause injury. Defo worth a read.
I know don't think about pedalling as i don't on the road bike - its just a natural movement.
