If I use the wheel it's at the end of the week on Thur or Fri when I'm getting tired and want an easier day before a bigger ride on Sat. When commuting I usually just pedal as hard as I feel like. I average between 180 and 220+W, usually higher when I'm fresh and lower towards the end of the week. If I use the electric wheel I don't think I pedal any differently, I just go faster.
