I have never done a spin class, but what I have seen is far from laid back. Of course, one does not have to go at it like all the others. Kudos to you for wanting to help your child. Does she already ride a bike? If not, not so sure this would be a good introduction. I believe spin class, in general, takes pretty good focus on the pedaling. Maybe not a whole lot of distraction, though. I hope you both do it, and report back. I am interested in how it goes. I would definitely dress in what you like to normally ride in.
