Hmmmm. It does sound like the Pelaton just would not be a comfortable fit for you, but how much have you ridden it to see for sure? There is no rule that says once you moved components from one bike to another that you couldn't move them back. You have an opportunity to experiment, why not take it? (Just don't do anything irreversible.) I think you are in a position where you can't make a bad choice. Have fun.
