It could be really cool with track cycling as a thing in the game where you can play alone or with several on a track that will be cool. perhaps further develop something reminiscent of it. Does not have to be the wild stuff.
But as a cool addition you could make a box or a nice remote that runs with the trainer or Ant + or with bluetooth for the handlebars where you can choose the different maneuvers that you can out on the track just like in reality realized for track races?
sorry for my english tho xD
