Looks pretty cool. The other thing you might think about is the fact that some people set up their (outside) bikes in a stationary trainer as a way to use them inside. This doesn't seem compatible with that sort of thing, but it seems like you might be able to modify it for that. (It would have to be easily detachable, since people would want to be able to take their bikes outside without too much trouble) I'm not sure what the ratio of people is who own an xbox or playstation and also own a home exercise bike versus a stationary trainer for their bike, just in terms of cost (cheaper to use a regular bike you already have, or to buy both pieces rather than a nice home exercise bike) that the market would be bigger for bike+trainer than home exercise bike. I only know of one system, but I've never tried it out: http://www.tacxvr.com/en/products/fortius-multiplayer http://www.tacxvr.com/en/products/fortius-multiplayer -it's very different from yours though. At any rate, it's another pretty big market you may not have considered....
