I used to have a stationary bike. I hated it. It was boring. Seriously. But this, THIS might be something to consider. The RealRyder ABF8 mimics actual outdoor biking. Because its frame articulates, it allows the rider to lean and steer as he/she works out. The seat and pedals adjust too, just like the real thing. Not TOO much more expensive than a very good treadmill the RealRyder ABF8 will set you back $1,995.
