what if that ease of use what in a bike type design. no need to peddle. it could sense shifts of weight in your seat to tell if you wanted to move forward or reverse, left or right, or brake (like with the segway) no matter how slow you went, no tipping.. yet a design more apt for higher speeds and better control should you need it.
the hardest part would be getting onto the bike.. once on.. a toddler could ride it-- no need for training wheels.
whether peddling or not, you don't need a balancing system on a bike. You already subconsciously do all these things to control the bike. It's pretty much impossible to fall off a bike unless you hit debris (balancing wouldn't help you here), you turn way too sharply for your speed (wouldn't help you here either - can't counteract physics), and so on. This "balancing" system would just upset your natural sense of balance and make it weird to bike. Oh, I never needed training wheels

. In fact, I think training wheels would slow down the process of learning how to balance yourself on a bicycle - and in some cases the person may never completly master it.
Now, one application that would make sense is for it to balance the bike when it is moving slowly or not at all. This would give you more control at lower speeds where the gyroscopic effects of the wheel don't help out much. Again though, it seems a waste of resources to me. The power should go into speed and distance making the bike much more practical than a segway could ever be.
Think about it: If you had a bicycle that could reach 35mph and keep that speed for 10 miles, then why on earth would you ever take your car to do little things like go to the bank or pick up a bag of milk?? You could let the car rest for those times when the bike wasn't practical (bad weather, winter, etc) and save thousands in gas and repair costs. If I had such a bike and also had a car I'd never use the car except on weekends to have fun with my friends.
