The gyroscopic effect will help, true, but that's not enough, especially at low speed. Two-wheeled vehicles are dynamically stable...basically, you steer the front wheel back and forth just a little to keep the bike under your center of gravity. You turn by moving the wheel to one side, "falling" toward the inside, and then "catching" it with the wheel as you make the turn, and you end the turn by returning the bike to just under your CG.
As such, you can ride a bike on a treadmill just fine without falling over...it will probably just take a bit of practice to get used to the feeling, and to steer correctly.

Well, I suppose if you had SUPER-massive wheels with a lot of angular momentum, and very grippy tires...:laugh:
