This is my theory: When the moving bike leans to one side, there is additional force created between the bike's wheels and the ground other than that already there due to the bike's weight. That centripetal force, and the friction with the ground, sort of force the bike to steady itself in an upright position, countering the force willing it to fall down. The stationary bike does not have this centripetal force.

I think it has something to do with its centre of gravity.

I think the flood of air particles that the moving bike pummels through keeps the bike straighter due to the pressure on both sides. (my guess)
