http://socrates.berkeley.edu/~fajans/Teaching/Steering.htm To turn a bicycle right, you only need to be able to turn the handlebars left: “Once you begin a right turn by countersteering to the left, you might think that you would eventually turn the handlebars back to the right. Surprisingly, it turns out that you never need to turn the handlebars right. Don’t believe this? Try it. While riding very calmly (perhaps coasting) let go with your left hand and push the handlebars with your right hand. With this handhold, you can only force the handlebars left, but you and your bike will go right.” 16:25
