Show everyone how good you are with the bike. It's nothing special to ride two wheels. The real art is to ride only one! How long? Well it depends on what pro you are! Get on the bike, try to catch the balance and go on the track! Riding only on the plane is easy. Can you adjust the ride on the hill or on unpredictable obstacles? Collect coins along the way and buy a new bike! It's boring to ride a classic road bike when you can ride a unicorn or a harley. Have fun.
