--- Comment #5 from thomas thomasgeordjy@gmail.com --- When it comes to learning how to ride with one hand, there are a series of progressions that every cyclist should take. The first step is to pedal up to a comfortable speed while going in a straight line for at least 10 to 30 feet.
From there, lift one hand up, but only hover it a few inches above the handlebars. If you feel that the bike is becoming unstable, you can quickly return the hand to the grip.
