How do you turn on a bike and start riding it?

To turn on a bike and start riding it, first make sure the bike is in good condition and the tires are properly inflated. Next, straddle the bike and place one foot on a pedal in the 2 o'clock position. Push off with your other foot to gain momentum and then start pedaling with the foot on the pedal. Use the handlebars to steer and balance as you ride.
