Move at a slow waling pace.
pull on both brakes and pull a little endo.
When the back wheel hits ground again pull back and put your right foot on the wheel. put pressuire on the bike so its almost side ways right, and your left.
At the same time as when you push let go with your left hand and the bars will turn 180
Try to balance. This is very complicated and will take time to get good at.
Now bring back the bike to you and take your right foot off the tire and put the bike nder you.
Place your right foot on the pedal and ride, ride away!
