Take one push bike (mountain bikes are good for this)
Find a patch of loose gravel and ride into it at moderate speed, turn gently at first to get used to the sensation of the front wheel doing strange things, then as you get used to it apply more turning force and speed. eventually you can build up to speed, turning and braking sharply. It's a good way to find out what happens if your front wheel washes out and therefore helping prevent embarrassing trouser accident/lowside moments.
