Have grownups sit children in their lap. Introduce the lap ride, show parents bounce, side to side, up and down, and roll back.
Then start music, repeat if desired.
Riding my bike down the street
Wind in my hair I feel the breeze
Pedalin’ fast as fast can be
Cruisin’ along look at me
Turnin’ right and turnin’ left
Over the hill, back down again
Falling back out of sight
Havin’ some fun on my bicycle ride
