Biking is not only possible on a bike. You can also bike in the air, even though you won’t get as far as on a real bike.
Go lie flat on your back and move your legs in a circle in the air, as if you’re cycling. Keep this up for 10 seconds.
Repeat this exercise 3x

Watch out:
Exercising should be fun and it should make you move better. Does it hurt during the exercise or do you feel uncomfortable? Then tell this to your parents / caretakers and stop the exercise.
