Roll at curb at moderate to slow speed.

Lift front wheel over curb height.

Next, lift back wheel accordingly.

Do this about fifty times until your rim is nice and dented.

Have your parents by you a new wheel set.

Repeat from step one.

Repeat from step one again.

Your parents will now tell you if you bend one more set of wheels you'll be grounded and can't have a bike anymore.

After that news you'll be bunnyhopping up picnic benches in no time.
