They have already hit the car, went through the fence 2 times, and hit the trees and swingset in the backyard. They must know how to fall because they have never been hurt bad on the bikes yet. 
They get more banged up on their pedal bikes.
The last time I moved the car into the street to let them ride, someone backed into my crown vic and did $4000 worth of damage.
I love riding with the kids. I need another pit bike though, the neighbors look at me funny when I ride my 200 around the yard. 
I am thinking about going up to mines and meadows at some point with them, has anyone been there? I hear it’s a good spot for the kids.
