+1. I fixed a kid relative's bike when he was little, instead of using the kickstand, he would just drop the bike sideways, pedal onto concrete (determined after failure analysis). Fractured the stamped cup on the cheap bottom bracket on a one piece ashtabula crank. I replaced, greased, adjusted, and instructed him on why it broke and to use the kickstand.
