You will hear the BikemanforU moan. Heavens, a challenging situation: Brakes or not.
BMX is a great sport. The rider is out doing, in fresh air, getting exercise.
There’s a lot worse things that kids could be doing.
BikemanforU and friends, at the age of 14ish, built their own half-pipe and bikes in their BMX days. Sometimes, I couldn't look. However, it turned out right.
