> The coaster brake also can be prone to locking up the wheels and causing the tire to skid. For kids this is an advantage, since they enjoy putting bikes into a sideways skid.
Damn well it was! I remember we used to play tag on bikes. But when we switched to hand brakes, it became impossible, as you need a free hand and speed control at the same time.
Yep I wore holes in several tires doing skids on my Schwinn when I was a young boy. My father got somewhat annoyed at it but used it as an opportunity to teach me how to change a tire and threatened to withold from my allowance the costs of any more tire replacements. I can't remember if that actually ever happened.
