I still don't get it.
"You said If you ride backwards with a BMX using a freewheel, then you HAVE to pedal backwards. THINK ABOUT IT FOR A SECOND."
But you don't "HAVE" to pedal at all. We are talking freewheel, right?
Although it's kinda mean fun to watch you try to figure it out, I'll step in here:
When your wheel turns backwards, the freewheel engages, causing the cranks to turn. If you don't pedal backwards when traveling backwards, you'll apply forward force to the cranks, and your bike will stop. Freewheels can only "freewheel" one direction, otherwise you wouldn't be able to apply force to the rear wheel.
AnOxymoron: I am really enjoying your posts, please keep up the good work. You set the bar pretty low with your OP, and you consistently lower the standard with each and every reply. Very good.
