This thread isn't necessarily about safety. It's obvious why people want a front brake. This thread is more about the aesthetics and energy efficiency of a track bike and freewheel bike.

Can you stop being stupid and read the description and not just the title?

The question is, why do people ride fixed with a front brake when you can have a freewheel and a front brake and the bike will look the same. You would also save more energy with a freewheel, so why would you have a fixed gear if you already have a brake?
