Frontal lobotomy?

I've even heard people asking re. mountainbikes 'I saw some guy riding with only a front brake the other day and thought it looked really good (i.e. minimal), do you think I ought to too?'

Now that is really dumb. I can't understand people like that.

That's stupid. One rear brake is good for dirt jumping but mountain bikes should have two for all other disciplines.

Apart from fixed off roaders which are doable on nobrakes, more sensible with one and overkill with two.
