like they say, it's the rider not the bike, if you lack the skill to ride a bike, then brakes or no brakes your going to F up on day and hit something or get hit because of your own stupidity and inability to ride a bike properly.
most of my friends here ride brakeless and they can control their bikes just as much as you can with your precious brakes. In fact i have a friend here who rides 2 brakes and i ride faster and harder and safer than he does, why? because i know how to ride in an urban environment.
listen to shants, he said it best earlier.
