It seems everyone downplays how dangerous these bikes can be at first.
Im a regular MTN biker and my instincts just do not allow me to ride a fixie safely. Its not the riding it thats the problem its the emergency reflexes that Im most worried about like going over obstacles where you might have to stand up, or quick stops or even turning around to view traffic. These are all cases where I level the pedals out and center my weight. Then theres the whole pedal clearance around sharp turns thing, something I don't want to find out on a hill big enough to show it. And I can skid stop but then it wears a patch in the same spot on my tire! I dont have $$$ to do this.
I know with time I would adapt, but then I have to re-adapt to my Mtn bike? The things Im doing on that are already dangerous enough!
But seriously you guys are crazy.
