OK, this may seem like a weird question but i can't work out an answer to. Almost everyone who gets on a bike falls in love with them and can't get enough off them. My question is, what is it about bike riding that makes people fall in love with it? Not that thats a bad thing, i love my bike and wouldn't give it up for the world, i just can't work out why. Its so dangerous, yet so much fun. Any ideas?
