At first I didn't understand it either, but now it just seems like it's way more efficient than most bikes. Yeah you're pedaling all the time, but the pedals turn themselves, so half the time your legs are going through the motions. It's not like you have to be pushing hard all the time, although, I always find myself trying to ride it at a pretty fast pace most of the time. I rode 12 miles today next to my friend on his geared bike and I honestly think the journey was easier for me than it was for him.

I think riding brakeless is the ultimate experience on a fixed gear... That's when it really seems like the perfect invention, you want to speed up, push the pedals, you want to slow down, resist the pedals.

Its just a different experience than any other bike. Different bikes serve different purposes, so it's not like fixed gear is the answer for everything. But for pure enjoyment on a bike, I think it's the best option.
