From an earlier post:
All the great thinkers have obsessed over the benefits of walking to the act of thinking, and it occurs to me that perhaps the cause of this has to do in part with the rhythm which the regular steps present. I have found the same to be the case with the fixed gear machine; the unbroken cadence that must be maintained presents also an unbroken cadence for the mind to follow. Even when stopped, the effortless trackstand converts what would elsewhere be a gap in the experience into an integral part of the seamless whole.
