I had a chance to ride a simple old beach cruiser last weekend, and I enjoyed the riding position it offered in terms of being very upright and comfortable. I have been riding in a more downward position with a back-pack, and have not really been enjoying it. I was thinking of looking into something that will offer me (tall, 6'4", typically riding a 61cm bike) a more relaxed position and that will accommodate a rack so I can get rid of the backpack. We don't have any covered bike parking, so it would also be outside a lot, and therefore I don't want to spend a fortune on it. Any suggestions on what I might look into?
