Ya know, I can dig the artistry of those sculptures and I DEFINITELY appreciate the time and effort that went into their creation. But, I always thought the best bike was one that was made to be ridden, and ridden a lot. Those showpieces are pretty but are about as ridable as the concrete birdbath sitting in my front yard.
Don't get me wrong, I do like them, I just don't consider them to be true, useful transportation.
