Awwww. Get a life.
I don't own an "alternate" bike. I don't have the mechanical skills to build an alternate bike. I wouldn't personally RIDE an alternate bike (other than a recumbent trike, possibly
) but....
I think they're pretty fun looking. I consider these bikes and their builder/owners to be interesting, experimental, creative and intelligent. Sure, the bikes would be harder to build, harder to ride, requiring more creativity and drive to ride. But why not? Just because it's something you wouldn't do doesn't mean that it has no value.
Kudos to each of them! (and envy - wish I had that much time and energy to spare...)
