OK, so it’s the only pipe bike I’ve ever seen, but that’s not the only reason it’s the coolest.
Though I do hope that there was a seat, probably an office chair, sitting upon that seat post. Otherwise the rider might be the recipient of an unexpected iron enema.
I love the fact that the handlebar and seat heights are both adjustable. In fact, looking at the elegant curve of the main pipe, it seems that the builder was a talented engineer. It seems that the repurposed pedal car or industrial cart wheels are the only things originally vehicular.
While this a fine object, I’m not sure it’s worth the asked $150 opening bid. Not to mention another $150 for shipping. This is a rare case where uniqueness does more harm then good to its value. After all, it isn’t a real bike and was probably rarely used as such even when new.
