Alex Moulton describes his bicycle concept as the "Advanced Engineering Bicycle".
The "Art Bike" by Thick Bikes, is, as the name suggests is heavy on the Art and, I suspect, light on engineering. I use the word "light" in the metaphorical sense of course, as it weighs in at over 40lbs or 18kgs.
Also, unlike Alex Moulton's bicycles, which are very finely silver or bronze brazed, the Art Bike is rather crudely welded. Still, it is quite spectacular looking and might attract more attention (and just as stealable) as a Moulton.
Amazing. Well spotted. Brilliant. That has made my day!
