  • VELOCIPEDIA – A NEW TWIST ON DREAM BIKES.

    Velocipedia is a virtual museum of the world’s most unlikely bicycles

    It’s amazing to see how many variations are possible on the basic form of the bicycle.

    Think how different road, mountain, cruiser, and BMX bikes are for example. Then of course there are all sorts of cargo bikes, multi-seaters, creative home-made and customized machines unlike anything else.

    As unique as some of those bikes are, they are outdone by the creations “documented” by the Velocipedia project. It sets the bar for inventive reinterpretation of the humble bike impossibly high, with the emphasis on “impossibly”.

    The only thing everyone got right was the number of wheels.

    It all started when Gianluca Gimini, a designer based in Bologna, Italy, was intrigued by a friend’s funny story about hopeless attempts to draw a bicycle from memory.

    He challenged others to do the same, and soon collected impromptu sketches of bicycles from hundreds of people. A few were quite accurate. Many, many more were comically wrong.

    Gianluca gave himself the job of actually rendering the bikes with 3D imaging software, exactly as they had been depicted, and the Velocipedia project was born.

    It’s an amusing idea, a very impressive labor of love, and the results are delightful.

    Velocipedia bicycles are strange, funny, wonderful creations. At first glance, they look like they would be a hoot to get around on. On closer inspection you realize many would be impossible to ride, even deadly dangerous.

    Imagine taking these dream bikes for a spin…

    Veloicpedia childrens contest winner bike renderingOne Velocipedia exhibit included a contest for children, inviting them to draw the bicycle of their dreams rather than the usual request to draw a bike from memory. The kids produced some amazingly inventive visions of bicycles, and a few won a print of their fully rendered creation as their prize. The dream machines Gianluca brought to virtual life for these kids are among the most interesting of the Velocipedia collection. See more of them here on Gianluca’s Facebook page.

    What Velocipedia reveals about people

    Gianluca found some interesting psychological phonomena in the sketches he collected. It turns out psychologists use similar experiments to work with memory, and there is a documented tendency for people to fill in the blanks when they think they remember something clearly but in fact do not.

    A few “mistakes” showed up in many of the sketches, and interestingly, they split along gender lines. Of the people who connected the chain to the front wheel instead of the rear, more than 90% were female. Their drawings were much simpler than those of males. The guys would get things wrong and realize it, then keep adding details to try and correct it, ending up with complex drawings with lots of mistakes!

    Hmmm…

    Check out this video for a closer look at the work that went into the Velocipedia creations – Gianluca compressed over 9 hours of painstaking 3D rendering into 4 minutes!

    Like bikes and art? This video is a fascinating look at the work of a variety of artists who focus on bicycles – Gianluca is featured in a segment in the middle.

  • Bikes for Women: Looks can be deceiving

    When I first started building bicycles for women some 25 years ago, it took only a quick glance at a man and a woman of the same height to see that her legs were longer than his.  Her shorter torso was clearly the reason why she felt “stretched out” on a bike and had to endure discomfort in her shoulders and back. So Terry bikes were built with shorter top tubes on all sizes to address this concern.

    Around 1990, I decided to get a more analytical and less anecdotal about the root causes of some women’s discomfort while riding.  There’s a lot of information about men’s and women’s anatomy and I was looking forward to finding out just how much shorter a woman’s upper body was proportionate to a man’s.  Guess what?  Women have proportionately longer arms and trunks than men.  Looks can be very deceptive, thanks to women’s higher waist lines.

    Yet, women’s discomfort on bikes was very real. But what was the underlying cause?  We were doing the right thing but for the wrong reason.  We needed to know the right reason.

    Enter Laura Lund, then working on her Masters in Mechanical Engineering-Bioengineering at Carnegie Mellon University.  She did some research and came up with some possible causes for women’s discomfort.  In doing so, she confirmed why our designs were working.

    So what was going on? It has to do with the distribution of body mass and the location of the center of those masses. They differ between men and women. More of a woman’s body mass is in her trunk than a man’s. And, speaking in simple terms, it’s higher on her trunk than on a man’s.  Think of it like this: if you put a five pound weight on your lower back and then bend over, it will be a lot easier than if you bend over with the same weight on your shoulders.  Your total weight is the same in both cases, but in the latter case, you’ve moved the center of that weight up and away from the muscles that are doing the work.  This higher “center of mass” means more effort is required by the lower back muscles.  A similar situation exists in the arms with regard to the forces exerted on the rider’s shoulders.

    Add to this the fact that women tend to have smaller muscles than men to support these forces. Not a good scenario!

    But the story doesn’t end there.  Stay tuned….
