French designer Jérôme Blanchard has an interesting concept bike posted on Coroflot. He has several other bike designs in his Coroflot portfolio, so take a look. Via Core 77.

Speaking of Core 77, they have posted a few bike related entries lately. This one about the “Super Contemporary” show in London features a bike with some kind of force field umbrella or something. I don’t know; maybe I am missing something. Another recent Core post points out some of the bike rack designs from Creative Pipe. I mentioned in an earlier post that their Horseshoe rack is one of my favorites as well. While I am still talking about Core 77, I will mention that they are apparently putting out a bike this summer. Designed and hand-built in New York…it will be interesting to hear who is making it for them.

I have mentioned Brano Meres’ bikes on the blog a few times before. He has a couple of new bikes that he recently completed. Check out his next generation bamboo MTB frame and a new titanium riveted frame “with parts made of laser cut and bent titanium sheets.”

Designboom posted an electric racing bicycle concept by art center student Anthony Cioffi. Well, the post title says it is a bicycle, but apparently that is a typo because it is really a motorcycle concept. Oh well, it made me look…and Anthony’s site is pretty interesting.

I spotted the Ubicycle public bike service system concept while thumbing though the May issue of Metropolis magazine. The modular racking trees with solar canopies collect the energy to power the units.

Jasa recently completed a pretty nice restoration of a classic 50-year-old Goricke bicycle. Take a look at his before and after pictures.

3DVIA is running a 3d modeling challenge. Create a helmet model with 3d software and upload it by June 14th for a chance to win a 32GB iPod touch. Yeah, I know… the contest is open to any type of helmet, not specifically bicycle helmets. There are only a few entries at this point though, so your chance of winning is pretty good if you have a slick bike helmet design that you are willing to share.

Product Design and Development magazine has an interesting article about composite aluminum reinforced with carbon nanotubes. The article points out the density of the CNT-reinforced aluminum is about one third that of steel. “With its combination of high strength and low weight, Baytubes-reinforced aluminum is a welcome alternative to steel, expensive specialty metals such as titanium, and carbon-fiber-reinforced plastics.”

Finally, I will mention that London Cyclist recently compiled a top 50 list of cycling blogs. According to the post, the rankings were based on “a number of elements such as Google Pagerank, Twitter Rank, Alexa Rank, number of comments and Technorati Authority.” I was happy to see that Bicycle Design showed up in the number 11 spot right between Cyclelicious and Bike Commuters. After seeing all the other blogs on that list, I feel like I am in pretty good company. Thanks London Cyclist!
