Posting has been light this week, but I want to quickly pass along a few links that I have run across lately. The Core77 blog featured this “electric bike train” concept from the Coroflot portfolio of Jiang Qian. The concept is intended to be modular so the bike can be used individually or strung together.

A reader, Jim, sent me a couple of interesting links that I want to pass along to all of you. The first is an article in Design Engineering magazine about the development and engineering of a Devinci downhill bike. The amount of data they collected to measure forces at various points on the bike is [...]

Some of you may recognize this chainless bicycle design. The bike received a lot of press coverage when it was new in the early 80s and was even featured on Good Morning America at one point. The bike’s designer, Steven Tidcomb, sent me a link to a page on his website, which provides some historical [...]

All morning I have been hearing the news that the U.S. national average for a gallon of gas topped the 4-dollar mark. Most people don’t seem all that happy about that milestone, but climbing gas prices are certainly something you won’t hear me complaining about.

The bike will be launching in September and they showed a model of the frame at the Salon du Cycle in Paris last year. The company worked with [...]

I usually refrain from posting pictures of myself, but I will make an exception today. Here I am looking very serious while working hard to bring you the absolute best content that I can find on the subject of bicycle design. OK, maybe that is a stretch, but this picture of me staring blankly at [...]

I like to mention bike content in general design magazines when I see it, so I want to point you to a Dwell blog post about handmade bicycles. The post dates back to February, but it was new to me when I discovered it today, so I assume some of you missed it as well. [...]

I don’t have time for a full post today, but I want to quickly mention the new 2009 redesign of the Dura-Ace group. Overall, I think the 7900 series Dura Ace group looks good; I especially like the new brakes. The new crank, which includes a compact option, looks nice as well. I like the [...]

I posted about Evan Solida’s Cerevellum concept in December of last year. If you didn’t see that post, check it out before you read on and take a look at the Cerevellum website to familiarize yourself with the concept.One of the distinctive components of the modular Cerevellum system is the Hindsight feature, which allows …

Check out the Cannondale design sketchbook for a new entry. These three urban bike concepts were a collaboration between the in-house Cannondale design team and D-Tank, a design studio based in Barcelona. The guys from D-Tank studied transportation design at the Elisava Design School with Torgny from Cannondale and in recent years they have done [...]
