While I was in Philadephia over the summer I was amazed by the number of folding bicycles. About half of all the bikes I saw were folders. Of course they make eminent sense for urban dewellers. I’ve always been interested in “packable” bicycles, and have a thirty year old three-speed folder gathering dust in my garage. The concept has come a long way since then! Over the holidays I bought two Dahon Speed D7 bikes for $299 each. They’re an exquisite bit of engineering for the price. The principal flaw with the older design, a telescoping seat post, has been replaced by a single long piece. The 20 inch wheels are a nice compromise, the components are good, and the road feel is solid. Folding the bike takes less than a minute, and two of them will fit in the trunk of a small car!
