We have two 6-speed analog C-lines that spend most of the summer in the aft cabin of our Pearson 38. We store them in Brompton Transport bags, which roll up and store in a small handlebar bag. When folded,they both fit in our 10.5 foot Achilles dinghy.
Brompton’s engineering is ingenious. We bought them as “land tenders” for the sailboat, but are using them more and more for trips and everyday riding. In May, we packed them in B&W Foldon cases, airlined to Heathrow, took the train to Lancaster, and rode the Way of the Roses cycleway across England on our Bromptons. These are real bicycles.
