Cycle insurer ETA has a story about a nifty tag-a-long trailer for cyclists. Wooden Widget, who already produces small, collapsable boats, has created the Foldavan. Think of it as a pop-up for bikes.
Additionally, ETA commissioned the development of the Qtvan. It is a more rigidly constructed tag-a-long more in the vein of a teardrop but for bikes.
I’m thinking Qtvan for touring and Foldavan for endurance racing. No? In the immortal words of Scott Thigpen, “Are you trying to win or something?”
