Mrs. Armitage on Wheels by Quentin Blake, 1987.

Mrs. Armitage loves to ride her bicycle with her dog, Breakspear, running alongside.  However, she sometimes runs into difficulties that require some minor repairs to her bike, and she can’t resist the urge to tinker further.

The more she thinks about it, the more ideas for improvements she has.  Each idea starts with the words, “What this bike needs . . .”

But, Mrs. Armitage goes well beyond what the bike really needs.  Beyond adding a seat for her dog and room for her lunch, she gradually turns her bicycle into a crazy, unwieldy contraption.

Was adding the sail and anchor where she went too far, or did she reach that point long before?  Even after she trades what’s left of her bike for some skates, one has the feeling that her tinkering is far from over.
