W ith Garreth and Pep, the Catalan car thief, deep in electric hub motors for bicycles, she’d been glad of Inchmale’s call. She barely knew what hub motors were, but Pep wanted two, for extra speed, while Garreth insisted that two were too many. If one of them were to go out, Garreth argued, the extra weight, plus the generator drag, would negate the advantage of the first one. But if there was only one, and it failed, Pep could peddle as best he could, while not expending energy on the extra weight. The clarity with which she retained this, while having no knowledge of what any of it was really about, surprised her.
