How functional does a gimmick have to be for it to stop being called a gimmick? Consider down-tube storage compartments for example. They seemed like a novelty at first, but use one for long enough and you might wonder why they’re not on—or in—every new bike. Travis Engel had a similar experience testing the Bookman Volume 800 and Volume 1500 bike lights. They’re loaded with gimmicks, some of which should probably be standard on every light. Still, they’re not quite perfect.
