Spurcycle, the company that makes our favorite bicycle bell, makes a saddlebag, too. And at first glance, it looked simple and even stylish: a black fabric sack, shaped like a lunch bag, that you fill, fold over, and wrap tight with a Velcro strap that also loops through your saddle’s rails. We have our worries about Velcro, but after a few weeks of testing, we saw no sign of abrasion on our bike shorts. However, on longer rides (four or five hours), the bag tended to slide out of its Velcro confines. After the first instance—and thinking the problem was user error—we double-checked the instructions on the Spurcycle site and reinstalled the bag, but it kept unraveling.
