Wald has been making bicycle accessories right here in the USA for nearly 100 years. And their Rear Wire Basket, standard issue for paper boys for generations, is one of their most popular items. It attaches over the rear wheel of almost any bike adding ample space for books, groceries, picnic supplies and anything else you'd like to take along or bring home. The sturdy steel baskets are built tough to last a lifetime and they include a built in rack, which is great for strapping on even more gear, or for attaching a rack trunk (sold separately) on top.
Dimensions of each basket: 13 1/2 x 6 1/4 x 11 inches
