How great are boxes? Fillable, stackable, durable and invented before the wheel!* Now, a mere 6,000,000 years after the first box, we’re proud to present a box made specifically to haul your stuff around on your bike! The Pure Cycles City Box bolts right onto the top of a front or rear rack and will take whatever you can shove in it from A to B (and on through the alphabet) snugly and securely. Made of wood and stained a deep, dark woodsy green.
