Perfect for everything from a picnic trip to the park to an adventure day with the family, the Trunk Bag RC is what we need for carrying our essentials and then some. It offers a 12-liter payload with a hook-and-loop roll closure that also serves as a carrying handle, and it fits on nearly any bike rack with a width of 60- to 160-millimeters. We like how easy it is to clip on and secure this bike bag, and we appreciate the shoulder strap that makes it easy to carry around when we step away from our ride.
