Know before you buy
The Banjo Brothers Expanding Rack Top Bag is designed to mount securely to most standard rear bicycle racks using a universal strap system. As long as your rack has a flat top surface, it should be compatible.
No, this bag is not waterproof. While the ripstop and ballistic nylon construction is durable and can handle light splashes, it is not designed to be submerged or used in heavy, sustained downpours without a rain cover.
The thick padding acts as insulation, which is great for keeping snacks or drinks cool during a short commute or a quick ride to the park. However, it is not a replacement for a dedicated hard-sided cooler and will require an ice pack for longer trips.
Yes, there is an integrated clip on the back of the bag specifically designed to hold a rear safety light, which helps improve your visibility to drivers in low-light conditions.
The bag offers a total capacity of 14 liters. When expanded, it provides enough extra room for a change of clothes, a light jacket, or a small camera setup alongside your daily essentials.
Yes, it is fully compatible with e-bikes, provided your e-bike is equipped with a standard rear rack.
