So you want to turn your existing bicycle into a cargo bike? BikeBuddy has you covered. It is a detachable bicycle sidecar that can be attached to your BMX or mountain bike. It can be used to carry your groceries, pick your kids from school, or give a ride to your loved ones.
BikeBuddy also has a canopy attachment for bad weather. Like what you see? This project is currently on Indiegogo.
