A classic wheelie barrow is a traditional trailer designed to be attached behind a bicycle. This type of trolley is usually designed for transporting children or cargo and offers basic features such as a rigid frame, a protective cover and seats with seat belts. Traditional behind-the-wheel carts are affordable and are suitable for occasional trips or for transporting belongings. They offer a stable and safe ride, but may lack advanced features such as suspension or adjustable seats that multi-function or jogging models offer.
