This project shows a way to bring the groceries from the cash desk in the supermarket into the house. To do so, I designed a stable shopping cart that can be carried on the rear rack of a bicycle. The wheels can be folded down to use the cart at standing height. Beside shopping cart it can also be used as a child stroller with room to store things. No modification at the bike is necessary to use this cart in a simple and versatile way. Simple, because you can easily take the cart on and off the bike. Versatile, because you can think-up many applications. The wheels are nearly 20 cm or 8 inch, so you can drve with ease on streets and sidewalks. Also low thresholds are no problem, that different from the usual shopping cart. The container is made from 9 mm or 0,35 inch thick multiplex board, glue'd and nailed together. All parts of the cart you can buy at the local diy market. I used the castors of an old rollator. The weight of the cart is 11Kg or 24,25 pound. The volume is 50 liter or 13.2 gallon. A building plan, an instruction video and many photo's are making this project easy to replicate.
