Conclusion: To make a prototype is not a rapid job. Finding the right sizes is the main thing. The folding system of the legs was the most time consuming part. The legs are standing slightly forward and backward in order increase the stability. I made strips on the box to fix the castors in the high position. To keep them flat agains the box. The volume of the cart is enough to contain food for 2 persons, shopping once a week in the supermarket. Everyone is free increase the volume of the shopper cart by making the box wider or higher. My wife can handle the weight with ease. All in all, it was a challenge to find a new way to shop without using my car. People turn their head, seeing a strange object on the back of my bike. Using a bicycle is always eco - friendly.
