Create this project yourself with sheet material cut to size by TOSIZE.ie!
My homemade cargo bike had to get a nice box. Strong 9.0 mm plywood with waterproof vandal-proof layer, so concrete plywood! And for the bottom plate still anti-slip, which is very safe.
DIY: create a container for a cargo bike
The bottom plate was the base, a few corners were still there until it is nice. Then mount the backrest at an angle of 10 °. Make the front panel on the front beam of the bicycle frame in the same way. Then the sides, all I really had to do myself was saw off the bevel. It was nicely marked after trial assembly. Then drill many holes and mount with seat angles and m6 lock bolts and adjusting bolts. You have to finish the open edges of the betonplex I used rambo armor paint, 3 coats, colorless.
Bake accurately to size
The tray is 60.0 cm wide, the bottom 80.0 cm long and about one meter at the top. Height container 50.0 cm
