Build your own panniers made easy
aluminium boxes, are produced by many different companies. Unfortunately most of the time they are so expensive, that not everybody can afford them.
20 liter jerrycans, cut into half and fixed using messing hinges can be used as panniers.
ammunition boxes from the army. Those can be cheaply bought online but their weight is around 10 kg each.
Sometimes one can buy aluminium cases on scrap places for the kilo price of aluminium. Those can easily fit to the bike using old pipes or metal bars.
You then bend two metal bars each to the form of an U. The black metal U has to reach from the left food peg past the numberplate to the right food peg. The red metal U has to be attached to the bike frame using metal angles at the blue point. At their end, the red U holds the black U. Now one can drill three holes into those metal bars, to get the 3 green dots, needed to attach the panniers. Just three more screws, some washers and wingnuts to hold the panniers. Finished.
