The retrofit adapter, which is currently offered by Focus and Conway, acts as a spacer for the large Powertube integrated in the down tube. Advantage: You can now carry the 500 Bosch battery on long bike tours. This makes the rucksack around 600 grams lighter. Focus provides the six centimetres of free space in the Jam as a compartment in which small parts such as a tube or other items can be stored.
