The Shadow Edge Tube 2.0 makes the Bosch battery pack completely disappear into the frame and ensures an elegant and clear look, but the battery can still be easily removed from the frame for charging. This intelligent lid mechanism has been developed by corratec and patent pending. The integration of the battery reliably protects the electronics from dirt and external influences. The shapely edge on the Shadow Edge Tube 2.0 provides a sporty look and the special design of the edge increases the rigidity and thus the safety of the frame.
