Core77 introduces us to the Defender 250, a e-bike developed by the German manufacturer Dolas. What makes this design unusual is that there's a third wheel in line with the other two. All three are powered by hub-mounted motors juiced by a 48 volt battery. The rear wheels have independent suspension to allow for a smooth ride.
The design allows the bike to carry a second person comfortably and have room for a storage rack. Alternatively, the extra space can be used to haul a lot of cargo. Owners can attached panniers and a rear rack or just one very large flat rack.
