As one of the strangest designs out there, the GT Mileno can switch from an urban bicycle, cruising the city streets, to a bicycle that’s used for carrying cargo. Whichever its purpose, it seems complex and unlike any other bike on this list. It has a module that fastens in the front. Its two powered wheels ease the strain of the bike when it’s fully loaded with gear. If you’re someone who’s constantly carrying around a lot of gear with them, then this bike might be suitable for you (Road.cc).
