The CARRYME DS is the dual speed version of CARRYME.  It has ATS SpeedDrive with 1:1.66 ratio which speeds up to 50% speed than the SD version.  It weighs only 9.2kg and will fit in a 93 x 32 x 25 cm bag in seconds, making it extremely easy to carry, transport, or store. It really shines, however, when you unfold and ride it. This is without a doubt the best solution to getting around the city without the hassles of waiting for traffic, looking for parking spots and paying for gasoline! Of course, you get a great workout at the same time and do your part to preserve the environment.
