Just for comparison, check out the difference in length between the Green Weenie and the new Red bike. The new one is great fun and a lot faster, but not quite as comfy as the MUCH longer wheelbase green one. At least now I have one I can take anywhere (it will actually fit inside the Zuk) and still have the green one for touring. The red bike is also from Cycle Genius, called the s24. It evolved in to the CGX. short wheel base, high gears. The term used to describe it is " nimble". Means if you pull the handlebars about an inch it will dump your ass. Fun though.
