My Nirve Street King is perfect for me. The bike is 49 lbs, but with the three speed internal it make up for the weight. The short apes keep my hands on a good position, my back is straight. My seat is set low. I can ride that bike 20 miles or more, no problem. When I ride my GT I-Drive 10 miles with the seat up and I'm leaning forward over the handlebars my hands go to sleep, It weighs 33 lbs. All my Dyno's & Nirve's are set for comfort & style, Weight is not a factor, that's what gears are for!
