I can't imagine that holding a static standing posture like that would feel good on your lower back after a little use. The smaller wheels will send all the shock in the road up your straight legs to your back. Unlike the Segway, which has the handle to help balance and direct motion, you can't shift your weight on this without switching directions. The majority of momentum change on this device is forward/back, it's better to compensate with a sideways posture like on a skateboard.
