POLICE yesterday issued a reminder to owners of motorized personal transporters, such as the two-wheeled Segway and electric unicycle, that they should not ride them on the roads.

Though there are no laws against doing so, Sun Guofu, a spokesman for Shanghai’s traffic police department, said that in the interest of personal safety, riders should limit themselves to parks and other areas that are free from traffic.

“By law in Shanghai, all personal transport vehicles, whether motorized or not, must be licensed to travel on the roads. As no license is needed for these new machines, they cannot be classed as personal transport vehicles,” Sun said.
