I forgot to mention, as we were riding our electric scooter past Sanlitun, we got passed by two laowai on a dual sport bike... they were clearly laughing at us on our overloaded scooter with motorcycle helmets, and I could see the rider making pedaling motions as they passed us. Screw them... they had no helmets and no tags and I'd give even odds they didn't have a license either. :(
