I basically have no riding experience, beside motorized scooter. Which is what I am currently driving. I was looking into the Galaxy XTR a bit, but it doesn't really seems like it could carry a fussy girlfriend if you take my height in consideration! What inspired me, guess the same issue you have in Shanghai: cars are useless and bikes are to slow! Furthermore both my office and home address are in central area of BJ, so 京B already wouldn't be enough.
