Just bought a Motobecane Grand Touring bike. I learned it is called a mixie. Can anyone help me identify the year of manufacture by the following info: It is a 24 speed, on the fork it says '888 Vitus', It had Weinmann center pull brakes the color is gun metal gray, The shifter says 'Suntour ARX', On the sprocket it says 'Stronglight', The wheels are Weinmann. On the underside of the frame there are two sets of numbers as follows: 6515759 and 71002. I paid $45 for this bike in good but garage dusty condition. Rear tire is flat. Can anyone tell me what I have? Something tells me I did OK. If you need a pic I'll do my best to post one.
