I’m looking at picking up a $100 Motobecane Jubilee from the mid-80s as a commuter bike (3x/wk, 18 mi each way). I really only have experience with newer bikes with shimano and 700c wheels and such. This bike has suntour components. Is it going to be difficult to get parts/keep it maintained? I can’t find any info on what the frames are even made of. Is this a decent ride or should I keep looking? Here it is:
