In a flat city in 2000 I rode a non- folding bike no problem.
In another flat city during periodic visits from 2011 to 2014 no problem, even though not perfect fit on this Japanese 20" wheel bike
Both biking daily
Problem arose only with folding bike in hilly places. But I have gained weight gradually (174 cm, 79 kilos) and am a semi-geezer of 58. I have stopped swimming for one year. The knee problem actually first manifested during swimming. I use only frog abrupt kicking motion.
