put clipless pedals on that bike, non folding most likely as otherwise choices are pretty rare
get 200 dlr shoes
clip in and ride ...
until there is a red light, you stop, you fall over, break your hip
no problem with any seatposts anymore ...

what a piece of bs.. to say that clips are fixed and clip ons are better because of that. Clips come in a variety .. half clips , full ones, double ones, leather straps ..and all are adjustable and allow easy in an out . thasn there are powerstraps which allow free movement , easy in and out, and all with regular shoes .
He likes clip ins as they need exact installments and positioning, where he can charge customers a small randsom ... easy as that...
