I picked up an exercise bike for the low price of free by the side of the road, and it works! However, even when I place the seat the highest it can go I can't fully straighten my legs 😔 I'm not even that tall.
It's possible I was misinformed when I was told that the proper height for a bike seat was so your leg is straight when the pedal is at its lowest. Because I see so many people waiting at street crossings with their butt on the seat and a foot on the ground! Which I can't do if my leg is already extended when I'm pedaling. Otoh I get more leg cramps if I never straighten my legs, so I think I'm going to keep doing it the way I've been doing it.
