Most experienced cyclists strive to maintain 80-90rpm. If you are not at least at 60rpm, you are pedaling too slow with too much pressure on each stroke.

yep. High rpm low force is a must. Shoes with cleats help there. Though to spin 100 RPM on flat pedals without toe clips, and toe clips cause other issues, like sore toes. Best is clipless pedals and special shoes.
