I don't know much about the bike equipment (pedals are pedals in my opinion, only difference would be how long they last, thus my replacing my ride with the kids bike's pedals about 3 times because they were plastic pedals on the Walmart shelf before I started riding for fitness.) I developed a creak in the general pedal area. It ended up being the crank and I loosened the nut, greased the threads, and retightened the nut. Creaking gone.
