Yup. I have had cheaptacular bikes from the past several decades, and the OEM pedals went steadily from strong and sturdy to meh to disposable junk. But yes, you;d probably still get sturdier peds on a $100 Walmart bike (they would last maybe a few years but that'd also be the life of the bike - Walmart doesn't expect you to repair those gaspipe beasts any more than they expect you to upgrade to Looks
)
