Take the chain off of the cranks and spin them. It could be the bottom bracket, but I’ve felt old chains be as problematic. What is the condition of the chain? Maybe it’s not engaging the freewheel and crank well?

About two years ago I went through it and replaced bearings and grease. It felt new, with a bit of worn feel while pedaling. After two years of commuting, I can feel what I can only describe as a gravel or crunch feeling through the pedals. Is that the bottom bracket? There is no play in the crank arms. The cassette is worn, but I don't see how that would cause what I feel while pedaling. It's like pebbles are inside the BB. It's likely due for an upgrade or at least a new bottom bracket. Thoughts? Sorry for the bad work photo.
