Hi, I have primo hollowbite v1, gsport ratchet hub and kmc k710sl chain.

Whenever I turn the cranks backwards it feels stiff and does little jumps and not a smooth turn. I am able to ride but it feels like something is gonna break. There's like little jumps and noise.

But If I take the chain off then the cranks turn fine and smooth like normal. Seems like it only happens when the chain is on? I thought it was the cranks but I am not sure or the hub? If I let the wheel spin after pedaling then its fine but maybe its the chain thats making it weird? I also just switched from RHD to LHD

I haven't ridden my bike in about a year and finally getting it fixed so not sure what could be up. I've greased and taken apart the parts and put them back together but still feels the same. Or is that how the hub is? Any help?

Chain is either WAY too tight, binding up, or your chain line sucks. Perhaps a bent sprocket? Check the driver bearings too.
