I have noticed that when I accelerate hard by pedaling (doesn't mater if I'm using the assist or not) I hear/feel what can best be described as a slip coming from the crankshaft area (where the pedals pass through the frame). It makes a
Chonk sound but I don't notice anything while pedaling normally. Wondering if others have this issue? I'm a big guy so I can generate a lot of torque. Just want to get this taken care of before a small issue becomes a big issue.
