Annoying clicking sound from the bottom bracket I just purchased a Fuji ACR 2.0 road bike from a guy who bought it three months back but didn't ride it at all. I brought it home and found that it is making a clicking sound when I pedal. The sound is coming from the bottom bracket. Please check the video for more details:


                
            

Should I worry much about it? I'm from Bangladesh and there isn't any specialized shop where I can take it to be inspected. I have to do the fix myself. So before I jump in to open up the bottom bracket, I wanted to get advice whether I should ignore it and ride it for few days hoping that noise will go away...

Is it happening only when you pedal backwards or forwards too?

I note you have a small spoke guard on the back wheel.  Take a close look at that.  It might be cracked and when you back pedal the freewheel teeth might be catching on it.  It seems way to loud and plastic like to be a crank issue but then again I'm not there.  All my crank issues have had a much more solid clunk sound and were not nearly as loud.
