Annoying Clicking Noise on 2010 BMC Promachine

I get a "click, click, click, click" noise from my bottom bracket area. The noise is not constant, it only seems to occur when I am pedaling but it does NOT happen every time I pedal. When I put my bike on the stand and pedal to try and recreate the noise there is no noise so wondering if it might be related to load conditions when I pedal. However, the noise is not present at all times and it does not seem to differentiate whether I am cruising or under pedal load via different levels of effort.

I am about to take the bike to the shop to see what might be up but was curious if the collective expertise in the forum might save me a trip so I do not have to miss out on riding while the bike is in the shop and also save some potential $$$. Thanks in advance.

Do you have a kick stand that isn't retracting fully?

noises may come from anywhere... ride it, in and out of the saddle, pedaling and coasting, all combinations. it will tell you a lot more about where to begin determining where the noise is coming from. use your imagination, while riding, to isolate the noise.

Make sure that you do not have a shoe lace or derailleur wire tapping the crank arm as it goes past. The derailleur wire can be tricky to catch since it will change as you shift gears. Swapping pedals (clean and grease the threads first) is an easy first troubleshooting step. Swapping in platform pedals will take shoes and clips out of the equation.

I had similar noises. It was a bad bearing in the bottom bracket. Another time the crankarms were not properly tightened. Another time the chain had a broken link and every time I pedaled it pulled the chain apart and as it moved over the gears the side of the chain clicked against the metal.
