Bicycle Mechanics - Mysterious clicking sound near Crank/Bottom Bracket/Rear Wheel area

I have a Scott Speedster S5 2009 series and I have started to use it more regularly. Whenever I am pedaling down from the top most stroke be it on the left or right feet, a soft but sharp pitch clicking sound appeared. It sounds like it is coming from the Crank/Bottom Bracket/Rear Wheel area. I have tried to but it on a bike stand and use my hand to pedal really hard but that sound doesn't surface. This means that it only appears when I am sitting on the bike. Mysteriously, the sound only comes when I travel above 15km/h. I have sent to a bike shop but they couldn't really find the problem. I have maintained the bike after every ride and took good care of it. Anyone have encountered such issues before? Please advise as I am really worried. Thanks

Read the stickies, there are lots and lots of possible reason, from crank to saddle, you need to eliminate each one.
