No, not likely worn out. If it's a pedal bearing, the click can come and go, as often it's dirt that will work it's way out with a good washing and some riding. It is a serviceable item though and noise often means maintenance is required (clean & lube), with any bearing noise. Bearings on bikes will tell you "click" when they want attention. Given your bike is new, it may be covered under warranty.awesome! mine's making the same clicking. Can't be worn out at less than 100 miles, whats the deal here? ST1 here.
I had the same problem and found the same solution.When my bike arrived, the front derailleur cable extended past the clamping screw so that it touched the right crank arm every time it passed through the top of its rotation.
In my case, I wrapped the cable around the clamping screw so that it would not touch the crank arm.
