The MOST likely cause of the tick is a pedal, crank or bottom bracket that is not properly tightened, and it's very important to get it attended to before it gets worse and causes damage. This is not the thing to learn on, as you could void any warranty by uninformed disassembly and "fiddling." Speaking of that, jumping the bike, especially if not done properly to absorb shock, can not only cause undue stress and damage but also void the warranty (which you should read).

If you want to start learning, ask the mechanic when you take it in what to do for basic maintenance and how to do a "quick check" of your bike. Then start reading sheldonbrown.com, parktool.com/blog, or if there's a bike co-op near you by all means go there for support.

If you can't manage to answer straightforward questions we cannot help you anyway, and doing so long distance is already challenging.
