I just wanted to say welcome and that is a nice looking bike! I love the accent colours with the white. After you ride it a few times you will probably gain some confidence and start to relax. And before you know it you will be having a lot of fun riding! I don't know much about various locks except you should use one. My son's bike got stolen at university the one day he didn't lock it up and it was just a cheap Walmart road bike. But he still misses having it since he can't afford to replace it.
