I know the feeling. Worst for me was when I ordered my Swift. From the time I actually placed the order until the bike was in my hands was 6 weeks. It was terrible to wait that long as I had ordered it before Christmas hoping it would arrive. It wasn't to be as it came almost a month later. I have to say it was worth the wait!
Take the time to check everything over before you ride. If you don't know what to do, take it to a bike shop for a quick tune-up/inspection. Have them check the wheels, shifter and brakes at a minimum before you go for a ride. Shipping can sometimes be rough on bikes.
