I would not worry about it, go and enjoy your bike, the RAD's are a little clunky compared to high end e-bikes, but they are pretty reliable. I have not done anything to my Mission except adjust the brakes occasionally , they stop the 45 lb. bike great. Like any bike, check all the fasteners for tightness, and cable connectors to ensure they are snapped in and tight as well. These things will give you a lot of miles.
