Excellent advices. Out of the box, any internet bike needs every nut and bolt tightened. The first thing is to determine whether the wheels are trued, that's a LBS task. Wheel truing makes a world of difference. Do what you can do for build, adjust, ride & readjust. Things like seat height, caliper brake adjustments handle bar and brake lever tightening. The tuning that requires special tools. the LBS will do for a reasonable labor charge. Internet bikes were put together tight enough to keep it from rattling around or losing a part here and there should the box get damaged in transit and something fall out of it like a bag of nuts and bolts.
