as a novice thought it better to let them check if over,
I have seen some link when Cell and Reid / Kmart bike were not greased properly and not all bolts tighten .
I am also going to get a correctly fitting helmet and some riding shorts/shirts
( the $14 Aldi one didn't fit and look crap)
I don't know your level of mechanical aptitude.
Bicycles are a relatively simple beast compared to the automotive field.
I'd look at it as also a cheap learning tool to develop a basic level of servicing/set up ability.
There is a heap of stuff on you tube if you research, and people on here are happy to help if you fire off a question.
