It depends. Which model is she buying ? For example I have a Kilo WT with sealed cartridge bearing hubs that require no maintenance or adjustment. I also have a Moto Mesenger with loose bearing hubs that needed adjustment and will need periodic cleaning and repacking with new grease. Also, the wheels on the Moto needed a lot more truing and tensioning than the Kilo. The cranks on the Kilo were pretty tight and only needed to be retightened a few times but the Moto needed about a dozen retightenings. The chainring bolts on the Kilo were tight from the git go, but those on the Moto were all loose. Then, there may be bad or ill fitting parts or even missing parts. The seat binder bolt on my Kilo was stripped and the stem and bar on my Moto were the wrong size. So, it needs to be thorougly checked, and remember to not force anything.
