I've been wanting this bike a for a little while now, but I made the mistake of finding this thread! I feel more confused than ever.

First, according to bikesdirect.com I should be at the upper end of a normal 56cm bicycle. Does this mean that 53cm of the Nano will be too small for me, despite what Bikesdirect says about Nano sizing? I know there are people on the thread that normally ride much larger bikes, and still manage to fit on a 53cm Nano, but that all seems to require buying longer seat posts and stems that need to be higher and stretched out further.

Regarding the checking of grease. I am not a bike mechanic. I know how to do basic stuff like adjust brakes and derailleurs. But I don't have the tools or the ability to take apart the headset, hubs, or bottom bracket to check for grease. Should this be an automatic no buy?

There is also a common complaint regarding the components used being the cheapest of the cheap and junk. Is this criticism about the weight of the component, the durability, smoothness, all of the above? I'm not a huge upgrader, so I'm ok with the components as long as they don't break. One thing I noticed is that everyone hates the stem on the nano. I kind of think it perfectly matches the Nano's overall aesthetic with its thin neck and oversized head.

I do want to change out the drop handlebar with an upright and swept back handlebar. Which leads me to my next question, can the brake levers be replaced with standard flat bar style brake levers? I thought I read something about pull length or something like that that might not make it compatible.

Thanks everyone!
