Impecacbly smooth, quick shifts, on the spot shifting... I was quite taken by it. However, the lady serving me warned me off buying anything with a Nexus gear on it, as apparently, an Avanti Discovery 8 sold from Spearmans has managed to obliterate two of these little contraptions... She also cautioned me that the Nexus would leave much to be desired on hills, for lack of sutable ratios, and pointed me to the slightly more expensive CRX 2.
As much as I take that advice on, I'm still marveling at that hub gear(yes, I must be an old man, a hub gear for pitty's sake ), and quite interested in the CRX city.
Has anyone here had much to do with thr Nexus, or indeed any Hub gears of recent times?

I have heard a bit about the NuVinci. Interesting idea, but so far it's rather heavy and doesn't have a very wide range so best for flat places. I'm sure they'll improve on both aspects in later versions though, so definitely something to watch out for.

The gear ratios are not a problem, durability has not been a problem either. I have done almost no maintenance on mine and it's done probably 1500 kms. If you are not happy with gear ratios, you can change the rear cog to a larger one for lower overall gears.
However, it results in having a heavy rear and less efficient gears, though the 8 is better than the 7 in that respect. You won't keep up with road bikes - but you won't on a CRX 2 either.
They're REALLY great if you're getting into cycling and don't want to hassle with the normal running gear issues.

What I can tell you about the bike is that it's fantastic. The Avanti Discovery 8 you must remember is a completely different bike (comfort) and is cheaper to boot. It also has the "standard" hub whereas the Giant has the premium (supposedly lighter and more efficient (and stronger?))
As has been mentioned you can change the rear sprocket and/or front chainring to change the gear ratios (something I plan to do as I'm finding it slightly too high for my hilly commute.) Sheldon Brown's gear calculator is invaluable for working out ratios. Sheldon Brown dot com/gears/internal.html
Obviously this is definitely not a bike to go thrashing around off road but as a city commuter it's pretty darn good. If you have any more questions feel free to ask!
