I recently purchased a Novara Flyby from REI. From what I understand, it is a rebadged version of a Tern bike. It seems most similar in specs to Tern Link C7i and Dahon Vitesse D7HG. Does anyone here have any experience in maintaining a bike of this type? How often do you clean and lube the chain? Have you had to adjust the chain regularly? And how often do you replace it? On the Flyby, the chain is mostly covered in black sheathing, which limits its contact with the elements but also makes it harder to clean it.
Also, I don't have any previous experience with internal hubs. It seems that they require periodic cleaning and rebuilding. Has anyone done this?
Finally, what kind of care do the folding hinges require? Any other maintenance issues to be aware of? Thanks.
For what it's worth, I have the Tern P7i with the Nexus 7 hub; it's almost 3 years old with about 4400 miles on it. It has been ridden in all weather (rain, sun, snow, ice, etc.). The only maintenance I had to do on the hub so far is to just remove the outermost locking pieces to clean under the adjustment window, after a really bad snow/salt/rain season.
I have heard of people with 'Alfine' hubs who need to drain, clean, and refill the oil. I have also heard of people doing a full refurb and regrease on the Nexus hub but I haven't done it yet.
