    Nexus Hub Question

    I'm soon to take possession of a cheap bike bought on ebay which utilises a seven speed nexus hub. I hope to use the machine primarily to take me through my winter commute - my existing bike with a derailer set-up having took a predictable hammering from the weather/road dirt in the last winter months.

    I was wondering however whether it was possible to mate the nexus hub with a multiple (2?) chain ring set up at the front end to give me a wider range of gears, and whether this was a sensible thing to consider, and to enquire if anyone had been down that route before and could let me know how effective it was. Alternatively if it's just a daft idea I'll drop it now.

    It may be the case that when i have a chance to test the bike on my normal commute route (24 miles round trip) the gearing is fine anyway.

    Many thanks in advance for any advice you can give me.

    The big issue is you'll still have to run a rear derailleur or something similar to take up the chain slack when you shift into the smaller chainring. Figuring out the cable routing to a front derailleur on a bike that wasn't designed for it might be more than you want to deal with too.

    "whether this was a sensible thing to consider"

    Unless you ride were there are steep undulating hills I really doubt you will get any advantage from a large number of gears. If it bothers you buy a few used chainrings on ebay and see if swapping them makes a difference (I doubt it will). If you do this you will have to buy a new chain too.
    2000 Montague CX, I do not recommend it, but still ride it.
    Strida 3, I recommend it for rides < 10mi wo steep hills.
    2006 Rowbike 720 Sport, I recommend it as an exercise bike.
    1996 Birdy, Recommend.
    Wieleder CARiBIKE (folding), decent frame.
