Hub dynamo

Discussion in 'Technical Chat' started by Brendan Halpin, Sep 10, 2011.

  1. What's the collective wisdom on the best value hub dynamo these days?

    I'm thinking of installing a decent lighting system on my wife's bike.
    It won't get a great deal of use so value is more a priority than
    excellence.

    Recommendations for good value front and rear lights would also be
    helpful.

    Regards,

    Brendan

    I had a Shimano 3N70 for a long time, worked fine. Got 4,000 miles on
    an Alfine DH-S500 with no problems. In short, I reckon any of the mid
    range Shimano units will be fine for your needs. Even a cheap one at 30
    squids.

    The Shimano seems fine. Roos has been running one for a few years
    with no obvious gotchas. Most of our units are SONs 'cause we have
    awkward bikes (triplet needs 48 spoke wheels, Brom and the 'bents
    have small wheels, same will be true of the TSR when I get the
    enough spare cash to do that), but the degree to which they're
    better is mainly academic if you've 26" or 700c wheels (i.e., you
    ride along and apart from the lights coming on you don't notice much).

    We've a selection of BuMs, young and old. I see no point in
    getting a non-LED these days unless someone makes a gift of one.
    We've an IQ Fly on the triplet and I'm most impressed with that.
    The Cyo is a bit brighter but also more expensive and I've no
    issues at all with the Fly.

    At the back, depends what you're mounting on. The D-Toplight Plus
    if you've a rack, the Seculite if it's on a mudguard or a
    brake-boss widget.

    I'd get standlights. You don't /need/ them, but I feel better with
    them there and the extra cost brings quite a bit of reassurance
    over a working life of many years.

    Nexus if the bike is less than Rolls-Royce quality, otherwise SON. The
    Nexus has more rolling resistance but is a third of the price.

    Yup, for the OP's suggested occasional use, the bottom end model (3N30
    ?) would seem to be good enough at around £30

    Indeed, the only reason to get an halogen light would be trying to keep
    the cost down to a real minimum.

    If the requirement's is more about being seen as opposed to seeing on
    unlit road the Lumotec Lyt is really good enough if you want to keep the
    budget down as it's a fair bit cheaper than the fly

    I changed from an IQ-Fly to a CYO and I can definitely report is is
    brighter, and imho, definitely not worth the extra money. Another nice
    touch is the FLY's click-up/down feature. Small point, but sometimes
    bloody handy.

    Seconded, for a me it's a *must* for the rear, and bloody handy for
    finding keys etc on the front.

    Absolutely. I wouldn't even consider going back to stop/go. Lights that
    stay on when you stop, and hub dynamos that don't slip in the rain: the
    two main downsides to dynamo lighting avoided.

  9. German online shops are much cheaper than the UK for dyno stuff.

    I have a Shimano 3n30 with a rigida rim from laufrad.net (45 euros).
    It's not the most efficient model but is fine.

    I also have an IQ cyo front light (possibly overkill for what you want)
    from bike24.de (55 euros), and a seculite plus (18 euros).

    Agree that Shimano 3N30 is good.
    Cheap front LED light -
    http://www.bike24.com/1.php?content=8;navigation=1;product=13270;page=1;menu=1000,5,66;mid=244
    Lots of good rear LED ones available.

    That bears repeating. And sometime in the past couple of years they have
    started accepting plastic -- I seem to remember having had to pay for my
    SON with a bank draft.

    Oh thanks, I thought Basta did a cheapish one, but it didn't quickly
    turn up when I looked

    I too have had perfectly good wheels fom laufrad.net. If you settle
    for the 3N20 (no quick release so marginally less nickable) you can
    get home for marginally over €30 delivered. They take plastic and sell
    various other useful bits and bobs (eg cassettes, chains...). But
    their lights are not much cop, from memory: rose bikes or bike24 for
    them.
