generator hub

I seem to have inherited a wheel with a shimano generator hub in it. Now to decide if to put it on my bike (bolt on vs qr) and what kind of light to attach to it.

God yes.
The B&M Lumotec-N Fly Plus W/Standlight is a fantastic light.

Can you solder?

Build something on this page. Anywhere from 100 lumens to 1000 lumens depending on the LEDs you use.

Put it on and enjoy!

Any of the LED Busch & Müller lights will make you happy, but I recommend the Lumotec IQ Fly.

If you want light down the road, the Scmidt E-6 (halogen) are good and there are likely plenty used for sale, as many long-distance riders trade them in on the new generation of LEDs, such as the incredible Schmidt Edelux, with same optics as IQ Fly ($200+) and Supernova E-3.

Another year, another improved light from B&M with the latest LED.

2008 was the year of the IQ Fly
2009 is the year of the IQ Cyo (50% brighter than IQ Fly, or 2x the coverage area, depending on model)

Heck yeah you want that on your bike.
Use a bolt on axle; Pitlock if you can afford it.
For a light, I suggest the asymmetrical Supernova E3 if you want something super bright with a nice shaped beam.
For something a little brighter, the regular beam E3 is great. (I've got one, and it's awesome.)
If you just want the "HOLY BALLS WHAT IS THAT!?" light, Supernova makes an E3-triple. It looks like something you'd steal off a pole from Safeco Field. The sheer mass of photons emitted by this light is enough to blow people's retinas out the back of their skull.
The Schmidt Edelux is an excellent light; better than the asymmetric E3 IMO... but good luck in getting your hands on one. Those things have been on permanent backorder since they hit the market.

The IQ Cyo has the same reflector as the Edelux and is supposed to be just as bright, at half the price.

I cannot recommend this light enough. To me it is the holy grail for a general purpose/commuting light. I have one and 2 more on the way...now if they would just offer it in a retro version...

IMO NOT going to get any where that number of lumens actual with a generator that puts out 6v at .4 to .5 Amps which is what the typical hub generator is rated for. Every hub generator I know of is rated for 2.4 to 3 watts continuous duty except for a very expensive German one I have seen listed as good for 6 watts as I recall.

You should have gone to the link before posting. A single MC-E with it's 4 dies connected in series will produce 400 lumen with a standard 6 volt 3 watt dynamo. 6 LED's in series is about the limit, then add Martins boost circuit for higher output.

The highest end dynamo in that thread is the Shimano DH-3N80, most in that thread is using DH-3D71. It is possible to generate 1000 lumens using dynamo because some people out there already have.

Can you run dual Cyo's off a 3N80 hub? I'd love to put a set of spotlights like that on my utility hauler I'm building up. One of those mounted on either side of a CETMA 7-rail would light things up like car headlights.

I'm currently using a B&M Lumotec light, but not with the LED stand light. Sounds like a good idea and a possible replacement for mine. Currently use a Cateye 3LED flashing light in addition to the Lumotec (which is really for seeing the street surface).

Thanks for posting the photo of the light.

Well that's definitely appealing. Are those selling in NA yet?

ps-> I wonder what the difference is. The edelux propaganda refers to heat sink stuff, wonder if the cyo gets hotter.

It's interesting that what appealed to me, conceptually, about dyno-halo-systems (using reflectors and lenses to get the most out of limited wattage) is less appealing to me for an LED system (less interested in a precisely shaped beam, would like to see both in front of my wheel and out to some mid-distance, but also have some peripheral vision so I can see if a deer is going to leap out at me).

The symmetrical Supernova E3 would be the best dyno/LED light if you want peripheral spill. It's what I'm using right now, and there's no clipping/shaping to the beam. It's like any HID or LED battery system on the market. Very bright, and good peripheral lighting. I suggest a low mount position to keep from blinding oncoming traffic, though.

oh yeah this hypothetical light is ticketed for the fork crown. My current minewt is further down yet, just above the low-rider rack on the fork. Not sure that does much for me in terms of 'being seen'.

I don't know about you, but wheel shadows bug the heck out of me so I usually steer away from fork and crown mounted lighting. With a little bit of drilling and grinding, I've made multiple light mounts for my front rack so that the light is far enough out that I don't get any wheel shadows.

I will have to play with that. Meantime a symmetrical shadow from the fork crown would beat the pants off the asymmetrical shadow I have right now (or alternatively I could put another minewt on the other fork arm...)

Other than that.... I'm using a B&M Lumotec Halogen front light and B&M Red LED/Reflector light powered off the Shimano front dyno-hub. It's one year old now and only had to change a bulb once. Reliable quality product. (p.s. always carry a spare bulb)

-3Bikes
I have the halogen lights and usually get 1-3 years out of a bulb depending on usage. That is why I went with the IQ LED version this time around. It was a bit more than some of the halogen versions but I think will be worth it in the long run.

I think the fork-mount on the Fly is better than in the illustration above, it is very strong and robust. I have had pressed-steel mounts fail due to fatigue. The steel rod mounting of the Fly will be the last thing on your bike to snap.

The IQ Cyo appears to be available from www.peterwhitecycles.com

It also has heatsinking like the Edeluxe.

For those that want the ultimate in off-the-shelf Dynamo brightness, it makes more sense to get the Supernova E3-Triple than to try to run a pair of IQ Cyo's.

The IQ Fly is a very good light overall, but it tends to get pushed (aimed) upward easily because the light housing extends so far above the bolt that connects it to the mount. I had to mount the light on my handlebar using a recycled shifter mount because my shifter cables interfered with it when it was mounted on the front brake mount. Having the light on the bars has another advantage, drivers see it more easily in traffic. In the photo you'll notice an out-of-focus zippy tie that keeps a nearby cable from vibrating against the light housing (just in case you wondered what it is.) I'm enjoying this light!
