Sram makes a dynamo hub that is specially designed to light up a low speeds:
http://www.sram.com/sram/urban/products/d7-dynamo
IIRC it tested as the slowest hub with lights off, but as the fastest with
lights on.
It is quite reasonably priced, too at $95:
The company that purchased Sturmey Archer (many years ago) is Sunrace.
In the beginning the quality from Sunrace was much superior to what had
been coming out of Sturmey at that point. Sadly, the quality level has been
decreasing for years and the people I know who sell SA hubs are now so fed
up
Anne,
Not saying it doesn't work. Just saying I personally can see a flicker in
the light at those speeds. Just thinking about Patrick and wondering if
that would cause balance issues. Also it is possible (probable?) the newer
lights have a better capacitor and don't flicker as much. That's
Eric and Anne.
What dynamo hubs are you using with which specific lights (a few Cyo models
now)? Might help to have that information.

Flashing or unsteady light at low speeds would be a problem that would end
my ride, that is true. Excellent point to consider, considering most rides
start out with climbs from my house.

I'm using a SON dynamo, and and older light. I don't remember which light
it is, but it's five or six years old.
Trying to figure out what light to install on my new bike. It has to be
something that clamps on the bars.

If flashing lights are a problem. I would skip a dyno for lights. Long, slow
climbs will cause the light to pulse at low speed . Mayberry get a dyno hub and
use it to charger a set of back up batteries?

SON hub on two bikes. Shimano 71 series on the other. All three lights
are Lumotec IQ Cyo models. One with the senso function, the other two with
just on and off.

I owned both an original SA Dynohub (no brake) and a rear Dynohub-cum-AW. I
could have installed both on one bike for an additional 20 lb and a total
of 6, or at least 4.8, volts. Really, I wish they had been less heavy,
since they seemed very well made and they certainly were shiny.

Thanks, Scott!
Great to hear, Shoji! I'll take all the no brainers I can get! Grin.
Thanks. Though the Great Divide is mostly dirt roads not single track,
though it certainly has some jouncy section that I've ridden.

I know what I'm about to write is sacrilege but Deacon it seems that the

many choices these days and they can all be Riv'd out. I think your Hung

Custom Riv fat bike??? Could it be done?!?

Thanks, Hugh. Not sacrilege to me at all. I did seriously consider a 29er+
or fatbike, but the reality is that I was so greatly under biking with my
50mm Dureme tires and set up that with the knobbied Smart Sams I've got all
the bike I need. When it comes to the drum brake question, I'm not
I asked the question about a 29er+ and the answer wasn't no. The answer was
more like If you reach the point of being serious about this, we'll talk.
I wasn't talking with Grant though.

One thing to think about with dynamo hubs. At really slow speeds climbing,
the light can start to flicker. I have it happen on my bikes around 5 to 6
mph. Not sure how much the latest lights do this, but it happens with the
Cyo on three different bikes.
As to a 29er + I'd wait. Right now, I

My dynamo works at speeds a lot lower than 5-6 mph.
