Sram makes a dynamo hub that is specially designed to light up a low speeds:

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
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.

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

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?

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.

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.

What dynamo hubs are you using with which specific lights (a few Cyo models
now)? Might help to have that information.

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

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 do
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.

Probably pretty sick, but theoretically you could set the bike up like a
tandem, only reversed: SA Dyno drum on the front activated by the left
lever, SA IGH with drum on the rear activated by the right lever, and then
a canti-brake on the front activated by a mountain or interupter lever.

At least with the Sturmey drum brake front hubs, tire change issues are trivial
– it’s very easy to connect and disconnect the necessary bits.
I have a Sturmey dynamo/drum combination on an old Fuji Sundance ’80s mountain
bike I built up to be a rain and snow bike (hence the drums). It’s quite
