Shutter Precision PD-8X
I've been an Alfine Dynohub user for a while now, and that thing is awesome. So awesome that I haven't had any inclination to try a newcomer to the scene.
However, I kind of want to put a dynohub on my Pugsley, which sees a lot of winter "utility" duty, and only the SP has the ability to fit a 135mm spaced fork. So, two questions about this hub:
First: How does it measure up to the really outstanding Alfine?
Second: I'm not, how shall we say...fast...on my Pugsley. That, coupled with the large tire circumference, means a lower rate of hub rotation. Might this be too slow to get a proper beam? I'm thinking it might be, but I don't want to spend the money to test it myself.

Schmidt also has a Wide Hub the SON 28 135 see Schmidt Dynamo Hubs..
" The SON 28 135 has a 135mm axle and the ISO disc mount is offered with two different disc spacings, for different forks.
RS 10mm is for forks designed for the rear disc spacing. FS 9mm is for forks using the traditional front disc spacing."
I have 3 Schmidt hubs but they are not ones for 'fat' bikes..

this takes an axle adapter, right?
I have the schmidt fatbike hub. Have to admit I have never finished final tensioning of the wheel. The reason I bought the SON was that SP pulled their fatbike hub for cold weather problems, but I see they are selling it again.

I believe they have a 3rd thru axle version, but there were pugsley's that used a rear hub on the front., that would be the 10..
before they got a company to make a wide front [hence 9mm axle] front hubs
as you see, below, they are standard QR type, using rear length skewers..

I have not tried the Alfine hub but I have both a SON and an SP on my bikes. Both work quite well. They keep a fairly steady beam down to about 5 mph, when they start to flicker.
For what it is worth, I also use helmet-mounted lights (Light and Motion Vis 360) and battery lights front and rear. I do that more to be sure I am seen, but I do have ample lights at night.

I use a pd-8x on my MTB, and sometimes I have to augment it with a battery light. I'm really slow on a mtb. Also, most dyno lights don't have quite a wide enough beam to work well on twisty singletrack. But I think most mtb-ers use a helmet light because no fixed headlight works that well on twisty singletrack.
My lbs got a SON hub for someone's pugsley, and ordered the wrong one, so they had to get a second one.
My SON is 150mm, so I guess you can't adapt that model to a pugsley without going to a TA fork.

The SP on a Pugsley is a 100mm with a 135mm adapter sold by a third party.

I was thinking about doing that before I got the bluto for my Mukluk. I was confused about the disc spacing, so I didn't do it. Then they recalled the fork and I had to go with a 150mm TA
