Sanyo Sidewall Dynamo LED Unit
My wife brought me a present from Japan, admittedly one I asked for:
The Japanese on the packaging is about how this unit is wonderfully light, bright, quiet, and has low rolling resistance.
My inaccurate postal scale puts it at 8-9 oz. It has 4 LED's - three are for the main light, the fourth is a yellow blinky standlight visible from the side as well:
Just rolling it back and forth with my hand it seems to live up to the hype on the packaging - it is very smooth, quiet, low resistance and at that speed clearly lights up a darkened room. Ten seconds of rolling or so gets the blinky standlight going for at least a minute or two.
The big question now is how to mount this on a bike with cantis and Nitto M12 mini-rack.
The dynamo unit has to contact the front wheel ahead of the rack strut, which means the whole unit has to go in front of the strut. The light portion can be adjusted up and down.
I'm a little concerned about having something cantilevered way out front like that, esp. since I routinely ride on unpaved roads/paths.
I foresee an afternoon of hacking around with an old union bottle dynamo mount designed for rear chainstay position that I have around. The light unit is easily separable from the dynamo unit, so I could mount the light in the strut mount and then have a little more latitude in mounting the dynamo.

Mount the dynamo behind the fork blade, the lamp between the fender and rack...out front.

Here you go. I have no idea what the shipping would be to the U.S. In principle, the Rakuten vendors who allow their stuff on the english site are supposed to at least be willing to ship internationally.

Otherwise, though, that would be a clean solution.

Could you fabricate a flat stainless steel strip that mounts to the left canti stud, then extends down and twists 90 degrees? Much like many modern rear rack stays. That would approximate the position where a brazed on sidewall dyno mount would be.

Oh perfect! this is from the website selling this:
https://global.rakuten.com/en/store/k...2_016_nh-v68a/
If you are bike lights that light up the tires rub,
"What I do have a bright white and auto light."
Have you ever, do you? ?
Blocks beyond the common sense of a dynamo!
Wright came out great! !
Provide white glare!
Low-load dynamometer
Approximately 30% lighter than conventional rotary torque ●, sticky and reduces the weight of the pedal paddle
-------
I've can totally relate to all of this. This sounds great and it's exactly what I've been looking for. I'm ordering one now.

Anyway, I really would like one of these but I can't seem to navigate the checkout process.

FWIW, my wife has been doing the same to me for years whenever we need to call the bank, gas company, etc, in the U.S. and straighten something out.

Sorry, can't help you there. Every now and then when I find something on rakuten, usually on the Japanese domestic site, I just give the link to my (Japanese in Japan) wife and try to sweet talk her into buying it. So I don't really know what happens after that step. I do know it is one of the biggest commerce aggregating sites in all of Japan.

This isn't speculation, I know this for a fact having worked w/some others trying to import some similar stuff a few years back. A lot of these Japanese domestic market cycling products, they won't let their online retailers sell/ship to the U.S. either for the same reason.

Hmmm, I understand your concern. Probability of it happening is low with your build quality level. But accidents can happen as you so well know. The chainstay/BB mount is the safest bet. Are you thinking of it rolling on the tread or tire wall?
Btw, it is a very cool light.
It sounds like a call to Dawes-Man for a group buy!

That appears to be designed for mounting on the right side. I did not see a bracket for mounting it onto the front fork in the package that you showed. Block generators have been around for ages (but not for LED's). The preferred mounting was a braze-on for the front fork like this

(concerning the standlight feature) "While waiting for the signal "We are here to bike." Appeal around and made safe."
"30% lighter than conventional rotary torque" "sticky and reduces the weight of the pedal paddle!"
I spent a summer years ago in Japan with my brother (who still lives in Kawasaki) and remember seeing an advertisement for a bowling alley in the subway station that said "Let's play bowling!". My favorite was a sign on a low stairway ceiling in Nagoya Castle that said for all the English speaking tourists "WATCH OUT YOUR HEAD!"
Of course I brought home some shirts with random Japanese characters on them because they looked so cool. They probably said something like "I'm an idiot who can't even read this shirt I bought" (except I think the Japanese are way to proper to put that on a shirt and sell it to unsuspecting tourists).

Well, I think I'm going to think about the mounting for a while. Couple options in play. The block unit separates nicely, so I do have the option of mounting the bottle where convenient and the light where effective. I probably will go with the bottle mounted behind the fork on the left side w/a spanninga fork mount and the light somehow hung from the the rack light mount on the right side.
That is, unless something better presents itselff while I"m futzing around in the garage.

This one is attached to a VO front rack with an M5 bolt, but it should work equally well on that Nitto M12 of yours which has the strut-mounted M6 threaded eyelet. It's also more stable than any of the brackets sold by Rivendell or VO. Several hundred miles of dirt road and trail riding, and it hasn't flinched. The flush-mounted jack is for charging a portable electronic device.
