Dynohub history rabbit hole for those interested:
No, it's about a tenth of that, light included.
I explored dynohubs in the past, but LEDs and LiPo batteries have really narrowed the gap. In my garage, I've got a super long USB cable that we all use for charging our lights. I've used cheap lights from AliExpress, and they are actually quite durable.
bikepackers aren't an homogeneous population. Some are more instagrammers than bikepackers and are using expensive bikes and equipment, others bikepack on a shoestring budget with stuff from the thrift stores and you could mistake them for homeless. And finally some are actually homeless. And you get any kind of budget and requirement/vanity level inbetween these 2 extremes.
This summer while I was cycling I came accross an ukranian guy who was bikepacking accross europe with an old mtb from the 90's, using an old kids trailer to carry his gear and water supply. He was stranded in a climb in the middle of nowhere with a broken wheel, 3 or 4 spokes had given up the ghost, and the tire was flat you could see the casing instead of the tread on both wheels. We could only communicate using google translate on my phone but he told me straight nomoney. His tent, which he had setup on the side of the road to have a bit of shade could have come from a dumpster judging by its state and discoloration, that tent was 20 to 30y old. Since my daughter has a folding bike with 20" wheels and I was 20 minutes from home I convinced him to give me his wheel, filled his empty water bottle with my own, gave him some snacks and went back home to check if spokes length matched any of my daughter's bike wheel and relaced quickly his wheel using 4 spokes from my daughter's. Then I climbed back that climb with the repaired wheel, 2 tires from my daughter's bike, a veggie sandwich and 4L of water (having myself a bike that is bikepack ready made it easier) so he could eat something and set off. He paid me with what he had available: a big hug and proposed to help me with my back (I understood he was some kind of chiropractor) which I declined.
I also met a number of homeless people while on a long bike pack (C&O + GAP). They were usually pretty hard up: they lived in junky tents off the side of the trail and used their bikes to commute to work. It’s hard for me not to think that we have failed in an important way if somebody is dragging themselves to work while living out of a tent.
Seems a little performative to me, that's about the weight of all the raindrops on your jacket.
Not having to charge anything or worry about batteries running out in the dark is a real benefit.
It's all on the very opposite end of the cost spectrum than the cheap bike light in this post though
They're just generic AC motors held against the rim, as simple and cheap as it gets. Nowadays I'd add a basic voltage regulation circuitry to get a stable 5V DC out of it.
You'll spend more time futzing with one of or dealing with weather-related failures that you would have saved more time charging a pile of batteries before every ride.
I have rigged all kinds of rubber contraptions to make them work better, I have made my own dynamos from old electric motors as a kid, and yet I have never in all those decades found a way to be sure they would work when I need them, never.
I recently bought a dynamo from what should be a good brand (dunno the name off the top of my head). Cost about 45 Euro's, not cheap. Just after a couple weeks, whenever I cycle through the rain my dynamo wheel would slip and I'd be fully without light. I thought it was not properly pressing the rubber of the tire. But I found that the wheel was just cheap plastic garbage, totally worn flat already. I guess capitalism flew by, enshittifying once more what was once good.
The old-school dynamo's were undestroyable iron casings, with an iron wheel with deep grooves. Now I am looking if I can find one of those again, to last me a lifetime.
