The reason people don't use dynamos often is that good ones cost $300 + another hundred + for the lights, and if you're spending that much money, you're serious about wanting to ride all night without worrying about batteries dying.
If you're out for a couple of hours, batteries are grand.

- ajuc 7y agoI wanted to buy a dynamo because I was driving long-distances with smartphone navigation and listening to audiobooks, and my smartphone was dying after about 6 hours. I looked at the options and bought a $50 20000 mAh powerbank instead. Enough to charge the smartphone 4 times and the lights basically forever. Dynamo is much more likely to break than the batteries, less convenient, and more expansive. It's obsolete technology IMHO.
- hprotagonist 7y agoI've put about 7,000 commuting miles on my SON hub in all weather conditions. The previous owner put another few thousand on in maintenance conditions I don't know the particulars of. I expect I'll need to service it in another few years. In the meantime, I've gone through at least three reasonably priced battery packs; two because they crapped out, and the last because i wanted USB-C. I'll take the dynamo hub any day for my bike lighting and power needs. oh, and as an added benefit it's way less of a hit on the environment!
