Bill and Joe,
Yes, of course. I didn’t mean to demean dynohubs and certainly not the people who use them. My point is that just a few years ago dynohubs were the clear winner for anyone doing longer rides. But batteries are really getting stronger, cheaper, and lighter. Like 10,000mAh with two USB ports for only $37 and weighing 204 grams. That’s hard for a dyno to beat now and batteries are getting better all the time. In contrast, unless there is some breakthrough, dynohub technology is pretty much as good as it will ever be.
