I'm enrolled in next week's Pedals 2 People Wheelbuilding Class. My plan is to build a coupla low-budget dynohub wheels. I guess batteries are necessary in life but they suck and I love the concept of powering your lights with your feet.
Trouble with dynohub wheels is that it can run into the hundreds for a normal person to get one built. That's way more than most bikes are worth. While we're waiting for the whole bike industry/consumer demand deal to start driving generator hubs, it would rule to be able to take a common wheel off a common bike and put a reasonably-priced dynohub on it and tie a cheap, effective headlight to it and go.
I ordered a coupla very affordable dynohubs for the class - the one on the left is 40 bucks and the one on the right is 50. Neither one's gonna win the low-rolling-resistance award, but in the way I picture them being used, does anyone really care.
Fabulous theory, all fine and well, until I actually had to think about taking the front wheel off of the dogbike, thereby rendering it useless for the next several days. I should just say, that in the history of utility bikes, I'm not sure that one has ever been more utilized. I thought that at least we should go for a run first, so we did.
I'm breating into a paper bag. This is not easy. I can only trust that things will somehow work out.
