Sturmey-Archer AG Dynothree hub

I recently acquired one of these hubs, and inspired by a similar vid on YouTube I created a test-bed to try it out with a headlight. I already have a regular S-A front wheel Dynohub on my Raleigh Superbe, so I'll need to build another bike for this one.

great until you have to stop then no one can see you!

...don't use modern rims? I had a set of generic (perhaps dunlop) 26 x 1 3/8ths rims. Even with the spokes rather slack, they held up well going over curbs, potholes etc etc. I used to ride the bike they were on at the local BMX track and show the kids how jumps should be done. Sure, they are heavy and braking could be better, but for the conditions they were expected to be in, they were quite possibly the most versatile rim size.

For riding to or from work on relatively flat terrain during the 50's, 60's and 70's you didn't really need much in the way of advanced technology. These weren't as such a revolution in technological evolution, they were just a way of convenience and cost savings.

Ya screw batteries and led too. I can just hear em whine. Oh it makes it harder to pedal.

You can now get LED lights with slow capacitor discharge which work with dynamo hubs and are really the best of both worlds.

thats main and dip beam

often those old hubs are 40 hole.

bit more difficult to get modern rims in that drilling

cool just saying but you should try a wind turbine out of the dynohub!

You're right, who needs batteries? :) That headlight was an awesome idea back in it's days, of course it can't compare to today's high power LED lights.
