Dynohub is the one of the best product in Sturmey Archer did produce, I think.
There is no mechanical moving parts means frictionless, so you don't feel heavy to pedal like one flips onto tyre,
and noiseless, maintenance free, no tyre wear.. What a great lighting system!


First 12v model was introduced in 1937

Dynohub 6v with 4speed gear

I believe there was a 9v one but never seen it.
