Yes, well over ten. My 1953 GH-6 Dynohub still works fine (if you prefer
a dull yellow Lucas-like glow).

The Sanyo Dynohubs on staff from early 1980s are quite bright. Newish
models are both bright and about 25% cheaper but that's not news any longer.

Dear Andrew,

Humber advertised its "amazing patent Dynohub Lighting unit" with the
claim that it was "frictionless" in 1938:

Sheldon wrote about the Sturmey Archer Dynohub and included a 1952 ad:

There, the claim was modified to "mechanically frictionless."

S-A fans can read the short 50th anniversary Sturmey-Archer history
pamphlet at Sheldon's site by going here and clicking on next:

Caution: giant butterfly axle nuts and piratical eye-patches.

These amazing Sturmey-Archer mileage claims raised my eyebrows:

"In 1939 Tommy Godwin, using a Sturmey~Archer hub, broke the year's
mileage record with the amazing total of 75,065 miles. Not content
with this he went on to cover 100,000 miles in 499 days."

That's 205.65 miles _every_ day for a year in 1939, and 200.40 miles
per day in 499 days.

Some details about Godwin's amazing mileage appear he

But my eyebrows disappear skyward again when I read that he maintained
a "strict vegetarian diet" throughout his feat and then "spent weeks
learning how to walk again" after he stopped.

Still, 200 miles a day for all but 8 days of a year is possible, so my
eyebrows have returned to a normal level:

Freddie Hoffman never claimed to need to learn to walk again and the
noticeable spare tire mentioned in the article suggests a carnivorous
diet.
