Reflector pedals on bikes a nazi conspiracy. Really.

In 1936, the SS formed a joint company with Anton Loibl, a machinist and driving instructor. The SS had heard about reflector pedals for bicycles, that Loibl and others had been developing. Assuring that Loibl got the patent himself, Himmler then used his political weight to ensure the passing of a 1939 law requiring the use of the new reflective pedals - of which the Ahnenerbe received a share of the profits, 77,740 Reichsmark in 1938.
