1913 Velo Torpille
The skin of the velo torpille made the bike about 6.5 kilometers per hour faster. But at the same time this bicycle was very unstable in cross winds.
The press release can also be from 1914. Because in 1913 Marcel Berthel drove - I thought - no speeds above 60 miles per hour.
This Dutch newspaper photo was ever sent to me. But unfortunately I do not remember by whom.
