Nimbus
(early twenties)
(A bike made without tubes..........and not a lot of people know that)

after a quick 5 second look at the bike, i can conclude that whichever Einstein made this up clearly doesn't know what constitutes a 'tube' ...![]()
The no tubes bit really applys to the second generation M/Cs made after 1928 up to 1960. Unless you want to be really pendantic and point out the forks are not flat metal.
... but what is the plural of Nimbus![]()

To Nimbus, tre Nimbus, fire Nimbus, .masser af Nimbus.............. etc etc etc is the Danish translation![]()
Not pedantic, tubes can be tubular or rectangular
... more along the lines of Nimbi ...

... more along the lines of Nimbi, or may Nimbularté![]()

'It was a remarkable design, since no steel tubing was used in the frame.
Instead flat steel strips were used with the long, cylindrical petrol tank welded in place. '
