What happened to the Brompton M-Line of bicycles?

I have a Brompton Model M6R, which (as indicated by the first letter of the model) is in the Brompton's M-Line of their bicycles. But when I checked Brompton's website (in 2023), I no longer see any listings for an "M-Line" model.

I tried googling for information about the change, but I couldn't find any articles about it.

Does Brompton still sell the M-Line models? If not, why?

    This is a good article that describes the (now-changed?) Brompton model lines from 2020. But I can't find anything that describes the new models, what was deleted, what was added, and why bromptonbikes.com.au/… Apr 20, 2023 at 13:36

The new "line" naming scheme is completely different from the old handlebar-gears-wheel naming system. An M6R is basically equivalent to a C line explore with roller rack and mid handlebars.

    Is there a general pattern that can be applied to, say, the M3L as well?

  • Is there any article or PDF memo that Brompton published to dealers to explain this transition to translate other lines as well? Like @DavidW's M3L, for example. May 10, 2023 at 20:45
