Owners of Brompton bikes often call their bikes as [bromi] bikes. I am wondering what is written version of this word. On the internet I can find all three versions. What do you find best one if I want for instance to register domain name with this word. Thank you for answer.

    I would say that the majority of English speakers don't know what a Brompton is.

  • @HotLicks - Harsh, but probably fair. I suspect that if we limited it to people in big cities in England we might just about manage a majority.

  • Note that for a domain name it's probably better to have a slightly quirky term.

As a former Brompton rider - er, what? I called it a Brompton. But googling suggests you're not incorrect that some people abbreviate it.

From the point of view of English, in order to maintain the vowel sound of the "o", your abbreviation should have a double "m". It could end "-ie" or "y".

Doing a custom google search on www.myorangebrompton.com (as far as I know the most popular blog about bromptons) yields 47 hits for "brommie". I got 1 hit each for "bromie" and "brommy". No hits for "bromi" or "bromy".

A google search for "brommie folding bike" found plenty of hits (25,500). Not all of the pages' synopses have the word "brommie" but plenty do. A similar search for "brommy folding bike" yields 6200; "bromie folding bike" gives 3800; and "bromy folding bike" gives less than 300, but the synopses don't look like they're using "bromy" as an abbreviation for brompton.

In conclusion, I'd recommend "brommie" for both working with English's usual pronunciation guidelines and being in (relatively) common usage already.


I believe you are more interested in the most commonly searched rather than the best word. There are tools to do this - https://trends.google.com/trends/explore?geo=GB&q=brommie,bromie,bromi - it looks like bromi takes it.

  • How many of those results are for brompton bikes, and how many for other things?
