Bromptons have many unique features but one that I don’t like is the lack of a bidon cage mount. Carrying water on a ride in this part of the world is pretty essential.
My Brompton C bag rear pockets are a workable solution for a bidon holder but I prefer a cage for my bidon. Searching the Internet has yet to identify a cage mount that I’d be happy to use & I even have doubts about the rumoured Brompton magnetic water bottle. Many times I’ve returned to the question of how to mount a cage on my Bromptons & all I resolved is that a cage needs to be behind the stem, not impede the fold & be easily removable. And then, a new thought…
(a quick shop for some O-rings, various attempts with some Aluminium strip, add some foam to protect the stem paintwork, bolt on a cage, voila!)
Ralph (see pic) & Robinson now have bidon cages! So far, so good…

Ian, if you had the time and inclination you should consider setting up an online store and selling some of the crafty little brompton solutions! I’d be a sure customer!
Thanks Dion – but no thanks. I’m just hopeful that people can translate the ideas into their own solutions (& maybe produce excellent production items?) My production quality leaves a bit to be desired (I blame my limited garage setup? haha) & of course, there’s always the “mythical” Brompton magnetic system around the corner? Also, I’m waiting to see one of the Monkii cage systems & maybe swap to that? (although I don’t need to be in any hurry)
[…] original version of a Bidon Cage was fitted onto both Bromptons, Ralph & Robinson, & have proved to be an excellent setup […]
Hi. Where can I find something like yours bottle cage holder?
Sorry Carlos, nothing really close that I know of – although the Monkii system may suit you. For more info about my setup, see “https://aussieonabrompton.com/2014/10/06/an-on-going-interim/”
