I wanted a bottle mount on my Brompton for longer trips without a bag. Problem is every cage and mounting location would interfere with the folded size. Well, I came up with this solution...Vincero Design magnetic bottle mount and bottle.



The mount has a magnet where the logo is.


The bottle is made for the mount and has a magnet pressed into the bottle.


This is the view from the side...it doesn't stick out at all.
