Is there a fast on/fast off Trunk bag for a standard Brommie rack? I hate velcro but not having much luck finding something with super fast click off. I'm handy and can rig up something but so far, no luck. Anyone using the ortlieb with the rack retention system?

Modify what you have? I would think the Ortlieb mount part's thickness
needs larger EZ wheels ,
to not drag the mount, on the ground, when folded

I saw, in my Trek dealer a rack bag with a push button and a catch ,
that integrated with their rack. Worked well ..

My Brompton, I only have an M3L, I have a Carradice SQR support,
on the seat post,
with one of their big saddle bags..

It comes off easily.. , nothing interferes with the 'kickstand' rear fold under..
