Have just invested in a Brompton. Looking for information/ideas on modifying Messenger bags to fit Brompton front carrier frame. I've seen something a while ago but not able to rember where. Any one help please.
You should already have bought a bag support frame.. from Brompton.
For the snap together connection with the frame block , you know..
I have a messenger bag that came with a waist belt , and the shoulder strap.
wrapping that waist belt around the tubes of the bag support frame ,
and clipping the buckle shut is all I did to combine mine..
that and a stiffener of coroplast from the last years political lawn signs.
stuffed in the bag.
But really you can use their Touring Bag as a messenger or shoulder bag,
off the bike. its bigger..
with most of their bags there is a frame pocket on the back,
opening just big enough for the handle on top.
velcro straps close the bottom to keep the frame in side the pocket.
