Hi,
I sell my Brompton Metro bag, it is full waterproof and size Large.
You can put it on any brompton (non electric) front block.
It is in very good condition, no scratches, no problems.
You have a shiulder strap when you're not riding, very nice and convenient 👍🏼
I sell it hand to hand to brompton lovers (on Amsterdam)
See you soon 👍🏼
