Completely happy with it as it is (H6L). I bought off the shelf (rather than to order) and only things I've bought since that I would have added to a custom build are the rechargeable lights (cateye - front in place of front reflector and rear under the seat) and also the toolkit. The bike does have the front bag mount which I'm not bothered about but useful to have in case I want to use it in the future.

If I bought a second I'd probably pick up a 3speed in white although white doesn't seem to be an option on the brompton website, but only to be different from the other one and to use for short journeys
