The luggage block on a Brompton, like so much on the bicycle, is sheer genius. It places the weight of front luggage on the frame, which means that there’s no destabilization when turning, even when carrying substantial weight.
But it can be a little inconvenient to reach under a bag to pull the release lever. Fortunately, the lever has a channel running through it — it’s that little circle on the lever, below the block, modelled above by Argyll.
I added a cord loop to the release on Basil’s luggage block. It loops around his stem, stays completely out of the way, and makes it much easier for me to release a bag.
The cord is run through from opposite sides, and knotted on each side. In a belt-and-suspenders move, I also stitched the loose ends to the loop.
Viola! Pull the loop and release the bag; no fumbling under the luggage required. This might not be a big deal for many people, but my runty little arms really appreciate the more convenient reach. It’s speedier, too.
I saw this nifty fix when I followed a link from a bikeforums.net discussion of Brompton luggage. Poster trrubicon06 made a far more elegant one (using actual hardware; his Brompton may be an older one without the channel in the release lever).
