For a quick, week-end trip back to the Bay Area I wanted to travel light — no checked bags — just my folding bicycle and a backpack with the goal of leaving the airport via bike.
Last time I flew with the Brompton, I checked it as baggage. However, I had to deal with a giant, hard-shell suitcase once arriving at my destination.
So this time I tried a different approach: I brought the bike through security, put it on the x-ray machine’s conveyor belt, and gate checked it at the last minute like you would a child’s stroller.
The plan, which included carrying my back-pack on-board as a carry-on, worked perfectly.
The Brompton doubles as a luggage roller (albeit a tippy one) as you can see in the picture, made outside the Embarcadaro BART station early on a Saturday morning after my arrival from the airport.
At this point, I was able to easily ride to the Marina district where I was staying as well as make my way multi-modally (can I use this in adjective form?) to other appointments in both Marin and Berkeley.
End note: There is a solution to the Brompton suitcase dilemma which requires packing a portable, folding trailer. Here’s a chap elegantly demonstrating this option in a video in which he unpacks, assembles, and rides out of the Copenhagen airport on a Brompton with his luggage in tow.
