Hi HC,
This is theoretically a great idea.
Occasionally after landing at smaller airports in the US I have been given a car to "run into town" totally free of charge. Just bring it back later... etc...
I have 2 Di Blasi folding mopeds (hence "Scooter" Boy) but am fed up with their lack of reliability. They also stink of fuel (even if you carry them with all the fuel drained out) and are very heavy for 1 person to lift into the aircraft so am probably going to get a couple of Bromptons instead.
These are the very best folding pushbikes in the world without question and should ease my transit from airfield to tube etc...
Hopefully Santa will oblige...
SB (soon to be Brompton Boy)
