Vincita is now offering two 4-wheeled bags for transporting Bromptons,
B132C
and
B132H
Recently I traveled with a Brompton in a 2-wheeled Vincita bag B132B, mixing air, train and bus, and having 2 wheels only was a major drag. I had to maneuver several pieces of luggage. The B132B bottom sagged and rubbed the ground forcing me to lift the front of B132B extra high. I felt that a rigid bottom to the bag with 4 rather than 2 wheels would be a major improvement. With this, the new Vincita bags could offer a a way forward. There is some increase in weight but still tolerable, ~1kg. However the wheels in B132C/H are in-line rather than spinner. If bottoms of these bags sag, the advantage of 4 wheels disappears as one needs to lift one side anyway. (The photo already suggests a problem.) Has anybody got an experience with either of these bags, B132C or B132H? I believe they can be used for other bikes too.
The wheels seem to be velcroed to the bags. I.e. one might think of a replacement of the in-line wheels with spinner.
