Or why can't you just carry smart panniers? I think it may be that you want cycling equipment but not to look like a cyclist. Nor do many business folk, but they they don't cycle, they use planes, trains and automobiles (taking the latter to the airport or station)
Like I say I want wheels - that's the whole point of this thread! Wheelie luggage is what anyone sensible uses nowadays. I will be carrying fairly heavy weights and walking for long distances. The wheel is the only way forward.
No, a lot of business people DO use bicycles. Particularly if they are young-ish and/or into the environment. It is a fast, efficient mode of transport that is good for the environment. The crunch problem is that it can make you look scruffy and look amateur and like you do not value appearances.
