Who's dime is it on?

The Brompton is a great bike for the city - folds quickly, tightly and very small; rolls nicely if you get the rack; and the front luggage block is an ideal place for cargo - and you don't even need to remove it for folding, or wheeling around while folded.

However, as a former NYC bicyclist, I'd be concerned with the following, particularly in your profession: Bromptons are quite expensive; small wheels cannot absorb, or roll over, bumps and potholes as well as larger ones; the luggage block is held by 2 bolts and with no shock absorption between what could be a heavy load and stiff small wheels; I recall riding up and down curbs all the time (bunny hops, jumps, roll up/down unweighting, etc.); and you will be folding/unfolding dozens of times a day. All perfectly do-able, but keep in mind what all those extra joints and moving parts mean in terms of frame strength, durability, and wear and tear, in your demanding profession.

On someone else's dime, I love to see how a Brompton would hold up to this torture test, but on my dime, stuff this expensive tends to be babied more.
