关于重量，Brompton的小册子有一页专门解释了Brompton的重量：
Weighing it all up
For all the options and B-spoke possibilities, the question we are asked most ofen at
bike shows is,“How much do they weigh?”
Weight does matter; people don’t buy bikes to save on buying a barbell. But weight isn’t
everything. Ride quality, frame alignment, pedalling-efciency and reliability are all
likely to prove more important in use, yet risk being overlooked by a fxation on weight.
And the compactness and balance of the folded package is at least as important as weight
in determining the ease with which a folded bike may be carried.
We are constantly striving for new ways to reduce the weight of our bikes – our products
are, afer all, renowned for their portability. But removing weight from bikes is not a
zero-sum game, and it’s certainly not something we do at all costs. We could incorporate
many lightweight materials into our bikes, but those that don’t already feature have been
rejected for shortcomings in longevity, reliability or robustness. We simply do not build
bikes to last only a couple of years, and robustness sometimes simply weighs more.
Finally, treat brochure data with caution, as not all bikes are weighed equally... Brompton
uses true weights, meaning we weigh our bikes with pedals and wheels/tyres attached; if
mudguards are ftted, we weigh those too... We take the romantic view that you want to
know how much your bike really weighs, not how much it weighs if we removed some
inconveniently heavy parts. What’s more, where there are product (and therefore weight)
diferences between territories, our brochure quotes the heavier fgures.
P.S. Te answer to the question is: “Actual weight depends on model and confguration,
but ranges between 9kg and 12½kg, or 20–28lbs.”
