People who write about Bromptons seem to have one quality in common, unexpected for mechanically-oriented authors: they're decent writers. Even the Brompton owner's manual is clear and succinct, and Henshawe's combination of a history of the company and supplemental hints about managing a Brompton makes for useful and even enjoyable reading. Did you know, for example, that your partially-folded Brompton can be used as a seat while you're waiting for your train? Or that the most common mistake made in removing a rear wheel is taking out the set-screw in the chain tensioner? My only complaint is that neither book stands alone. Both assume that their readers are cult members, and know a quite a lot about Bromptons already. I bought Henshawe to get a more thorough treatment than the manual affords of procedures to repair and care for my new bike, but found that he doesn't bother to incorporate information from the manual. So, I need to have both books open when I do any work. Still, worth a Brompton owner's time.
