Just come back from riding my Brompton, which is still quite new to me and I'm still getting used to. I'm really surprised how smooth and comfortable the ride is, it actually beats my 20" Dahon despite that having massive tyres and thudbuster, I think. The one thing I'm not keen on, however, is the amount of flex in the handlebar stem, which strikes me as the only thing preventing this from feeling like a design with no compromises. I'd imagine the S bar largely does away with this problem so for those who are happy with the riding position offered by the S-type I reckon it's a near-perfect design. Having said all that the bike I'm riding was manufactured in 2001 so perhaps there's been some slight improvement in the stem flex issue. . . and if that's the case then I'd have to get hold of a more recent model. Of course if there were less flex in the handlebar and stem I may find the ride somewhat harsher. . .?
