Brompton owners

How tall is your missus? even the flat bar one isn't that low as it look as the stem on the S type is slightly longer than the standard M type.

This is moot since you want a front basket and the Brompton claim to not be able to fit it on such frame (S type).

Of which remind me to ask if it's possible to fit such bag on S type Brompton without much issue? I mean have anyone tried?

1+ on firm suspension, they don't cost extra too.

The carradice city folder is only meant for M type, but it fitted ok on my S type - just have to be careful when the bags very full as it will hinder steering a little. I rarely had this problem though.
I also have the Brompton basket on my S-type and its absolutely fine.
Or are you getting one of those nice wicker ones from David Hembrow
