Hi, I'm using a Dahon 2014 model - the Horize. I got this pic off the japanese website, it gives an indication of how I sit on the bike. Is this considered an upright posture? I'm asking because I'm looking at changing the saddle to a Brooks, and some models are more suitable for upright sitting. e.g. those that come with springs and have a wider rear.
I'm not bent forward like a road bike, but I'm not sitting bolt upright like a dutch bike either. There is a slight lean forward as you can see from the photo.
