[IMG][/IMG]I am a lot like you. I have back and neck issues. I ride H type Brompton that I modified. I have the extended seat post to which I added a brompton seat adapter pin that has quick release to allow quick removal. This allows setting the seat closer to the handlebars. I also added a quick release to the handlebars, allowing me to pull the handlebars back a bit which effects the fold. The quick releases allow me to quickly fold and place the bike into the B&W hard case for airline flights. These two mods make for a more upright position. Hopefully I can post a picture that you can enlarge.
