Hi Pedro,
Thank you for detailed route and fine photo. You mentioned both Strida and Dahon so does this mean you had two separate trips? Anyway I write this reply as I was thinking on my trip to Lisbon in December 2014. Unfortunately not with bicycle but a kick scooter. My hobby, geocaching makes me to visit areas which I hardly would visit otherwise. I was impressed by the high quality bicycle lane along road N247. Sorry that I can’t tell how far west I kicked my scooter, but here two photos anyway.
About the original saddle of Strida; few days after I had received my Strida EVO I wanted more comfortable saddle and ordered Brooks B67. Later in a situation I remounted Strida’s and OUCH! how terrible it this saddle fell I can ensure you. Here on forum are several discussions about various saddles.
Cheers,
Marsal
