I recently finished a 640 mile tour using the Tern Link P24h. I had no mechanical issues plus no flats! I loved being able to fold it and carry it on the trains with me. The stem has a really great mechanism for changing positions. It's called the andros stem. The only small negative for me is the bike is unforgiving when not on a road surface. I guess that's to be expected with Aluminum. I'm going to look for a better seat for the extended rides I'm planning. I would recommend this bike for the wider gear ratio of 21" - 107".
