Ok, here it is: my review (as I promised) of my Actionbent Jetstream II USS SWB after commuting with it for over 3,000 miles. This is my first bent, so I can't compare it to other bents (sorry.)
Overall, I love the bike. It's extrememly comfortable, carries loads confidently, is fun to ride. I had to go back to a DF bike temporarily, and when I got back on my bent, I was home again. Don't plan on switching back to a DF as my primary transportation. It ascends hills well, although the slow climbing of steep ones can challenge newbies on the balance issue. The price is hard to beat, too.
I found customer service (Randy and Steve at Actionbent, distributors for this Taiwan-made TW Bents model) to be excellent. On a recent problem, they went overboard to make me a happy customer, and they didn't drag their heels. Good businessmen, good to deal with, they really want to make their company stand up for the long haul by backing up what they sell.
On the negative, more toward the manufacturing side, I found some design/quality issues that need addressing. The metal seat frame experienced excessive stress underneath the seat where it bolts to the main frame tube. The bike is supposed to take a rider up to 265 lbs., but even my small person was enough to cause failure of the seat frame through normal use. After the failure, Actionbent was fast acting--they offered me either a new seat or a total refund, my choice. I choose to keep the bike.
