The USS bents are out of favor, because people THINK that they are so much harder to learn. Truth is, an underseat steering bike will take longer to learn............about 20 minutes longer...that's it. My first bent was an USS Linear. It did take a bit longer to learn on it, a bit. And trust me, I'm not very co-ordinated. If I can learn how to ride a USS bent, anyone can. I ended up owning both the lwb and swb USS Linears. Loved them both!!! Sold them when my left foot "went bad," and I couldn't ride for several years.
After getting my foot fixed, I've started riding again, this time a Bacchetta Cafe, with above seat steering. Wanted to try something different.
Don't let anyone talk you out of testing a USS bent. They are great. The original Linears are no longer made, tho they do show up on Craigslist fairly often. They are again being made, by Peter the Bicycleman, out East, I believe. I've e mailed him a few times a few years ago, a very decent guy.
