I've tried the Pletscher and another model of double stand on my commuter. The Pletscher died after one year of use due to road salt corroding the spring and getting into the pivots. The second lasted a year and a half for the same reason. I now have a cargo bike,so I don't need a stand on my commuter any more. My Big Dummy has a single arm kickstand,but it works just fine with the extended wheelbase,and I'm not dropping the crazy money for the dual-legged model Xtracycle makes.
