I personally use a tail U - stand similar to those used on the 1940s/50s autocycles which is spring loaded and has a manual lock for its retracted position.

Is the online company I got it from but most lowrider suppliers seem to have something of the same design.
It has the advantage of supporting the back wheel and allowing it to spin up when the engine is started as the Tanaka is wont to do.
The Schwinn cruiser is also fitted with a single sidestand which seems usable but because of the coaster brake fitted on mine it interferes with and jams up the pedals when the bike is being wheeled so I tend to use the U stand.
