My kickstand, mentioned in a previous thread, has been working well with one problem. Because there is no stop it can rotate 90 degrees in either direction. It's a flat piece of metal so it's relatively stable but if you bump the bike from either end the kickstand folds up and the bike falls over. So I've been mulling it over and thinking of how much more complex I can make it until I found this, at Wally World, in the bike parts section, for $6.96.
