>>2021817didnt bother taking it of off a bicycle that just came with it for 4 years or so. Never used it during that time. Hardly ever bothered me, but it announces its presence audibly when going iver a bump.
Finally got around taking it off. No real difference. Only the noise mentioned above is gone.
Honestly what do people do with kickstands? If you want to stop somewhere there's usually a vertical surface you can lean the bike against. If not you can just lay it down, which is probably the best way to make sure it wont fall.
