This is a minor nuisance but my Windsor Oxford men's bike is always falling over with the kickstand engaged unless it's on a perfectly level surface and/or I tilt the front wheel the opposite direction of the kickstand. I'm guessing it's too top-heavy--I did install Wald folding baskets on the rear rack--but it still bugs me. Are there longer aftermarket kickstands or is there a way I can work with the one I've got to make it do its job better?
