On one of our rare snowy winters, the underside of my cargo bike developed a serious case of rust. The front-wheel was constantly spraying a stream of salty sludge over the entire lower part of a bike. A mudflap fixed the problem. Well, not the rust, but the spray. Fortunately bikes are pretty sturdy and a bit of rust won't take them down. Mine is still doing fine over a decade later.
