I wonder if you're the ones whose parts are rusty. Usually only on the chain, the disc, and the flywheel. If the car is very poor, it is 1-200 yuan bicycle rim classes will rust. In theory, the lighter the bike, the better. So now the mainstream bikes are all aluminum alloy. Some 4 thousand yuan or more of the car, basically there will be no rust place. But except the chain, so I'm talking about the chain and the flywheel.
It is easy to chain rust, and now the quality of the products is not satisfactory. Most of them are made of ordinary steel, even iron. Rust should be taken for granted. The best way is WD40, plus this, and then ride a few laps, variable speed, basically flywheel and disk, chain almost solved. WD40 is a kind of rust remover produced abroad. In fact, there are also about 12 bottles per bottle in china. And they all have lubrication.
My bike stood outside the rain now have rust, oxalic acid, hydrochloric acid, toilet cleaner, oil gun, oil, excuse me what method can effectively and safely rust, and not damage the original bicycle iron parts. Professionals enter. If the answer is detailed and valid, additional points can be added. Hope is your thing, don't search it online
