We can't avoid the bike from rusting because some parts must be metal, like the braking discs and some small screws and rings in the frame. If there's particularly bad weather ahead, then our advice is to store your Veloretti Electric inside where it can stay dry and clean. 

You can clean rust on screws and rings by mixing baking soda and water and cleaning the area with a toothbrush or a soft towel. Do not try this on your brake discs though - you need brake disc cleaner for that, and we recommend doing it every 2-3 months.
