What maintenance do exercise bikes need?
Currently most use a magnetic brake system which does not need any type of maintenance. Nor is it necessary to lubricate any component since the internal mechanisms of the bicycle are protected and do not require maintenance. You just have to periodically check that the moving parts (pedals, seat, backrest) are correctly adjusted and if they have become loose due to use, retighten them.
As for the caution, it is important that the bicycle is always clean, so after each training session it will be necessary to wipe off any traces of sweat that may have remained on the handlebars or on the pulse sensors or screen with a clean and dry cloth without using products corrosive We must also remove all traces of dust or dirt to prevent components from being damaged.
