As a bike needs regular service it would be preferable if there was a possibility to add notes about in order to track what service/repair that was done and also reminders about when to e.g. do next service. For example you should do dampening service each 50 hours of ride, or your tubeless tires should be filled with new sealant each 6 months.
This could e.g. be done by make it possible to create log entries in the cycling equipment section. Also for all activities it would be beneficial if one could add a reminder with a title and a description to popup at a specific date, when used equipment for a specific amount of hours, or when used the equipment for a specific distance; this could be a multiple choice rater than a single choice, so that you can combine them, and whichever that applies first makes the reminder to popup.
