Step One is to edit your belongings down to the essentials. Only keep gear that is in tgood condition. For things you’ve kept strictly because of sentimental value, take a photo as a keepsake before getting rid of them. Once you’ve elminimated duplicates and damaged gear, organize what’s left by frequency of use.
Daily - (“A Space”) Need your bike gear every day? Kit it (plus multipsport items, like a hydration pack) close at hand on a hook or shelf by the door.
Weekly - (“B - Space”) Items you use frequently should be accessible, yet out of the way. Store these in a well-labeled box at eye level or below.
Seasonal - (“C - Space”) Group this gear by season, labeled in a box or bag, and stored away during most of the year. Create inexpensive stroage space in an apartment by thinking vertically: install shelving units and matching bins or use a shelving rack if you don’t want holes in your walls.
