Bikes hold up well with basic regular care, but a seasonal rhythm helps catch small issues — a worn brake pad, a stretched chain, a slow leak — before they turn into bigger problems.
Spring: post-storage check
If the bike sat through winter, check tire pressure (tires lose air gradually even unused), inspect brake pads for wear, and lubricate the chain, since old lubricant can dry out or attract grime during storage. It's also a good time to check that bolts — seatpost, stem, pedals — are still properly torqued.
Summer: riding season upkeep
With mileage adding up, this is when chain wear, cassette wear, and cable stretch tend to show up. Keep the drivetrain clean, especially after dusty or sweaty rides, and check brake pad wear more frequently since this is typically the highest-mileage season.
Fall: prepping for wetter conditions
As rides get wetter and muddier, clean the drivetrain more often than in dry summer months, and check that brakes are performing well in wet conditions specifically, since stopping distance increases on wet rims or rotors. It's also a good time to check lights are working as daylight hours shrink.
Winter: storage and protection
If the bike won't be ridden much, clean it thoroughly before storing it, lubricate the chain to prevent rust, and store it somewhere dry. For e-bikes, follow proper battery storage guidance rather than leaving it fully charged or fully drained for months. If you do ride through winter, more frequent drivetrain cleaning is worth it given salt and grit on winter roads.
