How often should I service an e-bike?

Do a quick check weekly, a closer look monthly, a deeper service each season, and a full professional service once a year or every 1,500 to 2,000 miles. High mileage or wet, muddy riding pulls all of those intervals in. The drivetrain needs attention sooner than the rest of the bike because the motor drives it hard.

Do e-bikes need more maintenance than regular bikes?

The frame, brakes, and bearings are much the same, but the drivetrain wears faster because the motor puts extra torque through the chain and cassette. On a mid-drive e-bike, expect to clean, lube, and replace the chain more often than you would on an equivalent analog bike.

How do I care for my e-bike battery?

Store it cool and dry, and keep it away from extreme heat and freezing. Do not leave it fully empty or fully full for long periods — store it part-charged following the maker's guidance. Charge indoors at room temperature and let a hot battery cool before charging.

How often should I replace an e-bike chain?

Most mid-drive e-bike chains last about 1,000 to 1,500 miles, less than a comparable analog road chain. Check wear with a chain-checker and replace at 0.75% elongation on an 11- or 12-speed drivetrain. Catching it on time saves the cassette.

Can I wash an e-bike?

Yes, but never blast it with a pressure washer, and take extra care around the motor, battery contacts, and display. Use a bucket, a soft brush, and a gentle hose, then dry the contacts and re-lube the chain. Check that the battery is seated and the contacts are clean before your next ride.

E-Bike Maintenance Schedule (Daily to Annual, by Mileage)

An e-bike is still a bicycle, so most of the maintenance is familiar: keep it clean, keep the chain lubed, keep the brakes honest. The differences are the parts an analog bike doesn't have — a battery and a motor — and the fact that the motor drives your chain and cassette harder than your legs ever could. That last point is the one riders miss: on a mid-drive e-bike, the drivetrain wears out faster than everything else on the bike.

Here's a schedule you can actually follow, built around how much you ride rather than which month it is.

The e-bike maintenance schedule

Interval	What to do
Every ride	Run the ABC check — Air, Brakes, Chain. Glance at tire pressure, squeeze the levers, make sure the chain is clean and not skipping.
Weekly	Quick check: tire pressure, brake feel, chain lube, and a look for anything loose. Wipe the frame and re-lube a dry or noisy chain.
Monthly	Closer pass: clean the drivetrain, check chain wear with a chain-checker, inspect brake pads and tires, confirm bolts are torqued, update firmware if prompted.
Seasonally	Deeper service: thorough drivetrain clean, brake and gear adjustment, check bearings and spokes, inspect battery contacts, deep-clean after a wet or muddy season.
Annually	Full professional service — or roughly every 1,500 to 2,000 miles. A shop checks bearings, spokes, cables, brakes, and the motor mount.

Wet, muddy, salty, or high-mileage riding pulls every one of these intervals in. Grit and load wear parts out, not the calendar — so a hard winter of commuting can mean servicing at half these intervals.

The drivetrain wears faster — plan for it

This is the single most important thing about e-bike maintenance. A mid-drive motor puts its torque through the chain and cassette, so the drivetrain sees far more load than it would on an analog bike. The result is a chain that stretches sooner.

A comparable clean, dry road chain might last 2,500 to 4,000 miles. A mid-drive e-bike chain often lasts just 1,000 to 1,500 miles. So shorten your drivetrain intervals: clean and lube more often, and check chain wear more often.

The rule doesn't change — replace at 0.75% elongation on an 11- or 12-speed drivetrain — but you'll reach it faster. Catch the chain on time and a fresh one still meshes with your cassette. Ride past 1% wear and you'll be buying a cassette too, which on a torque-heavy e-bike is an expensive habit. Hub-drive e-bikes, where the motor is in the wheel and doesn't drive the chain, are gentler on the drivetrain and wear closer to analog rates.

Battery care

The battery is the most expensive part on the bike, and it responds to how you store it more than how you ride it.

Store it cool and dry. Heat is what ages lithium cells fastest, so keep it out of direct sun and away from radiators.
Avoid extremes. Don't leave it in a freezing garage over winter or a hot car in summer. Let a cold battery warm up and a hot battery cool down before charging.
Don't park it full or empty. For long-term storage, leave it part-charged and follow the maker's recommended storage charge — sitting at 100% or flat at 0% for weeks shortens its life.
Keep the contacts clean and dry, especially after washing, and make sure the battery is seated before you ride.

Brakes and tires wear faster too

The chain isn't the only part paying for the motor. E-bikes are heavier and quicker, so the brakes work harder — there's more mass and more speed to haul down every time you stop. Disc brake pads are highly variable, roughly 500 to 1,250 miles on an analog bike, but heavy e-bikes and eMTBs can burn through a set in as little as 375 to 500 miles. Check the pads at your monthly pass and replace them before the friction material drops under about 1 mm, or once you hear any metal-on-metal.

Tires take a beating for the same reason: extra weight and torque scrub rubber faster, and the rear wears about twice as fast as the front. Watch for a squared-off profile, visible casing, or repeated punctures, and keep them at the pressure on the sidewall — an underinflated tire on a heavy bike wears and punctures faster.

Motor and firmware

The motor itself is largely sealed and low-maintenance — there's nothing to lube or adjust. Keep it clean, don't pressure-wash it, and let the shop check the mount and torque at the annual service. If your bike's app or display prompts a firmware update, install it; updates can improve motor behavior and battery management. That's about the extent of the rider-side motor care.

Track the miles, not the months

Every interval here bends to conditions and mileage, which is exactly why a calendar reminder falls short. A weekend e-bike rider and a daily e-bike commuter will hit that 1,000-to-1,500-mile chain window months apart, and the commuter's winter grit makes it come sooner still.

That's what Pedal Wrencher does: it connects to Strava, counts the real miles on your e-bike, and emails you when the chain, pads, or tires are due — with the shorter e-bike drivetrain intervals already baked in. It won't turn a wrench for you, but it makes sure "check the chain" lands at the right mileage instead of whenever you happen to remember.
