E-Bike Maintenance Schedule: What to Check and When

E-bike makers set service by distance or time, whichever comes first, and the figures differ by brand. Riese & Müller says the first service is due after 400 km at the latest, then every 2,000 km or one year from the date of sale. Ecoride lists a first service at approximately 500 km or six months, then around 4,000 km or one year. Halfords recommends an interim service every six months and a major service once a year. Between services, you look after the same parts as on any bike, with extra attention to the drivetrain, the brakes and the battery.

The short version, as an e-bike maintenance checklist:

1. Follow the service intervals in your owner's manual, and use the dealer's figures if the manual gives none.
2. Lubricate the chain often, and check tyre pressure and brake feel regularly.
3. Check the battery charge before each ride, and clean the bike with a low-pressure method only.
4. Store a battery you are not using at a partial charge, as your maker describes.
5. Leave the motor, the battery and the wiring to a dealer.

Every figure here comes from an e-bike maker or an independent source, and we name it. Where figures vary by brand, we say so and send you back to your manual. We give no electrical procedure of our own: follow the maker's manual for the motor and battery.

What Is Different About E-Bike Maintenance

BikeRadar's e-bike maintenance guide says that in many senses, electric bicycle maintenance is no different from that of a non-assisted bike. The differences are about load and about the electrical parts.

The drivetrain

BikeRadar says some components, and particularly the drivetrain (cranks, chain, cassette and freehub), are subject to greater forces and increased wear. It adds that electric bike chains tend to require more frequent lubrication than non-assisted bicycle chains, and suggests lubricating after every ride, and certainly after washing and drying the bike.

BikeRadar also says that if one part wears out, such as the chain, it can cause premature wear to the chainrings and cassette. That is the same reason we cover chain wear in when to replace a bike chain, and it matters more when the drivetrain works harder.

The brakes

Bike Perfect, in a 2021 piece on e-bike running costs, says brake pads might require an accelerated cycle of replacement, and that e-bikes are severe on brake pads and systems. Bike Perfect gives no interval. Riese & Müller's service workshop offers a simple check: if you can pull the levers so that they almost touch the handlebar, the brake pads probably need to be replaced.

The tyres

BikeRadar says under-inflated tyres are potentially dangerous and can also waste power, so you get less out of a battery charge. Its starting point is to keep your tyres inflated to within the recommended pressures indicated on the sidewall.

The motor and the battery

BikeRadar describes the motor as a factory-sealed unit that you should never attempt to take apart. Trek says the battery, motor and controller are sealed and not meant to be serviced with standard tools. So you maintain the mechanical parts, and a dealer maintains the electrical ones.

E-Bike Maintenance Schedule: What to Check and When

This table lists only intervals that a maker or an independent source states. Each row names its source. Where no source gives a number, the row says when in plain terms.

The maker figures disagree, so treat them as examples and not as a universal rule. Riese & Müller and Ecoride both write distance and time into the interval, and both say the manual or the warranty terms decide what applies to your bike. Ecoride notes that many retailers and workshops program a service reminder in the display after a certain riding distance. Specialized describes service reminders on MasterMind-supported Turbo bikes that show on the display and in its app for scheduled services such as an Inspection Check, a Health Check, an Annual Service and a Total Service.

Chain, Brake, Tyre, Bearing and Suspension Intervals

We do not repeat the wear limits and intervals for the mechanical parts here, because each has its own guide. Check whether your e-bike maker gives a different figure for your model, then use these:

• Chain: when to replace a bike chain, the best chain lube and how to clean a bike chain
• Brakes: when to replace brake pads, why bike brakes squeal and hydraulic brake fluid
• Tyres: when to replace bike tyres, tyre pressure and tubeless sealant lifespan
• Bearings: wheel bearing service intervals
• Suspension: suspension service intervals
• The whole bike: the bike maintenance schedule and the bike tune-up checklist

E-Bike Battery Care: Charging, Storage and Cleaning

Battery care comes from the makers. Tern's guide covers Bosch batteries on its bikes, and Trek's page covers the batteries on Trek and Electra bikes. Your own manual outranks both.

Charging

Tern says to only use an e-bike charger certified by Bosch for your battery type, to keep capacity loss from repeated charging as low as possible. BikeRadar gives the same rule in general terms: use the charger specific to your bike, because an incorrect charger could damage the battery.

Tern says to charge the battery at room temperature (roughly 20°C, or 68°F), on a flat surface, in a dry, clutter-free location where a smoke detector is installed. It also says to disconnect the battery and charger from the power supply after charging.

Trek says its chargers will not charge a battery when temperatures are below 32F, and that its batteries perform best between 60°F and 80°F. Trek also recommends topping off the charge often, and says the old advice to drain a battery completely applied to older NiCad-style batteries and not to lithium-ion e-bike batteries.

Storage

Trek recommends a 40% to 60% charge if you plan to store a battery for more than 30 days. It says leaving a battery stored at 100% for more than a year can cause you to lose approximately 20% of its capacity.

Tern gives a similar range for Bosch batteries: charge to approximately 30-60% before storing, because prolonged storage at a fully charged or fully discharged state can shorten the battery lifespan. Tern also says not to store the battery connected to the charger, and to check on a stored battery regularly and charge it back into the range if needed. Its storage temperature limits are no lower than 0°C (32°F) and no higher than 40°C (104°F).

The two ranges differ slightly, which is why your own manual is the final word.

Cleaning

Trek says never to use a power washer on an e-bike, because the high pressure can cause water damage to sensitive electric components, bearings and lubricated parts. BikeRadar suggests water from a bucket or a low-pressure hose, a brush and an optional bike-specific cleaner. It also says to turn the ebike system off before washing it and to unplug it from the charger.

Tern says to remove the battery from the e-bike and use a damp cloth or sponge to clean the battery, and that the battery must not be submerged in water or cleaned with a direct jet of water or high pressure hose. Tern also says the battery terminals should occasionally be cleaned, and that your e-bike dealer will help if you are unsure how or what product to use.

What to Leave to a Dealer

Riese & Müller says e-bikes are technically complex modes of transport, the safe use of which depends largely on regular maintenance by trained specialist personnel. Ecoride says electronics, motor control systems and other advanced components require professional expertise to be serviced correctly, and that taking the bike to an authorised workshop is often a requirement for the warranty to remain valid.

In practice, the makers point to a dealer for these jobs:

• Opening or repairing the battery, the motor or the controller. Trek says not to open any of them, and Tern says opening a Bosch battery will void any and all warranty claims against Bosch.
• Motor service. BikeRadar says a good bike shop will remove the motor in a service, then clean and service it.
• Checking battery health. Tern says to bring a Bosch battery to a certified Bosch e-bike dealer or service center to find the state of the battery.
• Firmware updates on some systems. BikeRadar says some brands recommend an authorised dealership for any updates.

You can still do the mechanical work yourself, and Trek says you can work on the mechanical components of your e-bike like a standard bicycle. For anything electrical, follow the manufacturer's manual.

Frequently Asked Questions

How often should you service an e-bike? It depends on the maker. Riese & Müller says every 2,000 km or one year from the date of sale, whichever comes first, after a first service at 400 km at the latest. Ecoride lists services around 4,000 km or one year, 7,500 km or two years, and 11,000 km or three years. Halfords recommends an interim service every six months and a major service once a year. Check your owner's manual for your bike.

Do e-bike chains wear faster than normal bike chains? BikeRadar says the drivetrain is subject to greater forces and increased wear on an e-bike, and that e-bike chains tend to need more frequent lubrication. It gives no wear figure. Our guide to when to replace a bike chain covers how to measure wear.

How do you store an e-bike battery? Trek recommends a 40% to 60% charge for storage of more than 30 days. Tern says to charge a Bosch battery to approximately 30-60% and not to store it connected to the charger. Follow the range in your own manual.

Can you pressure wash an e-bike? No. Trek says never to use a power washer on an e-bike, and BikeRadar recommends a bucket or low-pressure hose, with the system turned off and unplugged from the charger.

Can you service an e-bike motor or battery yourself? Makers say no. Trek says not to open the battery, motor or controller, and BikeRadar says never to attempt to take the motor apart. Take electrical faults to a dealer.

What is the difference between an interim service and a major service? Halfords uses the terms: an interim service every six months and a major service once a year. Ecoride and Riese & Müller use distance and time milestones instead. Ask your dealer what each visit includes.

How Componentry Helps You Keep to an E-Bike Maintenance Schedule

Several makers write their intervals as a distance or a time, whichever comes first. In Componentry you can add a reminder to a bike or a component by distance or by time, so you can set one of each for the same job.

Componentry syncs your rides from Strava, Garmin and Wahoo and adds the distance to the components on the bike you rode. When a service is done, log it on the component, and each component keeps its own history, so you can see when the chain, the pads or the tyres were last attended to.

For the wider routine, see the bike maintenance schedule and the bike tune-up checklist.
