E-Bike Maintenance & Repairs: The Ultimate Guide

You’ve just picked up an e-bike from Bike Yard Online, and it’s quickly become your preferred mode of transport. Now let’s explore how to ensure it’s well looked after, so it stays in top condition.

If you've just bought or are considering buying an e-bike, it's important to know how to maintain it. E-bikes can be expensive, so regular care is key to keeping it in top condition.

This guide covers essential maintenance, including washing, lubricating, checking components, updating software, and caring for the battery. If you're new to e-bikes, our guide can help you get started. Whether it's a cargo, hybrid, folding, mountain, or step through e-bike, proper maintenance is crucial. Regular cleaning and servicing of the motor and drivetrain will ensure your bike runs smoothly, safely, and lasts longer.

Electric Bike Servicing

If you've invested in or are thinking about buying an e-bike, it's important to consider how to look after the motor, battery, and other components.

Regular servicing helps prevent small issues from turning into major repairs. We recommend a 30-day first service with a mechanic, who can show you how to use the gears, charge the battery, and cover basic maintenance. This keeps your bike running smoothly between services.

If the 30-day service is skipped, issues may arise before the bike is brought in, requiring an inspection. After this, check your owner's manual for service intervals - generally every 1000km (600 miles). In between, clean your bike regularly and check the brakes, tyres, and chain.

Regular maintenance is key to keeping your e-bike in top shape

First, let's cover the basics:

  • Keep your bike clean, tyres properly inflated, and the drivetrain well lubricated.
  • Check regularly for loose bolts, broken parts, and spokes.
  • Keep the battery partially charged, and never store it with a flat battery.
  • Charge the battery using only the correct charger, and store it in a cool, dry place.
  • Regularly check for software updates.
  • If there's a fault, visit a dealership - never attempt to take apart or repair the motor or battery yourself.
  • It's also important to have the electrical components inspected and serviced annually.

Why is this important?

✔️ Safety: Regular checks ensure that critical components like brakes, tyres, and the chain are functioning properly, reducing the risk of accidents.

✔️ Prolongs lifespan: Servicing your e-bike regularly helps prevent wear and tear from becoming major issues, extending the life of your bike.

✔️ Efficiency: A well-maintained e-bike runs smoother, ensuring optimal battery performance and motor efficiency.

✔️ Cost savings: Catching small issues early prevents costly repairs down the line.

✔️ Peace of mind: Regular maintenance gives you confidence that your e-bike is reliable and ready to go whenever you are.

How frequently should you service an electric bike?

Electric bicycle maintenance is similar to that of traditional bikes, but components like the drivetrain experience more wear. Regular cleaning and upkeep are crucial for optimal performance.

Dirt and mud can lead to accelerated wear, so keeping your bike clean enhances efficiency and extends the lifespan of parts. A well-maintained drivetrain ensures a smoother ride.

Checking tyre pressures is also important; under-inflated tyres can waste energy and be dangerous, while over-inflation affects comfort. Maintain the recommended pressure and adjust based on your riding conditions.

Wear and Tear of Components

E-bikes are built with stronger, specialised components to handle the added forces from increased power, speed, and weight. Drivetrains, wheels, tyres, forks, and brakes are reinforced to withstand the demands of assisted riding, offering durability and performance.

However, despite these reinforcements, it’s important to regularly check your bike for loose bolts, damaged parts, and excessive wear. Keeping an eye on your chain and other components can prevent further damage, as worn parts can affect the entire system. Regular maintenance will help you spot issues before they escalate.

How should you wash an electric bike?

Cleaning your e-bike properly is crucial for maintaining its efficiency and lifespan. While motors and batteries are sealed, avoid using a high-pressure jet wash, as it can force water through seals. Instead, use a bucket of water or a low-pressure hose, a brush, and a bike-specific cleaner. Be sure to keep the bike upright and turn off the system before cleaning. Never wash an e-bike upside down!

After washing, dry the bike with a clean cloth, avoiding the disc brakes. Check the charging ports for dirt and clean them gently with a dry brush. It's also a good idea to occasionally clean battery contacts and the speed sensor magnet for optimal performance.

How should you store and charge the battery?

Though e-bike batteries are sealed, there are still several ways to keep them in excellent condition. Lithium-ion batteries naturally lose capacity over time due to a process called self-discharge, but this is normal.

When you regularly disconnect your battery, use a damp cloth to clean it and a dry brush to remove dirt from the connections. Occasionally clean and lightly grease the battery contacts, but avoid using high-pressure water.

To maximise battery life, take good care of it by storing it properly and keeping it charged. Regular maintenance and proper handling will help prolong its lifespan.

Use the correct charger!

Charge your e-bike battery at room temperature in a dry area. To extend its lifespan, avoid leaving it fully charged or fully discharged for long periods. If not using the bike for a while, disconnect the battery but top it up periodically, maintaining a charge between 30 and 60 per cent for long-term storage, as recommended by Bosch.

Extreme temperatures can damage the battery, so store it in a cool, dry place away from sunlight. In winter, especially when it's below 0°C, charge and store the battery indoors and only insert it before riding.

Remember to bring the key if you're taking the bike to a shop for service. Always use the correct charger for your e-bike, as using the wrong one can damage the battery, even if it looks the same.

Repairs and Waterproofing

While e-bike motors and batteries are sealed, it's still possible for water to get in without proper care. Avoid using a jet wash or fully submerging the bike to prevent damage.

The motor is factory-sealed and should never be taken apart for repairs. If there's an issue, visit the store or a reputable dealer. Some insurance policies even cover battery damage.

During a service, a good bike shop/mechanic will clean the motor, check diagnostics, and update service information, ensuring no error codes are present and keeping your bike in top condition.

Extending the range of your e-bike's battery

To extend your e-bike's battery range during rides, consider a few key factors. Maintain a cadence above 50 revolutions per minute for better battery efficiency, and reduce the load on your bike to minimise strain on the battery. Riding efficiently by braking less and optimising tyre pressure will also help improve your range.

Some e-bike computers can track battery consumption, allowing you to adjust your riding style accordingly. Keep in mind that riding in cold conditions can strain the battery more and reduce its range, so plan your rides with temperature considerations in mind.

Keeping your software up-to-date

Most e-bike manufacturers regularly release software and app updates, with some providing them more frequently than others. Many proprietary apps or built-in displays not only log ride statistics but also allow you to customise your bike's performance, such as adjusting power settings for reduced battery usage. Lowering the output can extend battery life, although it may require more effort to tackle hills.

E-bike apps often provide system health updates, including service intervals, and you can check for firmware updates through connected apps or the manufacturer’s website. Some brands may recommend visiting an authorised dealership for updates. These firmware updates can enhance torque, extend battery life, or offer other improvements, making it beneficial to check for any available updates. E-bikes may also display error codes that prevent the motor from engaging, but these issues can typically be resolved by a dealership.
