How to Take Care of Your E-bike

Most maintenance tips carry over from traditional bicycles to electric bikes, giving you a comfortable and familiar place to start. However, since e-bikes are heavier and have additional electronic components, there are a few more considerations to keep your e-bike running in top shape: 

• Have a regular maintenance routine. Complete a tune-up before the riding season or bring your e-bike to a bike shop for an annual service. If you ride more frequently, you’ll want to follow a more regular maintenance schedule. ‍
• Keep the battery nearly full. Storing an e-bike with a dead or low-charged battery reduces overall battery life. Fully charge the battery after riding or keep it at around 80% capacity for best results. Before you ride, make sure the battery is securely locked into position.‍
• Wash your e-bike when it’s dirty. Components perform better for longer when dirt and grime are kept to a minimum. While it’s not necessary to clean your bike after every ride, a quick bike bath can help you avoid bigger issues down the road.‍
• Do the ABC check. Air, brakes, and chain. Before you ride, ensure that the tires are properly inflated, the brakes are fully functional, and the chain is sufficiently clean, lubricated, and without too much wear. An e-bike’s extra heft and speed mean these mechanical checks are even more important for a safe, comfortable ride.‍
• Refer to the manual. We know nobody likes to read the instruction manual, but e-bikes have a lot more going on than standard bikes. The model manual or setup tutorials can come in handy to adjust settings to your liking or resolve a problem with the motor or battery.‍
• Visit your local bike shop. Don’t hesitate to bring your e-bike to your local shop if you notice an issue or think something might be wrong. Expert advice from professional mechanics is the best way to properly diagnose and fix problems with your e-bike.

Washing Your E-Bike: 3 Easy Steps

A clean e-bike is a happy e-bike. Washing your e-bike not only brings out the bike’s original shine but also helps boost efficiency and reduce wear on the components. You’ll extend your e-bike’s performance by spending just a few minutes on a thorough clean every couple of weeks or after an especially mucky ride.

1. Soap and scrub
   Fill up a bucket with soapy water— dish soap or dedicated bike cleaner works great. Generously apply the soapy water across the entire bike with a sponge or soft brush, freeing up any muck and grime from the frame, wheels, and pedals. If there is a large amount of mud or caked-on dirt, you can spray the bike down with a hose first.

2. Degrease and clean the drivetrain
   Take care of the mechanical parts of your e-bike by cleaning the drivetrain with a bike degreaser. Apply degreaser to the chain, chainrings, cassette, and rear derailleur parts and wait a few minutes. Use a brush to scrub away grease or grime build-up before wiping away the remainder of the degreaser.

3. Lubrication and drying
   The final steps are lubricating your newly cleaned chain and fully drying the bike. It’s important to remove any remaining water with a dry cloth to prevent excess moisture from affecting electrical components.

For the most part, washing an e-bike follows the same steps as washing a standard bicycle, but there are a few differences to watch out for:

• Protect electrical parts from moisture. Electric bikes are highly water resistant but it’s still a good idea to switch the bike off before washing and ensure that the battery is locked into place. Check that the charger port cover is in place and remove any electric accessories that may be sensitive to cleaning products or excessive water exposure.‍
• Avoid washing your e-bike upside down. The areas around the battery and motor are designed to drain water while riding, but flipping the bike over can cause water to pool inside these parts, causing damage.‍
• Store your e-bike indoors. Reducing exposure to the elements or extreme temperatures helps keep an e-bike clean and functioning properly. Excessive rain, snow, or humidity can lead to rusted parts or water damage. Long exposure to freezing temperatures can permanently weaken the battery’s performance. 

Common E-Bike Maintenance Tips

E-bikes require the same TLC as standard bicycles, with a few additional considerations due to the motor and battery. All the basic maintenance guidelines apply to electric bikes when it comes to mechanical parts such as wheels, drivetrain, tires, and the frame. That said, e-bikes are heavier and more powerful than non-motorized bicycles and that extra force means proper upkeep is crucial. 

Check that the brakes (likely disc brakes) are operating correctly so the e-bike can come to a controlled stop. Sufficiently inflated tires will prevent pinch flats that can occur when there isn’t enough air in the tires, especially given the added weight on electric bikes. Chain wear can be more prevalent on e-bikes due to the larger power transfer between the motor and drivetrain— watch for slipping gears or inaccurate shifting.

Fortunately, motors are some of the most reliable parts on an electric bike. The closed system and maintenance-free design mean they are unlikely to require any servicing. However, issues can arise on occasion so it’s best to refer to your e-bike’s manual or a qualified bike shop in those situations.

E-Bike Battery Care

Taking proper care of your e-bike’s battery will maximise its performance and extend its lifespan. Manufacturers state that the service life of lithium-ion batteries depends on various factors such as past charging cycles and storage methods.

Many e-bikes have removable batteries to allow for on- and off-bike charging. Ideal charging conditions are at room temperature using only the charger specifically designed for your e-bike. Regularly charging the battery to at least 80% capacity helps keep the optimal level of performance. You should avoid regularly draining the battery down to zero and leaving it completely uncharged for long periods of time.

“We recommend that when you ride during summertime or you ride all year-round, charge it up after every ride so you are ready for the next ride. That way, you wont forget either. But if you’re not going to use your ebike for some time, store it at that 30-60% charge to prolong the battery life. When it’s freezing temperatures outside, we recommend charging the battery inside and store it inside because the freezing temperatures take quite a toll on the capacity of the battery and on the range of the bike.” 

—Jonathan from Bosch E-Bikes (interview with GCN)

For long-term storage, it’s recommended to keep the battery at a charge status of 30-60% in a dry environment at room temperature. This figure is lower than the 80% capacity mentioned earlier which is more appropriate for daily charging, avoiding overcharging while still providing plenty of riding range. Accessories such as “trickle-chargers” can help maintain the optimal level of charge over time without overcharging the battery. 

Over time— typically a period of several years— a battery will naturally lose capacity. When it’s time to dispose of an e-bike battery, it’s crucial to dispose of it properly to avoid environmental contamination and unsafe dumping. Sometimes you can return old batteries to the bike shop where you originally bought your e-bike. Riders can also dispose of batteries via at most local supermarkets, which have battery recycling points.

How Often Should I Get My E-Bike Serviced?

Regular maintenance checks and cleanings help prevent issues from arising, but you’ll still want to service your e-bike from time to time. How often you’ll need to visit your local bike shop for basic servicing, however, will depend on how many miles you ride and in what conditions. 

For recreational riders who ride about once a week or during weekends, a tune-up once per season should be sufficient. More frequent cyclists— such as daily commuters or high-mileage riders— will want to service the e-bike more often, around every 3 to 4 months. With heavy use, it’s natural that general wear or occasional mechanical issues will demand that your e-bike takes a visit to the shop. Keep an eye and ear out for diagnostic signs such as squeaks, rubbing, and other irregular sounds that could signal that it’s time for a check-up.

The complex electrical parts and warranty clauses of e-bikes mean that your local bike shop may not be prepared to properly service your model. It’s important to find a shop that’s qualified to work on the specific electric components on your bike if that’s where the issues are. For regular servicing or basic tune-ups, though, your local bike shop should be ready to help.

Frequently Asked Questions
