Lifespan of Electric Bike Components You Should Know 

An e-bike is an investment. It might even be one of the best investments you can make. It can be considered an investment in your general finances, as it will allow you to cut down on many of the expenses associated with a traditional vehicle. It may be an investment in your health as it is a fun and convenient way to get exercise outdoors. It might even be an investment in your social life if it allows you to ride and connect with friends or family members.

Regardless of what you use your e-bike for, you should know the typical ebike life span. You should also know the general lifespan of the different components that make up your e-bike. With very little maintenance, a high-quality e-bike could easily last 3-5 years without incident. But you might be surprised to discover that with routine maintenance and care, your e-bike could last you 5-10 years.

By understanding the different parts, and how to properly maintain your e-bike, you can make sure you get the most out of your investment. E-bikes can be expensive, so continue reading to learn about the different components of your e-bike and how to get the most out of your purchase. No matter if you plan to upgrade, replace, or repair parts of your e-bike, this is the guide for you!

Motor

One common question is, “How long does an electric bike motor last?”

Most electric bike motors last between 3 to 10 years. As you can see, the motors can vary in life span but they are regarded as one of the longest service life parts. Because they are so integral to the operation of the bike, the motor can often be the root cause of needing to upgrade to a new electric bike. 

There are two different types of motors: geared hub motors and mid-drive motors. 

Geared hub motors experience a lot of friction and more wear and tear than some mid-drive motors. This is because each time the motor case rotates slowly with the wheel, the internal gear inside the motor rotates many more times at a faster speed. Therefore, geared hub motors might have to be replaced between three thousand and ten thousand miles. High quality motors may last closer to the higher end of this range. Geared hub motors are not as expensive as mid-drive motors and can more easily be replaced. If you find you have replaced your geared hub motor 3-5 times already, you should consider buying a new e-bike. At that point, the cost and hassle of replacing the motor begin to outweigh the cost of a new bike.

Mid-drive motors, on the other hand, have additional sensors, components, and a unique design. This additional complexity allows for a much longer life than gear hub motors but does come with some drawbacks. One drawback is that mid-drive motors may overheat and may rust faster when wet and not wiped off. Therefore, it is important to keep your bike and motor components dry. The second drawback is mid-drive motors are harder to replace. If you find you have replaced your mid-drive motor two to three times, you should consider upgrading to a new electric bike.

Tires

Your tires will be the only contact your bike has with the ground. This fact alone makes them worth paying attention to. Most electric bicycle tires last 1-3 years. This means between about 1,000 miles and 3,000 miles of riding. Of course, with proper speed, clean terrain, and good PSI settings, your tires will last the longest.

Assuming the frame of your bike is in good shape and nothing has been damaged, replacing tires can be easy. You do not need to replace the entire e-bike if just the tires are having problems. Problems might include a flat tire, a slow leak, or a worn tread pattern that doesn’t grip the road anymore.

Brakes

One of the most important e-bike components is the brakes. Pay close attention to the performance and suitability of your brakes often. We recommend doing a thorough inspection every few months. You will find that most brakes last 2-5 years, depending on usage. Higher-quality brakes, such as disc brakes, will last upwards of 6,000 miles, while cheaper rim brakes may only last half that distance.

An interesting fact about the design of most e-bikes is related to the brakes. Many e-bikes use integrated braking systems which connect the brakes to each other as well as the motor. This system stops the power to the motor when the brakes are applied. Because this system is interconnected, the brakes will continue working until they wear down alongside the motor. At this point, the entire system with the brakes and motor may need to be replaced which can be a difficult and expensive repair.

Batteries

Batteries are always top of mind for e-bike riders because it is where the juice comes from! It is good to know that some companies, like Himiway, offer warranties on their batteries for up to 2 years after purchase. This is good news in case something goes wrong with such an important and expensive component. 

Many batteries used for e-bikes last between 3 and 5 years. It will depend on how often you charge it, the conditions you ride and store it in, as well as the brand of battery. Lastly, the type of battery makes a big difference. For example, lithium-ion batteries can be charged around 1,000 times, nickel batteries can be charged around 500 times, and lead batteries can be charged around 300 times.

Chains

Most e-bike chains will last 1-4 years. The lifespan is highly dependent on how well the chain is lubricated and taken care of. Two to three thousand miles is a common range for chains to last on an e-bike. Mid-drive motors may only get 1,000 miles before the chain needs to be replaced. This is because the wear rate of central drive motors on the chain is high. However, mid-drive motors are generally compatible with belt drives and may be able to provide up to 5,000 miles of riding without needing to be replaced.

Display

The final component to discuss is the e-bike display. This is your view into the health of the bike. As an information console, the display will show you the speed you are traveling, the life of the battery remaining, the distance you’ve traveled, and other important metrics. The best tricks to keeping the display in working order are to keep it clean, dry, and free of physical damage such as dropping the bike.

There you have the average e-bike lifespan of various components and how to improve the lifespan of each through proper maintenance. As you shop for an e-bike, keep in mind the differences in parts quality and how long you expect to use your e-bike. A higher-priced e-bike may feel like more of an investment upfront, but the freedom from having to replace different parts often throughout the lifespan of the bike may be more than worth the price of the bike. 

Always keep your e-bike stored in a clean and dry environment to make the most of your purchase and all your different parts.
