How Long Do Mountain Bikes Last on Average?

Mountain bikes are a great tool on the trails, but you’ll want to do some work at home to make sure that they are in pristine condition to give them the best lifespan. The question of how long do mountain bikes last depends largely on the terrain you’re riding on as well as the quality of your bike.

Going downhill, for example, often will accelerate the wear and tear on certain bike components, particularly the brake and drivetrain.

A cheaper mountain bike will not be built to withstand the roughness of riding for as long as a high-end one.

After 5-10 years of use, you may start to notice that some of your components are beginning to wear down and lose their effectiveness. How long do mountain bikes last with poor maintenance? In the first few years, your tires, chains, drivetrain, and brake pads may need replacing to lengthen your bike’s lifespan.


The tires on your bike will wear out with use, especially if you tend to hard brake or tackle unfriendly terrain. Replacing the tires is pretty straightforward and important to keep your bike functioning properly.


The drivetrain can wear down over time due to exposure to rain or mud. If you don’t lubricate the drivetrain enough, it will start to suffer in performance. Similarly, the cassette as well as the chain ring teeth will eventually lose their utility.


The chain is susceptible to the elements, especially if you don’t grease it properly. Rain can cause the chain to rust, which is why you need to apply a coat of grease every now and again to slow the rate of deterioration.


The frame is one of the most durable components of a bike, but it is still susceptible to breaking down over time. If your frame is bent or cracked, it might be curtains for your mountain bike, but barring any accidents that damage the frame, it should last well past 10 years of use.


Your suspension is an important component that is constantly under stress. When it starts to break down as a result of constant riding, it will need to be replaced. The seals can crack and wear out, and dirt can reduce performance if it gets in the chambers.

Brake Pads

Naturally, you’re going to be using your brake pads every time that you ride, and regardless of what kind of brake pads you have, they will eventually wear out. Replacing your brake pads as needed is important for several reasons, but first and foremost, you should be thinking of your own safety and test your brakes regularly to make sure they are working properly.


The grips on a bike are made of rubber, and you’re constantly putting pressure on them with your hands. As such, this component can begin to break down and become more uncomfortable. Changing these out as needed will help keep your ride smoother and help you enjoy the biking experience.

Chain Lubrication

Lubricating and storing your chain properly is paramount in keeping it safe. The chain is often the first thing to go on a bike, and it can happen when you’re out riding, too. Make sure you lubricate the chain regularly—there’s not really any such thing as too much—and store it in a dry, cool place to avoid exposing it to the elements.

Drivetrain Maintenance

The gears on your mountain bike are very prone to a buildup of dust and debris. The same is true of the derailleurs and pedals, which can also suffer from rust (just another reason to store your bike indoors).

A good old fashioned clean of the drivetrain as well as proper lubrication can improve the performance of your bike and make it more likely to hold up in the long run.


Just like with your car, keeping an eye on your tires is important to stay safe on the trails. Worn tread is going to be hazardous out on the road, prompting the need for a replacement. The fresher your tires are, the better they will perform out on the trails.


Your bike’s brakes are of paramount importance on the trail and in answering the question of how long do mountain bikes last. You will need to rely on them heavily for just about any kind of mountain bike riding. Check your pads regularly for signs of wear and tear and replace them as necessary.
