Key Features To Consider Before Buying The Best Mountain Bike Under 400 Dollars

Spending $400 on a bike is not a lot, but we all want value for our money. While you can select any of the bikes on the list, there are many more to be explored. The following guide will introduce you to some of the key features. These features should enable you to spot the right features that actually make a bike worth buying.

Frame Type And Materials

One of the first decisions that any rider will need to make is the frame materials they want. While steel is the most affordable, it is often heavy. However, manufacturers try to combat this by making the fork from aluminum. Aluminum is right in between carbon fiber and steel, with aluminum bike prices varying depending on the other features of the bike.

As for the frame type, most mountain bikes made for climbing will not have a rear suspension system. These hardtail bikes might lack a bit of shock absorption, but the bike remains stable. For downhill riders, the full-suspension mountain bikes are often the best, making it easier to absorb some of the shocks.


When it comes to mountain bikes, your brakes can make the difference between a serious crash and avoiding injuries. Linear pull brakes are once again the most affordable and work for lower speeds. However, the disc brakes are the best for stopping power but will cost you a little bit extra. Disc brakes are split into mechanical and hydraulic disc brakes. The hydraulic disc brakes are reserved for high-end bikes.


Most of the bikes you come across will have either Shimano or SRAM as the producer of the drivetrain. Both of these brands are reputable, but Shimano has recently taken over most of the market. Shimano is the main sponsor of the Tour De France, which offers a lot of reliability. The shifters can be either standard or quick-fire, allowing you to quickly shift gears.

Tire Size

Regardless of the bike you choose, you want to feel comfortable when riding it. To ensure that the bike is comfortable, you will need the right wheels to ensure comfort. 26-inch wheels are common among most riders. However, the larger riders might need something bigger. If you are on the larger side, the 29-inch wheels are the best.

Wrap Up – Best Mountain Bike Under 400

Finding the perfect bike for your needs should not be rocket science. There are many helpful guides, but this one will show you how to find the best mountain bike under 400 dollars. These bikes have been scrutinized and tested, allowing you to find the one that meets your needs in the best possible way.
