Key Features To Keep In Mind When Looking For The Best Mountain Bike Under 300
Now that you have seen some of the best affordable options, you might wonder how we picked them. To help you look for a bike anywhere else, we have isolated some of the most important features. These features will make or break the quality of the bike and it could have a massive impact on the price as well. When looking for a mountain bike, keep these features in mind:
Frame
The frame is one of the first things that will affect the price. Whilst the steel frame is really affordable and durable, it does make the bike heavier. When you need a lightweight, yet still durable frame, the aluminum frame is definitely the best option to consider. However, it could be a little more expensive as well.
Drivetrain
The drivetrain can make or break the bike. If you have a good drivetrain, you have more comfort when it comes to riding. We recommend Shimano derailleurs if you are in this price range as they also offer excellent durability and functionality. Nevertheless, combining them with SRAM shifter will make the shifting process easy and fluent.
Size
Your bike should be the right size or you could put a lot of strain on your joints. This is much more imperative if you have knee problems. You might also consider looking for the best bike for bad knees if this is the case. We would recommend bikes of 26-inches or higher for taller and larger riders.
Wrap Up – Best Mountain Bike Under 300
Now that you have a better understanding of the cheapest mountain bikes, nothing should keep you from enjoying your hobby or even commuting around town. These bikes might not compare to the best commuter bikes, but they are versatile. We recommend any of them for mountain bike lovers and we believe you will have some fun.
