I have to say that it wasn’t easy to find and then decide on the best hardtail mountain bike for a budget of less than 300 USD. It is probably what most entry-level riding people would spend on a bike and we needed to ensure that you get value for money. But we wanted to ensure that you have a choice and a selection of features from different bikes.

We believe we found the best bike within the above price range in the Merax Finiss 26” Aluminum 21 Speed Mountain Bike. What we really liked is that it has very good Disc Brakes, and that is probably one of the most important points in choosing a bike. If you can’t break effectively, then you may have an accident. So breaking is critical.

This does not mean we undermine other criteria, but we wanted to start our selection with the best breaking system. We’ll tell you about other features as we continue this review.

Having excellent brakes make the selection task much easier. Now, I can safely say, and that without describing the other features that this bicycle is the real deal. If your needs are to not spend lots of bucks and still feel secure, then it surely will never disappoint you.

Who is this bike designed for

The bike is for sure a good off-road bike. In fact, some reviews say that it is one of the best 26-inch hardtail mountain bike currently available in the market. The apparent off-road prowess is also complemented by the fact that it also provides a good and smooth ride on the road. This bike is made for anyone who is average in height. And that is important for you to note. If you are tall or short in height, then this bike may not be good for you.

2. Mongoose Impasse HD 29 Inch

Mongoose Impasse HD 29 MTB

Click on the image to check the bike’s price

We selected this bike as our second pick for the taller person. If you are tall, then you can buy without worrying about your height. This 29″ bike is specifically designed for you. The Mongoose Impasse HD 29” Wheels is made for, thought-of by and designed to ensure tall people do not feel left alone. This is basically the best quality mountain bike for tall guys under 300 bucks. It comes with a 21-speed range and is reliable and durable.  These three main features are what makes this bike interesting. The reason is that if you are tall, you are likely to weigh much more than other bikers. So you need a durable two-wheeler.  But you also need reliability and finally speed to overtake your friends and reach the line first. Here is more information on this bike.

Who is this bike designed for

As I said above, the bike is sturdy and strong enough to handle heavy riders weight. It is also the best fit for the taller man. So for the tall men who love mountain riding, this bike is just what you’ve been waiting for to accomplish your mountain riding dreams and fantasies. But a strong and tall lady can always handle this bike too. Many female friends I know use it because it’s not that hard to handle. This bike is simply designed for mountain riding.

Features & Specification
  • Dual Disc Brakes
  • Quick Wheel release
  • 29-inch Alloy Wheel
  • 21 wide Gear range with SRAM Shifters
  • Hardtail Bike
  • ELEMENT Suspension Fork
  • Mongoose Aluminum  Mountain Frame
  • Has Water Bottle Holder place on the Frame

Core Features:

As per our previous pick, it is sold at a reasonable price, has a great design appearance, comes with quality & durability in mind. All of these features make this bike pretty good. When compared to the other bikes, this is the one that you should go for if you are tall. There is a couple of 29er MTB under $300 price range, but none that come close to this one. Again, I want to make sure that the message is clear, the 29-inch wheels are perfect for the taller men.

Pros

  • Comfortable seat
  • 21 speeds to run fast with a 29-inch wheel
  • Both side disc brakes for maximum stopping power.
  • Aluminum  Mountain Frame to handle heavyweight
  • Element suspension fork in front for smooth riding on rough terrain.
  • SRAM Twist Shifters with Shimano rear derailleur for smooth shifting

Cons

  • Need to adjust the disc brake at times
  • You may need to go to the nearest shop for proper assembly.

 

Final Impression:

This is a nice bike, one that will for sure not disappoint you in your riding endeavors. This is one of the best 29er hardtail mountain bikes for taller guys below $300 with 21 speed. It is just the ideal bike for any men and will perform almost on any terrain. Excellent deal on a high-quality bike. Note that there is a version that cost more than 300 USD. You can look at it, but it does not have much more features than the one we have described.

3. Schwinn High Timber 27.5″

Schwinn High Timber MTB

Click on the image to check the bike’s price

The bike is quite cheap but still, offers the features found in other expensive bikes. The Schwinn High Timber 27.5 Hardtail Mountain Bike is a bike made for your mountain riding, but less so for the road. It is not a hybrid bike where you can exercise in the hills and then take it to cycle to work. Please do not get me wrong here. It is a really good bike for cycling in trails, but on the road, it is kind of using a Ferrari on a 30 miles speed limit so to speak.

You can count on this bike as being an entry-level hardtail 27.5 mountain bike that is less than 300 dollars. And that just because it performs. Let’s get going with the main bike’s features.

Who is this bike designed for

This budget bike is designed for mountain riders who are not happy to ride in 26-inch mountain bike. Simple, isn’t it? Yeah, you can definitely count on the 27.5″ alloy wheels. I have to say that it’ll provide you a safe entry into mountain riding life. As I said, if you are looking for a bike for riding in town, we do not believe this the best one for that. But you can still use it for road, though you’ll miss out on off-road fun. The bike is near perfection for all, but we feel it has been mainly put together by men and for men. The reason is that at times it may be difficult to ride with it on the trails. No offense to our female riders, but there are bikes that seem not suitable for you. Please do not get this the wrong way, we want what is best for both male and female bikers. That’s all that we want. Note that it has two gorgeous colors, and these will appeal to all.

Features & Specification
  • 27.5″ Alloy Wheel
  • Linear pull Alloy V Brakes
  • Lifetime Support by Schwinn
  • 21 speeds with Shimano Gear changer
  • Hardtail Frame
  • 3 piece Alloy Crank
  • New Schwinn Mountain Frame
  • Schwinn  Front Suspension Fork

Core Features:

We have to accept that this MTB is versatile for off-road use and less so for cities. It can still be used as a mountain rider or for the more occasional offroad event. It’ll give your kids fun and they’ll spend energy on it knowing it is not a cheap bike. The splendid colors will also be of interest to them as they like to be seen. It has 21 speed and is made for the people who do not really like to have a 26″ bike.

Pros

  • 21 speeds to move fast
  • Alloy made 27.5-inch wheels
  • You can install a water bottle holder.
  • Shimano twist shifters for quick gear shifting
  • Alloy V brakes for maximizing stopping power
  • Schwinn hardtail frame & suspension fork for controlled riding

Cons

  • A little bit heavier for some riders
  • You may need professional assembly & tuning.

 

Final Impression:

Let me say this. What are you still waiting for? I mean this is a great bike with 27.5-inch wheels for casual offroad ride & exercise. It’s comfy, affordable and durable making this bike enviable by all. It is a decent bike for the occasional ride for a low price. I mean what more do you need? The bike is cheap, functional, nice colors and not too cheap too. You’ll make a grand entry into the mountain riding lifestyle if you get it.

This bike is specifically designed for tall individuals who want to enjoy mountain riding. So, if you are planning to start mountain riding, this is probably one of the best MTBs choices. As I said, this bike can be used by anyone but mostly tall/heavier individuals. If you are looking for a superbike, then this one could be it.

Final Impression:

Nowadays it’s hard to find a bike that built and assembled by the manufacturer. This is where this bike is great. It allows you to get the bike, and within an hour you are out there enjoying riding it. You do not need the whole day to understand how the puzzle work to assemble your bike like the other sets we described above. So if you are not great with your hands and prefer to enjoy your bike almost right away, then this bike is for you. It has some outstanding features & excellent performance. This makes the bike one of top rated 29-inch hardtail mountain bikes on the market for less than 300 dollars. And it includes a 21 gear shifter. So you can consider it as being a safe buy.

But, please note that this bike is mainly perfect for taller/heavier guys. So if you are a little shorter in height, I would restrain from buying this MTB. You’ll find it uncomfortable. Again, there are other great choices for shorter riders, all built with 26 inch – 27.5 inch wheels.
