However, this post includes what to consider before buying a mountain bike for 6’5. Also, I will explain what makes the best mountain bike for a 6’5 man. Lastly, I  will recommend the 5 best mountain bikes for 6’5. So, let’s get into the post.

1. Diamondback Overdrive 29er: Best for Hardtrail

Diamondback Overdrive 29er

Highlights:

  • Hand-built aluminum 6061 T6 frame
  • Shimano 3×8 speed drivetrain
  • Mechanical disc brake & single suspension

Diamondback is a reliable brand for manufacturing the best quality bikes at affordable prices. If you wanna ride hardtails, Overdrive 29er is an excellent bike to start with. It features a 22” frame and larger wheels of 29”, so it will definitely suit a 6’5 guy. Moreover, larger wheels help you to ride with pace. What else do you want from a hardtail bike? Control? 

Overdrive offers WTB tires that are a bit plain for hardcore uphill rides. But, on country cross or gravel roads, WTB performs the best. If I talk about the mechanical disc brake, Tektro serves as I expected. If you ask me about gear shifting, you can rely on Shimano. However, the built quality of this bike is quite impressive. With high-quality aluminum alloy, you can surely expect the frame to last longs.

Anyways, the pedals, grips, and saddle seem to be of low quality. This disappointed me a little bit. But they are easy to replace. So, it’s okay what Diamondback serves overall at this price.

What I like: 

  • Overall built quality
  • Mechanical disc brake
  • Performance and control

What I don’t like:

  • The saddle is not that comfortable
  • Pedals and grips are cheaply made

2. Schwinn Traxion Mountain Bike: Best for Downhill

Schwinn Traxion Mountain Bike

Highlights:

  • Aluminum alloy frame from Schwinn
  • Shimano 3×8 speed drivetrain
  • Dual suspension & mechanical disc brake

Another famous bike brand Schwinn introduced the Traxion mountain bike. If you are looking for a proper downhill MTB, this one is for you. Though it features a shorter frame, there is an adjustable saddle and a pair of wheels with 29” diameter. Which helps it to fit a tall guy. Moreover, the wheels spin faster because of their larger periphery. This makes it an all-terrain mountain bike. You may think that’s all. But it’s just the beginning.

This bike offers wide knobby tires, which provide superb control on any terrain. Riding downhill gets even easier with the mechanical disc brakes. With a 24 speed Shimano drivetrain, you can ride uphill without any worries. Moreover, gears shift smoothly with Shimano shifters. Now it makes sense why people are calling it an all-rounder.

Anyways, I tried hard to find out its cons, but I failed. People are claiming it’s too light to last for long. I can’t agree with them. Then, they say this bike doesn’t have a water bottle mount. It can make sense but is not a solid point to complain about.

What I like:

  • The design is eye-catchy
  • Wide knobby tires provide great control
  • Excellent stoppage with mechanical disc brakes
  • Full suspension offers all-over comfort

What I don’t like:

  • Shorter frame
  • No water bottle mount

3. Huffy Hardtail Mountain Bike: Best for Budget

Huffy Hardtail Mountain Bike

Highlights:

  • Durable steel frame
  • 21-speed drivetrain
  • Front suspension

Now, it’s time to talk about something that is worth buying. You may don’t like cheap MTBs. But, for some reason, the Huffy Hardtail Mountain bike wins the hearts of the beginner. And why not?  It offers some exciting features at a low price. That’s impressive.

Let’s start with the frame. It is made of steel that is heavy yet robust and durable. Moreover, Huffybikes offer a limited lifetime offer. How cool is that?  

Well, wait for a moment. You will feel the real experience while riding on the bike. When you sit on it, you will feel comfortable with the saddle. The handle and seat post is adjustable. So, you can easily acquire your comfort zone. However, shiting gets easier with Shimano components. In addition, control gets even better with wider knobby tires. However, the rim brake is what I disliked most about this bike. But it’s okay for a 300 dollar bike.

Anyways, the Huffy Hardtail Mountain bike is suitable for casual off-road rides. Lightweight downhill riding is possible with it, but I won’t recommend it much.

What I like:

  • Robust and durable frame
  • Smooth-shifting
  • Comfortable saddle

What I don’t like:

  • Heavyweight
  • Rim brakes

4. Royce Union RMT: Best for Recreation

Royce Union RMT

Highlights:

  • Lightweight aluminum frame
  • 21-speed full Shimano drivetrain
  • Front suspension

What makes the best entry-level MTB? Lightweight frame? Shimano components? Comfortable position?

Royce Union RMT comes with everything one can expect. Rim brakes are something that you may dislike on MTB. But, it serves what it is made for. Yes, Royce Union RMT is a recreational MTB with some surprising features.

Let’s start with the frame. Its classic look and premium built quality is really impressive. Moreover, it’s made of lightweight aluminum, which significantly improves the quality of the ride. Along with full Shimano components and wide tires, the bike provides great control both on and off the road.

However, this bike comes with a long 22” frame which easily fits a 6’5 man. Additionally, it features 27.5” wheel, which rolls the bike super fast.

Anyways, rim brakes seem backdated on a  mountain bike. If Royce Union featured a disc brake, it could be the best entry-level MTB ever. Still, it’s comfortable to sit on the bike and control it. So, you can ride on-road or offroad without worry. 

What I like:

  • Premium built quality
  • Adjustable seat post and handlebar
  • Comfortable saddle

What I don’t like:

  • Rim brakes

5. Gravity FSX 1.0: Best Overall

Gravity FSX 1.0

Highlights:

  • Durable aluminum frame
  • 24 speed Shimano drivetrain
  • Full suspension

Finally, I am bringing something that is best on every side. Gravity FSX 1.0 is best on performance, built quality, and most importantly, best for money.

It’s rare to get a mountain bike with full suspension and Shimano components at such a low price. But Gravity FSX makes it happen. This bike comes with easy-adjustable dual suspensions, which absorb all the shock while riding. Thus, you can keep your body from jerking and ride with comfort. Moreover, it features a 24-speed Shimano drivetrain which ensures smooth shifting and great control.

However, the tires are a little thinner for riding downhill. But, it provides great speed on the track. Still, this bike has disc brakes. So, you don’t need to worry about the stoppage power.

Lastly, Gravity FSX is lightweight and has excellent built quality. Besides, it features a 21” frame, which is best for a 6’5 man. So, overall it’s a perfect mountain bike for a tall guy. You can ride cross-country, hard trail, or gravel without any tension.

What I like

  • Low price & value for money
  • Excellent built quality
  • Suspensions are easy to adjust

What I don’t like

  • Tires are too thin for off-road rides
  • Cheaply made grips and pedal

What to consider before buying a mountain bike for 6’5 man

Before buying a mountain bike for a 6’5 man, you must consider some parameters. This will help you to get the most suitable MTB that can fulfill your need. Let me explain these parameters.

Size & Fitting

Frame size is what the tall riders struggle with. They don’t know which size will best fit them. Well, it’s sounds difficult but easy to determine the size. Either you can check the manufacturer guideline or follow the standard size chart. Here is the standard size chart of mountain bikes for men.

Rider HeightFrame Size
4’10-5’1”X-Small (15’)
5’2”-5’6”Small (16’)
5’6”-5’8”Medium (17’)
5’8”-5’9”Medium (18’)
5’9”-6’1”Large (19’)
6’2”-6’4”Large (20’)
6’4”+X-Large (21’)

Here, you can see an XL or 21’ sized frame is suitable for a 6’5 man. So, you should consider a bigger frame like XL or something around it.

Note: In case you don’t know what frame size is, a bike frame size refers to the distance between the top of the seat tube and the center of the bottom bracket.

Wheel Size

After choosing the frame size, consider the wheel size. The wheel size refers to the diameter of the wheel. It has a significant influence on the bike’s performance. For example, a bigger wheel offers better speed. Where a smaller wheel ensures excellent control on the track. However, if you are riding hardtails or crossroads, bigger wheels are more suitable. For downhill, smaller wheels with a bigger frame are the best.

Groupset

Shimano or SRAM? This debate has gone on for decades.

Well, both are well reputed and reliable brands. I prefer Shimano for road bikes. But both play well for MTBs. So, let’s end this topic here. We should talk about the drivetrain. As you are getting a trail bike, you should consider bikes with higher gear options. For example, a 24 speed offer 24 different gear combinations. However, all combinations won’t be useful in reality. But you will get at least 20 combinations useful. Thus, you will acquire excellent control over any kind of track.

Anyways, whatever the groupset’s brand is, make sure the derailleur offers a fast and smooth shifting of gears. There is no other alternative to have a test ride for checking it.

Suspensions

Suspensions are the parts that make MTBs distinct from other types of bikes. They are either integrated into the front fork and installed on the seat tube. Their job is to absorb the shock while riding on the track. However, bikes are classified into 2 types regarding suspensions. One is single suspension, and another is dual suspension. But what do they mean, and which one is for you?

Well, a single suspension bike means there is only one suspension in the fork. It is suitable for uneven roads like gravel or cross-country. A dual suspension bike means there are suspensions on both fork and seat tube. If you are riding uphill or performing on extreme sports dual suspension bike is best for you.

What makes the best mountain bike for 6’5 man

While getting a mountain bike, you each may have different considerations. It’s pretty obvious as you have different needs too. But, I have some specific considerations that won’t vary much to you. In my opinion, these features make the best mountain bike for a 6’5 man.

Bigger Frame

As you are 6’5 tall, your legs must be pretty long. So you should get a bike with a bigger frame. If the frame is longer, you will get enough space to flex your legs. Moreover, riding will be efficient with a longer frame. Other hands, a shorter frame will cause inefficient paddling. Besides, space gets limited with a shorter frame. Thus, the legs get stuck on the handlebar. Leg or thigh injuries come next. So, a bigger frame will be best for a 6’5 tall guy.

Robust Body

It’s easy to assume a 6’5 tall guy is heavier than an average 5’8 man. So, the mountain bike must have a durable frame and excellent built quality. A carbon frame is the best choice, where aluminum is a decent alternative. Steel is also robust, but it’s too heavy. That’s why it is considered “backdated” for MTB frames. However, you may find steel forks and seat posts on some low-end bikes. But, it won’t be the best for mountain bikes.

Adjustability

Even if you get a mountain bike with a larger frame, you will need extra space for enhanced comfort. So, the bike should have an adjustable handlebar and saddle. Also, an easy-removable stem is good to have. Let me explain. Assume your legs are still hitting the handlebar. Get a longer stem, raise the handlebar and saddle. Thus, you can eliminate leg rubbing. So, adjustability makes the mountain bike the best for a tall man.

Excellent Control

Most of the time, it’s neglected. But, control is crucial for riding a bike, especially for MTB. And which part(s) control the bike? Yes, the brakes and the tires. They play a vital role in controlling the mountain bike.

Well, a disc brake is most efficient for a mountain bike. It offers excellent stoppage power and great control on the track. Nowadays, most MTBs feature disc brakes. So, don’t need to worry about it. But make sure it’s from a renowned brand. Thus, you can ensure good quality.

If I talk about tires, they should have excellent grip. However, wider tires provide better grip, where thinner tires offer higher speed. So, get a tire with optimal width.

Comfortability

Last but not least! The mountain bike should be comfortable to ride. However, there are a few factors that influence comfortability. 

Firstly, the saddle. If it doesn’t have enough paddling, it won’t be comfortable at all to sit on. Other hands, excessive padding causes unstable sitting on the saddle. Thus, it leads you to discomfort rather than comfort. So, get the saddle with optimum padding.

Secondly, the suspensions. The suspension absorbs the shocks while riding on uneven terrain. Thus, it prevents the jerk from your body.

Frequently Asked Questions

How do you tell if a mountain bike is the right size?

A standard bike size chart is a thing to crosscheck if your bike size is right or wrong. But different people have different physiques. That’s why a standard chart does not apply to everyone. So, the best way to match the size is to sit on the bike. If you feel comfortable with it, then it’s the right size. Besides, your leg should not stretch or rub with the handlebar if the size is right.

How do I know if my mountain bike is too big or too small?

You can clearly learn it after a ride. If the mountain bike is too big, stretches appear on the legs, arms, and shoulder. Thus, you get back pain after a ride. Again, in case of too small frames, legs get stuck or rub with the handlebar. Besides, wrist or knees get abnormal soreness after a ride if the frame is too small.

How do you fit a mountain bike?

If the mountain bike is too small or too big for you, it needs to be fitted. Well, you can’t cut the frame off or add a tube to it. What you have to do is to adjust the height of the handlebar and seat post. Firstly you have to loosen them. Then raise or depress them until you acquire a comfortable sitting position. Besides, you can swap the handlebar stem to get the perfect angle of shoulder while riding. However, you can do it yourself at home. Otherwise, take help from a professional if things seem too complicated.

Conclusion

Though all of you are the same in height, each of you has different needs. Considering this fact, I have recommended 5 different types of mountain bikes for 6’5 man. All have different specialties and various utilities. Which can fulfill everyone’s needs. For example, Traxion from Schwinn meets the demand of a hardcore rider. Where Royce Union RMT is enough for a casual biker.

However, if you are still confused about what you need, read the buying guide. I hope it will help you to decide what is best for you.

Anyways, best of luck, Mr. Tall.

Cheers!
