The best selling point of Release 4C is its carbon fiber-made chassis. It has several advantages over even the best aluminum-made bodies. It’s stiffer, lighter, and comes with a promise of longevity for years.

The Level Link Suspension System

As you know, suspension is the most deciding factor for a mountain biker. And with the Level Link suspension, Release 4C is going to check every box.

Because of this special suspension system, the chain forces will be completely isolated from the trail inputs. That of course stops the suspension from bobbing while you’re stomping right on the peddle.

Shock Mounting Made Easy

As we’re talking trailers and mountain bikes, it’s beyond words how important the shock mounts are. On that note, Release 4C had been taken care of with the Fox Float rear shock mount. On top of that, there is the 150mm travel from the float fork.

Therefore, the bumpy ride that you’ll face while you’re on the bike, won’t bother your comfort and focus to a good extent.

Great for Riding on Rocks and Roots

As long as it’s about mountain biking, it’s obviously the bumpy and harsh road that bothers you. Provided that the Diamondback Release 1 is backed by the industry-leading Level Link suspension, that’s going to hold you back.

Due to such suspension, the suspension becomes extremely plush the moment you hit the harsh and slippery part of the road. For any rider, that’s a blessing.

A Firm Precision in Steering

Steered a wrong way for even a second, and you’re at a life risk while it’s mountain biking. So, it’s important to keep the steering precise. And Diamondback had done exactly that with this bike.

Due to the Thru-axle front and rear, stiffness is provided to the steering system of the bike.

Tubeless Tires for More Traction

For on-road commuting, it’s a different case. But for mountain biking, tubeless tires are the rider’s first choice. With this bike, you’re getting a couple of 27.5” wheels, which are tubeless and easier to control.

A Balanced Price-point

Although we have discussed a number of Diamondback bikes in this list, this is one of those models that can be called ‘the best of both worlds. It suits well within the benchmark of 2000 dollars, and that’s ensuring every essential feature that mountain bikers want in the first place.

Buyer’s Guide for Best full suspension mountain bike under 4000

As you have gone through 5 of our best full suspension mountain bikes under 4000 in this review, it’s time to wrap things up. But before that, we would like to hone up your purchase decision with a set of buying guides at this point. This will help you to understand the basic know-how in order to pick up a good-quality mountain bike.

The Body

Although, aluminum-made frames are pretty much the most convenient standard in the industry. But if you are really looking for an ultra-durable and lightweight mountain bike, you can also think of Carbon fiber.

But compared to aluminum, carbon fiber frames come to be extremely pricey. So, considering the budget, it’s still possible to find good quality mountain bikes within budget.

The Suspension and Grip

As long as we’re talking about mountain bikes, it’s an important thing to keep in mind that those roads are nowhere near to the smooth, on-road tracks. There are bumps, rolls, and surfaces that are very hard to even walk.

So, while you’re making your choice, keep the suspension and the grip quality in mind. Keeping an eye on the suspension system and the tire would let you beware of those facts before buying.

Gear Variation

Once again, it’s another concern of a mountain biker to maintain firm control of his speed. And that directly points toward the speed diversity that a mountain bike comes with.

Brands like Shimano and Sram provide really high-end control on the gear along with a number of speed variations. On top of that, the speed transition from gear to gear also happens to be quick and swift. That’s a prime demand of any biker from his mountain bike.

The Traction of the Tire

It’s not a distant past when mountain bikers were not with so many options to choose from, as long as tire traction is concerned. But now, my friend, it’s 2020 and you can definitely ask more from your bike.

While riding on the bumpy mountains, having a set of tires with great reaction is important. Otherwise, God forbid, it can lead you to a terrible slip-down anytime, anywhere within the mountain.

The Size 

Well, as long as it’s about the size, every person has his/her own preferences. But before going with a particular size, make sure that it’s the right suit for you, your body, and your capacity for control. Otherwise, it might lead to utter discomfort instead of a thrilling ride.


FAQ(Frequently Ask Question)

1. Question: Tube or tubeless- which kind of tires provide more traction?

Answer: As long as the tire traction is concerned, tubeless tires are the clear winner here.

2. Question: What is the perk of a carbon fiber frame over an aluminum frame?

4. Question: How important is it to have precise control over the steering?

Answer: As long as the safety and smoothness of a mountain bike ride are concerned, having a firm steering system is a must.

5. Question: What are the smallest and largest size of frames of a mountain bike?

Answer: Well, that depends and varies from brand to brand. As long as the picks we’ve chosen are concerned, 17 inches seems to be the smallest one and 23 inches is the largest one.
