Diamondback Alternatives

If you didn’t find a Diamondback MTB you like from the above list, you could look at other options. We have compiled a list of 3 great options to help you decide. Check out our list of 3 bikes that are great alternatives for the above Diamondback MTBs.

Pivot Switchblade – Best Overall

Pivot Switchblade

The Switchblade is described as one of the most fun, precise and maneuverable MTB you can find in the market. This model has been one of the best from the company for quite some time. The 2021 model has seen a significant change when compared with previous versions.

One of the changes is a progressive geometry that makes the mountain bike more agile and adept in different riding situations. The rig comes with straighter tubes featured in a compact frame. Combining these features results in a stiffer and lighter bike, with more standover height on all its sizes. You get a bike that is easier to handle in challenging trails.

A longer dropper post is accommodated thanks to a steeper seat tube. There is enough room in the frame’s main triangle to fit the company’s new bike-mounted tools or a water bottle cage. It’s the result of using a DW-Link shock-mounted upside down.

The gear range is sufficient to allow you to manage the steepest climbs. For downhills, the extra-wide Superboost rear triangle and suspension design work wonders. The combination allows you to overcome rider failures and big obstacles on the trail.


  • 142mm rear and 160mm front suspension
  • Agile hill climber
  • Carbon frame
  • Sufficient space for a water cage or bike-mounted tools
  • Extra-wide Superboost


  • Pricier than others with similar features

Schwinn Axum – Best Budget Alternative

The Axum uses mechanical brakes that have sufficient stopping power for various scenarios. This type of disc brake is a more affordable option than hydraulic disc brakes and is low-maintenance. They have significantly more stopping power compared to rim brakes.

Unlike what you see on most cross-country bikes, this model has 2.6-inch wider low-profile tires. The additional road contact gives you a stable feel that inspires you if you are a beginner. It also has 29-inch rims that are great for smoothing out the terrain. Even though wide tires add weight, they stabilize the bike and make rolling over smaller obstacles fun.

  • Large 29-inch wheels
  • Above-average stability
  • Low maintenance mechanical brakes
  • Affordable


  • Available in one size only

Rocky Mountain Growler 60 – Best Hardtail

Rocky Mountain Growler 60

If you love singletrack and you are tight on funds, then this is the bike for you. Rocky Mountain designed it with bells and whistles that ensure you experience a compromise-free ride. Some features include an SRAM 11-50T Eagle cassette with 12 speeds, dropper post, and high-quality RockShox 35 Gold RL offset fork (140mm, 44mm).

When it comes to geometry, the Growler has a similar geometry to a full-suspension enduro bike. The upside is it comes without the rear-end squish. Other features include a 1,237mm wheelbase rolling on 2.6-inch tires, a 470mm reach, a 75-degree seat tube angle, a 64-degree head angle, and 29” wheels.

With such specs, you can easily power through roots and rocks. You also have the choice of getting in the air to clear a few doubles before railing the next berm. Take note moving from a full suspension to a hardtail bike is not easy.

Growler uses 2.6-inch WTB Trail Boss tires to help take the edge off. If you need spring to your climbs, the stiff frame will do just that. A combination of 29” wheels, grippy and fat tires, and slack geometry give the MTB more guts than you would expect from a hardtail. However, it’s not as gutsy as full-suspension mountain bikes. To soften the ride, consider running low tire pressures.


  • Slack enough for technical riding
  • Affordable
  • Lightweight aluminum frame
  • Large 29” wheels
  • Requires less maintenance


  • Heavy for a hardtail MTB

Factors to Consider when Choosing a Diamondback MTB

The following are tips you should consider when you are purchasing a Diamondback mountain bike:

Frame Size

It’s not a daunting task finding the right frame size to suit your riding preference. For most bikes, you just need to decide whether you want small, medium, or large. It doesn’t matter whether you are riding on the road or you are on a trail. The frame size always impacts your riding comfort and experience.

Standover height is mainly used to measure the frame size to suit your needs. It’s used to measure how tall the bike will be. Ideally, you need a clearance over the frame irrespective of the type of bike. Diamondback and other major bike labels have a size guide to help you decide on the best frame size for your height.

The standover height is the primary measurement used to size road frames. It is simply how tall the bike is. You will want a clearance over the frame, no matter the style of the bike. Every bike usually has a size guide manual to go along with it.

Seat Height

One of the most critical adjustments you make right off the bat is having your seat at the right height. Most beginner riders have their seats too low, which, apart from causing fatigue or even injury, reduces the bike’s performance. Additionally, it’s dangerous and uncomfortable to ride a bike whose seat position is too high.

To set the seat height, stand flat-footed next to the bike. Ensure the seat touches your hip bone. This offers the best baseline height. Make sure the bike free-stands with the assistance of either a wall, a friend, or a resistance trainer.

Your leg should be locked out with your heel above the spindle when your pedal is at six o’clock. When the ball of your feet is moving above the spindle, you should spot a slight bend at the knee. You need to lower your seat a little bit if your hips rock when you pedal.


Proper reach is crucial to all riders. The reach is too far for you if the bars cause your arms to lock out. In such a case, you easily end up with tingly arms and/or a stiff neck. The worst-case scenario is when you lack sufficient control of the bike.

It’s easy to risk interfering with your body’s movement and response when your reach is too short. Too short a reach results in various problems. For example, you risk getting a sore back that may lead to serious back problems.

Try to adjust your saddle setting to the point your elbows are slightly bent. It’s also advisable to note that straight elbows will not absorb road bumps and vibrations. Ensure that you always try to maintain a straight back while riding. The idea is your upper arms need to be positioned perpendicular to your torso. Ideally, you need 45 degrees to be the angle of choice. This makes it one of the best and comfortable riding positions.


You may find it necessary to change some parts of your new bike after riding for a few miles. Saddles lack a break-in period, although they are sometimes not compatible with specific riders. At the same time, challenge yourself by trying out an old saddle or even experiment with different stem heights and lengths. A significant difference comes through a few changes to bring about ultimate enjoyment and comfort.

For expert tuning, you need to visit a bike fit professional. Alternatively, it’s a great idea if you have the knowledge and means to do this. You can also get the best components by spending quality time tinkering with your setup manual.

By personalizing your bike and always listening to your body, you can get the most out of your rides. Any adjustments that you make on your bike should be made knowing the changes are reversible. It’s your bike, and you should strive to ensure it’s adjusted to give you the best riding experience.

If you are looking for an affordable full-suspension MTB, then Atroz 3 is the best choice. It has a combination of SRAM and RockShox, which is rare at this price point.
