An In-Depth Review of the Diamondback Overdrive Bike (27.5 Hardtail)

Things to Consider Before Buying a Budget-Minded Mountain Bike

Consumers looking to buy an affordable mountain bike should consider a few important aspects of their decision. First, determine what your budget is and do not max it out. You should make sure you have enough money left to purchase some important safety gear.

Also, you should determine if the bike is right for you. Although an entry-level mountain bike can operate just as well as more expensive bikes, they may not be right for everyone. Take into consideration who the bike appeals to and what features you enjoy most before making your final decision.

Who Should Buy Them

If you are working with limited funds, a trail bike, such as the DB Overdrive Sport, offers certain benefits. Because it is a hardtail bike, you will find that it is typically less expensive compared to a full-suspension mountain bike. You will often hear arguments why one is better than the other, but the hardtail is an excellent choice for budget-conscious consumers.

Anyone who wishes to save money, spend more time riding and less time on repairs and less time on setup should opt for an affordable hardtail mountain bike. Full-suspension bikes have more mechanical parts, which means more can go wrong, which would require repair time. With an affordable hardtail, you will spend more time riding mountain trails and less time on maintenance and repairs.

Who Should Not Buy Them

Since a hardtail lacks suspension, you must plan your trail rides more carefully. If you want something that is less challenging to ride, an inexpensive hardtail is not for you. If you want something that offers cushy rear support, stick with a full-suspension bike rather than an affordable hardtail.

Hardtail mountain bikes under $1000 are not for individuals who prefer an easier ride on a steep downhill or rough terrain trails. If you’re looking for a ride that is easier to handle and more comfortable on rough trails, opt for a pricier full-suspension mountain bike instead.

Features and Benefits You Get

The Diamondback Overdrive Sport 27.5 boasts several incredible core features and benefits for you to enjoy. Understanding those features and benefits will help you make your final purchase decision.


The bike offers plenty of durability thanks to the quality of its construction. When purchasing a mountain bike, durability is a primary factor. Thankfully, the Overdrive Sport does not disappoint in this category.

The bike has a frame constructed from 6061-T6 aluminum alloy, which holds in the most adverse conditions. Hardtail bikes like this one are typically known for their classic ability to offer composition strength, and the Overdrive Sport certainly does not disappoint.

If you have a bike that lacks durability, it will likely come to pieces the minute you set your tires upon a dirt or gravel pathway. You want something that can withstand bumps, twists, and turns. You need something that will not shake, rattle, and roll apart as you peddle your way through treacherous terrain.

Most importantly, you need a bike that offers enough durability so you can enjoy more time riding and less time sending your ride to the repair shop. A mountain bike that lacks durability is rather redundant, so the fact that the Overdrive Sport provides durability is a noteworthy feature.

Rugged Wheels

Another prominent feature of any mountain bike is its wheels.

You can have a solid body and easy maneuverability, but your bike lacks rugged tires and a decent wheel size, you’re going to find your trail ride rather lacking.

Fortunately, the Diamondback Overdrive Sport goes above and beyond what you would expect.

The large wheels allow you to traverse over multiple objects so that nearly no obstacle stands in your way.

Take the path less traveled with ease and enjoy the ride while doing so. The rugged 27.5-inch Kenda Honey Badger tires roll over any surface to make your ride smooth and comfortable.

Like the durability factor, you need something that has larger tires. Small tires are more for trick bikes and bicycles that you plan on riding along the pavement.

If you want something capable of traveling over pebbles, rocks, and chunks of upturned earth, you need larger tires.

Luckily, the Kenda Honey Badger tires are more than capable of giving you exactly what you need.


The gears of the bike are where the magic happens during every ride you take.

Thanks to the Shimano 9-speed drivetrain that offers twenty-seven gears, you experience an immediate transfer of power for incredible speed. Get to where you need to go, and fast, if necessary.

Want speed? With this drivetrain you got it.

You can take a leisurely ride on a mountain trail, or you can power cycle your way through for an excellent form of cardio.

If you are looking to travel quickly through a nearby path or trail, you will find that the Diamondback Overdrive Sport is more than capable.

Many hardcore mountain bikers prefer to the challenge of the trails. While there are some bicyclists who will enjoy a slow peddle down an off road pathway, there are plenty who want to push their way through and test the limits of their body and bike.

If you are among those who want to put your body and bike to the test, you need something that will give you enough speed to do so, and the Overdrive Sport does just that.

The Shimano 9-speed drivetrain holds together and delivers the power and speed that bicyclists want when pursuing the challenges of a mountain trail.


While the features of the bike seem spot-on thus far, you should know what benefits the Overdrive Sport 27.5 has to offer.

Most importantly, you are likely considering the Diamondback Overdrive Sport 27.5 because it is a high quality mountain bike for under $1000. The bike is available for $700, which is a great price considering the specs, features, and benefits.

To be fair, a more expensive bike may offer you a seat that feels a bit more comfortable when riding, but an uncomfortable seat is something you can easily fix. If you feel the seat is far too uncomfortable, try swapping it out with something else, or add a padded cover to it.

Spending several hundred dollars more on a bike with a more comfortable seat is not worth it in the long run. The Overdrive Sport gives you plenty of bang for your bike with its solid build, large tires, and easy shifting gears.
