  • S / 16″ Frame – For rider height 5’4 – 5’7

If you want detail, this is where Diamondback excels. They provide a complete size chart for every model and size.

You won’t find this level of detail with many manufacturers, so if size is one of your main concerns, you should definitely consider Diamondback mountain bikes.

To make sure you’re getting the right size, you might consider having a bike fit to get some recommended dimensions. Or, online bike-fit calculators are great for working out the approximate dimensions you would need, and you can then use them to see how they compare to the sizes of the model you’re looking at.

The Diamondback Overdrive 29 3 is a great mid-level hardtail bike that has many high-quality components, without the extortionate price tag. It’s made with the same light aluminum frame as the other cheaper models, but that’s because the aluminum alloy is strong but not too heavy. It offers a range of upgrades on the cheaper 29 1 model.

Specifications and Features 

  • RockShox Judy Gold 100mm travel fork

Diamondback Overdrive 29 2 X 

Another affordable but powerful trail bike that is perfect for beginners, recreational riders, and even advanced mountain bikers. At a glance, the Diamondback Overdrive 29 2 X is rather similar to the Overdrive 29 3. They are similar in appearance, but 29 2 X has the iconic Diamondback Red paintwork. They are both on the steep side, sharing a 71-degree head tube angle. The bike is therefore nimble and a brilliant climber.

The main differences lie in the groupset and the fork. This model has the Rockshox Reba RL fork, which boasts rebound adjustment as well as remote lockout, making it perfect for a range of versatile trails and rides.

Specifications and Features: 

  • RL fork by RockShox Reba
  • Shimano hydraulic disc brakes
  • SRAM GX/NX 1x drivetrain 
  • Blanchard 25 tubeless-ready wheels


  • Several valuable upgrades on the cheaper models
  • Superior SRAM GX X-Horizon groupset
  • 180/160 mm break rotors for high functionality
  • Available in 4 sizes


  • Although tubeless compatible, bike delivered/sold with tubes


We like this bike because it’s suited for many environments. A great feature is the extra traction provided by the Blanchard 25 tubeless-ready wheels. It’s certainly a powerful hardtail 29er, and at the same cost as the 29 3, you’re getting a really good deal. We recommend this bike because it is suited to all kinds of riders, offering a good balance of affordability with quality.

For an affordable Diamondback Overdrive 29er, that’s perfect for all levels of riders, opt for the 29 2 X – you won’t be disappointed. Click here to shop for your new bike today.

Diamondback Overdrive 29C 1 Carbon 

The Overdrive 29C 1 Carbon offers many of the same parts and specifications as the other Diamondback 29ers, but it has a carbon frame, rather than aluminum. It’s aimed at riders that are looking to reduce weight as much as possible for their climbs. Not only is carbon lighter, but it’s also stiffer, making it more responsive than its aluminum counterpart.

Like the 2 X and 3 models, this XC trail bike has a 1×11 drivetrain, and it also has the same saddle, rims, tires, and brakes.

Specifications and Features:

  • Lightweight frame made of carbon
  • SRAM NX single-ring drivetrain
  • RockShox Recon Gold RL fork
  • Shimano hydraulic disc brakes


  • Carbon frame is great for lightness, stiffness and higher levels of responsiveness
  • Uses Rockshox Recon Gold, the most popular front suspension choice
  • SRAM NX Horizon groupset
  • Available in 4 sizes


  • Only available in one color
  • Higher price than non-carbon models in the range


This bike comes at a higher cost than all of the other trail bikes on this Diamondback Overdrive review – but what makes it worth the extra cash? Simply put, it’s the carbon frame. The lightness and stiffness of the carbon means that you won’t lose as much power when pedaling, and it can make a huge difference on corners. The front suspension specs make it easy to set up based on the kind of terrain you’re going to be riding on. You won’t find a comparable carbon-framed bike at this price, so if that’s what you’re looking for, we definitely recommend the Overdrive 29C 1 Carbon.

Other Diamondback Model 

There are other Diamondback Overdrive models available when you search online. The majority of these models are from previous years and come at a range of prices. These will also give you the option of choosing between 29″ wheel models and 27.5″ models. The Diamondback Overdrive 27.5 is a viable option for shorter riders, or those who prefer the ride and performance they offer. We still prefer the Overdrive 29er models, because of the high specs and features they provide.

Which Bike Should You Choose?

Hopefully, you now have all the facts that you need about the Diamondback Overdrive 29ers to make a decision! This shouldn’t be a difficult task, as all of these models are high-quality trail bikes with unique features.

For a beginner on the market looking for that first trail bike, the Overdrive 1 is truly a foolproof option. It offers a strong frame, solid build, and decent components. A real selling point is obviously the price, as it can be hard to find a high-quality mountain bike for less. If you are looking for a more advanced model that will help you improve, the Overdrive 3 offers some advancements over the Overdrive 1. We think that the top-quality SRAM components are worth the extra cost, and at the end of the day, you’re still not breaking the bank with this model.

Last but certainly not least, the Diamondback Overdrive 29C 1 Carbon is perfect for those on the market for a decent carbon frame that doesn’t cost the world. It’s the most expensive bike on this list by far, but for carbon frames, the price is actually highly competitive. An added bonus is the option to upgrade some of the components at a later date, offering a truly premium product for mountain biking enthusiasts.
