A Critical, In-Depth Review of Breezer’s 2012 Thunder Sport Hardtail MTB

Things to Consider Before Buying A Budget-Level Bike

If you’re searching for a budget-level bike, you’ll need to first understand that budget shouldn’t simply mean “cheap.” The goal is to hit the highest value point where you wind up with a dependable, versatile bike without breaking the bank to get it.

Who Should Buy One

A budget-level bike makes the most sense for riders with less experience who are less likely to take on more challenging trails and terrain. Bikes like these are good options to get your feet wet without being too bare-boned or too close to the “newbie” side of the spectrum.

Buying a budget-level bike isn’t for beginners only. Bikes in this range make the most sense for riders who have general experience and are looking for a quality bike, but aren’t looking for all of the bells and whistles that accompany higher-end models or bikes designed for the most challenging trails.

Who Should Not Buy One

Budget-level bikes make less sense for more experienced riders who plan on riding on trails that are much more difficult to navigate. Riders in this category are likely to end up unhappy with their purchase once they realize that their bike isn’t as maneuverable or comfortable as they need it to be.

No one should spend more than they need to on a mountain bike, but it’s also important to be sure that your bike is going to be able to withstand the rigors of your riding tendencies.

What Is The 2012 Breezer Thunder Sport?

The 2012 Thunder Sport is a mountain bike made by Breezer Bikes. This model was designed by legendary bike designer Joe Breeze. Breeze is often considered the father of the modern mountain bike, and this model shows just how true that is.

The Thunder Sport is engineered for maximum performance and just as much fun. It promises to give you a lightweight, responsive bike that is ready for any trail. It’s a perfect balance.

Many people compare the 2012 Thunder Sport with the 2014 Thunder One. However, it is important to understand that the 2014 Thunder is a single-speed mountain bike while the 2012 Thunder Sport is a 3×9 speed.

Features and the Benefits You Get

The basic specs don’t fully capture what this bike is. When you purchase a 2012 Thunder Sport, you get a bike that is filled with awesome features. Below are some of my favorite parts of this model.

Good Looking

I don’t know about you, but I don’t want to ride a bike that I don’t want to look at. The 2012 Thunder Sport checks the “style” box with a modernized version of a classic design. It just feels great when strangers notice and compliment your rig.

Great Frame

Of course, I wouldn’t love a bike that’s all style and no substance. Luckily, the 2012 Thunder Sport backs up its perfect design with a body that performs as good as it looks. The hydraulic disc brakes, 6066 aluminum body, and integrated head tube all make for excellent handling, even around tight corners.

It’s also great for pushing through tough climbs and rising to the top. It can maximize your efficiency and keep your going for longer.

Smooth Shifting

If you’re like most mountain bikers, you absolutely hate getting stuck in a gear when you are trying to shift. Of course, this only happens at the worst possible time. That’s less likely to happen with the 2012 Thunder Sport.

This bike comes loaded with a Shimano 3×9-speed Acera drivetrain. This renowned drivetrain makes switching gears simple, so you don’t get stuck at the wrong time.


Because it’s made of aluminum, this bike can be quite lightweight. Of course, this depends on the tires and accessories you choose. The lighter the bike, the faster you can go.

D’Fusion Tubing

Mountain biking can cause stress on your joints and your bike. That’s why the geniuses at Breezer included D’Fusion tubing on this and other models. This tubing spread the stress wider so that no one part of you or your bike gets all the heat.

By defusing the stress, this bike keeps you going for longer and helps you avoid burnout. Plus, your bike and its parts can last longer. This revolutionary tubing is a must-have.

Breeze-In Dropouts

You can find plenty of signs of the Breezer brand throughout this bike. One of the best touches is the Breeze-In dropouts. This protective shell make your bike firmer without adding any weight. In fact, these dropouts are lighter than other, less protective ones on the market.

What Makes This Bicycle Unique

Plenty of bikes can boast these features. So what makes this one so special? It offers plenty of benefits that are sure to satisfy.

Great Price

When it comes right down to it, you shouldn’t pay more for a bike with the same features. No matter where you buy, you can typically find a 2012 Thunder Sport for a reasonable price compared to others. A great price is especially important to new mountain bikers who may not be ready to commit to a more expensive ride yet.

Climb Faster

If you’re struggling with your climbing, the 2012 Thunder Sport may help. Its light weight and great engineering make it a great climber for steep trails you have yet to conquer. You can finally reach your highest peaks and smash your goals.

Corner Better

Nothing sucks quite like eating dirt from taking a corner all wrong. This bike is relatively easy to handle, so even inexperienced riders will have an easier time cutting corners. You can stop wiping out and start taking corners with style.

Descend Faster

If half the reason you climb the mountain is come descend quickly, you’re in luck. This rig like to go fast. By shifting gears, you can get the control you want on the downhill.

The easy handling makes that a little safer, too. The 2012 Thunder Sport responds to you, so you can go down the mountain with confidence.

The low price might just be the best part of this bike, in my opinion. You can grab a 2012 Thunder Sport for just $499. It’s hard to believe you can get such a great ride for such a relatively small price.
