Circuit Fitness Indoor Bike Reviewed

To say that exercise bikes are all the rage right now among those looking to upgrade their home gyms would be an understatement. Where they were once considered luxuries, or something that could be made obsolete by simply owning a regular bike, today’s stationary bikes are an essential part of any home gym setup. A stationary bike like Circuit Fitness indoor bike.

With that greater prominence has come greater expectations. It isn’t enough to simply offer a bike that can be pedaled in place. Modern stationary bikes have to offer all manner of special features to try and convince users that they offer a superior workout experience.

With that in mind, let’s take a look at the Circuit Fitness Indoor Bike and see how it measures up to these elevated expectations for stationary bikes.

One of the first things you always want to look for when choosing an indoor fitness bike is the quality of the construction.


You don’t want an intense workout to come at the cost of your bike, especially given how costly a stationary bike can be. Thankfully, quality construction is one of the best things the Circuit Fitness Indoor Bike has going for it.

The frame boasts steel framing that is incredibly sturdy. In addition, it features powder coating, which helps make it easy to grip while adding to the long-term durability.

Related to that, one of the biggest concerns when purchasing a stationary bike is its carrying capacity. Breaking a bike because you’re too heavy can be an embarrassing, costly mistake. This model can carry riders who weigh up to 300 lbs, which is just a bit above average.


In addition, this model comes with a manual resistance system that allows you to change between different amounts of resistance. This is an essential component of most modern stationary bikes, allowing you to determine how much resistance you want to work against while pedaling and, thus, how intense you want your workout to be.

That amount can and likely will change over the course of your workout. For example, you’ll likely want less resistance during your warmup and cool down periods than you do for the bulk of your time on the bike.

Chain Driven Mechanism

To that point, the Circuit Fitness Indoor Bike boasts 40 lbs’ worth of resistance, which is about on par with many fitness bikes on the market. It also comes with a chain drive system that helps change gears and manage this flywheel.

While operation is consistent and smooth, it is not as silent as magnetic options that are practically whisper-quiet. That said, it isn’t raucously loud, either, so while it may not be quiet enough to pedal beside someone sleeping, it shouldn’t wake up the whole house, either.


Another vital aspect of any fitness bike is its seat. Few things disincentivize riding on a stationary bike like having to deal with a sore rear due to a stiff, uncomfortable seat. Thankfully, this model boasts a two-axis saddle seat that is thickly padded. Those axes also make this seat easy to adjust, which is good for family use with different riders of different shapes and sizes.

The handlebar likewise features a soft, comfortable grip, and the pedals offer good footing while pedaling. Between the handlebars you’ll find a place to put your iPad or other device as well as a water bottle holder for added convenience.

What Do Users Say

Circuit Fitness Indoor Bike

One of the most important aspects of any stationary bike experience comes right at the beginning as you put it together. Nothing sours the stationary bike experience like struggling through a long, tedious, frustrating assembly process.

Luckily, this model eschews that problem.

That ease of assembly points to the most overriding aspect of the user experience for this bike – its accessibility. If you have never owned a stationary bike before, this isn’t a model that is likely to overwhelm you. It is as easy to use as it is to assemble, with features clearly delineated. You won’t have to fiddle with any computer controls or app connectivity.

On the one hand, that streamlined design may be a bit disappointing for those looking for a more robust riding experience.

On the other hand, it may come as a relief to those looking for a more accessible first bike, or for those who want a no-frills riding experience. The latter audience is clearly the target audience for this bike. On the whole, therefore, this bike offers a very accessible and streamlined riding experience.

Our Rating: 4.2 Star Rating 4.2 / 5

The Circuit Indoor Fitness Bike ticks many of the boxes that are expected for a modern exercise bike.

While it may meet those expectations, however, it does not always surpass them. It does not have the kind of advanced stat-tracking technology or app connectivity that is featured in many of the true top of the line stationary bikes on the market. Riders looking for a state of the art experience may find this bike a bit lacking, and, thus, may want to look at more advanced bikes.

That being said, this bike isn’t necessarily meant to compete with those bikes. Rather, it is designed to be a streamlined stationary bike that can serve as a good entry point for new riders and a serviceable affordable option for more advanced riders. In that respect, it mostly succeeds.

One of the most important aspects of healthy fitness is knowing how to manage your expectations. It is unfair to expect the average person to be able to be as fast as Usain Bolt or be as great at tennis as Serena Williams or Roger Federer.

As long as you know what to expect with this bike, it can make for a great ride and exercise experience. If you would like to get your hands on a similar bike, yet with 330 lbs weight support, check out Cyclace indoor bike. You can also check our complete guide on affordable exercise bikes.
