Sunny Health & Fitness SF-B1805 spin bike Review 

The most desirable feature of the Sunny Health & Fitness SF-B1805 stationary bike is its strong, durable frame. And due to such a thick alloy steel frame, this stationary bike weighs a massive 125 Pounds. That makes it much heavier than most other indoor bikes in this price range. 

And thanks to the heavy frame and stronger stabilizers given on both the rear and front sides, you won’t have to worry about your safety while spinning.

Additionally, the 44 Pounds flywheel gives extra stability while riding. The heavy flywheel, in addition to contributing towards stability, combines with the advanced magnetic resistance pad to offer you adjustable resistance. 

That means, with the Sunny Health & Fitness SF-B1805 indoor bike, you can create real outdoor biking experiences within the comfort of your home. 

Another feature worth mentioning about this Sunny Health & Fitness spin bike is its customizability. You can adjust the seat and handlebars in both vertical and horizontal directions. 

That means, you can select between the inseam height range of 28-38 inches, and a seat-to-handlebar distance range of 17-21 inches

Thanks to such diverse adjustability, this indoor bike can suit both short and taller individuals. To make sure this bike suits you, do measure your inseam height, and check whether it comes within the range. 

Another mentionable feature of this spin bike is the belt drive they’ve used instead of the conventional chain drive. Due to this, not only will you have to do considerably less maintenance, but also you can have a quieter, smoother indoor cycling experience. 

Conversely, one thing you should keep in your mind is that this Sunny Health & Fitness spin bike doesn’t have a live performance monitor. That may come as quite an issue, especially if you are planning to keep track of your cycling progress. 

But as you may know, performance monitors of most other bikes are hardly found accurate or helpful. 

And, if you are planning to use some fitness app, or want to install your own device to track your performance, you can place the device on the device holder provided with the bike. The device holder is placed above the handlebars, and it will be easier for you to use your tablet, smartphone, or any other devices that you use instead. 

Other facilities with this Sunny Health & Fitness bike include protection cages for the pedals, mobility wheels to move the bike around, and a water bottle holder.

Given below is where the bike stands in terms of build quality. 

Frame

The frame of this Sunny Health & Fitness stationary bike is made of extra strong alloy steel. The frame is also heavier than that of most other indoor bikes; as a result, it weighs a massive 125 Pounds. 

Thanks to such a heavy frame, the bike can withstand a weight of up to 300 pounds. And that’s a not-so-bad number for an indoor bike. 

Therefore, unless you are very heavy, you are truly safe to ride this bike. 

Flywheel and Resistance 

If you feel like the heavy frame is not sufficient, then here is the 44 Pounds Flywheel. 

The 44 Pounds flywheel of the Sunny Health & Fitness SF-B1805 exercise bike offers great inertia and thus, will give you greater stability while biking. 

Combining with the Flywheel is the magnetic resistance pad that lets you pedal against adjustable levels of resistance. The magnetic resistance pad is designed and engineered with utmost care.

Also, unlike the conventional frictional brake pad, the magnetic pad is far more efficient, durable, and most importantly, comfortable.

Pedals

Speaking of the pedals of the Sunny Health & Fitness SF-B1805, they come with sufficient strength to withstand loads of up to 300 Pounds. They are likely made of aluminum, which makes them strong and light in weight simultaneously. 

Additionally, the pedals are placed within protection cages that will protect your feet from fast rides and other mishaps.

Handlebars

The handlebars of this Sunny Health & Fitness indoor cycling bike are bigger, and more adjustable than most other spin bikes. It is strong enough to suit varying riding styles. Hence, you won’t feel wobbling or any such issues, unless you weigh 300 Pounds. 

In addition, the handlebars have a rubber coating at the top, making it more comfortable for you to hold them. 

Seat

The seat of the Sunny Health & Fitness SF-B1805 bike comes with a dimension of 10 inches length, 8 inches width, and 3 inches height. We have no opinion that the seat of this bike has the greatest possible dimensions, but it can do the job for you. 

Furthermore, the seat is specially designed for longer rides. For instance, it has a thicker cushion, and a hole to distribute the load further.

Here is how Sunny & Health used technology while designing this exercise bike. 

Flywheel and Resistance

The 45 Pounds flywheel and the advanced magnetic resistance are among the most notable features of the Sunny Health & Fitness SF-B1805 indoor cycling bike.

Using the magnetic resistance technology of this spin bike, you can imitate real-outdoor cycling conditions from the comfort of your home. That means, you can enjoy the feel of pedaling in flat terrain, or that of going up a hill, riding down the hill, and dozens of resistance levels in between. 

In other words, the magnetic resistance is micro-adjustable. You can adjust it easily by using the knob given right within your arm’s reach. 

To increase the resistance, turn it clockwise. And to decrease it, turn it anticlockwise.

Adjustability

This Sunny Health & Fitness indoor bike is greatly customizable. Both the seat and the handlebars are adjustable in 4 ways; that is, vertically as well as horizontally.

In short, you can customize the bike in terms of:

  • Seat height
  • Handlebar height
  • Seat – handlebar distance

Belt Drive 

The Sunny Health & Fitness SF-B1805 uses a belt drive instead of the conventional metallic chain drive.

As a result, your indoor cycling sessions will be even quieter and smoother. 

Another advantage of the belt drive is that it needs no maintenance compared to the metallic chain drive.

Assembly and Maintenance

Assembling the Sunny Health & Fitness SF-B1805 indoor bike is not supposed to be tedious. 

First of all, grab the instructions manual and the toolbox that arrive with the package. 

The frame, flywheel, and some other parts will already be connected together when it reaches you. All you have to do is to connect the other parts. Their instructions manual is very clear, and you can simply follow them to assemble the bike.

Assembling the Sunny Health & Fitness exercise bike will take you a maximum of 45 minutes. Although they offer expert assembly at some locations, we suggest you do it yourself, as it is not a hard job. 

However, as the machine is heavy, it will be better if you have someone to help with moving the package.

Now, speaking of the maintenance, you need to take proper care of the bike to ensure smoother operation and better life.

Daily maintenance: 

  • Clean the frame, drive cage, handlebar, seat, and other key parts, and get rid of sweat and other dirt. 
  • Make sure the pedals are well connected, and the screws are intact. 

Weekly maintenance:

  • Inspect all screws, fasteners, and connectors. Make sure they are perfectly connected and in shape. In case of any damages, go for immediate replacement.
  • Make sure the seat is perfectly leveled.
  • Lubricate the pop-pin assemblies for a smoother operation.

Monthly maintenance:

  • Do a detailed inspection of all nuts and bolts, and ensure they are well connected. Make sure the bottle holder is also in position.
  • Inspect the brake pad. Look for any damages or presence of foreign particles. Clean the pad thoroughly, preferably after taking it out. 
  • Clean and lubricate the seat post and handlebar post.

Aesthetics and Styling 

Basically, the Sunny Health & Fitness SF-B1805 indoor bike has a simpler appearance. Along with black as the major color, a few other parts like the flywheel and the posts come with the common silver color.

Additionally, they’ve used red circles to give some style to the flywheel and the pedal cage. Finally, the brand name, ‘sunny’ is labeled in the frame. 

So, aesthetically, the bike is an average performer, and the manufacturers decided to make it simpler.
