Sunny Health & Fitness Magnetic Belt Drive Indoor Cycling Bike Review

About the “Sunny Health & Fitness” brand

Sunny Health & Fitness is a Los Angeles-based importer and distributor of high-quality health and fitness products. They have over a decade of experience in this space. They also have a second office in Xiamen, China. This strategy ensures they can reach its wide network of manufacturers for the most competitive prices. 

Special Features (Pros) of Sunny Health & Fitness Magnetic Belt Drive Indoor Bike


At the time of drafting this work, the SF-B1805 is priced just under 630 bucks. By all standards, this is a bargain. Considering the level of quality you get. It’s well-built with all the important details covered. The sheer experience possible on this thing may rivals brands like Echelon and Peloton. 

In my opinion, I find it sensible to take advantage of the continually cheaper, quality IoT devices. Like wearables and similar gadgets. As long as you have a bike, you can easily customize the tech side. Say you invest $500 into a large HD display(tablet) and sensors, it still doesn’t come close to the “big boys”.


The SF-B1805 is made of industrial-grade steel. It’s extremely strong. It’s hard to see how you can bend, let alone break it. The paint job is multi-layered. It looks and feels premium. It’s also heat and scratch-resistant. You may pass this bike to your grandchildren. It also has a few quirks that improve durability.

For instance, it has wheels. This means that it never has to scratch the flow while moving. This protects the new look. Next, the base is wide. Thus, promoting stability. The flywheel is made of a Heavy-duty 44-lb piece of Aluminium. It runs silently and almost frictionlessly.

Speaking of ride quality, the magnetic resistance belt drive is natural-like. It also gets extremely resistant when necessary. This means you can never over-power this thing. You may try all kinds of tutorials.


The SF-B1805 is fully adjustable. I mean everything from the seats to handlebars. But before that. It has a massive 44-lb flywheel. It actually weighs about 126 lbs in total. This makes it stable on the floor. You’ll easily trust this thing to put out some intense workouts. It also has limb-shaped legs. It doesn’t wobble regardless of the kind of workout performed. 

The seat can be adjusted relative to the handlebars across 4 degrees. The minimum distance between them is 17” and the maximum 21”. This accommodates more users at a time. It measures 48L X 23W X 45H. This compact design makes it easy to create some space for it in the house. 

Customer Support

Sunny Health & Fitness is a reputable company in terms of quality and customer service. You may never need to contact their customer care office. Mostly because you are likely to receive a worthwhile package. They also offer a free return policy within 30-days. I find that most of the features of this bike are likely to meet the needs of any rider. 

This earns its good reception across different communities. A 3-year warranty covers the frame while a 6-month warranty covers the rest of the parts.  A detailed user manual is also available for free download on their site. It’s a simple but detailed document that can tell you a lot about the bike. 

Safety and Comfort

Most buyers have successfully assembled this bike in about an hour. The procedure is clearly illustrated with simple tools required. Which, are included. So I guess the bike can rarely be “wrongly-set” for accidental falls. In case you are worried about the flywheel flying off the bike at high RPMs, I have good news for you.

There’s an emergency brake button. It brings the bike to a halt as soon as you command it. Making it safer to use. The seat is large. I’m talking 10L x 8W x 3H inches. It’s well-padded and feels cozy. In addition to its horizontal position, you can also adjust its vertical position to fit differently-sized individuals.

The handlebars can also be adjusted in 4 ways. They are large enough for any palm size. They are comfortable to hold and provide excellent grip. With a sweat-resistant finish, the bars are easy to clean. They don’t develop any weird odors. 

Drawbacks (Cons) of Sunny Health & Fitness  Magnetic Belt Drive Indoor Bike

No app Support

Most indoor bikes in production in the last 5 years have developed some kind of companion app. Take, for instance, Peloton pioneered the whole app thing. Then soon after, other players like Echelon, who never used to have an app, now have. These platforms are not present in the SF-B1805. 

You may argue that the absence of the app keeps the cost of owning the bike down. But then again, that’s subject to personal preference.

Sunny Health & Fitness Magnetic Belt Drive Indoor Bike Buyers Guide

Indoor bikes help eliminate the complications of sticking to a gym routine. Consider the following factors before investing your hard-earned cash on an indoor bike:


Ride quality, intentions, and frequency of use are some of the things that may dictate how well a product performs. This is no news as we have always tended to associate high price with quality. And, rightly so! However, China came around and all of a sudden, everything changed.

Now you can find affordable bikes with excellent quality and customer support. Just like the aforementioned, Sunny Health and Fitness Indoor Bike. 


Spin equipment must keep you continually challenged. This is why you need more resistance levels. Such a set up ensures that even fitness junkies can feel the pump. Magnetic resistance seems to be the best technology in those regards. Combine this with a belt drive mechanism and you get a smooth ride.  

Companion App

Though not a necessity, it’s important to have a fitness companion app that works with the bike. This means that it should do much more than just a cycle. Bluetooth or ANT+ are the two ways to link with a bike. You may also enjoy a variety of spin classes available in these apps. Note that you might have to pay a monthly subscription fee. 


An indoor bike should have a steel frame. This allows it to bear more stress without distorting. It should also be well-made. All joints should be solid, rotating parts lubricated and a good paint job should give you a long service life. You should also purchase a cover to protect the bike against water and dust when stored away for a long time.


A large in-built display would be nice to have on your bike. However, they are rarely included in a bid to cut costs. Premium models do include a touch screen- they are larger colorful and fully immersive. If you miss one though, no problem. You can always use a tablet. They serve the same purpose.

Weight Capacity

An indoor exercise bike should bear the weight of its user. Check the weight limit on the product information section on the manufacturer’s website. Most bikes have a weight limit of 300 pounds. 


A quality indoor bike should have a free-return policy should you have issues with the hardware. It should also have a warranty on the frame and parts. 


An indoor bike should be easy to assemble. The process should be DIY and use readily-available tools. With a clear instruction manual, it should not take more than an hour to complete the setup.
