Key Features

There are a lot of things that you have to think about when it comes to exercise bikes, and one of the essential things you need to take notice of is the key features that play a part in this.

So let’s take a look at some of the key features to love about this bike so that you know what to expect when it comes to buying it.

44 lb Flywheel (20kgs)

With an indoor cycling bike, the heavier the flywheel, the smoother the ride. So as you might imagine, the SF-B1805 is a heck of a smooth ride! This flywheel is engineered for strength and stability to create more momentum for longer periods of time, and this makes it hugely important. Say goodbye to jerky and out of control movements; this flywheel will make you feel as though you are riding outdoors!

4-Way Adjustable Handlebars

The 4-way adjustable handlebars, complete with convenient device holder, make for a comfortable and user-friendly way of tracking your fitness. You can have your device in use during your entire work out session, and this is a vital part of the workout experience.

Magnetic Resistance

Magnetic resistance provides easy and fast changes to the resistance level, and the closer the magnet to the flywheel, the greater the resistance. This is important for increasing the intensity of the pedalling, as well as creating a low-maintenance, silent, and stable cycling experience for you.

Micro-adjustable Resistance

With a simple twist you can achieve micro-adjustable resistance, which will help you to adjust and change the intensity of your workouts to improve cardio and get a better all-round session. This is an important component, and one we think makes this model stand out in a big way.

Extra Features

So we know what the key features are, and this gives us a great starting point when trying to analyse what works and doesn’t, as well as making a decisive choice about what it takes to improve this.

But there are also additional features we’d like to mention that we like with regards to this bike. Some of these features might seem small or insignificant, but they still contribute to everything we like about this indoor exercise bike.

Water Bottle Holder

A water bottle holder is only a small detail, but it’s one that still contributes to the entire workout experience. So it’s great that the bike has one for you to stash your water bottle, and to be able to keep hydrated as much as possible during your workout experience.

Floor Stabilizers

Adjustable floor stabilizers add an additional layer of security and safety, and prevent the bike from moving around when you are trying to use it. Ideal for those seeking a more intensive workout that can also be as smooth and effortless as possible.

Steel Toe-Cap Pedals

These robust steel toe-cap pedals come with adjustable straps that allow you to secure your feet in place in an easy and comfortable way. This is hugely beneficial because you need to be able to have the highest level of comfort imaginable when you are pedaling vigorously, which is essential to the workout. 

Pros and Cons

When making an assessment about any purchase, it is important to weigh up the pros and cons, and it’s no different with the Sunny SF-B1805 Indoor Cycling Bike. We’re happy to report that the positives definitely outweigh the negatives here, and we’re going to look at some of them now.


Robust but super quiet, the SF-B1805 offers the perfect platform for cycling exercise sessions from home. What’s more, we love the price; at a price point between around $600-$800, it’s hugely affordable, and makes a great alternative to other pricier options.

Being able to adjust the intensity of the pedalling is another important factor, and one that will really serve to improve your workout moving forward.

With magnetic resistance against the flywheel you can guarantee a quiet and powerful with very little maintenance.

What I think is a massive seller here is the 44lb weight flywheel. This is a perfect weight that isn’t too hard to create momentum but it offers a smooth, consistent and ‘real road’ feel cycle.

With a multitude of digital additions, and accessories such as a heart monitor, you are able to turn this into a wholly complete workout experience. If you’re looking for the ultimate home workout regime that can help you stay fit over lockdown then this is definitely the bike for you.


Of course, as with any kind of purchase like this, there are some negative elements, and in the interests of balance, we should list these as well. The bike is heavy enough, which can make it difficult to assemble alone, so this is something to keep in mind.

A few users reported some issues with defective parts, but this seems to be a very small percentage, and it does seem as though these parts were replaced as quickly as possible.

Product support and customer service were also cited as weak spots in the experiences people had when buying this bike, and this can be a source of frustration.


As you can see, there is a lot to love about the SF-B1805, and there are a lot of things that play a part in this process moving forward. So you need to try to make sure you come up with ideas that will help you to improve this and make the right decisions.

Try to think about the different ideas and elements you can use to get the best possible workout session from home. Choosing the perfect stationary bike for your home means thinking about what these bikes can offer you, and this is important. Many of them have different features, not to mention an entirely different set of pros and cons.

Try to focus on the benefits of this particular bike, notably the use of magnetic resistance, ideal 44lb flywheel as well as the fact that it is safe, sturdy, well-designed, and easy to use.
