Sunny Health & Fitness SF-B1423 Belt Drive Review and Comparison

Of course, many of us love cycling. But we cannot always get membership in a gym to use their cycling machine or take a cycle outside. Instead we can choose to buy a cycling machine, which we can use at our home, office or anywhere else. However, it may not always be very easy to choose the correct bike because of a wide variety and thus, a good comparison is necessary.

 Sunny Health & Fitness SF-B1423 Belt Drive

Sunny Health & Fitness SF-B1423 Belt Drive Review and Comparison 1

Buy on Amazon

The SF-B1423 is a product of Sunny Health & Fitness. The handlebars, as well as the seat, are adjustable according to our comfort and ease. The LCD monitor, which is right beside our eyes, displays the time, speed, distance, calories, and scan. You may also adjust the resistance, to increase the difficulty and get better results. The frame is constructed with steel and can hold up to 250lbs of weight. There is a bottle grabber attached as well.

It weighs 40lbs and the belt drive mechanism ensures that the machine works smoothly without making much noise. Overall a good bike, for indoor cycling.

It is important to see how better or worse, it is, as compared with other similar models of Sunny Health & Fitness  so that we can make the best possible choice.

Sunny Health & Fitness SF-B1421 (chain drive)

Buy on Amazon

The SF-B1421 which costs less than the SF-B1423 is not only 10lbs lighter itself but has a stronger structure. It can hold up to 265lbs, which is 15lbs more than the other version. So far, it seems like SF-B1421 is a better version than the SF-B1423. But there is more to it.

We do not have the High density pedaling option in the 1421 version while the less weight can also be dangerous because it will have less grip on the ground. Also, 1423 has another extra feature, which is a belt drive mechanism, which means it’s quieter and smoother than 1421.

Sunny Health & Fitness Pro SF-B901 (Chain drive)

Buy on Amazon

It might seem, that the SF-B901 is no different then the SF-B1423, but that’s not true! Apart from being cheaper than the 1423 version, the B901 also is capable of holding up to 25lbs more of weight!

Both can work equally smooth and quiet, but the B901 does not have an LCD monitor, which allows us to keep a check on our speed, calories, distance, time, and scan.

There are more drawbacks in the B901 version, which includes a hectic task of assembling. Apart from that, the left paddle also needs some adjustments, before you begin using it.

Overall, B901 is a more simple and basic product, which offers fewer features.

Sunny Health & Fitness SF-B901B (Belt Drive)

B901B which seems like an updated version of the B901 differentiates from the SF-B1423 in a few ways. The B901B costs less than the other version, yet it does not have an LCD monitor to display us our progress. It’s equally heavy but can hold up to 25lbs of more weight. Furthermore, the Resistance is touchable and alterable per our preference, making B901B a likable bike too.

On a more mundane level, the B901B has a more stylish and unique handlebar, which we can grip in different ways to increase our own comfort.

There is no bottle holder in B901B, but it has wheels, which make it portable. But we do not have any wheels in the B1423 to make it portable.

Nevertheless, B1423 takes the lead so far!

Sunny Health & Fitness Indoor Cycle Trainer SF-B1002 – 49 lb. Flywheel (Belt Drive)

Sunny Health & Fitness SF-B1423 Belt Drive Review and Comparison 5

Buy on Amazon

The indoor cycle trainer, which costs more than the B1423, is a fine product which differs from the other one in several ways. The indoor trainer has a flywheel 9lbs heavier and is portable at the same time. Feel free to carry it around in your house, gym or workplace!

They both are very similar when it comes to working smoothly, with the belt drive mechanism and changeable resistance, but the indoor cycle again does not have an LCD monitor. On the other hand, the B1423 allows you to keep a check on your progress.


It seems like B1423 is a better product than all of them. It offers a variety of features and is a full-fledged indoor bike. They may all do the basic function and be suitable for everyone, but if anyone is looking for a good cycling bike, which can do most things, B1423 is the correct option.
