The Sunny Health & Fitness Pro is a surprisingly affordable bike that still manages to offer a quite solid design, and- surprisingly- a nicely heavy flywheel. Extremely easy to use, this is the sort of spin bike that is entirely suited to both beginners and more advanced users.

Best of all, while this particular bike does lack some more luxurious amenities, it is still equipped with everything you need to enjoy your spinning class right in the comfort of your very own home without being constantly restricted by the weather.sunny health & fitness pro

Product Features and Comfort

This spin bike boasts of a sturdy design and, despite being light weight compared to other models, it still remains completely stable, no matter how vigorously you pedal. Most importantly, the Sunny Pro is equipped with a- quite heavy for its price- 40 pounds flywheel which enhances its stability. Indeed, numerous studies have shown that the heavier the flywheel, the more efficient your workout, and this also ensures that your pedaling motions remain completely smooth and sleek.

The indoor cycle also features fully adjustable handlebars and seat, so users will be able to customize it to their personal needs, thus greatly reducing the risk of injury. Taller-than-average individuals will have no problem adjusting the seat to their desired height, an option which is not always available with other models. Athletes will also be able to keep the dreaded blisters and sores at bay thanks to the thickly padded handlebars. These, in fact, provide quite a firm grip even when your hands get sweaty. Best of all the handlebars can be horizontally adjusted which once again optimizes your comfort. Now while the seat is lightly padded to enhance your comfort, as is the case with most spinning bikes it still remains quite uncomfortable, though this can be somewhat remedied by adding a gel cover.sunny sf-b901 seat

In true spinning bike fashion, this model is equipped with a pair of exceptionally sturdy pedals, hence allowing you to vary your workouts in terms of sitting or standing up as you cycle away, while keeping your feet well secured. The straps are long enough to fit around various shoe sizes.

About the Company

With a firm commitment to quality, Sunny Health & Fitness is a leading figure in sports gear and equipment. Indeed, most of their products are designed to last for several decades with proper maintenance and care. Because of the quality and popularity of their spinning bikes, we also took the time to review the SF-B1110, SF-B1001, SF-B1203 and SF-B1002 models.

Parts and Assembly

This particular spin bike is extremely easy to assemble, especially since the flywheel and main structure are already joined together. In fact, all users will have to do is join together the bottom support, handlebar, pedals and seat. I personally only needed 20 minutes to unpack and assemble the whole product. The boxed packaging also includes a variety of tools as well as a detailed but simple instructions booklet which is easy enough to understand.


Some customers complained about the slight noises emitted by the spin bike after lengthier workouts on higher resistance settings. While the noise was not loud enough to be overly disturbing, it can hinder anyone who wants to watch a movie while they train.sunny pro handlebars

Overall A Great Spinning Bike

In spite of this drawback, the Sunny SF-B901 does remain a sturdy investment, especially for those that are on a limited budget. In fact, its highly affordable price certainly makes up for the couple of downsides reported. With various tension settings for a wide array of fitness levels, this particular spin bike is designed to help you lose between 300 to 1200 calories per session, depending on your age, gender and weight. The pedals are sturdy enough to allow you to stand up as you work out, hence maximizing fat loss on the upper legs and hips. It may not be equipped with a lot of additional items, but it does provide a challenging and highly effective workout that will help you tone up and lose weight in no time.

The Sunny Pro is protected by a manufacturer’s warranty of 1 year on the frame and 90 days on parts, and can be easily purchased on Amazon.
