Sunny Health & Fitness SF-B0418 Magnetic Mini Exercise Bike Review

The Sunny Health & Fitness magnetic mini exercise bike (SF-B0418) is a super affordable piece of equipment that has plenty of features. Although I tried it briefly it was enough to get a feel of the stability and smoothness of the cycling motion. Needless to say, both are impressive! I comment briefly on the stability below, and you can read about each feature and specifications as you read the rest of the review. This is not a premium piece of equipment, but all in all I was very satisfied with how well it passed the test. The machine seems super durable from what I can tell, and it fits nice within a very affordable price range.

Design of the Sunny Health & Fitness SF-B0148

The Sunny Health & Fitness SF-B0418 magnetic mini exercise bike features a compact and durable design that supports 220 pounds maximum user weight.  Additionally, it weighs only 21lbs and includes a convenient handle which makes moving the device relatively easy. But, its lightness does compromise its stability to a degree, making the unit slide at higher tension levels. I would recommend that you use in on a carpet or a similar surface. Do note, however, that I have purposefully made a series of jerky movements in order to test this unit by trying somewhat unlikely scenarios. But nevertheless, a carpet definitely adds a bit more stability even if you are pedaling like a mad man.


The large non-slip foot/hand pedals will fit all sizes while ensuring a safe and tight grip. The large plastic straps will help your feet and hands remain in place and the small finger grooves on the handles make sure you can comfortably use the Sunny Health & Fitness SF-B0418 Magnetic Mini Exercise Bike for arm pedaling as well. Needless to say, this gives the machine a whole other dimension when compared to other models.

Adjustable resistance

The Sunny Health & Fitness SF-B0418 magnetic mini exercise bike offers 8 levels of tension through a micro tension knob that allows you to switch up the intensity of your workout. So all you have to do in order to use this feature is to just twist the knob and decrease or increase the resistance to keep your workout challenging. You can try interval training by using a tougher level and then switching to an easier ride for a minute or two before returning back to high resistance.

Digital monitor

The digital monitor featured in the Sunny Health & Fitness SF-B0418 magnetic mini exercise bike displays your current speed, time, distance, calories and ODM, including the scan option. However the accuracy will definitely not match your average heart rate monitor, or professional bike measurement screen, so treat these statistics as estimations.

Features to be aware of

The pedal stroke on the Sunny Health & Fitness SF-B0418 magnetic mini exercise bike is too high if you use it under a standard desk. You will need a higher desk to avoid hitting your knees against the bottom, which is a thing I learned the hard way. This is something taller users should particularly take into account.

Other downsides are the occasional knocking sound while pedaling, and the shorter pedal motion compared to traditional bikes. But I believe that a more concentrated motion will yield better results if you are interested in the SF-B0418 for the sake of definition.


If you need a relatively affordable mini magnetic exercise bike, look no further. This little fella is packed with features and will definitely stand the test of time. Although the circular motion is somewhat narrow, it is still one of the best in its class. Highly recommended!
