sunny-health-ftiness-pro-indoor-cycling-bikeSunny Health & Fitness has been around in the fitness industry for a number of years, and they carry the finest exercise and health equipment from top manufacturers in both Taiwan and China. I have written this Sunny Health & Fitness Pro Indoor Cycling Bike SF-B901 Review as a reference for those interested in this exercise bike.

This is a very popular spin bike, and is built for serious indoor trainings and workouts.

Unlike recumbent bikes, spin bikes provide the rider a more realistic feel to riding an actual bike on the road. Although spin bikes sometime can have fairly comfortable seat, they are however built and

designed for speed and serious workouts than for comfort. So if you are looking for an indoor spin workout, a good spin bike most probably will do the job. The Sunny SF-B901 could be an excellent choice for you. We shall see more details of that in my Sunny Health & Fitness Pro Indoor Cycling Bike SF-B901 Review below.

Resistance Level

Similar to most spin bikes, the Sunny Health Pro SF-B901 uses a friction based resistance mechanism. You can literally adjust the resistance from very minimal to the point where you can’t even move the flywheel. The wide resistance range is awesome, and many people like it. This bike provides lots of flexibilities in terms of resistance levels to cater for different workout intensities.

To adjust the resistance level is also very easy and convenient for the rider. It is all mechanically controlled without any electronics involved. There is a control knob situated right below the handle bar, around the position between your knees when riding. It does not stand in the way at all when your legs are pedalling.

One point to note about this bike is that it comes with a 40 lbs flywheel. Compared to other bikes in the same class and price range, the Sunny SF-B901 has the heaviest flywheel. Together with the chain drive mechanism, the rider will enjoy a much more stable and smoother ride compared to those with a lighter flywheel.

The main purpose of the flywheel in spin bikes is to create a momentum for pedalling. Typically, an 8-lbs or 10-lbs flywheel is sufficient for most casual users. The weighted flywheel is mechanically connected to the pedals. With a flywheel as heavy as 40 lbs, the Sunny SF-B901 bike provides strong inertia to keep the pedals revolving. Hence, the spin bike feels very much like an actual bike on the road. To the user, this is a great pleasure doing work out on the SF-B901 Pro Indoor Cycling Bike.

A very common problem seen among users of this bike is that very often when the resistance is increased, the flywheel will squeal when it spins. The noise could be more obvious for some, while others may not be significant. It is widely believed to be due to the use of cantilevers and pads with dense fabric instead of magnetic resistance. When the resistance knob is turned, the pads press against the flywheel, similar to applying brake pads on a bike. The friction between the flywheel and pads causes the squealing noise.

How to solve this annoying problem? Well, a $5 DuPont Teflon Silicone Lubricant will do the job. Just spray some on the pads (NOT on the flywheel), and your Sunny SF-B901 will be as quiet as before. This solution has been proven to work perfectly by many users.

Display Console

If you are looking for electronics such as a calorie counter, timer, mileage, etc. on the Sunny SF-B901, it will disappoint you. This bike doesn’t come with any display console. Anyway, most spin bikes in the mid-range category do not come with any display console.

A real bike doesn’t have it either. If a computer display console is really needed for monitoring of workout information, than you can consider installing the Cateye CC-ED300 Enduro 8 Function Bicycle Computer.

Comfort Level

According to many reviewers of the Sunny SF-B901 spin bike, it is generally comfortable and very sturdy, much like most of the expensive spin bikes you can find in gyms.

The Sunny SF-B901 is using a chain driven mechanism. Inevitably there will be a small level of noise during the ride. It is after all metal moving over metal. Ensuring the metal chain to be always properly tensioned and oiled will minimize this noise, but you need to accept the fact that the ride can never be totally silent. So if you are thinking of watching TV programs while riding this bike, you may need to turn up the volume a bit. If the slight noise really bothers you, you should seriously consider getting a belt driven type of bike instead, like the Fitness Master X Series Momentum Indoor Cycling Bike.

The main complaint by most reviewers is the uncomfortable seat that comes with the bike. The seat is hard. Maybe the designer of the bike wanted the rider to work harder, and not sitting there on their butt throughout the exercise. Well, depending on your expectations, some said the seat is not an issue to them. But in any case, you can always add on a padded seat cover, like the Mongoose Gel Bicycle Seat Cover, to improve the comfort level. Alternatively, to save some money, you can consider simply putting on a proper bike shorts, and alternate between sitting and climbing during the ride.

Some feedback on the design of the original pedals; the toe straps are tight, but not deep enough. When spinning in a harder gear, it becomes difficult to maintain a cadence at all because the feet cannot stay on the pedals. Depending on the size of your feet, this problem may not be experienced by everybody. However, if it does apply, you can easily replace a set of more fitting pedals. Some suggested wearing proper spin shoes instead. But that is really up to individuals.

Heart Rate Monitor

There is no heart rate monitor on this exercise bike.

But if you really need one to track your heart beat, I suggest wearing a heart rate monitor instead. This is usually more accurate as compared to holding onto an exercise machine’s handlebars that comes with built-in sensors.

Preset Programs

There is no Preset Programs on the Sunny SF-B901 spin bike.

Dimension

This machine supports up to 275 lbs user weight.

It measures 20 x 46.5 x 48.5 inches (W x H x D)

Gross Weight: 108 lbs

Additional Features

The built-in wheels in front of the Sunny SF-B901 bike make it very easy for anyone to move from one place to another. To make sure the bike is resting flat, both the base plates have an easy to turn height adjusters in case you are on an uneven surface.

When the flywheel is turning, the rider is not able coast or pedal backwards. This behaves exactly like a regular bike. Hardcore cyclists like this as it helps with their cadence. Sunny also added a well placed handbrake if there is any emergency to stop the flywheel quickly. Not every spin bike has this emergency brake.

The tension adjustment is very sensitive. With something like less than a quarter turn of the resistance knob, most people will already start to feel the tension.

The design of the bike handles all the rigor of the different positions that you want to ride; standing up, cranking away like you are on a hill to fast sprinting speed, no problem.

Accessories

There is no accessory that comes with the bike.

Pros

The Sunny SF-B901 spin bike is extremely easy to set up. Most people took less than an hour to get everything up and running.

The body of the bike is sturdy, very well-constructed and very stable. Its handle bar and seat is fully adjustable to accommodate as much as possible to its rider’s built. It gives its rider a “gym” quality feel.

Although this machine is not completely quiet when the flywheel is spinning, the noise level is still bearable by most users.

This is a value-for-money indoor exercise bike. It is suitable for both beginner as well seasoned riders. It has the quality and features of more expensive spin bikes.

Cons

The sunny SF-B901 bike does NOT come with clip compatible pedals. Therefore if you really want a good workout, you may have to buy new pedals.

All the adjustments are made with an easy to grab ball; just turn and pull. Some reviewers have feedback that the adjustment holes are too far apart hence fine adjustment is not possible. However, some reviewers found the adjustments to be adequate for their usage.

The Sunny SF-B901 Health & Fitness model is chain driven, while most of the higher end models are belt driven. The main difference is that the chain drive version will be noisier as compared to belt driven ones.

Please also do not forget to occasionally oil the chain to prevent rust.

There is also no water bottle holder. Many users wished to have one.

Consumer Ratings

Out of the over 200 reviews at Amazon, the Sunny SF-B901 bike got a rating of 4. Pretty impressive and many users are really happy with it.
