Sunny Health & Fitness SF-B1986 Evolution Pro II Cycling Bike Review

The Sunny Health & Fitness SF-B1986 Evolution Pro II Cycling Bike and the Evolution Pro I might look the same at a glance, but in reality, they are different. The former is the upgraded version of the latter, and it has a few interesting additional features.

First off, it has a console that features an LCD monitor with segmented windows. Secondly, the pedals are dual-sided and are designed to accommodate standard gym shoes and special spin shoes. Thirdly, dumbbell holders are included just in case you wish to use a pair while exercising, and finally, there is a large tablet holder for your device.

The Frame and Construction

Sunny Health & Fitness SF-B1986 Evolution Pro II Cycling Bike

The Sunny Health & Fitness SF-B1986 Evolution Pro II Cycling Bike is built with a commercial-grade steel frame that is coated with anti-corrosion paint.

Therefore, it is durable and supports a maximum user weight capacity of 330 lbs./149.6 kg.

For stability purposes, adjustable levelers are integrated into the steel stabilizers. These enable users to adjust the base for superlative stability.

Also, the unit has an overall assembled weight of 136 lbs./61.68 kg that further enhances stability.

Of course, moving a bike of that weight could be difficult. However, transport wheels are attached to the front base for an easy relocation process.

Just for the record, placing the cycling bike on a protective rubber mat could prevent floor damage and sweat spillover. Moreover, it also prevents the bike from sliding when used on certain floor types.

This bike is larger than most average spin bikes. Nevertheless, not large enough to overwhelm your space.

The assembled dimensions are 49’’ long by 24’’ wide by 50.5’’ high. To put it differently, it means the bike needs a workout area with a measurement of 4’ (124.46 cm) length by 2’ (60.96 cm) width by 4.2’ (128.27 cm).

Also, a clearance of 2’ is to be added around it for safety and easy access purposes.

The Seat of the Sunny Health & Fitness SF-B1986 Evolution Pro II Cycling Bike

The Evolution Pro II Cycling Bike has a saddle that is much similar to the Evolution Pro I.

It is generously cushioned (dimensions are 7.75’’ L x 10.5’’ W x 3’’ T) with a groove at the surface. This is meant to provide enduring comfort with air permeability that keeps the butt dry no matter how long you may have been cycling.

That being said, if for any reason you wish to improve the comfort level of the seat, a gel seat cover can be used. Better still, you can have it replaced with any normal bicycle seat of your choice.

The seat is vertically (upward/downward) and horizontally (fore/aft) adjustable. In other words, you can have it adjusted in 4 ways for a perfect fit.

Users that are up to 6’5’’ tall can be accommodated. However, do ascertain that your inseam (measurement of your inner thigh to the ankle) is between 29’’ to 39’’.

The Handlebar

The handlebar has multiple grips that allow you to work out in different postures.

It is coated with thick sponge-like foam for maximum comfort and safety. In other words, you can work out longer and frequently without experiencing slippage or calluses.

Just like the seat, the handlebar is also 4-way adjustable. This solidifies the flexible customization of the bike for users of different sizes and heights.

It is noteworthy to mention that there are heart rate sensors on either side of the grips. These read and transmit your pulse rate data to the monitor for observation when they are grasped during a workout.


As aforementioned, the pedals are dual-sided, self-leveling, and are made of alloy steel and plastic. They are suitable for standard gym shoes and special spin shoes (SPD).

The Q-Factor (the length between the inner left pedal to the right) is not disclosed, but I presumed it should be 122 mm/4.8’’ as the Evolution Pro I.

This is important because your ankle may be stressed if the pedals are further apart than usual. But in this case, it is almost the same as the bicycle.

The Drive

The Sunny Health & Fitness SF-B1986 Evolution Pro II Cycling Bike is belt-driven.

This means the drive system consists of a durable Poly-V belt and other elements such as a 3-piece crankset, durable crank-arms, a pulley, and the 40 lbs./18.14 kg perimeter weighted flywheel.

As a result, the bike’s operation is smooth and quiet. Also, it doesn’t require any periodic lubrication or adjustment, as the case with a chain drive system.

This allows you to train without inconveniencing other people around you. On top of that, you can watch a TV show or listen to music without having to amplify the volume.

The drive is bidirectional. Therefore, it is possible to pedal in reverse if you wish to diversify your workout and tone more muscle groups.

Although, it is not possible to coast as you could on a road bicycle. For this reason, always apply the emergency brake by pushing down the tension knob each time you want to stop pedaling.

The Resistance

The magnetic resistance system of the Sunny Health & Fitness SF-B1986 Evolution Pro II Cycling Bike

This is a magnetic resistance cycling bike. It consists of a magnetic brake pad instead of a felt wool brake pad.

Consequently, the operation of the bike remains smooth and silent even when the resistance is engaged.

The reason for this is because the magnetic brake pad emits magnetic fields on the surface of the flywheel to generate resistance without friction or contact.

Secondly, since there is no friction when resistance is generated, no part wears out, and of course, none will require a replacement.

In other words, the resistance system is absolutely maintenance-free.

The resistance levels are not predefined, meaning it is unlimited.

To increase or decrease it, simply turn the tension knob clockwise or counter-clockwise, respectively.

The resistance system provides a range of workout challenges that are suitable for users of different fitness levels.

The Console

The Sunny Health & Fitness SF-B1986 Evolution Pro II Cycling Bike has a console that features an LCD monitor.

The monitor tracks workout stats such as Time, Target Time, Speed, Average Speed, Max Speed, Distance, Target Distance, Calories Burned, Cadence, Race, and Pulse simultaneously.

It is easy to read but could be compromised if viewed in a poorly-lit environment because it is nonbacklit.

Distance and Speed measurement units can be toggled between miles/mph and km/km/h, and vice versa.

Also, you can set a goal (count-down) for Time, Distance, and Calories.

The console is not Bluetooth-enabled nor telemetric. Therefore, the only way to observe your heart rate is to grasp the HR sensors on the handlebars during a workout. Although, the results are mostly inaccurate.

Nevertheless, dying batteries could cause data not to be displayed accurately. So, always make sure that the 2 AAA batteries are not failing.

If you are concerned about the heart rate data inaccuracy, you may have to opt for an external heart rate monitoring device such as an HR wristwatch.


This bike has a couple of extras that include dumbbell holders that could hold up to 20 lbs./9.07 kg apiece, a tablet holder for entertainment purposes, or viewing different workout videos provided by Sunny Health & Fitness.

There is also a water bottle holder that enables you to keep water handy for hydration during a workout.


The  user rolls the Sunny Health & Fitness SF-B1986 Evolution Pro II Cycling Bike away for storage

The storage of this bike is not complicated because it has front-mounted wheels that help in the relocation process even though it weighs 136 lbs./61.68 kg.

It doesn’t require much space either. A storage area with a measurement of 4’ length by 2’ width will be just fine.
