The Frame & Construction 

Sunny Health & Fitness SF-B1805SMART Exercise Bike 

The Sunny Health & Fitness SF-B1805SMART Exercise Bike is built with a durable heavy-duty steel frame, while other protective and cosmetic parts such as the drive-train cover, the console casing, and the stabilizer end caps are made of ABS material.  

It is primarily coated with anti-corrosion grey paint and the seat and handlebar posts and the flywheel have a chrome finish, while the brand name is printed in orange and white colors.  

The bike has a light-commercial construction but it is designed for home use instead. It is rated to support 300 lbs./136 kg maximum user weight capacity.  

The unit does not have stability issues, thanks to the stabilizer bars with adjustable levelers that enable users to level up the bike on a surface that is not entirely even.  

Moreover, its weight (125.7 lbs./57 kg) and the user’s weight further enhance the overall stability. Heavy-weight users won’t feel unstable or experience wobbling during aggressive pedaling.  

The assembled dimensions are 50.8’’ long by 23.4’’ wide by 47.6’’ high. Thus, the bike occupies a workout area with measurements of 4’23’’ (129 cm) in length by 1’95’’ (59.4 cm) in width. On top of that, a 2’ clearance should be added at the rear and on both sides of the unit to maintain safety and easy access. 

The bike can easily be moved around the room by a person through the integrated transport wheels at the front base.  

The Seat of the Sunny Health & Fitness SF-B1805SMART Exercise Bike 

The seat is large and has a design that promotes sustained comfort for a prolonged workout. It is padded and has a median groove for enhanced air breathability.  

The dimensions are 10’’ long by 8’’ wide and has a thick layer of foam that measures about 3’’ high. There are also springs underneath it for movement adaptation during a workout.  

It can easily be managed because the connection system is standard. Hence, it is easy to attach and detach, and if you ever wish to replace it, you won’t have difficulty finding a replacement because alternatives are widely available.  

The seat is 4-way adjustable. In other words, it is vertically (upward/downward), and horizontally (fore/aft) adjustable. Users can adjust it to several inches in both ways to achieve the desired result.   

Because of this, the bike supports 29.9” to 40” inseam heights. By estimation, users between the heights of 5’1’’ to 6’6’’ tall can be accommodated.  

The Handlebar 

The multi-grip handlebar is also 4-way adjustable. There are multiple distinctively marked adjustment positions on the post, especially on the upright post. Thus, allowing you to quickly and precisely make your adjustments as you see fit in seconds.  

The seat and handlebar distance spans between 17’’ minimum to 21’’ maximum when adjusted.  

The handlebar is coated with anti-sweat foam material which enables users to train longer without feeling sore in the palms or slippage. They will also be able to exercise in different workout positions that include off-road riding position, climbing riding position, racing riding position, and aero grip riding position.  

Finally, heart rate sensors are integrated into the handlebar for heart rate monitoring purposes.

Pedals  

The dual-sided pedals of the Sunny Health & Fitness SF-B1805SMART Exercise Bike 

The featured pedals on the Sunny Health & Fitness SF-B1805SMART Exercise are dual-sided. This means they can accommodate standard gym and special spin shoes. One side is toe-caged designed with adjustable safety straps, while the other side is SPD clip designed.  

The pedals are made of metallic alloy and have durable and strong crank-arms and crankset that could support even a 300 lbs./136 kg user to perform stand-up pedaling.  

The Q-Factor (distance between the inner left pedal to the inner right pedal) is 186 mm (7.3’’). This is more than an inch wider than the road bicycle’s Q-Factor. However, the impact on the alignment of the feet to the pedals may not really be felt negatively. 

Just in case you wish to replace the pedals, it is easy because the thread is 9/16’’, which means there are options widely available.   

The Drive 

This is a belt-driven cycling bike that consists of a poly-v belt, a pulley, and a 44 lbs./20 kg perimeter weighted flywheel.  

Its operation is smooth and quiet and that is the reason many users prefer a belt-driven cycling bike over a chain-driven bike. Moreover, no pre or post-lubrication is needed to keep it properly functional.  

The heavy flywheel not only provides consistent momentum but also a realistic riding experience.  

Due to the belt drive system, the bike is environmentally friendly because you can exercise with it in an apartment without constituting a nuisance. People inside and without won’t be bothered by your workout activity.  

The drive system is bidirectional; thus, you can pedal in reverse if you wish to diversify your workout.

However, since it is not possible to coast on the bike, then it is only imperative to apply the emergency brake by pushing down the tension knob whenever you wish to make a sudden stop in pedaling to avoid a potentially injurious accident.  

The Resistance  

The Sunny Health & Fitness SF-B1805SMART Exercise Bike is equipped with a manual magnetic resistance system that provides infinite resistance levels. It means that the resistance levels are not pre-determined, instead, they are micro-adjustable. Simply turn the tension control knob clockwise or counterclockwise to increase or decrease the resistance level.  

The resistance system provides different workout challenges that would be suitable for beginners, intermediaries, and even seasoned athletes.  

The elements that make up the resistance system include magnetic brake pads, the tension control knob, and the high inertia heavy flywheel.  

Resistance is generated without friction occurring because the magnetic brake pads release magnetic fields around the flywheel thereby causing a drag that ultimately results in resistance.  

So, the process of generating resistance is clean, no part wears out, and none shall require replacement.  

The bike does not need to be plugged into a power source since the resistance is manually adjustable.  

The Console  

The handlebar and the console of the Sunny Health & Fitness SF-B1805SMART Exercise Bike 

This bike comes with a modest console that features an LCD monitor which tracks workout stats such as Time, Distance, Speed, Odometer, Calories, and Pulse. The workout statistics are displayed simultaneously with good clarity. 

Nevertheless, when viewed in a poorly lit environment, the readability might be compromised because the monitor does not have a backlight. 

For the heart rate to display, the pulse rate sensors on the handlebar must be grasped during a workout. This is the only way to track the heart rate because the console is not telemetric (not compatible with a wireless HR chest strap).  

The console has a race program that offers workout goals you can select from to target cadence; this shows how fast, or how slow you pedal if the cadence bar is above or below the selected target. It enables you to know when to increase or decrease your pedaling tempo. 

Although, a cadence device needs to be purchased separately if you wish to use the race program.   

The bike is compatible with the SunnyFit app, and Bluetooth-enabled for connectivity. Alternatively, a QR code could be scanned for the installation of the app on your phone. It is free and available for both iOS and Android smartphones.  

This app offers a couple of features that could take your workout experience a step further. It tracks your workout progress in real-time, allows you to train in virtual trails around the world with a real location map, multiple workout videos are available, achieve targeted result with customized workout plans, compete on the leaderboard, and more.  

The console is powered by 2 AAA batteries (included), and the monitor is turned on when the mode button is pressed and it can also automatically turn on/off when you start pedaling or after 4 minutes of inactivity to save the batteries’ power.  

Accessory 

There is a tablet holder integrated to the handlebar, well positioned not to block the view of the monitor when a smartphone/tablet is placed on it.  

A water bottle holder is also attached to the right side of the bike for easy reach or accessibility. This helps you to keep a bottle of water handy for proper maintenance of hydration during a workout session.  

Storage
