Sunny Health & Fitness SF-RBD4703 Convertible Recumbent Bike Review 

The Sunny Health & Fitness SF-RBD4703 Convertible Recumbent Bike is an exercise machine that can be used as a workstation. In other words, you can multitask on it by exercising while doing some tasks on a laptop.  

Interestingly, the desk tray can be adjusted so that you can work on it while standing, and it is removable so that you can exercise with the bike in a traditional foam.  

This bike is designed to enable you to exercise while you work simultaneously instead of doing either separately before or after.  

This bike suits someone who works around the table and hardly has time to exercise.  

However, there is a limit to the work you can accomplish on the desk of this unit.

The Frame & Construction 

Sunny Health & Fitness SF-RBD4703 Convertible Recumbent Bike

This convertible recumbent bike by Sunny Health & Fitness has a solid construction that features a gray-colored steel frame with other parts that are made of quality plastic.  

It has a robust base framework that integrates cylindrical steel stabilizers with adjustable levelers for enhanced stability.  

There are transport wheels at the front base for easy relocation around the room.  

You can walk in and out of the bike without a struggle due to its step-thru design.  

It supports 350 lbs./158.7 kg maximum user weight. This is great when compared to the likes of Exerpeutic 2500 Adjustable Desk Recumbent Bike that only supports 250 lbs./113 kg maximum user weight. However, the latter is way more affordable than the bike on review.  

So, if you are on a budget and your weight is 250 lbs./113 kg or less, you may check out the Exerpeutic 2500 Adjustable Desk Recumbent Bike. 

The assembled dimensions of the Sunny Health & Fitness SF-RBD4703 Convertible Recumbent Bike are 50’’ long by 30’’ wide by 49.5’’ high. Therefore, it requires an area with measurements of 4’16’’ (127 cm) in length by 2’5’’ (76.2 cm) in width for workout activities. Additional clearance of 2’ on each side of it should be considered so that you can exercise with convenience and safety.

The bike weighs 89.3 lbs./40.5 kg after being completely assembled.  

The Seat

The Seat (including the backrest) of the Sunny Health & Fitness SF-RBD4703 Convertible Recumbent Bike is wide, padded, and contoured. The dimensions are 10’’ long by 14.5’’ wide by 2’’ thick. 

Thus, it keeps the back and the butt from pain and soreness that may occur as a result of a prolonged workout.  

The seat is attached to an angled steel base, and it is 2-way adjustable; it can be adjusted horizontally (fore/aft). Therefore, when adjusted the height also increases or decreases by a couple of inches as well. 

Its adjustability makes the bike able to accommodate users that have an inseam (the length of the inner thigh to the ankle) between 26’’ to 35’’.  

That said, the backrest is not independently adjustable.  

There is a patented seat adjustment lever at the side that enables you to quickly and easily adjust the seat without having to get out of the bike.  

No handlebar on the seat as opposed to a conventional recumbent bike seat.

The Desk/Handlebar 

The desk/handlebar of the Sunny Health & Fitness SF-RBD4703 Convertible Recumbent Bike

This unit has a padded 15’’ long by 22’’ wide by 2’’ high desk with a textured surface. This is designed to securely accommodate a laptop, a tablet device, or a book so that you can work or amuse yourself as you exercise on the bike.  

The desk is also detachable; it can be removed when you don’t need it.  

Once the desk is removed, a multi-grip and ergonomically designed handlebar appears, and the bike converts to your regular recumbent bike.  

The handlebar is coated with anti-slip rubber foam that provides firm and comfortable grips needed for a prolonged workout session. 

The desk/handlebar is 2-way, vertically adjustable between 37.5’’ to 41.25’’. Thus, users can even work at the desk while standing.  

The Pedals 

The pedals are balance-weighted, wide, and textured with adjustable safety straps. Therefore, they can accommodate different foot sizes comfortably and securely.  

They are made of solid plastic with a metallic core.  

The Drive 

The Sunny Health & Fitness SF-RBD4703 Convertible Recumbent Bike has a belt drive system. The system comprises a quality belt, a pulley, and a flywheel.  

This is responsible for cycling or motion of the pedals as the user exercises.  

Its operation is smooth, quiet, and even vibration-free.  

Therefore, it will suffice to say that the bike is environmentally friendly because people around you won’t be bothered by your workout activities.  

Furthermore, the drive system is also maintenance-free. As opposed to a chain drive system, it does not require any pre/post lubrication or adjustment.  

Pedaling in reverse is possible because the drive system is bidirectional. That said, resistance does not apply when pedaling in reverse.  

The Resistance 

The resistance adjustment lever of the Sunny Health & Fitness SF-RBD4703 Convertible Recumbent Bike

The Sunny Health & Fitness SF-RBD4703 Convertible Recumbent Bike is equipped with a magnetic resistance system, and there are 8 adjustable levels for diverse workout intensities.  

The magnetic resistance system complements the belt drive system in terms of maintaining the bike’s smooth and quiet operation. In other words, this means that the bike’s smooth and quiet operation remains unchanged even when resistance is engaged during a workout.  

The reason for this is that the resistance system uses magnetic fields and the flywheel to generate resistance without friction.  

So, aside from being complementary to the belt drive system, it is also maintenance-free.  

To increase or decrease the workout difficulty, simply push the resistance adjustment lever upward or downward, respectively.  

The Console 

The console of the Sunny Health & Fitness SF-RBD4703 Convertible Recumbent Bike

The console on this recumbent bike is basic. This means it does not have advanced features such as Bluetooth online connectivity, and built-in workout programs.  

The display is nonbacklit and can only display workout stats rotationally, one at a time after every few seconds by the SCAN function.  

However, you can set it to display a certain workout stat of choice constantly without switching.  

The digital monitor tracks Time, Distance, Speed, Odometer, and Calories. Its clarity is good if viewed in a room or environment that has good lighting, otherwise, it may be difficult to discern.  

There is only a single button on the console which enables you to navigate through the settings. More details on this are included in the owner’s manual.  

The monitor is battery-powered (3 AAA batteries included in the package).  

Accessory 

A tablet holder is built into the console so that a smart device might be kept on it for the purpose of watching workout or entertainment videos while exercising on the bike.  

The desk also has a water bottle holder that is interchangeable. This means, the water bottle holder is detachable and can be attached on either side of the desk as you may prefer it. So, you can keep water handy to maintain proper hydration throughout the workout session without interruption.  

Storage 

The Sunny Health & Fitness SF-RBD4703 Convertible Recumbent Bike can be stored in a storage area with the measurements of 4’16’’ (127 cm) in length by 2’5’’ (76.2 cm) in width.  

It can be easily rolled away via the front-mounted transport wheels.
