Frame and Construction 

Sunny Health & Fitness SF-E3908 Under-Desk/Standing Portable Elliptical Machine

This portable elliptical machine has really got a simple construction that is made up of durable anti-corrosion coated steel frame and ABS-made drive/resistance system shrouds.  

It supports 220 lbs./100 kg maximum user weight capacity.  

The small footprint dimensions are 25.2’’ long by 18’’ wide, while the height is 10.6’’. This means a workout area with measurements of 2’1’’ length by 1’5’’ width should accommodate it. However, you must consider an additional 2’ clearance around it for safety and ease of access.  

The 2-in-1 elliptical trainer has good stability despite its small footprint. This is because it has a rear stabilizer bar with rubber end caps and 2 steel plates (they also serve as the basis for the gliding wheels) at the front base.   

Therefore, you won’t experience instability during workouts. Nevertheless, working out while standing on the machine needs getting used to and requires personal ability to balance.  

Also ensure to set it up on a surface that is even, or one that has a rubberized mat.  

As aforementioned, it is portable and handy, so moving it to and from storage won’t be a problem, thanks to the front-mounted transport wheels, and the handle at the top of it.

In addition to that, it is lightweight with an assembled weight of 25.4 lbs./11.52 kg.  

The Pedals of the Sunny Health & Fitness SF-E3908 Under-Desk/Standing Portable Elliptical Machine 

The pedals are large and textured with protective safety guards. Each of them is attached to a metal platform whose front end integrates a glide wheel while the rear end is attached to the solid cranks.  

The big wheels roll on the steel plate track system providing smooth and quiet glide motion that allows you to experience seamless workouts.  

The pedals’ dimensions are 14’’ long by 5.5’’ wide, hence, most foot sizes can be accommodated without issues.  

As mentioned earlier, the design of the pedals is such that enables you to exercise while standing or seated, and the stride length is 7”.  

The Drive 

The Sunny Health & Fitness SF-E3908 Under-Desk/Standing Portable Elliptical Machine is equipped with a belt drive system that comprises a durable belt, a pulley, a crankset, crank-arms, and a small 3.52 lbs./1.59 kg perimeter weighted flywheel.  

Hence, the pedaling motion is whisper silent and smooth. This means the machine can be used anywhere and any time of the day. It doesn’t interfere when you watch a movie/TV show or listen to music, or when you are in a virtual meeting.  

The drive system is bidirectional. So, you can pedal in reverse if you wish to tone more muscle groups and diversify your workouts.  

It is noteworthy to stress that no maintenance is required as opposed to a chain drive system. However, the only maintenance that might be required of you is to lubricate the pedals’ joints if they start squeaking.  

The Resistance System 

The control knob, pedal, and the console of the Sunny Health & Fitness SF-E3908 Under-Desk/Standing Portable Elliptical Machine

This is a magnetic under-desk mini elliptical machine. In other words, it possesses a manual magnetic resistance system with 8 adjustable levels.  

The resistance system is made up of a flywheel, a magnetic brake pad, and the tension control knob.  

Resistance is generated when the magnetic brake pad releases magnetic fields around the magnetic flywheel. The level of intensity is determined when the tension knob is turned clockwise or counterclockwise.  

In other words, to increase or decrease your workout difficulty, simply select the suitable resistance intensity between the 1-8 resistance levels on the tension knob.  

Apparently, the resistance system’s transmission is frictionless, thus, preventing any internal element from wear and tear that could result in changing a part(s) in the future.  

Moreover, the unit’s operation remains whisper-silent and smooth even when the highest resistance level is applied.  

For those that are wondering if this under-desk elliptical is capable of making them lose weight; yes, it can. However, depending on how much effort you put into your workouts.  

The Console 

As small as the Sunny Health & Fitness SF-E3908 Under-Desk/Standing Portable Elliptical Machine is, it does have a console that features an LCD monitor. It tracks workout stats such as Time, Distance, Speed, and Calories.  

The Distance and Speed stats are measured in miles and mph respectively.  

Since the display screen is small, it has a SCAN function that rotationally shows the workout data one at a time after every few seconds so that you can view all the stats for motivation.  

The LCD monitor is not backlit. Therefore, to be able to see the display clearly while standing or sitting, it has to be viewed in a well-lit environment.   

It is powered by 1 LR44 battery (included), and the elliptical itself doesn’t need to be plugged into a power outlet to function because it’s completely manual.  

Needless to say, the console/monitor is basic. It doesn’t have any additional feature other than to display workout data as aforementioned.  

Storage 

The Under-Desk SF-E3908 Elliptical is storage-friendly because it is compact, lightweight, and handy.  

A space with measurements of 2’1’’ length by 1’5’’ width should suffice for storage; and its height is only 10.6’’.  

So, there are places you can have it stored safely, such as under a desk, or in a corner of the room.  

The built-in handle enables you to easily carry it to a place of your choice within the room or apartment.
