Sunny Health & Fitness SF-E3912SMART Elliptical Trainer Review 

The Sunny Health & Fitness SF-E3912SMART Elliptical Trainer has Bluetooth connectivity that allows you to connect to SunnyFit app so that you can stride along with the Sunny Health & Fitness experts, track your workout progress in real-time, and more.  

It is important to understand that this is the upgraded version of the classic version that does not have the SunnyFit app connectivity.  

The unit needs to be plugged in for the resistance system to work properly. However, it can be used manually without having to plug it in, but the resistance level will be stuck on the last setting used.

The Frame & Construction 

Sunny Health & Fitness SF-E3912SMART Elliptical Trainer

The Sunny Health & Fitness SF-E3912SMART Elliptical Trainer is a full-body and low-impact cardiovascular machine designed for home use. It’s made up of two major components, and that would be steel and quality plastic.  

The frame is made of steel while the bodily (protective and cosmetic) parts such as the drive & front base covers, the pedals, and the console covers are made of ABS material. 

It is sturdy enough to support up to 330 lbs./150 kg maximum user weight capacity.   

This elliptical trainer is bigger than the entry-level elliptical trainers such as the THERUN Elliptical Machine. Nevertheless, it won’t overwhelm your space either. The assembled dimensions are 57’’ long by 20.4’’ wide by 63.8’’ high.  

In other words, it would require a workout area with measurements of 4’75’’ (144.78 cm) length by 1’7’’ (51.81 cm) and it will also need additional clearance of 2’ all around it for safety and convenience reasons. 

It is recommended that the unit should be used in a room with a minimum of 8’ ceiling height. Although this also depends on your height, but 8’ would be safe for most people.  

The base is floor-friendly due to the rubber pads underneath the front and rear stabilizers, and there are adjustable levelers at the rear which enable users to level up the machine on a platform that may be crooked for improved stability.  

The integrated transport wheels at the front base facilitate the relocation of the unit around the room easily. The elliptical trainer only weighs about 104.8 lbs./47.5 kg.  

The Pedals of the Sunny Health & Fitness SF-E3912SMART Elliptical Trainer 

The machine has non-slip pedals that are large enough to accommodate different foot sizes securely and comfortably. As aforementioned, they are made of quality plastic and each of them is attached to a steel bar that is connected to the drive and to the dual-action handlebars.  

The stride length is 15.5’’, which is not so bad for an elliptical machine of this category. Users up to 6’5’’ will find it comfortable. However, some users have a different opinion regards to this though.  

The distance between the ground and the pedal at its highest level is 16.5’’ and the step-up height is 6.9’’. 

The handlebar 

The handlebars of the Sunny Health & Fitness SF-E3912SMART Elliptical Trainer

The Sunny Health & Fitness SF-E3912SMART Elliptical Trainer has 2 sets of handlebars.  

One set is static, and it’s located and attached to the console mask, and they have EKG sensors integrated into them. This means the static handlebars are not moveable or adjustable. They provide support and stability when you do not wish to engage the upper body in exercise. 

Whenever they are grasped during a workout, your heart rate data is transmitted and displayed on the monitor.  

While on the other hand, the dual-action handlebars are attached to the console mast and then connected to the pedals and the drive. As a result, they always swing back and forth as long as the pedals are being used because the connection is fixed.  

The dual-action pedals allow you to engage the upper body in exercise so that you will experience full-body workouts.  

They don’t have heart rate sensors integrated onto them, and they are not adjustable either.  

Both sets of handlebars are generously coated with soft rubber foam for comfort and to prevent slippage. 

The Drive 

The SF-E3912SMART Elliptical Trainer is a belt-driven machine. This means that the drive system consists of a durable anti-stretch belt, a pulley, and a 15.4 lbs./7 kg high inertia flywheel.  

Having a belt drive system gives it two distinct advantages over chain-driven elliptical trainers.  

First of all, its operation is smooth and quiet, and even stable because of the heavy flywheel. Therefore, users that are concerned that a sleeping baby may be awakened while working out won’t have to worry because its sound level is completely tolerable.   

Watch TV shows or listen to your favorite music without noise interference.  

Second of all, no maintenance is required. No taking parts apart are needed, and no pre or post-lubrication is required.  

The drive is bidirectional. Differently put, you can pedal in reverse if you so wish. However, the manufacturer does not recommend that you pedal in reverse because this may loosen the pedals and strip the crank arms.  

The Resistance 

This elliptical trainer is equipped with a motorized magnetic resistance system with 16 adjustable levels. The resistance system consists of a small servo motor, a magnet, and a flywheel.  

Therefore, the unit needs to be plugged into a power outlet in order for the resistance system to be operational.  

Resistance is created by the magnetic fields generated around the flywheel by the magnetic pad. Therefore, friction is totally out of the equation for generating resistance. Thus, the quiet and smooth operation of the unit is not altered even when resistance is engaged at whatever level.  

It is also maintenance-free. No adjustment or part replacement is needed. After all, no friction occurs and no part wears out in the process of generating resistance.  

The resistance adjustment buttons are on the console. Simply push the Up button to increase the resistance or the Down button to decrease it. Challenge yourself with the 16 resistance levels that provide easy to difficult intensity workouts.  

The Console  

The console of the Sunny Health & Fitness SF-E3912SMART Elliptical Trainer

The Sunny Health & Fitness SF-E3912SMART Elliptical Trainer has an average console that features an LED monitor, Recovery button, Resistance buttons, Mode button, Start/Stop button, and Enter button.  

There are also 24 mode programs available that include Manual, Pre-program, Watt, Body Fat, Heart Rate, and User programs,  

The monitor tracks and displays workout stats such as Time, Distance, Speed, RPM, Odometer, Level, Program, Heart Rate, Target Heart Rate, and Watt. These are displayed simultaneously and are crystal clear. 

The default speed and distance units are in mph and miles, respectively.  

You will be able to connect your device with the unit via Bluetooth. This means you can download the SunnyFit app for free from the app stores. It is available for both Android and Apple smartphones.  

The SunnyFit app allows you to track your workout progress in real-time via your smartphone, explore the world virtually with a real location map, connect and share your journey with the Sunny community, and more.  

Accessory 

There are tablet and water bottle holders available on the unit. 

The tablet holder is on the console and it can accommodate most devices.  

While the water bottle holder is attached to the console mast. This helps you to keep water within reach during workouts in order to maintain proper hydration.
