The Sunny SF-E3914 Elliptical/Stepper Machine combines all the benefits and advantages of a traditional home elliptical machine with a stair stepper’s small footprint and intense workout potential. The 10 inch vertical, 5.5 inches horizontal, and 11.5-inch overall stride length creates a unique climbing motion that maximizes workout efficiency.

The smooth motion of the SF-E3914 puts users in a rhythmic whole body calorie-burning workout. Isolate and target your lower body muscles by cranking up the resistance to focus on your hamstrings, glutes, quads, and more! Engage your upper body for a full-body exercise experience with the upper body motion arms.

The Sunny SF-E3914 Elliptical/Stepper comes equipped with a fitness console that features an LCD that keeps track of time, distance, total distance (ODO), calories burned, speed, pulse, and goals.

SF-E3914 Frame construction

The Sunny SF-E3914 cardio climber features a pretty solid steel tubing frame. It combines oval, cylindrical, and rectangular tubes in its construction, all coated with a corrosion-resistant paint finish, gray.

Of course, the machine also integrates several parts of thermoplastic material. For example, the pedal trays and the covers of the drive system are plastic-made.

Since it’s not a standard elliptical trainer, but a cardio climber, the Sunny SF-E3914 doesn’t take too much space. It is approx. 46.5″ (118 cm) long, and 26″ (66 cm) wide, while the top of its moving arms reaches approx. 62″ (157 cm) above floor level. It is advisable to leave at least two feet of clearance all around the machine to ease access.

The fully assembled trainer is pretty heavy. Its net weight is approx—97 lbs (44 kg). Thus, two persons should carry the packaged unit. However, once assembled, one person can quickly move the machine as its front stabilizer features a set of small wheels.

Also, due to its weight and low center of gravity, the machine provides excellent stability. It doesn’t wobble or move even if the user is close to the maximum weight limit. Plus, both base bars of the machine have adjustable levelers.

Like most elliptical trainers, the Sunny SF-E3914 features two handlebars: one fixed and one mobile. The fixed handlebars are welded directly to the front mast of the machine, so they are non-adjustable. In addition, they integrate metallic pulse sensors, and the fitness console has a pulse reading function. They also have foam sleeves for improved comfort.

The mobile handlebars feature extra-long grips and ball grips at the top. They don’t have pulse sensors, but they also have extra long foam sleeves for an improved grip, and they are attached to the pedal bars and do not lock to remain stationary; they move for as long as you pedal.

Stride, elliptical path, and pedal height

First of all, the Sunny SF-E3914 cardio climber does not have an incline system. Therefore, the length or angle of its elliptical path is not adjustable. Also, since it’s a climber, not a standard elliptical, the pedals’ rail bars are inclined, so the machine provides a ride that resembles climbing a set of stairs.

The machine’s rail bars and pedals are sturdy enough to support users up to a maximum weight limit of 230 lbs (104 kg). The rail bars also have stainless steel covers to protect the paint finish. The pedals come equipped with a set of wheels that allows them to move smoothly on their tracks.

The pedal trays are durable thermoplastic material. They have foam inserts with a textured surface for an improved grip and inner guards. However, they are non-adjustable, and they do not have extra articulations. Instead, they attach directly to the pedal bars via bolts and nuts.

The Sunny SF-E3914 offers approx. 10″ (25.4 cm) of vertical climb, and 5.5″ (14 cm) of horizontal climb leading to an overall stride of approx. 11.5″ (29 cm). Therefore, the machine should be able to comfortability accommodate users up to 6’2″ – 6’3″ (188 – 190 cm).

One last aspect to note here regards the pedal height. At the lowest point, the pedals are approx. 9″ (23 cm) above floor level. Conversely, at their highest position, the pedals are approx. 16″ (41 cm) above floor level. Therefore, it is advisable to use your cardio climber in a room with a ceiling at least 20″ (51 cm) higher than your height.

SF-E3914 Resistance and drive

The Sunny SF-E3914 cardio climber comes equipped with a manual magnetic resistance system. Therefore, you don’t need an adapter for it. On the other hand, the machine does not auto-adjust the resistance, and the included fitness console does not have pre-set programs.

The unit’s resistance consists of a magnetic brake attached to the internal flywheel assembly and the tension knob visible on the machine’s front upright bar. As you turn the knob, the magnetic brake moves closer or farther from the flywheel, which adds or reduces the pedaling difficulty.

This Sunny cardio climber offers eight resistance levels. The first level of resistance doesn’t increase the workout load by a lot. But, conversely, the 8th tension level delivers a considerably more incredible pedaling difficulty if you want to perform a more consistent workout, improve strength, increase stamina, and burn calories.

The machine comes equipped with an 8.8 lbs (4 kg) flywheel featuring a perimeter-weighted structure. This type of flywheel construction improves inertia and adds consistency to the ride. The flywheel is also bi-directional. Therefore, you can pedal in reverse if you want to diversify your workouts.

Like other fitness machines with a magnetic resistance system, this Sunny cardio climber is no different and comes equipped with a belt drivetrain. This type of transmission comes with several advantages. First, it generates less vibration than a chain, so the pedaling motion is very smooth and quiet. And second of all, the belt doesn’t require periodic lubrication.


The SF-E3914 comes with a reasonably simple fitness console without pre-set programs or Bluetooth connectivity. Instead, it features an LCD that tracks time, distance, total distance, calories, speed, and pulse.

It indicates speed and distance in English units (mph and miles), and there are no options for changing them to metric units. Also, the pulse reading function is grip-only. This means that the monitor can only read your pulse if you hold on to the sensors integrated into the machine’s fixed handlebar. It cannot read your pulse from an HR chest strap or other devices.

The fitness console is pretty easy to use. Its Mode button covers its selection function. You can repeatedly press it to scroll through the workout metrics and select the one you want to view. In the same way, you can select the Scan Mode, which rotates all the metrics showing each one for 6 seconds.

The Set button allows you to select goals for time, distance, and calories. After choosing a goal for any metrics, the console will count down from the desired value until zero. And finally, the Reset button clears all the metrics to zero.

The fitness console requires two AAA batteries which come included with the machine. It starts up when you press the Mode button or when it detects pedal movement. It also automatically turns off if it does not see any machine activity for more than four minutes.

The console also integrates a device holder. This consists of a small shelf placed above the unit’s LCD. It is large enough to support any tablet or smartphone. However, the fitness console does not have any connection ports for your device.

SF-E3914 Assembly and Maintenance

The main body of the Sunny Cardio Climber SF-E3914 comes pre-assembled. Therefore, you only need to attach the base bars, the pedal trays, the front mast, the fitness console, and the moving arms.

This may take more than an hour of your time, but the task is relatively simple. The manual provides clear, step-by-step assembly instructions, and all the necessary tools come included with the machine. It is advisable to grease the machine’s joints during the assembly not to develop squeaking noises.

For maintenance, you should keep the machine clean, especially the tracks of the pedals, to prevent any damage to the wheels. If the joints begin to squeak, some lubricant is required. However, the internal parts should not need any lubrication for a very long time.

  1. Hi Robert, this workout stepper machine seems a good choice for me. Since I have a young toddler, it is difficult to find time to go to the gym, so this Sunny Elliptical looks like the perfect solution to lose some pounds and be always in good shape. So, I have a stop at the seller page. The price is reasonable, considering they offer three years of warranty and free shipping for this machine. My question is, Do they offer free shipping in every country or only in the USA? 

    Thank you for your review.


    • Hi Alketa, thanks for stopping by and sharing your thoughts with us. Unfortunately, Sunny only ships free within the USA. Would you please let me know if I can make any other suggestions based on your requirements? I’m here to help.

      Kind regards, Robert

  2. This was a very impressive, informative, and thorough article. I am very much into fitness, and I like elliptical-type machines. My only concern with this one would be since it is more like a step machine, would it be harder on the knees? The only thing I know I don’t like is the fact that there is no online connection.

    • Hi Siobhan, thanks for stopping by. I don’t believe it would be harder on the knees. However, a total elliptical maybe your best option. There are many ellipticals with Bluetooth connectivity; however, there are in a higher price range. Some ellipticals feature fitness apps such as iFit or the new Bowflex JRNY app that even allows you to stream entertainment, such as Netflix. However, these apps require memberships, and the machines are in a much higher price range.

      Kind regards, Robert
