SF-E3919 Frame construction
The Sunny SF-E3919 Cardio Climber frame is steel tubing, but the flywheel covers and the other drive and resistance elements are ABS-made. In addition, all the steel parts in its construction feature a durable black paint finish, resistant to chipping and corrosion.
The unit’s main chassis is a one-piece element with the rail system directly welded to the frame. Thus, it considerably improves the overall sturdiness of the machine. Also, the two rail bars have stainless steel covers for extra protection. However, the console mast and the two base bars attach to the mainframe via bolts and screws.
Like most other steppers, the Sunny SF-E3919 has a pretty small footprint. It is only 44″ (112 cm) long and 25″ (63 cm) wide. Therefore, it can fit well even into a small room. Furthermore, leaving at least two feet of clearance all around the unit is advisable.
The fully assembled unit is relatively heavy. It weighs approx. 95 lbs (43 kg), so it is recommended that two persons carry the boxed machine. However, its relocation is accessible once assembled using its two front wheels. Also, its rear base bar integrates adjustable levelers so you can correctly stabilize the unit on any floor.
This Sunny elliptical machine features two sets of handlebars; one is stationary, and the other is mobile. The fixed handlebars attach directly to the console mast. They have small, standard grips and integrate EKG sensors.
The moving arms feature extended rubberized grips with ball grips at the top. They attach both to the main upright bar and the pedal bars, so they continue to move for as long as you are pedaling.
Elliptical path, stride, and step-up height
Since it’s a climber or an elliptical stepper, the Sunny SF-E3919 cardio climber features an almost entirely vertical elliptical path.
The two rail bars of the pedals have an angle of approx. 45°, so the pedaling motion resembles the one of an elliptical trainer with an incline. However, the machine does not have an automatic or manual incline system; the two pedal rail bars are stationary.
The unit’s pedals are a durable ABS material. They have a non-slip surface and inner guards for improved foot stability. However, they don’t have extra cushioning or articulations and attach directly to their bars via two screws. Nevertheless, they’re durable enough to support users up to 260 lbs (118 kg).
Since it’s an elliptical stepper, the Sunny SF-3919 doesn’t have a long stride. It offers a horizontal range of motion of only 7″ (~18 cm), pretty much characteristic of steppers. Nonetheless, due to the handlebar configuration, and the specific construction of the frame, it can provide high-intensity workouts with maximum stability.
The lowest pedal height (or step-up height) is approx. 10″ (25 cm), while the highest pedal point is approx. 16″ (40 cm) above floor level. Using the machine in a room with a ceiling at least 20″ (51 cm) higher than your height is advisable.
SF-E3919 Drive and resistance
The Sunny SF-E3919 Cardio Climber features a manual magnetic resistance system. Therefore, it doesn’t require an external power source or an adapter. Also, its console cannot automatically control the resistance and does not have preset workout programs.
The machine’s resistance system consists of a magnetic brake connected to the tension knob on the unit’s main upright bar via a steel cable. As you turn the knob clockwise, the brake moves closer to the flywheel, increasing the pedaling motion load.
Like many other fitness machines with a manual magnetic resistance system, the Sunny SF-E3919 offers eight tension levels. The first level delivers little resistance, which is great for recovery training. Conversely, the 8th level of resistance provides considerably more pedal tension, allowing the possibility of performing a more intense workout and improving strength and stamina.
The unit’s internal flywheel is not as heavy as a spin bike but weighs 14 lbs (6.3 kg), which is not bad for a home-use machine. It is perimeter-weighted for added inertia. It is also bi-directional.
Therefore, you can pedal in reverse to diversify your workouts. But, of course, when pedaling in reverse, the machine delivers the same resistance as pedaling forward.
This elliptical stepper comes equipped with a belt drive system. This type of transmission comes with several advantages. First, you don’t have to worry about taking the central unit apart for internal lubrication.
Second of all, the pedaling motion is tranquil, almost entirely silent. And finally, a belt drive produces less vibration than a chain drive, which results in a smoother pedaling motion.
The Sunny SF-E3919 has a mid-range fitness monitor without any workout programs or online connectivity but offers plenty of features to keep you motivated.
The fitness monitor comes equipped with an LCD divided into multiple sub-sections. It tracks time, distance, speed, RPM, calories, and pulse. Each of these metrics has a separate window, except for speed and RPM, which share the same window; each remains on screen for 6 seconds.
The top, the larger display, can show any selected workout metrics. You can choose the unit’s Scan Mode, and they will rotate in a sequence of 6 seconds. In addition, the top display shows the current date, clock, and room temperature when the monitor is idle.
The speed and distance are shown in MPH and miles, while the temperature is Fahrenheit. There is no option for metric units. Also, the monitor is not telemetric. Unfortunately, it cannot track your pulse through a wireless HR chest strap. If you want to monitor your heart rate during your workout, you need integrated sensors.
Although the fitness monitor has no preset programs, it offers goal settings for time, distance, calories, and pulse. So, when setting a target goal for any workout metrics, the monitor will show the remaining amount until you reach your goal. Likewise, when you achieve the selected pulse rate, the monitor will beep for a heart rate goal.
The monitor also has a Recovery function and a BMI function. The Recovery function gives you a fitness rating at the end of your workout based on the time it takes your heart to return to an average BPM.
The score is between F1 – excellent and F6 – poor. Next, the BMI function requires you to input your data, such as age, weight, height, and gender. Based on this, the monitor will calculate your body fat percentage.
Two other notable monitor functions are the tablet holder and the HRC sticker. The tablet holder is above the LCD, so a tablet on it won’t cover your workout stats. Unfortunately, the monitor has no docking ports for your phone or tablet.
The HRC sticker is placed at the top section of the monitor and shows the heart rate zones you should aim for depending on your age to benefit from a better aerobic output, fat burn, etc. Not all ellipticals have this feature; this HRC grid is usually in their manual, so you may not have it all the time when you exercise.
SF-E3919 Assembly and Maintenance
The base frame of the machine comes pre-assembled; this also stands for its drive and resistance elements. However, the two base bars, the monitor mast, the pedals, the handlebars, and the fitness monitor still require assembly.
Consequently, the task is not too complicated; the manual provides clear assembly instructions and schematics, but it can take two hours. Also, all the necessary tools for the assembly come with the machine.
Once fully assembled, you don’t have to worry too much about maintenance. The internal parts don’t require any lubrication. So, it’s advisable to keep the unit clean, especially the rails, and lubricate the joints if necessary.
