SF-E3911 Frame Construction

Sunny SF-E3911 Cardio Climber

The Sunny  SF-E3911 cardio climber features a steel frame combining oval, rectangular, and cylindrical tubes in its construction for improved sturdiness and aesthetics. In addition, all the steel parts come coated with a corrosion-resistant gray paint finish.

The unit also incorporates several parts of durable thermoplastic material. Some of the most notable ones are the covers of the drive system and the pedal trays.

Since it’s a cardio climber, not a standard elliptical, the Sunny SF-E3911 has a relatively small footprint. It is approximately 42″ (107 cm) long and 23″ (58 cm) wide, while its moving arms reach approximately 60.5″ (154 cm) above the floor level. However, leaving at least two feet of clearance all around the machine is advisable for unhindered usage.

The trainer is not super heavy, weighing approximately 69.3 lbs (31.4 kg). Therefore, two people should carry and assemble the packaged machine. However, one person can move the machine once completed, as its front base stabilizer has transport wheels. In addition, both base stabilizers also have adjustable levelers.

Unlike similar trainers, this Sunny Cardio Climber does not have fixed handlebars, only the two long moving arms connecting to the pedal bars. In addition, they feature extended grips covered by PVC foam sleeves for improved contact. Unfortunately, they do not have HR pulse sensors, and the machine does not have a pulse reading function.

Stride, elliptical path, and pedal height

Since the Sunny SF-E3911 is a cardio climber and not a standard elliptical, it has a relatively short stride of only 9″ (22.8 cm). Also, its elliptical path is almost entirely vertical. Therefore, the vertical climb is approx—7″ (17.7 cm).

Therefore, the machine provides a motion that resembles climbing stairs, offering a workout focusing more on your glutes, calves, and thighs.

Due to the upright angle of the elliptical path, any user between 4’11” and 6’5″ (150 – 196 cm) can use this trainer without a problem. However, the machine only has a maximum user weight limit of 220 lbs (100 kg).

The machine’s pedal trays are made of a durable thermoplastic material and large enough to accommodate footwear of all sizes. They have front guards and a textured surface for improved foot stability. However, they do not have any adjustment features or extra cushioning, but the machine already provides a low-impact workout.

The step-up pedal height (lowest pedal position) is approx—9″ (24 cm). Conversely, the pedals reach approximately 19″ (48 cm) above the floor at the highest point. Therefore, using this machine in a room with an approximately two feet higher ceiling than the tallest user is advisable.

SF-E3911 Drive and resistance

The Sunny Cardio Climber SF-E3911 integrates an 8.8 lbs (4 kg) flywheel, perimeter-weighted for improved inertia. In addition, the flywheel is also bi-directional, which means you can pedal in reverse if you want to diversify your workout. Furthermore, the resistance remains constant, given by the selected tension level when pedaling in reverse.

The machine features a belt drive system. This type of drivetrain comes with several advantages. First, it generates less vibration than a chain, making the pedaling motion smooth and quiet. And second of all, the belt doesn’t require periodic lubrication.

The Sunny SF-E3911 Cardio Climber comes equipped with a manual magnetic resistance system. Therefore, the fitness monitor cannot adjust the resistance automatically and does not have pre-set programs. However, on the other hand, you don’t need a power adapter or an electrical connection.

The trainer’s resistance system involves an internal magnetic brake connecting the tension knob on the upright mast through a steel cable. For example, when turning the knob, the brake moves closer or farther from the flywheel, increasing or decreasing the pedaling difficulty.

There are eight levels of resistance available on this machine. The first resistance level 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 to improve strength and stamina.

Fitness Monitor

The Sunny SF-E3911 cardio climber comes equipped with a pretty standard fitness monitor. It features an LCD that tracks time, distance, total distance, speed, and calories burned. However, it does not have pre-set programs or online connectivity.

Unfortunately, it also does not have a pulse reading function, and the machine does not integrate any pulse sensors. The speed and distance are in Imperial units (MPH and miles). There is no option for setting them to metric units.

Although the fitness monitor does not have pre-set programs, it does have a goal-setting function for a time, distance, and calories. After selecting a goal value for these workout metrics, the monitor will count down from the specified value to zero.

The fitness monitor has three buttons (Mode, Set, and Reset). The Mode button allows you to scroll through the workout metrics and select the one you want to display. This way, you can also set the Scan Mode, which rotates all the metrics showing each one for 6 seconds.

You can select time, distance, and calories for workout targets via the Set button. And finally, the Reset button clears all the values to zero except the odometer (total distance).

The monitor is battery-powered, requiring two AAA batteries that come with the machine. In addition, it starts recording your workout data when you pedal and automatically turns off after four minutes of inactivity on the machine. All the data clears to zero when it enters sleep mode except the odometer.

SF-E3911 Assembly and Maintenance

The machine’s drive and resistance unit come pre-assembled. However, you will still have to attach the console mast, the pedal bars, the pedal trays, the two base stabilizers, the moving arms, and the fitness monitor.

Consequently, it may take more than an hour of your time, but the task is not too difficult. Also, the manual provides clear assembly instructions and schematics, and all the necessary tools come with the machine.

For maintenance, the internal parts do not require any lubrication. So, you only have to keep the machine clean, especially the pedal tracks, to prevent any damage to the pedal wheels. It’s also necessary to periodically inspect your climber to ensure that all the parts still hold tight in their places and still function correctly.

  1. This looks like a great exercise machine. I love the idea of working my arms and doing steps at the same time. It seems much more user-friendly than just exercise bikes, as you are standing upright. I liked the feature where you can put your device above the digital monitor to see it all clearly as you work out. And there are even videos you can watch and work out with for the Sunny machine—all in all, an excellent buy.

  3. I need a machine to work out at home, and so far, my two options are a rowing machine and a climber. However, I used to do both at the gym. What would you recommend?

    Based on your review, it looks like this climber is essential and will perfectly do the trick. I don’t need anything too expensive or sophisticated.

    I will bookmark this for future reference and hope to make a decision soon. Thanks for sharing.

    • Hi Enrique, thanks for stopping by. A stepper or rowing machine are both excellent choices, but I would pick a rowing machine if I had to choose for myself.

      Kind regards, Robert

  4. I love how this climber doesn’t take much space from a room. It feels compact yet strong on a person’s body. I’m pretty sure this climber would fit perfectly in my room; that way, I can have a peaceful workout routine without having to deal with my social anxiety about who might be watching me work out. I’m so glad I came across this review, and how well explained everything is!
