JR2 Frame Construction

Cubii JR2 UnderDesk Elliptical

The Cubii JR2 underdesk elliptical frame is steel-made. However, a set of plastic covers conceals most of it. The steel parts come coated with a rust-resistant black paint finish. The plastic guards are also primarily black, with the pulley covers in neon green or turquoise.

The elliptical trainer rests on a stabilizing bar at the front and a metallic plate at the rear on which the pedal wheels roll. Neither of the stabilizers has any levelers, and the machine does not come with a mat. In addition, it features a unique Attachable ChairLock that prevents a desk chair from rolling away.

This Cubii underdesk elliptical is pretty tiny. However, its footprint is 22.2″L x 11.8″W (56 x 30 cm), so it fits under most regular desks. Also, the pedals reach approximately—10″ (25 cm) above the floor at their highest point. Thus, the desktop should be at least 10″ inches above your knees.

The unit is not too heavy either, weighing approx—18.9 lbs (8.5 kg). Thus, one person can easily carry and assemble the machine. Plus, it has a carrying handle at the top for easy transport.

Resistance system

The Cubii JR2 underdesk elliptical trainer has a mechanical, magnetic resistance system. Therefore, you don’t need to connect it to a power source, and you don’t need a power adapter for it. Unfortunately, on the other hand, it does not adjust the speed or the resistance automatically.

The trainer’s resistance system consists of a magnetic brake integrated into the unit, close to the flywheel, and connected to the tension knob. When you turn the knob clockwise, the magnets move closer to the flywheel and increase the resistance.

Conversely, when you turn the knob to the left, the brake moves away from the internal flywheel, which reduces the pedaling difficulty.

The main advantage of this magnetic brake is that the brake pad does not touch the flywheel. Thus, there is no friction, so the pedaling motion is smooth and quiet. In addition, the brake has virtually no wear-and-tear; you won’t have to bother changing pads like machines with a friction resistance system.

The trainer offers eight levels of resistance. The lowest level generates little resistance, which is excellent for conditioning and recovery training. Although the 8th level provides considerably more resistance, it doesn’t offer extreme difficulty. So, this machine is ideal for light workouts.

JR2 Drive system

The Cubii JR2 underdesk elliptical trainer features durable thermoplastic pedals and a textured surface for improved foot stability. They are pretty significant, approx—14″ (35.5 cm) long and 5.5″ (14 cm) wide. In addition, a set of foot straps for the pedals also comes with the machine.

The pedals connect to the machine’s crankset, with a small set of wheels on their rear section. These are rubberized and have miniature internal ball bearings for smooth motion.

A user weight limit is not specified for this machine because as long as you are seated, it should comfortably support the weight of your legs. The stride length is also not fixed. However, most underdesk ellipticals have a relatively short stride length, approx. 5″ – 6″ (13 – 15 cm), which applies to the JR2 as well.

Like most other fitness machines with a magnetic resistance system, the Cubii JR2 features a belt drivetrain. Therefore, you don’t have to take the unit apart to lubricate its drivetrain. Also, the pedaling motion is smoother and quieter than a chain drivetrain.

Last but not least, this elliptical integrates a small flywheel. Its exact weight is not specified either, but since the machine weighs only 19 lbs, the flywheel probably weighs around 6-8 lbs (2.7 – 3.6 kg).

Fitness monitor

The Cubii JR2 UnderDesk Elliptical comes equipped with a simple fitness monitor. It has an LCD (without a backlight) that divides into two sub-sections. It shows time, calories, strides per minute, and total strides. Unfortunately, it does not have a distance, pulse, or speed reading function.

The monitor only has one button. By repeatedly pressing this button, you can select the workout metric you want to view on display. It also has a scan function; when the scan mode is activated, the display puts the workout metrics in a sequence, showing each for 4 seconds. The button also covers the unit’s reset function. You can press it and hold it to clear all the values to zero.

The fitness monitor is battery-powered, requiring an LR44 battery. In addition, it turns on and begins monitoring your data when pedaling, and it also automatically turns off after a few minutes of inactivity.

Unlike the other Cubii underdesk ellipticals, the JR2 does not have Bluetooth and will not sync automatically with the Cubii mobile app. However, you can manually add your workout data to the app to track your progress.

JR2 Assembly and Maintenance

The main body of the trainer comes pre-assembled. So, all you need to do is connect the pedals, and it’s ready to use. The manual provides all the necessary assembly instructions, and the assembly tools come with the machine.

Maintenance also doesn’t require much. The internal parts do not need any lubrication. So, in terms of care, you only have to keep the unit clean, inspect it for loose or damaged parts, and retighten or replace them as needed.

  1. I appreciate all the detailed reviews and technical specs you share on the machines you review. With that said, I have tried a couple of these under-the-desk exercise machines, and I cannot see the appeal. When I tested them, the motion was not natural (making it difficult to do while you work at your desk), and there didn’t seem to be any health benefit. In addition, the limited range of motion won’t fatigue muscles or raise the heart rate enough to be worth the trouble. It is a newer model, so does this machine provide more benefit than older past models?

    • Hi Aly, thanks for stopping by and sharing your thoughts with us. The two most significant differences between this version and the older version are that it has Bluetooth connectivity and adjustable straps for holding your feet on the pedals. 

      Would you please let me know if I can assist you with any other exercise equipment? I’m always happy to help.

      Kind regards, Robert

  2. What a brilliant idea to have an underdesk elliptical exercise machine. Many people spend so many hours sitting at a desk, so if you can exercise while working away at a desk, you can tone up while you are working. 

    With eight resistance levels, it can cater to different fitness levels. And with a carrying weight of only 8.5 kilos, it is light enough to take to the office. Thank you for introducing me to an underdesk elliptical exercise machine.

  3. Now, this is a product I would use! I was telling someone the other day that sitting (or even standing) at the computer all day is tough on the body because of how long one becomes “frozen in position” for extended periods (relative to how we have evolved to move more regularly). And circulation is also one of the primary things affected.

    Thank you for the insightful review! I’m impressed by the Cubii’s quality and that it’s built to last. I bet if someone chose this piece of equipment, they’d have it for a long time, even with very regular use.

  4. The Cubii JR2 Under Desk Elliptical trainer is easy on your health but high on your list of efficient training machines. Improving mobility and increasing strength is high on my list of desirables. The built-in foot straps add to the product’s charm and feel. The provision of a carrying handle for transporting is genuine, and with its lightweight, it is perfect for the home market, where you might have to move it by yourself. Thank you for a great article.
