Cubii GO - Under Desk Elliptical Bike Pedal Exerciser, with LCD Fitness Tracker Screen, Adjustable Resistance, Work from Home Fitness, Built-in Wheels and Portable Expanding Handle

This has been one of my most favorite Amazon purchases of 2025 so far! The portability factor was a big selling point for me so I can easily move it from one room to another and don't feel "deterred" by having to lift it around when I wanna use it. I sit around a lot throughout the day and it makes a huge difference when I'm using my Cubii. It's so easy to just mindlessly pedal while you're sitting down relaxing, watching TV, scrolling on your phone or browsing on your laptop. Definitely feels better than not having any movement while you're sitting for hours, helping prevent discomfort and cramps. Operation is very smooth and quiet also!

Very sturdy and easy to use. Not too heavy. My 89 year old mother uses it every day and loves it!

Very convenient

Easy to assemble and the instructions are good. It is heavy, but (as I describe below) the parts (there's a flywheel inside) are heavy and the construction is rigid. That helps it not "wander" in use and contributes to it being quiet. Now - the problem. The right side pedal/disc assembly was loose. As a result, during use, when pedaling, the right pedal would rub against the fixed part of the unit. I reviewed the instructions and I had assembled it correctly. Being rather an "I can fix that" guy, I figured I could fix it. So, out came the tools (note: fortunately, I had metric Allen hex keys). It was not immediately evident how to get to the innards; I wound up removing a lot of screws. But eventually, I was able to remove the bottom for access to the innards. The pedal wheel is mounted to the axle with a crank arm - very similar to a bicycle crank. The problem was that the crank arm was loose on the axle (or spindle to use the bicycle analogy). It is clamped on the square end of the spindle with a clamping mechanism tightened with an Allen screw. I tightened that screw as much as I dared - I did not want to break the screw. So, I removed the arm. I needed a shim between the square part of the axle and the crank arm end that tightens on it. So I made a shim. I cut a piece of a steel can (thankful that the recycling had not yet gone out) and put it between the spindle end and the crank arm clamp. Put the crank arm back on and tightened the clamping bolt. It took a LOT of torque, but I did not break the Allen screw and I could feel that there was no longer any wobble. I reassembled everything (I did put all the screws I got out of each part into separate piles so they would go back in the right place) and tried it out. Works fine - no wobbling or rubbing so it's quiet again. It was like this when I first got it and used it or I would have sent it back for repair. I suspect my messing about inside probably voided the warranty, but I got it working without having to ship it back and wait for a new or repaied one. Amazon might have just exchanged it, but it was fun (well, I call it that) to have a "repair" project to work on. This was clearly a problem on the assembly line. The crank arm was probably not sufficiently tightened.

This is a great way to keep my legs strong. I am in a wheelchair, and can not walk because of brain damage so I try to keep my legs strong for transferring with help. It is quiet and it is easily moved, and takes up little storage space. A Great purchase!!!!!

Sturdy, fits under my computer desk with plenty of knee room to pedal. Easy to use. Love the retractable handle and wheels. Easy to move from one location to another.

I really enjoy the Cubii. I'm moderately active, but I'm a teacher and spend many hours sitting and correcting papers, so I was looking for something to help me to be more active in my daily life. The Cubii isn't challenging for me even at it's highest resistence level, but it increases circulation and helps with joint discomfort. Since I've been using it I don't feel as stiff after sitting for an extended period of time, I recover faster after doing my regular exercises and activities, and my knees (which haven't been the same since a car accident a few years ago) feel stronger and more resilient. The Cubii is relatively compact, quiet, and easy to move from place to place thanks to the wheels and handle extension. It fits nicely under my dining room table and desk. It's not aerobic, but it definitely has had some great health and mobility benefits for me.

Excellent product. I especially like the handle and wheels as i need to move it a lot.

Solid equipment my father in-law is happy using it

I've been using this product for a couple of weeks now and I have to say it's fantastic. If you have a sedentary job (I'm an accountant) this machine is absolutely perfect for keeping the blood flowing and burning some calories. I'd say this is a fantastic alternative to a walking desk, I've tried a walking desk and find it quite hard to type accurately while using one, I'm currently pedaling away on my Cubii while writing this review and having no issues at all. I've lost a couple of pounds over these couple of weeks as well so very happy! I did have a minor issue with my first product where there was a slight knocking sound while pedaling, not that loud and it would have been ignorable for many but as I'm using the product in an office with other people I needed it to be a silent as possible (as advertised). I contacted Cubii who responded in minutes and after sharing a video of the issue with them they immediately sent me out a replacement, the replacement is almost completely silent so I'm sure it's just a one off issue. Great product and great customer service! Cannot fault them at all.

I use it all the time when sitting at my desk using the computer. Without realising it, and after just slow pedaling for a couple of hours it makes a huge difference. After several months now my legs are so strong I feel great. One of the best things I've bought.

Geräuschlos. Klasse.
