We have not tested any of these machines and we make no claim that any of them is suitable for any person, any condition or any purpose. This is a comparison of published specifications, published warranty terms and the public recall record, nothing more. We picked the models by one rule: seated under-desk ellipticals sold widely in the US whose maker has a product page we could open, with each brand name checked against the CPSC recall database on September 25, 2026.
Almost every listing in this category is aimed at older shoppers and almost none of it is written in numbers. That is the problem worth solving before buying, because two machines that look identical in a photograph can differ by four inches of height, which decides whether the thing fits under your desk at all.

One maker prints a full engineering table, another prints only a resistance count
Sunny Health and Fitness publishes product dimensions, product weight, pedal step height, stride length, flywheel weight, pedal size and warranty terms for its SF-E3872, while the Cubii product pages we opened on September 25, 2026 publish a resistance level count and nothing else, and neither maker publishes a maximum user weight.

What these spec sheets actually contain
Sunny Health and Fitness prints an engineering table for the SF-E3872 and it is the most complete one we found in the category: product dimensions of 24 by 19 by 11 inches, a product weight of 25 pounds, a 7-inch stride, pedal step height from 3.46 to 7.4 inches, 8 levels of belt-drive magnetic resistance, a 3.52-pound flywheel, foot pedals of 13 and seven-eighths inches by 5 and one-eighth, non-slip textured pedals, a carry handle, floor stabilizers and a digital monitor.
The same page carries a second weight: its description says 24.2 pounds while the specification table says 25. Read the table rather than the paragraph, and expect the two to disagree.
Cubii is the better-known name here and publishes far less. On the pages we opened on September 25, 2026, the Move page states six levels of resistance, the Go page ten and the Total Body page twelve. We found no dimensions, no product weight, no stride length, no user weight limit and no warranty terms on those pages, and the manuals hub offers language choices rather than a downloadable specification.
In this category the spec table is itself a differentiator, because half the makers do not print one.
The number nobody publishes: maximum user weight
On a treadmill, maximum rated user weight is the headline specification and every maker prints it. On a seated under-desk elliptical neither maker above publishes one, and the reasoning offered in the category is that the user sits in their own chair rather than standing on the machine.
That is plausible and it is still a gap. The pedals, the crank and the frame carry load, and without a published figure there is nothing to compare and nothing to cite if something bends.
The specifications that do exist are worth using. Product weight decides whether you can move the machine between rooms, and 25 pounds with a centered carry handle is a very different object from a 50-pound one. Sunny also states that the magnetic brake means no friction-generated noise and no wear parts to replace.
Fit under the desk is arithmetic, not a review
No published rule we could open sets how much room a desk must leave underneath, and no maker of these machines states a clearance its product needs. That half of the sum is a measurement you take yourself, with the desktop at the height you actually work at.
The makers supply the other half. The SF-E3872 stands 11 inches tall and its pedals rise to a maximum step height of 7.4 inches, so the machine needs 11 inches of floor-to-desktop space before a knee enters the calculation. Set those two figures against what your own tape measure says and the answer is arithmetic, not a review.
Two more dimensions decide comfort. Stride length, 7 inches on the Sunny, sets how far the foot travels; the pedal itself, nearly 14 inches long, sets how freely you can place it. A machine that publishes neither cannot be compared on either.
Measure the clearance under your own desk first, then shop only machines that publish a height.
What the recall database shows for ellipticals
We searched the CPSC recall database on September 25, 2026 for Cubii, DeskCycle and Sunny Health and Fitness and found no notices for any of them. The elliptical recalls on file describe full-size machines: Nautilus recalled about 10,000 Schwinn 460 ellipticals on December 6, 2011 after nine reports of foot plates detaching or breaking during use, and Octane Fitness, Johnson Health Tech and Stamina Products have other notices of the same kind, each of them a foot pedal or foot plate letting go.
That record points at one component, the interface between foot and machine, which is under repeated load on any elliptical and is the part a buyer can inspect. Published details that speak to it — pedal dimensions, non-slip surfaces, floor stabilizers — are worth more than a photograph of someone smiling at a laptop.
The warranty tells you what the maker will stand behind. Sunny publishes one year on the structural frame and 180 days on other parts and components. That is short by the standards of desks and treadmills, and it is at least written down.
What to check before you buy
Buy from the maker that publishes numbers. In a category with no independent test method and, in half the cases, no spec table at all, a willingness to print dimensions and warranty terms is the most useful signal available.
Wait if the machine has to fit a specific desk and its height is not published. Eleven inches of machine and a 7.4-inch pedal rise need room that a low desk may not have, and returning a 25-pound box is a bad end to the exercise.
- Overall height in inches, checked against the clearance under your own desk
- Pedal step height, minimum and maximum, if the maker publishes it
- Stride length and pedal dimensions, which decide foot placement
- Product weight, since you will move it, and whether a carry handle is fitted
- Warranty terms in writing, separated into frame and parts
What to watch next
- Whether any maker starts publishing a maximum user weight for a seated under-desk elliptical, which would make the category comparable
- The CPSC recall database for the first notice naming a seated under-desk machine rather than a full-size one
- Whether Cubii adds a specification table to its product pages, since its competitors publish one and it does not

Seated under-desk elliptical
Where to look: Amazon
The mainstream version. Choose it on the numbers in the table rather than the copy above it, and check the height before anything else.
- Magnetic resistance has no friction wear parts
- Dimensions and stride are usually printed
- No maker publishes a user weight limit
- Warranty terms are short in this class
Under-desk pedal exerciser
Where to look: Amazon
A simpler mechanism for a desk with little room underneath. Its weakness is documentation, so shortlist only the ones that publish a height and a weight.
- Lower overall height than most ellipticals
- Light enough to move one-handed
- Shorter pedal travel
- Specs are often missing entirely
Under-desk elliptical with display
Where to look: Amazon
Useful if you want a record without an app. The distance and time figures are the honest ones; treat the calorie number as a rough index.
- Prints speed, time and distance without a phone
- Scan mode cycles the readings
- Calorie readouts are unverifiable estimates
- Battery type is rarely published

Questions readers ask
How tall is an under-desk elliptical, and will it fit?
The one complete spec table we found, for the Sunny SF-E3872, gives 24 by 19 by 11 inches with a pedal step height from 3.46 to 7.4 inches. No maker in this category publishes a required desk clearance, so the fit depends on a measurement you take under your own desktop.
What is the weight limit on an under-desk elliptical?
Neither Sunny Health and Fitness nor Cubii publishes a maximum user weight on the product pages we opened on September 25, 2026. These are seated machines, but the practical result is that no figure exists to compare or rely on.
Have under-desk ellipticals been recalled?
Not as of September 25, 2026. We searched the CPSC recall database that day for Cubii, DeskCycle and Sunny Health and Fitness and found no notices. Full-size ellipticals have been recalled, including about 10,000 Schwinn 460 machines in December 2011 after nine reports of foot plates detaching.
What does the resistance level number mean?
It is a count of settings on that machine only, not a scale shared across brands. Sunny publishes 8 levels of belt-drive magnetic resistance on the SF-E3872; Cubii publishes 6 on the Move, 10 on the Go and 12 on the Total Body. A 12-level machine is not necessarily harder than an 8-level one.
