RHYTHM FUN Treadmill with Incline, Under Desk

What the research found

The RHYTHM FUN name is a seller label, not a manufacturer with a published product line. At least three physically different machines carry it: a 40 × 15 in, 37 lb walking pad with a 0.5–3.7 MPH range and no incline, a portable machine with 14 incline levels, 7.5 mph and a 350 lb capacity sold in Canada, and the under-desk model with incline this page covers.

Searches for the brand, the model and the specification string turned up no manufacturer page, no manual, no instrumented test, no owner thread and no non-Amazon price. The obvious brand domain, rhythmfun.com, belongs to a DJ and photobooth company in Sioux Falls and has nothing to do with fitness equipment. A Manuals+ category for RHYTHM FUN exists, which suggests a manual for some machine in the line, but it was behind a security check and no manual for this model was found.

The listing describes a 2.5 HP motor, a 300 lb capacity, a 0.5–5 MPH speed range, a 3.5% maximum incline and a 37 × 15 in running area. None of those six values could be confirmed on a non-Amazon page. In this class a 2.5 HP figure is usually a peak claim, and the tested WalkingPad under-desk models are published at brushless and brush motors of 1.0 HP class. A 3.5% incline on a 37 in belt is a small feature: tested walking pads such as the WalkingPad C1 and C2 are listed with no incline at all, so incline is a real differentiator here, but the mechanism is undocumented and the practical benefit at 3.5% is limited.

Safety and belt size

A 5 MPH maximum speed in a 37 × 15 in under-desk frame is at the upper end of what this belt size is normally used for. Treadmill Review Guru notes that shorter belts suit slower running and that some users hit max speed with a tight stride on smaller decks. Walking pads also lack uprights and an elevated console, so users with balance trouble should be careful and a walking pad without a standing desk can be a fall hazard. A machine walked at 5 MPH with a 3.5% incline on a 37 in belt, and no described handrail, deserves that caution more than most.

How it compares with tested walking pads

The closest tested 300 lb under-desk machine is the WalkingPad A1 Pro: 0.5–3.72 mph, 61.73 lbs, a 16.5 × 47 in belt, no incline, a 1-year warranty and an MSRP of $699, scored 75 out of 100 with a build-quality sub-score of 6. The tested WalkingPad line runs from $599 for the C2 to $1,399 for the X25, with the A1 Pro at $699. Against that, the RHYTHM FUN model adds incline and a higher top speed but brings no test data, no published manual and no support channel.

Is it worth it?

This is an unbranded-equipment-style private label with no published test data, so the value rests on price and on a return window, not on a test record. Buy it only if the price sits clearly below a tested, warrantied under-desk treadmill of the same class, and check the machine against the spec sheet on arrival. The 3.5% incline and 5 MPH top speed are the features that could justify a premium over a plain walking pad, but they are only as good as the physical unit matches the listing.

Which model this is

This page covers the RHYTHM FUN under-desk treadmill with a 3.5% incline, listed on Amazon as ASIN B0HHN1CR3S. It is not the brand’s lighter sibling walking pad or the Canadian 14-incline portable model, which are different machines.
