DeerRun vs Wellfit

Two budget brands, two "brushless motor" claims on the brand pages, two Amazon listings that conspicuously omit the word. I have had a motor out of each family and photographed the labels. Neither claim is true, and the way they are untrue is more interesting than the specs.

Two teardowns, two factories, one drive belt

These are not the same company and not the same OEM. The motors come off different lines:

	Wellfit TM037	DeerRun Q2 Urban
Motor label	PERMANENT MAGNET DC MOTORS	PERMANENT MAGNET DC MOTORS
Motor maker	Guangdong Wanrui, model 82-238	Jiang Yin Aotelai, model 75-238
Label date	November 2025	December 2025
Electrical	105V x 6.3A, 4300 RPM	90V x 5.9A, 3200 RPM
Derived CHP	0.75	0.60
Advertised peak	3.0 HP	2.5 HP
Wiring	2-wire, red and black	2-wire, red and black

"Permanent magnet DC" on a two-wire motor is a brushed motor. A brushless motor needs a controller sequencing three or more phase wires plus Hall sensor leads; two wires means physical carbon brushes and a commutator. There is no configuration in which this is ambiguous.

The Wellfit motor photo and the DeerRun one are both archived, as are the brand-page screenshots (Wellfit, DeerRun) making the claim that the hardware refutes. Wellfit's brand page pairs it with a noise figure - "Quiet Brushless Motor, less than 40dB when working" - so the number rests on a premise that is false.

The one thing the two machines do share is a part number. Both run a VEGA X EPJ292 6-rib poly-V drive belt on a 7-groove pulley. Different motor suppliers, same drivetrain part, same claim. That is what an OEM-catalog category looks like from the inside: the "brushless" line is a spec-sheet convention in this price band, not a single manufacturer's lie.

The peak-horsepower number is doing the work

Both listings lead with a peak figure - 3.0 HP and 2.5 HP - measured over seconds. Worked from the labels the continuous figures are 0.75 and 0.60 CHP, ratios of 4.0:1 and 4.17:1. For a walk of twenty minutes, peak is fine. For an eight-hour desk day, continuous is the only figure that predicts whether the motor is still running next year, and neither brand publishes it.

The DeerRun Z10 is the model most people are actually comparing

The Q2 Urban is the pad I opened, but at $240 the Z10 is DeerRun's answer to the TM037 and the one that shows up beside it in carts: 12-level motorized auto incline against the TM037's 5% manual, 300 lb against 320 lb, a 35x16" belt against 36x16".

Its brushless claim is in a weaker position than the Q2 Urban's, not a stronger one. The Z10 uses a physically different motor, so the Q2 Urban teardown does not disprove it - but DeerRun publishes no wattage, no amps and no continuous rating for it anywhere, there is no FCC filing and no manual, and the brand has now been caught making exactly this claim falsely on a sibling. Our spec table labels it "brand marketing claim only" for that reason rather than calling it false.

The Z10's own noise spec is the tell on how carefully these numbers are made: Amazon says 45 dB, DeerRun's own product page says 65 dB. Those are not rounding errors of each other - 65 dB is conversation volume. Amazon reviewers split the same way, some calling it very quiet and others insanely loud.

The wider DeerRun catalog and how it compares to a brand with verified motors is covered on UREVO vs DeerRun.

Support is the tiebreaker, and neither brand wins it

Wellfit holds a BBB F rating, not accredited: 11 complaints, 9 in the last twelve months, 2 unanswered, including a customer who fell during first use. The pattern in them is returns refused and the advertised 30-day trial not honoured, with partial refunds offered on defective units. Trustpilot reads 4.4 across 95 reviews, but one reviewer alleges the company demanded a five-star review in exchange for a refund. It is a Nevada corporation at a Reno registered-agent address, advertises "24/7 customer service" against BBB-listed hours of Mon-Fri 9-3 email-only, and has no FCC filings at all. The TM037 sells on Amazon and the brand site only - no Target, no Walmart, so no independent ratings exist.

DeerRun holds a BBB C- with 73 complaints, 59 of them in the last twelve months, so its trend is worsening rather than improving. It runs at least six brand names out of one factory - DeerRun, SupeRun, SUNELF, RIXY, RACEABLE and LACUFY, per FCC filing 2A8B6-CT05.

The two failure modes differ. Wellfit is small enough that a bad unit becomes an argument with one email address. DeerRun is large enough to answer, and rotates brand names faster than a warranty runs out. Neither is a company you want to need.

What to buy instead

The honest budget answer is to pay for a motor somebody has verified. The UREVO SpaceWalk 5L at around $290 on sale is the cheapest pad whose motor label I have read myself: 735W, S1 continuous duty, 0.99 CHP - a third more sustained power than the TM037's 0.75, from a brand with real FCC filings. It gives up incline range to the Z10 - 9% auto against 12% - so if the climb is what drew you there, the UREVO CyberPad Office pairs 14% auto incline with a verified 0.74 CHP.

If your budget genuinely stops below $200, buy a pad that admits it is brushed rather than one that does not. The 0.60 and 0.75 CHP measured off these two motors are real numbers; it is the label above them that is not.
