Wellfit TM037
The TM037 is a foldable 2-in-1 treadmill/walking pad with front handrails, 320 lb capacity, 0-5% manual incline, and 0.6-6.2 MPH speeds. Features a 3.0HP peak brushed PMDC motor (~0.75 CHP per motor label), 36x16" 5-layer cushioned belt with auto-alignment, 4 control modes (handlebar, remote, app, voice), and 3D VR training routes. 95% pre-assembled, folds flat for vertical storage.
Warranty
Amazon listing claims 3-year frame + 1-year motor/parts. Brand product page says "1-Year Warranty." The effective coverage is 12 months on the motor and parts, the likeliest failure point. BBB complaints show a pattern of refusing returns and not honoring the 30-day trial - multiple customers offered only partial refunds for defective units. Trustpilot reviewer reports motor failure at 5-6 months.
Motor
CONFIRMED BRUSHED - physical teardown (2026-02-18). Motor label reads "PERMANENT MAGNET DC MOTORS" (model 82-238, mfg Guangdong Wanrui Electromechanical Technology Co., Ltd, Nov 2025). Simple 2-wire Red+/Black- connection - brushless requires 3+ phase wires plus Hall sensors. Despite this, brand product page explicitly claims "Quiet Brushless Motor, less than 40dB when working" - a deliberate false technical claim (screenshot evidence, spec & size page). Amazon listing (B0G3W39ZMG) conspicuously omits "brushless." No FCC filings exist for Wellfit at all. "Brushless" is a brand-page-only lie across Wellfit's entire lineup. The WP028 and WP023 pages are now gone - possibly already scrubbed.
Price
Amazon list $205.99, sale $139.98 (checked 2026-04-24). CamelCamelCamel previously showed list $259.99 / 3P sale ~$149.98 since late Dec 2025; sale has drifted lower. Never sold by Amazon directly - always 3rd party, meaning weaker buyer protections. The $259.99 MSRP is likely inflated. Brand site lists $179.99 (sale) / $399.99 (regular).
Stars
Horsepower
Marketing claims 3.0 HP peak. Physical motor label (model 82-238, mfg Guangdong Wanrui) shows 105V × 6.3A = 661.5W input - continuous output ~0.75 CHP. The 4:1 peak-to-continuous ratio is among the worst in the dataset.
Derived from physical motor label (teardown 2026-02-18): 105V × 6.3A × 0.85 efficiency / 746 = 0.75 CHP. Raw electrical input: 661.5W (0.89 HP). Motor: brushed PMDC type 82-238 by Guangdong Wanrui Electromechanical Technology Co., 4300 RPM, Class F insulation, 4.0 kg. Peak HP (3.0) is 4x the continuous rating.
Shock
5-layer cushion belt with anti-shock running surface. No specific 8-point silicone system mentioned (unlike WP028), but Amazon Special Features include "Cushioned Running Belt, Shock Absorbent."
Decibels
Brand product page specs: "Quiet Brushless Motor, less than 40dB when working." The "brushless" part is false (confirmed brushed PMDC via teardown), so the noise claim is also suspect. Brushed motors are inherently noisier than brushless. Manufacturer claim, not independently measured.
Belt
Amazon tech details list "Deck Length: 36 Inches" and "Deck Width: 16 Inches".
Weight
Brand page says 41.66 lbs (consistent with Amazon 41.7). Amazon package weight (35.27 lbs) is less than item weight - likely a data entry error.
App
WELLFIT (free, brand's own app), KINOMAP, Zwift, Apple Health. Also supports AI voice control and 3D VR immersive routes.

Physical Teardown: The Brushless Claim Is False
Motor label (OCR from photo):
- Manufacturer: Guangdong Wanrui Electromechanical Technology Co., Ltd
- Type: PERMANENT MAGNET DC MOTORS (= brushed, NOT brushless)
- Model: 82-238 | Date: November 2025
- Voltage: 105V | Current: 6.3A | Speed: 4300 RPM | Direction: CW
- Insulation Class: F (rated to 155°C) | Weight: 4.0 kg (8.8 lbs)
- Wiring: 2-wire (Red+/Black-) - brushless requires 3+ phase wires + Hall sensors
CHP derivation: 105V × 6.3A × 0.85 / 746 = 0.75 CHP (vs 3.0 HP peak marketing = 4:1 ratio)
Wellfit's "Quiet Brushless Motor" claim is false. The motor manufacturer's own label explicitly identifies it as a permanent magnet DC (brushed) motor. This is not ambiguous marketing - "brushless" is a specific technical term with a precise engineering definition, and the motor physically does not meet it. The false claim appears across Wellfit's entire lineup on their brand site, while all Amazon listings conspicuously omit "brushless."
