What We Like:
- High performance for the price
- OrthoFlex Shockâ„¢ Suspension Systems
- Quick-set controls for speed and incline
- Orthopedic belts on the top models
- Preset workout variety on all units
- Motors and treadmill frames have lifetime warranties
- Music speakers and bottle holders on all models
- Cooling fans on most consoles
- Competitive warranties for parts and labor
What We Don’t Like:
- Lack full-color displays with video or web capability
- Cannot export workout data to mobile fitness apps
Our Verdict:
Since this is a relatively new brand, more time is needed to be certain that 3G Cardio treadmills are as smooth-performing and long-lasting as they appear to be. Still, they do carry impressive warranties to back up the company’s claims of high quality and value. Each of the folding treadmills especially has advantages over similarly-priced competitors. The Elite Runner, however, has plenty of rivals with equivalent performance and more appealing electronics.
