I just want to give some words of advice regarding purchasing a new treadmill. I’m familiar with most of the machines out there, but I’ve recently run across other cheap ones people have bought through Amazon that have names I’ve never heard.
When buying a treadmill, check the warranty. Many have parts warranties from 2-5 years, some up to 10, and Landice offers a lifetime warranty (except for the display). Most have a separate warranty for the motor and/or deck. Nordic Track, Proform, Sole, and Horizon usually have a lifetime motor warranty. I’ve helped hundreds of customers get motors under warranty over the years. Peloton, now I know many love the bikes, but the treadmill offers only 1 year on parts, 3 on the motor. Personally, I feel you should be getting a better warranty for the amount of money it costs. It’s also a nightmare to work on. Pay attention to the warranty for parts. Horizon and Sole belts do not last long! I’ve changed a couple with well under 1000 miles on them. I suggest ordering a new belt under warranty before it runs out.
Check the treadmills weight capacity. Many people buy machines that are underpowered. You want more than 2.5hp. Most will come with that or more.
A word about these small $300 treadmills from Amazing mentioned above. I’ve had 3 instances where customers have bought one of these and they didn’t work. When I looked at them, all 3 had metal pieces in the motor preventing it from turning. Many of the ones I’ve seen only measured speed in kilometers per hour. These treadmills weren’t made for running. Another thing is that it is difficult to get parts for them.
So, to recap, check the warranty, horsepower of the motor, weight capacity, and I would stay away from the cheap small treadmills on Amazon.
Best customer service for treadmill companies would be Landice, Life Fitness, and Precor, and Sole.
