One of the best treadmill in the market at this price. Its been more than a year that i bought this machine online. I haven’t face a single issue yet. Its really a fun working out with CT5.2 Treadmill. Different workout programs, with different workout resistance offers you the liberty to choose a program according to your requirement and capacity. Worth investing

@Ed just the customer support executive they will surely help you out….. if not just contact your near by service center. Donot go for any local technician…. or you may lose the warranty.

Its an average treadmill. For the first 1 year faced no issues but from last week, the belt was slipping like any thing. Got the belt changed from a technician. Hope now its works fine.

Its price does not justify its functionality. Research well before you buy, look for some other brands, of the same range and compare with the other products and make a decision. Life fitness and key fitness treadmills are some other options

We have a Horizon CT5.2 treadmill, and lately, when my wife is using it at a moderate speed (2.5 mph), the treadmill stops after 17-19 minutes , and gives her an “E1” error. It doesn’t happen every time though; sometimes, she can finish a 30-minute workout. It’s very irritating to have the treadmill just quit during the workout.

I can’t find any reference to this error in the manual.

Can you explain how to avoid getting this error?

I have a Horizon CT5.2 Treadmill and it is stopping when it gets to 15-17 mins while walking. It shows E1 error. Like the other reporting which is not shown in the manual. Could you share hot to fix this so everyone is not writing to you about the same error message?
Can you explain how to fix avoid having the treadmill stop during work out?

Our CT5.2 treadmill suddenly stopped working.
We turn on the small switch at the bottom and a red light turns on and closes immediately. No more current is flowing to the control panel. Is it possible to get technical support?
