Instead of spending 1000$ on a new treadmill. I spent 130$ (shipping was 2/3 of the price) and bought a replacement incline motor to fix my 20 yr old treadmill. Problem solved!!!
It fits. It works. Happy wife.
Affordable working parts
My treadmill incline feature hasn’t worked for years. I replaced the controller board and that solved the problem. This saved me from having to buy a new treadmill!
Love that I found these from this site. It fit my bike nicely. The screw cylinder is a bit smaller but it still fit.
Received the console, hooked it up and i am up and running again, literally. Thanks
Perfect fit great replacement
The board was as promised, a working board. Although, the main issue was probably the power supply, I bought the board for a really good price and now I have the old board for spare parts. Thank you!
After help from a life fitness representative I found the board I needed here and was able to repair my out of commission upright bike. Thank you!
Delivered the correct part right away for a very fair price. Highly satisfied with Hydra Fitness Exchange.
Promptness and excelent service. Spare part as advertised. Fair price.
