Let customers speak for us
from 1240 reviewsOrdered a part from Hydra Fitness Parts because the OEM part was back ordered for months. Part came in just a couple of days and had it installed by my service tech shortly after. My cross trainer works like new again. Definitely recommend.
Works great perfect fit would buy again
I moved my treadmill from one room to another. I happened to break off a rear foot to it during a difficult spot. It has been like this for 2 years. I decided to look for the part, it was hard to find. But then I found it and jow my treadmill is back together and ready to use
Ordered a part for our treadmill that got lost during a move. Perfect fit! Quick and easy shipping. Would highly recommend if you are looking for odd parts for your Horizon treadmill.
Hydra fit had the part I needed to repair my Bowflex treadmill for only $150. Bowflex techs were telling me I needed a new monitor control for $2,000 but I knew that was wrong because there was no electrical supply to the monitor so it couldn’t be that! Hydrogen gave me a couple ideas I I figured it out. NO thanks Bowflex, and thanks hydro fit.
Used power rods appear to be in good shape and delivery time was very good.
Parts no longer made from my treadmill. Hydra Fitness Exchange had a front roller that works great! Quiet, smooth, almost like new again! Timely shipping, good packaging, helpful website. Thanks!
Product fits perfect. Was able to verify that it would fit my model, and it arrived in a timely fashion. I would order from you guys in the future.
Spirit XE200 elliptical. Common problem of the wheels jumping off and galling the aluminum track rail covers. By the time I fixed the problem, my original track rail covers were too damaged. These were inexpensive and appear to be OEM. Only two bolts to swap them out. Excellent!
Ordered replacement part for my eliptical machine and fit tightly into place and the machine is working fine.
Upon receipt of the item, it would not charge. In working with them I was told to give charging one last shot. This time I pressed the start button multiple times and it started to charge. It synched with my bike. I thanked them for their patience in working out the problem.
The website was easy to use and the product arrived when promised.
We’ve been looking for this part for about 7 years. It fits perfectly. Shipping time was excellent.
Thank you so much!
Product was received on time and fit the description as advertised.
Great value for the price.
