I wasn't sure what was wrong with my Tectrix BikeMax-R, but I suspected the power supply module. HR grips didn't work. The display was flashing if it came on at all. Sometimes it would work for a 15 minutes then shut off.
I was glad to find the power supply but was a little concerned about the price since I wasn't sure it was the fix. I took a chance and ordered it.
It arrived within days and I'm happy to report it fixed my BikeMax. Had I known it was the fix before I ordered, I wouldn't have been concerned about the price. This bike is out of production and no longer supported. Was very happy to find the part.
I hope I never need a repair part again for this bike, but if I do I will look at Hydra Fitness for the part.
