I have a magnetic exercise (stationary) bike that I use 4 times a week, I've had it for almost 3 years now. The manufacturer is VO2, the model is Apple 66. Now, I'm pretty sure most of you have never heard of the manufacturer or the model but I'm gonna ask anyway, perhaps my problem is universal.
When I pedal, I hear a "grinding" sound coming from the inside of the bike which varies in intensity. I decided to take a look inside and couldn't see a flaw or anything, and attributed the noise to rust so I sprayed a little oil on the wheel. Of course, that didn't help and today I managed to pedal for about 40 minutes before the noise got A LOT worse and the resistance increased dramatically until it reached a point I could not, no matter how hard I tried, move the pedals. It just got stuck.
Unfortunately, I'm in a very sensitive state right now health-wise and I need to keep doing my workouts according to schedule. So, basically, I really need any advice I can get from you all.
Thank you so much.
