Just like everything, you need to have a good quality item.
I have a Kettler racer 9 and it is fantastic, german built, quiet, superb pedal feel and all the data you may want.
You will have to spend £5-600 min to get something decent. I don’t mind paying 2k+ for mine. It’s the best investment you can do for your health. I do 5-7k km a year on it.
Pedaling on a crap indoor bike is horrible.
You need to have a tv with an internet connection.
I am a keen cyclist and train a lot indoors every single day between 20 mins and 2h. I love it.
For training, use GCN spin sessions on youtube, there is one for every level. You will soon get a feel for what is good for you.
When you are not in the mood, you can always watch netflix!
The best way to train on these is fasted first thing in the morning. Like this your system go straight digging in your glycogen/ fat reserves. Instead of the food you have in your stomach.
Lastly, get a handle bar or a weight rack to cross train your upper body. Great for recovery and general body balance.
Lastly you need to have a reasonable (not drastic) food plan and away you go.
I have been doing this kind of stuff for 25 years and if put the effort in and find some enjoyment in the process, your life will change forever and for the better.
HTH.
