Good post Steve.
Thinks have changed dramatically in bikes in 30 years and the choice is bewildering. Take your time and try loads of bikes. I am 55 and was in the same position as you. Speaking for myself ....and you....
We are never going to be racing boys so you can probably strike a line through that model. You don't want to go off road and so front suspension is not really needed and it is heavy and something else to fix if it goes wrong so maybe you can strike that as well.
There is still loads to choose from. Keep asking loads of questions on here. There are no daft questions, only the ones you don't ask.
