Worcester born and bred here (though have lived other places as well).
Would say so far, that rocketdog’s summary is the best. Worcester itself isn’t a wholly exciting place to live (though that can be a blessing too), but it’s pretty safe and relatively middle class. Don’t drive through town at rush hour, as said the traffic is a nightmare! The nightclubs are of particularly low quality, beer boy “shoes and shirt” with cheesy music only variety, and the McDonalds does indeed have bouncers (so do many now) on a Saturday night, but 9 times out of 10 it’s to break up the local girls fighting over something, not the men! 😉
As a place for Mountain biking? It’s a bit of a tease to be quite honest… You’ve got so many good places, a short drive away (and the Malverns in your eyesight!) but there’s not really much you can ride from your door that’s interesting.
As a place for road riding? Worcestershire is Roadie heaven! Some of the quietest, most picturesque roads in the UK, and all within a few miles of Worcester City centre.
Some rules…
Don’t live anywhere in the flood plain… You have been warned!
Don’t live on one side of the river, and work on the other, unless you plan to walk of ride to work every day!
Do revel in the rich historic culture of the City (there’s naff all modern culture sadly!), the Civil War museum, Elgar’s birthplace etc.
Do get a road bike, if you haven’t already! Worcester St Johns club are a reasonably friendly bunch for the most part (though they do place a lot of emphasis on time trialling), and go out 3 times a week in general.
Do head down the Wyre Forest and over the Malverns on your MTB.
If you’ve got any more questions you want answering directly, my email address is in my profile. I live in Worcs, and have done a lot of my life, but I’m pretty unbiased and I know it’s shortcomings all too well.
