It's also a really good motivator, if you loose say 5 kg you will notice the difference every time you get on the bike, which will encourage you to lose more, you notice the effect far more than just looking at the scales. I struggle with weight, I find it easier to lose it than to keep it off, the hardest part is the commitment that it's what you'e going to do, a regular bike ride does help with that routine.
I had a quick google for secondhand bike businesses in Birmingham, there's a few though I have no experience with any of them. IMO, you don't need to spend a grand on a bike for what you want, get yourself a decent hybrid or rigid MTB, make sure it has appropriate gears and tyres and just get riding. If you find it's for you, treat yourself to a top notch bike when you reach that goal. By then you'll have a good idea of what you want, or if you're really lucky that you don't need anymore than you already have (OK - that's never happened)
When things get back to normal you could also start looking at local groups to ride with, they're not all racing clubs and from what I know of Birmingham there's plenty of choice.
Good luck, both with the bike hunting and the weight loss.
