I did a lot of cycling until about fifteen years ago. I’d like to get back into it, so I’m going to have to start the shopping experience. I’ve been reading here and elsewhere – I really appreciate all the advice here.

But I haven’t been on a bike in years! Any ideas on how to make sense of this “cold”? Do bike shops let you ride for very long? When do they do the sizing thing? Do they sort of just look at you and guess on which bikes to recommend? I figure the first day of this will feel awkward and not very satisfying. When I was a kid I just always had a bike.

I go to a gym regularly, and I'm reasonably in shape, for what it's worth.

I know it’s.... just like riding a bicycle.
Someone had to say it
But I do appreciate any advice.
