Hi, James:
I remember having rented a car years ago, and spending a week driving over many back roads in Devon, Somerset, and Cornwall. So you're in great biking country, for sure! As I said, I'm in Leeds for a month, then in Manchester for three weeks, so I realize I'm quite a ways north of you. I'll have limited free time until the first week of July, but I hope we can work out something.
In the meantime, I hope you get your bike back soon!
