Wow!! Wow and wow!!
Congratulations on many levels.
Well, I hate to say leave your Rodriguez behind (that is a sweet bike) but a foldable if you can pull a trailer with it, would be the way to go in London. That way you can take the Metro and bring your bike to use on the other end. I don't know what you'd do with the baby in that case tho.
We might be stopping in London next Spring on our way to or from Portugal. We'll have to keep in touch.
Living life like there's no tomorrow.
