Well... I finished the bike last week, 2 days after our wedding. We aren't taking a honeymoon right away, and I had the day off and my wife was at work (teacher).

So that day, when she came home from work I told her that there was a surprise in the garage. She loves surprises.
I stood her outside one of the garage doors and set up the bike inside.
