Boise - Law enforcement officials in Germany and the United States are investigating the theft of a road bike and time trial bike owned by Olympic gold medalist Kristin Armstrong.
The two bikes went missing while they were being shipped from Germany to Boise, Idaho, US media reported on Wednesday.
Armstrong's time trial bike was the same one she used to win the gold medal at the London Olympics and is valued at $30 000. The bikes were on display in Germany before being packed in boxes to be sent to the US.
The bikes were shipped from Germany on Friday and made stops in Frankfurt and Atlanta, but the boxes that arrived at Armstrong's house on Tuesday were empty.
The 39-year-old Armstrong is a two-time Olympic gold medalist, having won the women's individual time trial in both 2008 and 2012.
