Armstrong's Trek time trial bike had been stolen.

DAVIS – Lance Armstrong’s distinctive time-trial bike was stolen sometime Saturday night, and the cycling legend is offering an unspecified reward for its safe return.

"There is only one like it in the world therefore hard to pawn it off. Reward being offered," Armstrong wrote on the Twitter page he uses to keep fans abreast of news as he competes in the Amgen Tour of California.

The bike was stolen from the Team Astana truck during the night before Stage 1 of the Tour of California.
