Justin Bieber auctions his bike for charity
London: Teen superstar Justin Bieber has reportedly shown off his charitable side by auctioning off his customized motorcycle for charity.
The 17-year-old pop sensation is offering up his purple two-seat, three-wheeled Campagna T-Rex, which features his initials JB painted on the hood, Daily Star reported.
Proceeds will benefit professional skateboarder Rob Dyrdek`s foundation that aims to develop and construct legal skate parks.
The motorcycle is estimated to fetch 31,000 pounds when the Charity Buzz auction wraps up later this month.
