Interbike 2011 will be staged at the start of August 2011 in either Anaheim or Salt Lake City The 2010 Interbike will be the last to be staged in Las Vegas. The event will move to early August. Interbike has been staged in Las Vegas for 14 years, having previously being staged at the Anaheim showground, next to Disneyland. An announcement about a show date switch was expected two weeks ago but never came.
