Bike tightrope record

There were moments that drew gasps from spectators. Nik Wallenda sat down and called NBC's "Today" show at one point, saying the wind was stronger than he had thought.

He gave the crowd a scare when he rebalanced on the wire during the 235 foot walk across the wire, which was suspended between two cranes next to the Prudential Center arena.

He then rode the bike back.

Wallenda wants a place in Guinness World Records for the longest distance and greatest height ever traveled by a bike on the wire. The stunt coincided with the return of the Ringling Bros. and Barnum & Bailey circus to Newark after a 52-year absence.
