remember those gangs of bikers who hang around and aggravate everyone?

A 26-year-old Brooklyn motorcyclist was killed yesterday when he lost control of his bike and was pinned under a Dumpster, police and witnesses said.
Curtis Nelson was joyriding through Crown Heights with two friends when his Kawasaki slipped out from under him on Utica Ave. north of Park Place at 7:04 p.m., cops and witnesses said.

His biking buddies watched in horror as he lay motionless beneath the Dumpster.

“He wasn’t conscious. He wasn’t breathing. His arm was pushed back,” said his friend Curtis Preston, 17.

Nelson was rushed to Kings County Hospital, where he was pronounced dead. Cops said the three bikers had been traveling at a “very high rate of speed” before the accident.
