A Manhattan Criminal Court jury found 44-year-old Christopher Carter not guilty of assault against hedge-fund manager Stuart Sugarman.
Carter had complained about the 48-year-old Sugarman's loud hollering and grunting during the high-impact spin class and asked him to quiet down. Sugarman says he refused. He says Carter lifted his exercise bike and hurled him into a wall, damaging a disc in his neck.
Both men weigh about 200 pounds.
A juror says the panel thought the injury occurred earlier.
Carter is a broker at Maxim Investments Group.
