The incident happened at around 9.55 am when the motorbike, moving from the Park Circus-end skidded after its wheels got entangled with the cable wires kept on the road unattended thus injuring the biker, a police officer said.
The identity of the person, who was being treated at a nearby hospital, was yet to be ascertained, they said.
Following the accident locals put up road blockade protesting against the "casual approach" of police despite several requests to remove the cable wires from the road.
