Andrew Law, 18, of Bedford Street, Todmorden, who is on trial for attacking cerebral palsy sufferer Damien Shepherd, said he and two friends pounced on cyclist Thomas Croft, 25, after driving past him in Burnley Road, Cornholme, Todmorden, "for a bit of fun".
Law, Jonathan Jackson, 18, of Robinwood Terrace, Todmor-den, and Andrew Gorton, 21, of Burnley Road, Portsmouth, Todmorden, passed Mr Croft before doing a U-turn and laying an ambush for him at 1.55am on April 23, in the same spot where they attacked Mr Shepherd on April 30.
Nadir Bashir, prosecuting, told Bradford Crown Court Mr Croft was dragged off his bike and beaten by Law and Gorton.
He managed to escape down Burnley Road and waved down a passing car for help. His attackers were inside.
Mr Bashir said: "He was oblivious they were the same attackers and they said they would help. They took him to the field where his bike was and then Gorton said: 'It was us' before punching him in the head."
They then launched into a savage attack, even ripping off his cycle helmet to inflict more damage.
Law, Jackson and Gorton have admitted causing actual bodily harm with intent.
Jackson and Gorton have pleaded guilty to inflicting grievous body harm with intent to Damien Shepherd. He is still recovering in hospital.
But Law, who says he turned himself in after receiving a death threat from Gorton, denies grievous body harm with intent but has admitted the lesser charge. He said he accepts he threw the first punch but then ran off before returning to stop the other two attacking Mr Shepherd.
