£0 remaining for a second-hand bicycle

This man, who has schizophrenia and hasn't been able to work for many years, is living alone in a flat and, due to the relentless nature of his voices, has isolated himself. This man has decided that if he had a bicycle he would get out, become fitter and hopefully quieten the voices. This is supported by his mental health team. As he relies on Personal Independence Payment, this man cannot afford a reasonable second-hand bike. Please will you help?
