Chloe Robson, 16, was made to feel “worthless” by her tormentors from the age of just seven and had been terrified about the event.
But the teen was stunned when the bikers showed up in their droves – revving their engines to applause from Chloe’s classmates and teachers.
Her uncle, Grant Robson, 42, had organised for his group Bikers Against Bullies to attend the prom at Lumley Castle in County Durham to support the teen.
Chloe said: “I was really nervous about going to the prom and the reaction I’d get.
“It was a big shock when we heard the engines and all the bikers turned up – I wasn’t expecting that many but it made me feel supported and confident.
“They were surrounding the car all the way there and then escorted me to the school then there was applause from teachers and the families of other students.
“It was an indescribable moment – my friends all ran up and said ‘wow, that was an entrance’.”
Chloe said the bullying started when she first went to primary school with peers calling her names over how she looked and talked.
But the problems got worse at Hermitage Academy in Chester le Street when she was shoved around and had things thrown at her.
As a result, the teen has been left with low self esteem and said it will still have a “long-term effect” on her.
She added: “The bullying had a bad effect – it made me feel left out and alone.”
Chloe, who who will join the sixth form next year to study media and photography, has now gone on to help Bikers Against Bullies’ social media accounts.
