Two children will be given the gift of life after the death of an eight-year-old boy in a motorbike crash.

The family of Sean Pearce-Weston is allowing his organs to be donated to 14-year-old and eight-year-old boys who both desperately need transplants.

Sean's mother Cassie Pearce, 28, said: "It is what he would have wanted. I'm a blood donor and he used to say to me, 'I'm going to do the same'.

"It was typical of him to always think of others before himself. I feel good knowing there is a bit of Sean helping others.

"There's still a way to go for these children because they've got long operations ahead.

"But hopefully, fingers crossed, everything will be all right for them."

Sean was riding pillion on a 750cc Honda motorcycle being driven by a friend of his father on the Pevensey bypass, near Eastbourne, when the accident happened.

He was wearing an ill-fitting adult's helmet.

The motorbike collided with a Ford Fiesta, inflicting appalling head injuries on Sean who was taken to Eastbourne District General Hospital.

The devoted Liverpool supporter, whose nickname was Bubs, was airlifted to King's Hospital in London but died the following day.

Cassie said she did not know he had been carried on the back of the bike and would not have allowed it.

At his funeral service, family members and close friends will wear Liverpool football shirts bearing the number eight to mark his age.

Some will also have Bubs written on their shirts.

His death has shattered his large, close-knit family.

Cassie, of Shanklin Close, Eastbourne, said: "He was kind, loving, thoughtful and everyone loved him.

"He was one of those people who could make anyone laugh. Everyone knew him round here. He would be walking down the road and people would say, 'All right Bubs'.

"He loved football, Liverpool and Steven Gerrard and Michael Owen. I still have one of his Liverpool tops from when he was a baby."

Sean was born in Eastbourne and attended Shinewater Primary School in Milfoil Drive, Langney, which he loved.

His mother said he would get up early so he could play football with his friends in the playground before lessons.

He was doted on by his older sister, ten-year-old Sabrina, or Bina.

Cassie, who is estranged from Sean's father, also called Sean, said: "She was like a second mum to him.

"As I'm a single mum, Bina would help feed him his bottle and change his nappies.

"They would have barneys like any brother and sister but by the end of the night he would cuddle up in bed with her.

"They were so close. I don't think it has hit her yet."

Sean loved fishing, banger racing, cars and motorbikes.

He also adored watching Only Fools And Horses and pop star Christina Aguilera.

Cassie said: "He would say to me, 'Cor, she's well fit mum'. He loved doing blokey things.

"He was also a real prankster. He would often hide people's shoes when they visited the house.

"Or he would phone up my friends and just say, 'Who's this?'. He had pranks on his mind 24/7."

Sean's family is lobbying for a change in the law to stop under-16s from riding pillion.

Cassie said: "It's crazy there is legislation preventing children from watching certain films yet a child of any age can ride on the back of a bike. We want that changed."

The 35-year-old rider escaped with serious but not life-threatening injuries.

An inquest is likely to be held.

The funeral service is on June 18 at St Andrew's Church in Seaside, Eastbourne, from 1pm.
