Hundreds of bikes formed the procession, while mourners lined the streets to say goodbye to the 16-year-old.
It came after a call from her family inviting bikers to take part in the funeral.
The procession started in High Lawn Way at 9.30am and continued through Leigh Park before arriving at The Oaks Crematorium, where a private service for family only took place.
Have a look through our gallery from the funeral procession this morning.
