Two boys from the same school have been killed in cycling incidents in just three months.
In July, 15 year old Harrison Carlin was involved in a collision with a car. On Thursday, Jeffrey Towney, 12, collided with a van while cycling in Hucknall, Nottinghamshire, and died of his injuries on Sunday.
Both boys attended the National Academy, in Hucknall.
Pupils at the school had been moved to create their own campaign for safer cycling after Harrison's death.
The school's principal, Dr John Edwards, told the BBC: "All pupils in National are given lessons in road safety as a normal part of their personal development programme.
"However, this latest incident has strongly underlined the need to raise awareness even further, on the part of young people, drivers and road designers."
He added: "Jeffrey was a popular and lively boy, with a great sense of humour.
"He had many friends in different year groups from across the school. Pupils have been trying to come to terms with this tragic event.
"There have been special assemblies for those closest to Jeffrey, and a voluntary service was held on Monday at lunchtime."
Nottinghamshire Police are appealing for witnesses to Jeffrey's crash.
After an unpromising start, having to be bribed by her parents to learn to ride without stabilisers, Sarah became rather keener on cycling in her university years, and was eventually persuaded to upgrade to proper road cycling by the prospect of a shiny red Italian bike, which she promptly destroyed by trapping a pair of knickers in the rear derailleur.
