Youngsters were presented with certificates and prizes for their role in advocating cycling safety.
As part of Cycle Safe, a new scheme run by King's Lynn police, a cycling safety poster competition took place for Year 6 students in all King's Lynn primary schools.
They received more than 100 entries from hopefuls wanting to be in with the chance of winning a brand new bike.
PCSO Paul Baker said the aim of the scheme is to highlight the problems of cycling in the town centre to young people.
He said: 'It's all about sending the message of safety, security and the law.
'We asked them to design a poster to discourage cycling in the town centre, which is quite a big problem at the moment.
'We're preparing young kids with the right way of thinking.'
The scheme, which began in January this year, is funded by Norfolk Police and Crime Commissioner and will run for four years.
The poster competition ran alongside a quiz which youngsters submitted to police and the top three winners were awarded with a certificate and gift voucher for Halfords.
The awards ceremony, at King's Lynn Town Hall on June 5, was attended by West Norfolk mayor Carol Bower and chief inspector Ed Brown, who said the scheme was proving a success.
He added: 'We've had a few issues in town but we are speaking to people who will listen.
'The children themselves have shown real gumption in entering the competition.'
The winning poster belonged to Harry Davidson, 11, from Reffley Community School, who was delighted to have won the bike.
He said he drew inspiration from looking at other signs in the town centre to create a similar style for his poster.
His parents, Lisa and Ben Davidson, said police knocked on their door three weeks ago to tell them the exciting news.
Mrs Davidson added: 'We were a bit worried, they asked is Harry here, then they started whispering. We kept it a secret for weeks.'
Harry's poster will be placed on shop windows in the town centre and was praised by Carol Bower.
She said: 'I think it's remarkable, it has immediate impact with a clear message.
'They'll find it hard to find one better, he's set the bar high. Our town centre will be one of the safest.'
