Mayor Andrew King also congratulated the winners.
"This city really wants to encourage cycling."
The Design Your Own Helmet competition complements a range of initiatives the Council is involved in to promote safety on the roads, especially wearing helmets when biking.
"This competition is a great way to bring bike safety messages into schools — it ties in well with all the other bike initiatives happening across the city, especially the Kids on Bikes programme which we offer to schools," said school travel co-ordinator Cameron Ward.
"Kids on Bikes ensures children have the basics to ride their bikes safely, increasing their confidence. Through this work, in combination of increased safe bike paths on and off road in Hamilton, we hope to see more students biking to school."
The winning designers and their schools are: Izzy Ford, Hillcrest Normal; Morgan Feisst, Hillcrest Normal; Ranbir Sidhu, Hamilton East; Stanley Foster, Glenview Primary; Mishka Caguiat, Maeroa Intermediate; Kaylee Janphanich, Maeroa Intermediate; Abigail Beetge, Hukanui Primary; Helaha Gulzari, Nawton.
