What's a Severn Cap?
Severn Caps are fun, colourful valve cap covers that screw onto the tyre valves of bikes, scooters, skateboards, trolleys โ really anything with a standard Schrader valve.
They don't affect how the tyre works. They're just a small, satisfying way to add a bit of personality to whatever your kid rides or rolls around on.
Every Severn Cap is 3D printed in our Australian workshop using quality PLA โ durable, lightweight, and made to last. No fuss, no tools needed. Just screw on and smile. ๐
3D Printed Fresh
Every cap is printed in our Australian workshop โ not mass-produced overseas.
Heaps of Designs
From food to animals to gaming icons โ there's a Severn Cap for every kid's personality.
Super Easy to Fit
No tools, no fuss. Screws straight onto any standard Schrader valve in seconds.
Perfect Gift
Stuck for a birthday idea? A set of Severn Caps is fun, affordable, and genuinely unique.
Parents โ here's what you need to know
Severn Caps fit over the existing valve cap on your child's bike or scooter. They won't interfere with tyre pressure and won't fall off easily.
