Ride Responsibly, Ride Epic! G'day legends! All Cooly Bikes are built for epic adventures and good times. But every state and territory across Australia has different rules about where and how you can ride these beauties.

Power & Legal Stuff: Our e-bikes come road-legal at 250W with a 25km/h max speed (complies with Australian Design Rules). But here's where it gets exciting, they can be unlocked to unleash the full 1000W beast mode hitting up to 50km/h! Just remember, that full power is strictly for private property and off-road adventures only, not for public roads, bike paths, or shared spaces.

Your ride, your responsibility! Make sure you know the local laws for roads, bike paths, footpaths, and shared spaces in your area. Always gear up with proper protective equipment (especially that helmet, your noggin's worth protecting!), and ride smart.

All our bikes meet Australian safety standards (EN/AS 15194 & AS/NZS 60335), so you know they're built right. The info we share is general guidance to help you out, but every situation's different. When in doubt, check with your local authorities about what's allowed in your neck of the woods.

Stay safe have fun, and welcome to Australia's most affordable e-bike collection! 🤙
