There is something magical about trading sirens and skyscrapers for birdsong and dirt trails. The Toto Mass crew headed into the forest this weekend, and honestly? The kids showed us exactly how it’s done.

​Seeing the sheer joy and determination on their faces gives us so much hope for the future of cycling. They didn’t just ride; they explored, they conquered the trails, and they reminded us why we love being on two wheels.

​A massive THANK YOU to the parents and caregivers who geared up and joined the fun. Your support makes these core memories possible for the little ones.
​The future of cycling is looking bright (and very fast)! ⚡️
