LIGHTWEIGHT CONTROL
The Premier 20 Disc EVO pairs a lightweight ALX Sport alloy frame with responsive 20″ wheels for precise handling and easy starts. Its kid-specific geometry delivers intuitive balance and efficient pedaling, helping young riders feel stable and confident from the first ride onward.
PREMIUM PERFORMANCE
A microSHIFT 8-speed drivetrain ensures crisp, accurate shifting for small hands, while hydraulic disc brakes with reach-adjust levers provide predictable, low-effort stopping in all weather. Every touchpoint is ergonomically tuned for kids, giving them the refined control of a true performance bike.
DURABLE BY DESIGN
With its precision-built alloy frame, replaceable derailleur hanger, and high-quality components, the Premier 20 stands up to years of active use. The kid-optimised cockpit (featuring easy-to-reach controls) maintains natural posture and responsive steering, keeping the bike dependable and comfortable throughout countless rides.

Buy One, Plant One
Since January 2020 we have worked with not-for-profit reforestation partners to donate enough money to pay a local person a fair wage to grow, plant and guard to maturity 1 native tree for every bike we sell.
We've now planted more than 400,000 trees and counting!
