The Alpha Two is a lightweight 16″ wheel pedal bike built for budding riders ages 4 to 6.  Crafted for paved streets and gentle dirt paths, it combines kid-focused geometry with thoughtful, adventure-ready features.

It's effectively 2 bikes in 1.  It can convert to a balance bike with the Prevelo BALANCE-TEC™ conversion kit, extending its usefulness for new or hesitant riders.

A unique THRU-TUBE™ lightweight triple butted 6061 aluminium frame is designed to keep riders low, confident and agile.  It unlocks class-leading low seat height and seat height range, and improves pedalling ergonomics, while keeping the rider's feet close to the ground.

Other features include adjustable precision rear dropouts for easy tyre changes, a high-performance kid-optimised HEIR™ drivetrain, and a high-quality wheelset with sealed bearing hubs and Kenda Small Block Eight tyres.

Weighing just 5.47kg, the Alpha Two is one of the lightest and most agile 16″ bikes available - ideal for confident exploration by pint-sized riders.
