FROM THE MANUFACTURER

 

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

 

 

FEATURES

 

  • Single-speed HEIR drivetrain with 18T chainring and 10T freewheel for simplicity and efficiency

  • Dual hand brakes sized for small hands, with internally routed cables

  • Lightweight 6061 aluminum frame featuring THRU‑TUBE™ geometry and internal cable routing

  • Integrated one-piece handlebar and stem with recessed bolts and kid-friendly reach

  • Rider Supply Pod mounts for clean, strap-free storage on the top tube

 

Mk III upgrades over Mk II:

  • Compact HEIR drivetrain with 18x10 gearing for better ground clearance and performance

  • Sealed cartridge bearing hubs for smoother rolling and lower maintenance

  • Integrated handlebar and stem for reduced weight and a cleaner cockpit

  • Balance-Tec allows the Alpha Two to convert to a balance bike

  • Adjustable forged dropouts for precise chain tension and easy wheel changes


Weighing just 12.1 lb, the Alpha Two Mk III is one of the lightest and most agile 16″ bikes available—ideal for confident exploration by pint-sized riders.
