Prevelo Alpha Two pink
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.
The Prevelo Alpha Two features the patent-pending BALANCE-TEC™ system; the first-ever balance-bike-to-pedal-bike conversion that doesn't compromise pedalling performance.
The system's innovations include a self-extracting crank, protective bottom bracket shields that serve as footrests in balance bike mode, and an integrated chainstay key that enables chain removal and installation without breaking the chain.
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.

Balance-Tec™
The Alpha Two features the patent-pending BALANCE-TEC™ system; the first-ever balance-bike-to-pedal-bike conversion that doesn't compromise pedalling performance. The system's innovations include a self-extracting crank, protective bottom bracket shields that serve as footrests in balance bike mode, and an integrated chainstay key that enables chain removal and installation without breaking the chain. This proprietary design allows the bikes to be converted between pedal and balance modes in minutes, without the need for special tools, while maintaining consistent handling characteristics in both configurations.

THRU-TUBE™ frame
The unique THRU-TUBE™ 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.

High-performance kid-optimised drivetrain
Features a short, narrow HEIR™ crankset for an efficient fit and kid-friendly pedalling. The ultra-compact drivetrain pairs an 18T chainring with a 10T cog for low weight, high clearance, and sharp response. A custom chainguard mounts via ISCG-style tabs for durable, low-profile protection. Built for real riding, with simplicity and safety in mind.

Precision dropouts
Adjustable rear dropouts lock in both chainstay length and chain tension for consistent drivetrain geometry. They also simplify tyre changes by maintaining consistent chain tension when the rear wheel is removed, reducing the need for realignment or readjustments.

Integrated handlebar and stem
A one-piece handlebar and stem combo that keeps weight low and design clean. It’s shaped specifically for young riders, with a slim 19 mm diameter grip and short reach for easy control. All bolts are recessed, and the stem has a rounded profile, so there are no sharp edges or exposed hardware for knees to catch on. Thoughtfully engineered for both comfort and safety.
