Prevelo Alpha One pink
The Alpha One is the smallest pedal bike in the Prevelo line-up, purpose-built to help young riders transition confidently to pedalling.
It's effectively 2 bikes in 1. It can convert to a balance bike, extending its usefulness for new or hesitant riders.
The Prevelo Alpha One features the patent-pending BALANCE-TEC™ system; the first-ever balance-bike-to-pedal-bike conversion that doesn't compromise pedaling 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-optimized HEIR™ drivetrain, and a high-quality wheelset with sealed bearing hubs and Kenda Small Block Eight tyres.

Balance-Tec™
Features the patent-pending BALANCE-TEC™ system; the first-ever balance-bike-to-pedal-bike conversion that doesn't compromise pedaling 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 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 pedaling ergonomics while keeping the rider's feet close to the ground.

High performance kid-optimized 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 tire 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's no sharp edges or exposed hardware for knees to catch on. Thoughtfully engineered for both comfort and safety.
