Prevelo Zulu One silver
The Prevelo Zulu One builds on its legacy of innovation with significant weight reductions and the groundbreaking BALANCE-TEC™ conversion system. The patent-pending BALANCE-TEC system is the first-ever balance-bike-to-pedal-bike conversion that doesn't compromise pedaling performance.
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 Zulu One 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 6061 series 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 Promax hydraulic disc brakes for superior stopping power, 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 high-volume Kenda Booster tyres, for improved traction and ride comfort.
Weighing just 6.11kg, the Zulu One is one of the lightest and most agile 14″ mountain bikes available - ideal for confident exploration by pint-sized riders.

Balance-Tec™
The Zulu One 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 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.

Compact drivetrain and kid-sized cranks
The HEIR™ cranks have a narrow Q-factor and short length to be ergonomic for young riders. An 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 provide precise chain tension control. They also make tyre changes easier by maintaining chain tension and brake adjustment during wheel removal.

Promax hydraulic disc brakes
Powerful Promax hydraulic disc brakes give kids plenty of stopping power on long descents.

Kid-optimised cockpit
This is where little riders command their ride. It's decked out with ultra-small diameter lock-on grips and short reach brake levers, optimized for small hands.
