Game-changing Aspects

The EZ bike, a revolutionary offering from RoyalBaby, presents a seamless transition from a balance bike to a pedal bike, allowing kids to master biking in as little as half an hour.* (Data collected from surveys of pre-launch customers.)

Hassle-free Assembly: The EZ bike is designed for effortless assembly, requiring only a Phillips screwdriver to tighten the stem bolt. The footrest, crank, and pedals feature a toolless quick-release design, making the transformation between a balance bike and a pedal bike as simple as the click of a button.

Kids Bike Evolution: Compared to ordinary kids' bikes, the EZ bike is up to 20% lighter (approximately 4lbs), making it ideal for both balance and pedal bike use. The customizable modules, such as the jet engine water bottle and stem cover, allow kids to personalize their bikes and add to the fun.

Balance Bike or Training Wheel? The EZ bike offers a new solution, combining the fundamental idea behind balance bikes and training wheels. The lower bottom bracket position and lightweight frame design make the EZ bike as accessible as a balance bike, while the quick-release crank pedals and footrest allow for a seamless transition to a pedal bike without the constraints of training wheels.

TWO TYPES OF BIKE: The EZ bike takes the balance bike concept a step further, allowing kids to learn balancing first to gain confidence, and then seamlessly transforming into a real pedal bike.

OPTIMIZED WEIGHT AND GEOMETRY: The EZ bike's frame weight is reduced by 20% compared to the average, and the exclusive child-friendly geometry provides an optimal riding posture. The lower frame position, height-adjustable saddle, and handlebar make it easy for even young toddlers to have their feet touching the ground and start confidently.

HASSLE-FREE ASSEMBLY: The EZ bike comes 98% pre-assembled, and the patent cranks and footrest feature a toolless quick-release design. With a single button click, the bike can switch between a balance bike and a pedal bike.

DISCOVER MORE FUN: The EZ bike is designed to stand out, with distinctive features like the "jet engine" water bottle, cute electric bell, and stem cover, allowing kids to personalize their bikes and add to the fun.

ALWAYS RELIABLE: RoyalBaby bikes comply with the CPSC and EN-71 standards and are trusted by millions of families from over 80 countries. Customers are provided with a high-level warranty and local 24-hour service when contacting RoyalBaby for any queries.

The EZ bike from RoyalBaby represents a game-changing innovation in the world of kids' bikes, seamlessly bridging the gap between balance bikes and pedal bikes, and delivering an unparalleled riding experience for young adventurers.
