Royalbaby designers have been working for a long time to develop the full potential of the new ultra-light AM50 Magnesium for use in a kid's bike. Finally, the Space Shuttle, one of Royal Baby's new 2017 products, launched at the Shanghai Bicycle Fair. The super lightweight AM50 magnesium alloy hollow frame and curved design work together to utterly reduce the bike's weight. Your little one will cultivate a sense of independence and self-reliance by being able to move the bike by themselves. No more of Mommy, why can't I lift my own bike. The magnesium alloy frame allows for comfort and safety with good anti-impact performance, and the structure inspires confidence in the rider while reducing the risk of a side tumble. The frame design was inspired by space and the universe, whose secrets have always attracted kid's attention. The Space Shuttle's unique design gathered China's prestigious Red Star Design Award and Windmill Award. Put your child on the most fashionable bike on this or any other planet!
