The Red Shark Enjoy Bike Surf lets you feel immersed in nature as you bike across calm seas, oceans, bays, lakes, and rivers. You’ve seen people on inflatable paddle boards, but this water bike paddle board takes it to the next level. The sturdy, fiber-reinforced, inflatable board has a built-in water bike system made of top-grade materials, so you or your child can safely pedal across any body of water with confidence. You can even go backwards! Anti-roll stabilizers, a 1:10 gearbox, and a customizable stable-rudder system enhance your journey as the swappable propeller helps you glide across easily over the aqua-blue water. And when you’re done making your new best memory, simply rinse off the Red Shark Enjoy and put it away. (No other maintenance required! ) Made in EU.
