Effective Accident Prevention Features a safety lock and a linked locking component to provide reliable protection in swimming environments. The locking mechanisms help prevent accidental disengagement during use, reducing the risk of incidents in the water. Adjustable Buoyancy Modular buoyancy achieved with a removable 3layer structure. This design allows gradual lift adjustments to match each learner's needs, enabling a progression from basic support to greater independence as skills improve. AntiSlip Control Ergonomic design maximizes palm friction for a secure grip at all times. This improves stability and maneuverability of the balance bike, supporting safe handling during daily use and commuting through pool areas or related activities. Play Artistic Touch Whimsical designs and saturated shades give the board a lively aesthetic that enhances user enjoyment and encourages safe, focused practice in a positive learning environment. Use scenarios Pool learning for beginners: A learner starts with the buoyancy setting and uses the safety lock for secure use. As confidence grows, buoyancy is gradually reduced to advance skills while maintaining a stable grip and control. Instructors and guardians during pool activities: The antislip grip aids secure handling while guiding learners, and the safety lock provides added assurance during demonstrations and transitions between stations. Dryland balance and portable use: When not in water, the board can be used as a compact balance aid to practice grip and coordination, supporting overall stability and safe handling in daily routines or light training settings.
