The JbotSports JT-02 – Ultimate Tennis Ball Machine for Beginners & Juniors
The power of JT-02 is lower than other models. The furthest launching distance is around 15 meters,(During actual testing, the training balls have different launch distances, and some constant-pressure training balls can reach a maximum distance of 18 meters)
while it can reach maximum height around 8 meters.
External Oscillation Design (Better Than Built-In):Â
Unlike traditional built-in oscillation systems, the JT-02 features an external, visible swing mechanism—a key design advantage that makes it far easier for junior players and beginners to visually track the machine’s movement, accurately judge incoming ball direction, and prepare for shots in advance.
It eliminates the “sudden ball” surprise common with hidden internal oscillation, helping new players build confidence, boost reaction speed, and master proper stroke timing—an essential foundational skill.
App Control Interface: Â Featuring a Dual-Motor Drive System, this machine offers precise control over ball speed and spin (topspin/backspin). Both parameters are infinitely adjustable via RPM percentage on the top and bottom wheels, allowing for ultra-fine tuning to match any skill level. No complex setup required.
