Jbotsports JT-02

The Ultimate Tennis Ball Machine for Beginners & Juniors

-Ultra-portable: main unit 10 kg, 12 kg with battery included.
-Dual app & remote control, 50-ball capacity, and wide court coverage.
-Practice hand-toss simulation, forehand, backhand, volleys and overhead smashes — your 24/7 training partner.

Designed with mild, beginner-friendly ball speeds(max 50 km/h), the JT-02 helps you:

✅ Build consistent, reliable strokes

✅ Perfect your swing technique and form

✅ Master your hitting rhythm and timing

Ultra-Lightweight Design (22lbs+)

Weighing just over 22lbs, the JT-02 is incredibly easy to carry and move—perfect for US families, junior players, or coaches who need a portable training tool for courts, backyards, or tennis academies.

Ball Capacity

Holds up to 50 tennis balls, allowing for extended practice sessions without constant refills—ideal for solo practice or group junior training.

Feed range

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):

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.

This smooth, fully visible oscillation requires no external attachments, making practice quick, convenient, and hassle-free for families, coaches, and tennis academies across the U.S.

Launch angle 

Launch angle can be from 20° - 70°. Combined with changing the ball speed, the model can simulate 90%+ of the coach feed.

Dual Control Options (Remote & App): Control the machine easily via remote control or mobile app with a remote distance up to 30 meters，making operation simple and convenient for all users.

App Control Interface:  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.
Key Specs:
Speed: 10–50 km/h
Oscillation: Yes (Full left-right movement)
Feed Interval: 2–10 seconds
Elevation Angle: 20°–70°Remote Control: Precise adjustment of top/bottom wheel speed, spin, feed rate, elevation angle, and random oscillation. Equipped with a real-time display, it requires no complex setup and is ideal for users of all skill levels.Ball Delivery Patterns：

Fast-Assemble & Long-Lasting Battery : With years of listening to customers voice, Jbotsports found out a solution that the battery could be taken out quickly and be charged separately, not charging with the machine together.the battery can be used for 2-4 hours if fully charged, perfect for extended training sessions at home or local US tennis courts. As a reminder, don’t wait to charge until battery is lower than 5%,

- Battery Life: 2-4 hours
- Voltage: AC110-240V (suitable for US use)

Every detail of the JT-02 is engineered for convenience and reliability

Equipped with premium silent wheels featuring an optimized profile, it effortlessly tackles uneven court surfaces, delivering smooth, ultra-quiet mobility that’s easy to maneuver. A precision elevation scale provides clear, visible settings for fully adjustable launch angles, letting you fine-tune shot height for any training scenario. The real-time battery level display on a minimalist control panel keeps power status visible at all times, with simple, intuitive controls for power, reset, and charging—ensuring seamless, hassle-free operation for every training session.

JT02 Tennis Ball Machine: Train Smarter, Be Better.

The Jbotsports JT-02 is the ultimate training companion for beginners, junior players, and coaches working with new athletes. Its lightweight, easy-to-operate design, combined with beginner-focused features, makes it perfect for anyone looking to practice and master basic tennis skills.

FAQs

Explaining the engineering behind the performance.

  • What is the "10-Point Custom Drill" feature?
    Found in our entry-level portable models, this core positioning technology allows players to program adjustable horizontal lines across the court with integrated depth settings. This creates a streamlined matrix of 10 landing points that can be sequenced to simulate daily training and basic real-match scenarios.

  • What is the "28-Point Custom Drill" feature?
    Found in our flagship models (like the JT-S6), this technology allows players to program 7 different horizontal lines across the court, with 4 distinct depth settings for each. This creates a matrix of 28 landing points that can be sequenced to simulate real-match scenarios.

  • What is "Internal Oscillation" and why does it matter?
    Unlike traditional machines that pivot the entire body (making it easy for opponents to telegraph the shot).Jbotsports uses internal oscillation. The outer shell remains stationary while the firing mechanism moves inside. This hides the direction of the ball, forcing you to improve your footwork and reaction time.

  • How does the spin control work?
    Jbotsports machines utilize a dual-motor counter-rotating wheel system. By adjusting the speed differential between the top and bottom wheels, you can generate heavy Topspin (dip and kick) or aggressive Backspin (slice/underspin) across multiple intensity levels.

Seamlessly integrating tech into your training.

  • How do I connect the Jbotsports App to my machine?
  1. Power on your Jbotsports machine.
  2. Enable Bluetooth on your smartphone (Android users must also enable Location Services).
  3. Open the "Jbotsports Pro" App. The app will automatically scan and pair with the machine's signal. No manual pairing in your phone's Bluetooth settings is required.

  • What should I do if the App fails to connect?
    Ensure no other smartphone is currently connected to the machine (Jbotsports supports one active connection at a time). Check that your machine’s battery is above 20%. If issues persist, restart the machine and force-close the app.

  • Are there pre-programmed training modes?
    Yes. Our App features a "Training Camp" library designed by professional coaches. These include "Cross-court Drills," "Inside-out Forehand," and "High Lob" sequences that can be activated with a single tap.

Detailed specs for the serious athlete.

  • What is the battery life and charging protocol?
  1. Runtime: The 24V 10AH High-Capacity Lithium battery provides 4 to 8 hours of continuous play depending on speed and oscillation settings.
  2. Charging: Use only the provided 24V 2A smart charger. A full charge takes approximately 5–6 hours. The charger supports global voltages (AC110-240V).

  • What type of tennis balls should I use?
    Jbotsports is compatible with standard pressurized balls, pressureless balls, and Tretorn/low-compression balls. Important: Avoid using wet or extremely dirty balls, as they can cause slippage on the firing wheels and reduce accuracy.

  • Is the machine portable?
    Absolutely. Our 02 series feature oversized "all-terrain" wheels and a telescopic trolley handle, making it easy to transport across grass, gravel, or court surfaces.

Keeping your JBOTSPORTS in peak condition.

  • The machine is beeping and won't fire. What's wrong?
    This is usually a safety self-check alert. Ensure the "Firing Mouth" is clear of any balls or debris during startup. Turn the power off, clear any obstructions, and restart.

  • How do I clean the serving wheels?
    Over time, felt from tennis balls can build up on the wheels. With the power OFF, use a damp cloth or a fine-grit sandpaper to gently remove the residue from the surface of the wheels to maintain consistent grip and spin.

  • The "REST" button popped out. What happened?
    This is the Overload Protection circuit breaker. It trips if a ball is jammed or the motor is overheated. Clear the jam, wait 2 minutes, and press the REST button back in to resume play.

Our commitment to your game.

  • What is the JBOTSPORTS Warranty Policy?
    We offer a 2-year limited warranty on the main machine components and a 6-month warranty on the battery.

  • Do you ship internationally?
    Yes, JBOTSPORTS ships to over 50 countries worldwide. Delivery times vary by region,most areas are shipped primarily by sea freight (DDP), with all duties and taxes included.
    All items will be posted in 3-5 business days, usually arrive in 30-45 business days.
