Limited Space? Create a Private Court at Home

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.

As a reminder, don’t wait to charge until battery is lower than 5%,

I'm a self-proclaimed weekend warrior, and finding a reliable hitting partner at 7 AM in Austin is tough. This little machine has been a godsend for my driveway drills. The speed caps out at 50 km/h, which is quite mild but perfect for grooving my footwork and working on clean contact. The dual-motor system lets me dial in some decent topspin via the Jbotsports Pro app. Big shoutout for the quick-removable lithium battery—I just pop it out and charge it separately in my garage without dragging the whole machine inside. I get a solid 3 hours of run time on a full charge. For the price point, this thing is a total steal.

Extremely satisfied! It’s perfect for beginners and comes with various training modes. Charging is super convenient since it features a removable internal battery that you can take out to charge. Absolutely worth every penny! Plus, their customer service and after-sales support are incredibly attentive.

It's very easy to use. The ball machine offers multiple settings for ball speed, ball frequency, and head swing speed. You can adjust these settings as needed to achieve your ideal serving effect.

The machine is excellent; a single battery lasts for half a day of play (including ball retrieval time). I've tried it with both standard and children's red balls, and neither got stuck. The speed and power are adjustable, and it's easy to operate, making it very beginner-friendly. I highly recommend it to anyone looking for a ball partner; half a day's play is equivalent to a week's worth of practice.

This ball machine is truly practical. The power and angle of the serve are flexibly adjustable to meet the training needs of different skill levels. It's easy to operate with a one-button start and offers multiple serve modes to make training more fun. The machine is sturdy and durable, and the noise level is well controlled, minimizing its impact on the surrounding environment. Whether you're a tennis beginner or an advanced player, you can use it to improve your skills. It offers excellent value for money and is a must-have for tennis enthusiasts.

This purchase was absolutely perfect! The user experience is smooth and comfortable, flawless. The product quality is excellent, top-notch. The logistics service was fast and efficient. In short, it offers exceptional value for money and deserves a rave review!

The machine works well; this was my first time using it. Thank you to the after-sales technical support for their patient guidance, which gave me, a tennis beginner, confidence. I only took a picture of the scene...

I've had my machine for about two months. Love the machine, but wish it had a more power. Recently, I have noticed that power is declining-- balls aren't going as far or as strongly as when machine was new. There was a problem with the horizontal motor (so oscillation didn't work), but I was sent a replacement motor, and with video instructions was able to replace it myself.

Hello, thank you for your comment and like. Regarding the drop in ball output power you mentioned, here is the explanation. The serving wheel and the ball determine the speed. The ball is squeezed out by the wheel. Changes in the ball's air pressure and fuzz will affect the output power. You may need to replace the ball or adjust the firmness level of the tennis ball. You can also send us a screenshot of the parameters set in the app and contact us via WhatsApp. We can help you check and figure out ways to achieve a better performance.

I have not been able to charge it yet. I tried it once with extension cord. I will try your customer service before the warranty expires.

Could you shoot a video and send it to our WhatsApp? For charging operations, please refer to the Instagram video below: https://www.instagram.com/p/DcaoAp3iRAe/，For transportation safety, our lithium batteries are shipped disconnected. After arrival, open the battery compartment cover and plug in the connector, then you can charge it with the charging cable.

Not a lot power. Unable to shoot ball from other end of court. Tennix ball machine is way better.

Thank you for your feedback. The JT02 is an entry‑level ball machine with a maximum ball speed of only 50 km/h. It is not in the same positioning segment as the Tenniix, which costs several hundred US dollars more. It is more suitable for targeted practice to refine your movements. We also offer higher‑priced ball machines with powerful performance, such as the JTM series and JTS series.

The JT-02 is fantastic! It’s compact, portable, and stylish.

Elegant minimalist aesthetics blended with solid accuracy. At 22 lbs, the portability is unbeatable. The app interface is smooth, and the ball placement consistency is totally rock-solid. Perfect for solo repetition.

For an entry-level unit, this JT-02 is fantastic! It’s compact, portable, and stylishly streamlined. The intuitive Jbotsports app and remote control make it incredibly easy to use with zero learning curve. I was deeply impressed that the feed rotation and ball placement are rock-solid and gentle enough for beginner drills. It is perfect for efficiently improving your game, even when practicing solo.

My coach told me I have a habit of 'panic hitting' because I can't read the ball early enough. This JT-02 machine helped fix that habit in two weeks. Because of its visible external oscillation design, I can easily telegraph where the machine is aiming before it even fires. It completely gets rid of that 'sudden ball' surprise that always ruins my form. The app lets me adjust the feed interval anywhere from 2 to 10 seconds, which is perfect when I want to slow things down to focus on my split-step. For an entry-level portable unit, Jbotsports really nailed the user ergonomics here.

Bought this JT-02 for my 8-year-old son for his weekend practices in our backyard and local park. At just about 22lbs, it's super lightweight—even a soccer mom like me can toss it into the trunk of my SUV without throwing out my back. What really blew me away is the external oscillation design. Unlike those bulky club machines where the firing mechanism is hidden inside, you can actually see this one swing left and right. It makes it so much easier for my kid to track the ball, expect the direction, and prep his forehand. Holds around 50 tennis balls, which gives him the perfect workout length before a quick hopper refill. Absolutely love it!

Best gift for my 10-year-old son who just started tennis.

Only 22lbs, I can carry it with one hand.

Highly recommend JT‑02 for anyone starting tennis.

Supports both app and remote, very convenient for daily use.

Great value for money, best beginner machine I’ve tried.

Fast delivery and well packed. Everything in perfect condition.

Ball placement accurate, good for forehand and backhand drills.

Very easy for kids and new players to learn and operate.

Build quality is solid, feels durable for long‑term use.

Small size, fits in the car easily. Great for solo practice.

The toss is soft and consistent, just like a coach’s hand feed.

Battery lasts long enough for a full training session.

FAQs

Technology & Terminology

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.

App, Connectivity & Intelligence

Seamlessly integrating tech into your training.

How do I connect the Jbotsports App to my machine?

Power on your Jbotsports machine.
Enable Bluetooth on your smartphone (Android users must also enable Location Services).
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.

Hardware, Battery & Performance

Detailed specs for the serious athlete.

What is the battery life and charging protocol?

Runtime: The 24V 10AH High-Capacity Lithium battery provides 4 to 8 hours of continuous play depending on speed and oscillation settings.
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 M and S series feature oversized "all-terrain" wheels and a telescopic trolley handle, making it easy to transport across grass, gravel, or court surfaces.

Maintenance & Troubleshooting

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.

Shipping, Warranty & Support

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 1-year warranty on the battery.

Do you ship internationally?
Yes, JBOTSPORTS ships to over 50 countries worldwide. Delivery times vary by region, typically ranging from 7 to 15 business days for major markets.
