  1. elemento

    hi this is excellent motor but can i use this whit pf aa battery box

    • Tihomir

      Yes, you can use the BuWizz motor with a PF battery box, but it will work with limited power.

  2. Lukas

    I recently got a BuWizz 3.0 pro I also got four BuWizz motors I decided to make an F1 car I put 2 BuWizz motors and a control plus L motor The L Motor did not work with my BuWizz app and instead of being a servo it spun around in circles slowly then I put in a real Lego servo And that worked well but then my 2 BuWizz motors were on one of the PF ports they spun in different directions therefore it did not work could I please get help

    • Tihomir

      Yes. Please send your request to support@buwizz.com, and our technician will help you.

  3. Marek

    Buwizz is a great opportunity to upgrade your builds but one of my buwizz broke after i put it under heavy load. I ran two buwizz motors on it and it just broke.

  4. Bricklab2006

    I am very glad to own a Buwizz!
    The main reason is the size, wich makes it possible to build even smaller creations with fewer motors, of course the capacity could be better, but I think due to the size it wouldn’t be possible.
    According to that I have one question: are you planning to develope external batterie units?

  5. TechnicGuy303

    I think the BuWizz is really awesome, but you gotta know, that if your turbo-charged rc car drives into a wall, the car is broken and you might have to replace some parts.
    So use it (Its just EPIC !!! ) but be careful ! ; )

  6. MIKKO08

    Great, my rc mobile cargo vehicle needed some form of powerful motor, but buwizz just made the m motors strongrr. I am wondering if i can connect a non-buwizz fpv camera

    • Tihomir

      Hello. Basically, we revived the late RC buggy motor and made it a little more powerful. We tried more than 30 cameras, and just BuWizz (Eken) and Apeman sports cameras have the same RTSP link. The BuWizz App offers you to change the RTSP link and connect any camera. You just need to find out the RTSP file from the manufacturer. Good luck with that 😉 They mostly don’t know what are you talking about. GoPro doesn’t offer this.

  7. MIKKO08

    Fantastic, after an year of a bit of abuse still works nice, the only thing i need to know is if i can use any non-buwizz fpv cameraa

  8. Snoopy brix

    Absolutely stunningly powerful! Would recommend to anyone who is tired of the lack of power standard LEGO power packs provide.

  9. Mees

    I think it’s a great battery but now all of a sudden when I charge it, it blinks slowly and when I connect quickly get it now no longer off.
    greetings Mees.

  10. Andy

    Received faulty unit,stellar customer service,replaced ultra quick.
    Stunning product and easy to build in nd use.
    A1 all round many thanks Buwizz

  11. Gerrit Jansen

    I am like BuWizz is super cool

  12. Gerrit Jansen

    this is super cool

  13. Robert Barrett

    Absolutely awesome!
    I would recommend BuWizz to everyone who wants more power for their LEGO creations.

  14. Newest_Tech320 (verified owner)

    The BuWizz is great. The only thing I would have liked was for the Buwizz to be 9 studs long instead of 8 because Lego technic has odd numbers not even numbers.

  15. Michal Krcho

    This thing changed my life! It makes any fast car even faster and any crawler more powerful. Now I can’t even imagine going back to the IR system. My fastest MOC was a Formula with 2x BuWizz and 2x Buggy motor with top speed about 25 km/h (15.5 mph) and I wasn’t even trying to make it that fast.

  16. Gamemasterks

    Every Technic RC MOC builder should get this! It provides way more voltage than another of the other rechargeable solutions on the market. This will reignite your love for Lego RC cars in a way nothing else has before because of how fast this will make your Lego RC car go! This with RC Buggy Motors makes a killer Lego RC car! Also since it’s rechargeable, it won’t burn a hole in your wallet because you don’t need to constantly buy new disposable batteries. It’s also bluetooth so you can actually use it outside without interference unlike Lego IR. The app is also nice with very customizable controls and very interesting programming features such as power curves which are able to solve a lot. The price is absolutely worth it for what you’re getting which is a high performance, compact, rechargeable battery box.

  17. Philipp Hasler

    Genial alles klappt

    Best remotable brick ever. Great power and very long battery life.

  21. Ming Ying Cai

    With BuWizz, your tech Lego is wonderful, if you do n’t have it, you ’ll lose color

  22. EM4N

    I have to be honest, I was looking for a powerful and compact solution for moving my tank, then I found BuWizz. This is far away from any other solution because of its light weight, the outstanding capacity of keeping the charge and of course the integrated 4-speed circuit, without any need of external gearbox. I am planning to buy more in the future, I recommend it.

  23. Charlie

    I think it is a great power source, but when I emergently stop, my model is doesn’t, and it crashes. Also, right now, I can’t figure out how to turn this buwizz off. It keeps slowly blinking, and no matter what I do, Ex: charge press it, it acts like that I never did anything to it, so I left it uncharged and overnight and in the morning I saw it still blinking.

    Simplesmente magnífico

    Très bien , rapide…

  27. yumingqin

    Bu is a very special product in lego moc

  28. Charlie

    Great! Fast speed needs fewer motors. I am just wondering if the buwizz can overcharge

    • zerobricks


      BuWizz has an integrated charging circuit, so it can’t overcharge.

      Best regards

  29. John F. Hildebrand (verified owner)

    I bought one to see how they perform. I bought two more because they did everything that I hope they would.. Some unit I built much too slow,barely work. With buwizz now work perfectly. Will be buying more.

  30. clansmenator (verified owner)

    I have been using BuWizz for over a year now and it’s freaking awesome.

  31. Gaidis (verified owner)

    Power unit is really powerful, and with good range :), can’t wait controller support, would love to see option to use it as battery only, so I can use IR control for kids.. but got hanged up hope support will help me to get back and running, but camera is oposite :(, range is poor ;( , if we could conect to wifi router with it I guess range would extend(now it works as his own access point only, most kids won’t manage to start by themselves), but now in straight wisibility is ok, but next room signal too poor.. So you can’t drive around house and see what everyone is doing.. So camera is like useless fancy thing.. 🙁 Battery time while streaming is also quite short.. Not included mount for Lego, and doesn’t have even threaded camera mount, bit complicated to fix in place

    • zerobricks


      We are glad you are happy with the range and power of BuWizz.

      Regarding Wi-Fi camera, here are a few suggestions:
      – Turn off any devices which may intefere with communcation of the cmaera such as open networks and such
      – You can extend the life of the camera by using a simple powerbank
      – For casing you can build a brick case like this:

  33. Racing Brick

    BuWizz is a unique way to power and control your LEGO creations. One benefit is the size, the battery and the controller is packed in a box that is smaller than the LEGO PF AAA battery box alone and it still has 4 Power Functions connectors. The other benefit is the extra power it can provide, with the higher voltage options the Power Functions motors will be faster and stronger. The app clean and straightforward to use.

  34. BLEICHER Serge (verified owner)

    BuWizz est actuellement le meilleur produit pour commander nos lego motorisé. BuWizz a le meilleur rapport qualité-prix du marché. BuWizz est le plus puissant tout en étant le plus compact. Il y a toujours une réponse positive pour toutes les interrogations, remarques et critiques concernant BuWizz.

  35. The Brick Wall

    The life of a creator before and after using the BuWizz.

    Looking back at my first projects, I wonder how easy it would be to control them if I only had one Buwizz brick. My typical creations most of the time are complex in nature and use more than 10 Lego PF motors. Some of them need to be grouped together, others need to be controlled independently and the rest need to be pushed to the limit. In fact, I push the limit in every one of my projects. It is so much fun. When I start working on a new project, I know BuWizz will give me the control, the flexibility and the precision required to operate my machines.

    It is impressive how the BuWizz Team packed so many useful features and kept a friendly user interface. And most importantly, the Team is listening for feedback and suggestions. Well done.
    Purchasing BUWizz bricks was my best investment.

  36. Will Hoth Bricks

    Excellent produit qui permet à des modèles déjà motorisés à l’aide du système Power Functions de bénéficier des avantages “modernes” proposés par la brique Buwizz : Bluetooth, batterie rechargeable etc…

    Interface de paramétrage simple et accessible à tous, application stable et fonctionnelle, Buwizz donne vraiment une seconde vie à de nombreux produits interactifs sans nécessiter de connaissances particulières et sans devoir intégrer de nombreux composants et câbles additionnels.

  37. Marxpek. Holland, age 35.

    Buwizz is THE way to power buggy motors. Fast and easy in use. The best option to make your lego RC.

  38. Jan Baan (jbb_777)

    I needed to power my elevator. A normal LEGO battery box was hopelessly insufficient. With Buwizz it worked like a charm. Additional advantage is that Buwizz is 100% hidden thanks to the bluetooth connection. Regular LEGO remotes require a visible IR receiver.

    Check out https://www.instagram.com/p/BrOVhInHppk/?igshid=12wofoc26r6b to see how well Buwizz is able to move my elevator ????????

  39. András Borsos

    The application is quite straightforward to use, it has all the necessary controller types and some additional smart features such as steering for tracked vehicles, power curves to customize the effect of controllers to outputs and live camera streaming.
    The power is incredible, Fast and Ludicrous modes boost up the speed of creations to a whole new level. It can power my old 9V motors, PF and RC motors as well.
    It takes up just a tiny space and it can be charged with any kind of mini USB cable, even from a powerbank.

  40. All About Lego

    BuWizz is definitely a huge step up from the standard Lego power functions system. The first benefit is that BuWizz can be controlled using Bluetooth from an intuitive app on your phone (which allows you to create fully customisable control panels) – much better than the IR remotes that are used within the Power Functions system as it isn’t affected by the sun – meaning that the range you can control your Lego from both inside and outside is great! It also has 4 speed modes – slow, normal, fast, and LUDICROUS, (which really is ludicrous!) compared to just the one that Power Functions has. I must admit that at first I thought the price seemed a bit steep, but when you consider what you are actually getting for your money – the equivalent of a power Functions rechargeable Battery box, two IR receivers, two IR remotes, (and the obvious extras of the app, Bluetooth control, and different speed modes etc…), which aren’t exactly cheap themselves. And to top it all off, BuWizz is even smaller than a Power Functions AAA battery box! In my opinion, this is an awesome product which adds so much to your RC Lego Creations!

    Can’t believe how easy buwizz moves my newest moc. Its heavy and moves well.
