Ordered the parts yesterday! Very keen for my 52v setup. I really need the button for the lights to work, but my guess is that by the time the parts arrive in AU it might be done! Thx for the great videos.
Great Work,, just got this working today. Far better setup than the stock, looking forward to extracting the best out of the system. Building a big 52V battery for a couple of leaning trikes at the moment, be interesting how the new setup compares to the 48V hub motor from factory.
Hola, me ha gustado mucho este video y seguire viendo constantemente tu canal, es lo qu estaba buscando para confirmamr mi teoria, porque lo venden con diferentes potencias y el tamaño no varia ni apenas varia el precio. Thanks you
Thank you for this video! I will be ordering the 750w 48v kit soon. Will the firmware work with the lcd5 or do I need to order an lcd3? Will the lcd3 work with the newer controller? Does this firmware work only with the 6pin or with the 8 pin lcd3 also? I am not going to use a throttle because the rules in Oregon would limit my speed too much if I do but I would like to maintain the option for resale value. I will let it go if I need to, I want to use this firmware.
I have the Gen 1 Bosch 50 Nm and stock firmware TSDZ2, the Bosch is more powerful and runs cool all the time, the TSDZ2 gets very hot. The rating of 80 Nm out of the box is and absolute lie, it's more like 40 Nm. The only issue with the bosch is the 27/28 Km/hr cut off, so on level ground the TSDZ2 is faster but where I need it the most the TSDZ2 can't deliver the goods. I can't imagine the open firmware will gain 30-40 Nm ?
Great video. In an older video, you said the Trek Powerfly was just so much smoother. After the firmware upgrade, how much "smoother" is the TSDZ2? Has it closed the gap to the smoothness (and analog bike feel) of the Powerfly?
It’s much better if you didn’t ride the trek then you would be very happy much nicer than stock but when you have both there is no comparison. Ignorance is bliss ;)
Jbalatutube: Hi, I really appreciate all the information you are passing on. I am dying to try this but I have not yet purchased the motor because I can't find good info to decide between 36v and 48v versions. My principle goal is to go up long steep mountain roads, and I am almost 200lbs. (88 kgs). I have a few 36v batteries now, so I am leaning towards the 36v edition, but I don't want to buy the wrong one. I listened to most of your videos and know about the 90rpm cadence limit of the stock firmware, and the way the open source removes that limit. If you know, are the 36v and 48v the same except for firmware? Does the 48v version use different windings to handle more watts or a different KV rating. That is different number of RPM per volt. Is the controller on the 48v able to handle more watts. Perhaps it has larger capacity or more mosfets. If you know great or could point me to where to find this it would be most helpful.
You also enjoy riding an awesome Trek Powerfly 5FS bike with Bosch CX engine. I wonder how the TSDZ2 with Open source firmware compares to the mighty Bosch CX engine?
in your opinion would you opt for 52v or 48? Also, any recommendation on seller for this product? Do you recommend throttle or is the torque sensing accurate enough with this firmware to be apt at climbing hills? thanks! and thanks for the vid!
Hi Matt please explain about the green plug. Unfortunately I had to cut the plug from my ktlcd3 and use a plug from a speedo splitter cable. You could just cut off both sides and splice together up to you. Please see the wiki for wiring instructions or watch some of my older videos.
@@jbalatutube how much distance can you get from 10ah battery? I have a bike with an 8.8ah battery built in. Will I notice a greater milage compared to the 250w hub motor that it came with?
@@Jonmc511 between 40 and 50km depending how hard I ride. If you mean whether it's more efficient then probably yes but would not be a great deal maybe 5%
Hi, is it possible to upgrade the firmware, tweak the motor with th lcd 3 just the way I like and then use the xh18 display with the modded motor settings?I would really like to keep my bike very with the smal xh18 LCD. Thanks for your reply!
Whatever you want however be aware that the motor can heat up quite quick with a lot of Amps. The new firmware now has temperature throttling to keep the motor cool. I have purchased the LM35 sensor and will be installing it soon
hi. Thanks for your videos. I have sifted through the information and read some of casainho's literature. I am wanting to ditch my speedo sensor but am worried it will affect output calibration. If this valid, or is motor output only calibrated via torque sensor? Thanks for any insight!
Is it true that you can only get higher cadence (above 90 rpms) when running in 36V mode? It would be nice to have higher cadence features with a normal setting on a 52V or even 48V setup (motor and battery) so the speedometer isn't off. Is this possible?
I bought a tdz2 on the strength of your early reveiw, I wondered does the firmware make the bike anymore like a Bosch motor interns of smoothness / acceleration
Hi Chris please ride the bike with the stock firmware first just to make re everything is working fine with the motor. Yes the firmware gives a huge performance boost similar to bosch but the motor is loud and not smooth like the bosch. The advantage is that you can tune the amount of assist to suit your riding style, I find that I am always sweaty when I ride my bosch because the assist level is not right for commuting but more suited for mountain biking.
I've been reading very mixed reviews of the TSDZ2. at first seeing the blue wheel was one of the only downsides for fixing. How has reliability been for you?
Onoff314 i have done more than 15,000 kms. I did replace the blue gear and sprag clutch but besides that it’s been very reliable. Would definitely recommend it.
@@jbalatutube That's good to hear, that is the kind of KM i would like to get out of mine (when i get it). Just wondering i see you have the LT3 screen and some forum posts i see they are moving to the Bafang colour screen. Is your screen supported moving forward or are you happy with your current firmware?
@@onoff314 not supported going forwards which is a shame stuck on 20beta1 which i love. It does everything I want it to do and there are still some people tinkering with this version in the background. It would have to be something really awesome for me to change over to the colour display.
@@jbalatutube Yeah i'm not all about the colour display either. Would rather keep the bike less fancy so people don't try steal things off it if i ever need to leave it outside for a bit. Thanks for the info
@@jbalatutube i have the sondors bike thin edition. With the same display I believe... But not the same futures?! So how can I fix this, how can I get in these modes that I can change power ... and direct motion?! Thanks a lot! Biy the way great videos 🙏🏼👌🏼✊🏼
@@iamkaifulify The Sonders thin uses a different motor and controller. The Open source firmware that is running here has been adapted to use the LCD3 display, which appears to be the same as your Sonders bike uses. Although they are the same, the firmware here is tailored to the TSDZ2 so is not a drop in replacement for the sonders hub motor controller. That said, if you research further, you will find out that this firmware was based on an older open source ebike firmware project. The older project also had Cashainho as a lead developer. By this I am suggesting that with some work, you may find there is open source software for your Sonders. But that is just an educated hunch.
Sky man ok there are different versions of the firmware now. The one here that I use goes to version 20 beta 1 which runs on a ktlcd3 display. Marco has ported this to run on the standard displays however it can’t give you any of the data and the settings must be done using a Java app. Casainho has continued on his own to use the colour 850 display and the small sw102 display, it is not as good as the 20 beta 1 as yet but it is currently the only branch being developed so it will be getting better. Anyway more info on endless sphere tsdz2 threads.
@@jbalatutube hood to know. I am looking ad the e-assist gor my recumbent Trike that I am building. This e-assist seems to be good for the price. The blue gear seems to be the biggest weakness and that is easy to fix and replace with an other one. Now I also noticed that there is other firmware, but I don't know if it is something that would work for me. I want to ride long distances and not really high speeds. I have a 9gear ad the rear and currently a 3 gear in front, but that will be replaced by the e-assist. I don't need a high cadance, so I don't know if that is something for me, but more power and a longer range is something I like, because it needs to pull more weight. But I must look into it as I have the e-assist. I ho for 250w because of the rules out here. Don't want to have a licence plate and don't want yo wear a helmet. Also I don't need to go 45km/h. I will personally stay under 20km/h.
@@jbalatutube will it be safe on the battery? The motor will not destroy the cells? No need to physically keep an eye on your battery voltage because of the battery but off?
Unfortunately too much hassle to get this new firmware... Waiting for an official one from Tongsheng to upload on the VLCD5. I might wait long I guess :)
Real ebike companies have R&D and update their motors and firmware every year. Chinese kit makers design their firmware once then forget about it. I think you'll be waiting forever.
He has been working on the 850 color display so all development has stopped for a while. That being said version 16 is really good and has the high cadence option for 36v motors. Not sure how much better it will be with variable FOC until we try
Hi what are safe settings for not overheat ? I Have the 750w 48V 24ah and i wanna modifi the software with high cadence and 12Amp and Max 500Watt what you think. I go often Turbo and Climbing
i have found that continous use above 220w will raise the temperature. Occasional use over 500w is fine. generally when I ride it fluctuates between 90w and 250w its more if you are staying over 300w all the time that you will have issues

Hii so if I get it right your building your own battery... are there videos of how to do that?
Thanks you made me curious!
BIG THANKS!! Great contributions you are doing!! and so lovely day outside, that is exactly the objective of all this technology :-)
Thanks Casainho, but without you there would be no firmware. Appreciate all your hard work :)
Thanks for that great review. As we head into winter here I'm hoping to find time to give the firmware a go.
John Schofield Thank you, you better hurry.. it’s cold here now but a bit of sun now and again to get some testing done
14S is for 52V and 13S for 48V.
