Thank

Hi! I am Gilly and I am also following you. I want to ask you if it's possible to update the firmware of the new sciwil lcd sw-m58? I baught it with the tsdz8. Thanks for your great job.

I did something similar to my sabvoton build. but what i did change was that i nerfed my phase amps a lot rather than battery amps. before i had great acceleration and could go up any hill but my controller was hammering my battery at any speeds. after i lowered phase amps it uses a lot less battery at lower speeds but i still have decent mid t high end power and speed. it moves pretty slowly from a standstill or going uphill at low speeds but then thats countered by pedalling through it. I almost doubled my range on my route to work (its an offroad footpath with about 0.5 miles of road at the end)

We need to know how to DO wheelies and go FASTER!

Hi luke. Do you know where i can get a adaptor cable from so I can change my vlcd5 to a ekd01 or the 860c? All the 1-4 8pin cables seem to have the male 8pin not female

I replaced my 500 W TSDZ2 with a 48 V 750 W TSDZ8 more than 2000 km ago. I use it mainly for commuting to work, which is about 15 km each-way with a couple of small (50 m) hills. I LOVE IT! It is much, much smoother and has oodles more power. In fact, I only use it at a power setting of 3 from a possible maximum of 5 to stop it being too fast. The mounting is good, although it did need to be re-tightened a bit at the 1000 mile (~1600 km) service that I gave the bike. I took the throttle off as I was not using it :)

Is it possible to somehow make it work with EKD01 display?

Hello i wonder how could you add throttle i couldnt add i bought but it wont work

I like simplicity. I did not like cables and display. Is it possible to use TSDZ8 without display, speed cable, throttle etc? This is my plan: I build this system with everything. I choose level of assistance. Then, I remove everything except motor and battery. Since, motor works when i press to pedals. It seems it can work with only battery. Is this possible? Thank you in advance.

I have installed 2 Bafang 750 mid drive kits now and neither of them have EVER made my bike wheelie or go out of control. Recently I detuned both bikes to more gradually deliver power on the onset of peddling. Mostly to lessen the feel of the assist. But, not for the over dramatized wheelie or out of control thing. Not even on setting 9 will they do wheelies. You have the 42 tooth front sprocket? If you do, and this is probably why you are doing wheelies. Most riders should be using 52t front sprockets as the smaller sprockets are for mountain bike set-ups.

Both my bikes stop motor support within a tenth of a second when I stop pedaling. This usually is enought. But on the mid drive bike I installed one on the rear break lever anyway becaus in lower gears the motor might be hard to stop if something goes wrong. On my rear direct drive bike I'm perfectly happy without break switch, but I installed a seperate switch to start recuperation manually if I go down a long hill.

Why is the vodeo/sound breaks every couple of seconds?

Got a bafang bbshd and 500c display is powers up but nothing happens but a quick blip when you hit throttle and then nothing

Esperienza personale batteria lifePO4 + Caricatore dedicato BS messa su bmw gs 1200. Superato il primo anno a fatica ,il secondo anno KO. In inverno impossibile avviare il boxer. Bisognava ridare tutto indietro ma non ne avevo voglia...Buttato tutto e rimontato batteria normale sl piombo. Non all'altezza😢

I didn't get keys with mine, i can't believe this, I'm so annoyed ?

Thanks I came here to learn how to slow my 750W down! Its too fast for the commute and I dont want to break local laws, plus I want to keep everyone safe. I like the idea of extended life for all parts, great thinking!

I really like to get this motor, but this 44t is juat soo big and I want to use the bike for some MTB....but this 44t is really a deal breaker. Unfortunatelly no other chainwheels are available ...and with this strange design I doubt theree will be. Any clue in this regard ? Thanks for your efforts.

Nice review, it would be nice to show us the Q-Factor on cranks. Is it worth than the TSDZ2B ?

Why not The ToSeven DM02 of 01 (I have only installed a few so far, but I have been impressed)? TS messed up factory programming on their TSDZ2, but there was a time when its lightweight and torque sensing made it ideal for most of my customers (installed a gross of them). My experience with OSF has been disastrous. Bafang requires so much extra wiring, it is heavy and their antique chips make it slow to respond to cut-offs. I don't have any customers willing to invest in The CYC Photon though I hear it has come a long way from the initial problems that scared me away. Would really like to see a comparison between The 8 and both The TwoSeven motors (Bafang and CYC programming right at the display). While I have been impressed, I have only seen reviews by wholesalers.

In the settings you change the A? what does this exactly? In the manual is says: Assist ratio setting, what happens when you max it to 36 or put it on the minimum 6?

Hello. Nice to see You again.I installed this motor on my hardtail Canyon Grand Canyon AM bike . But with EKD01 display. And SRAM GX11s deraullier and shifter and e*thirteen 9-46 cassette. Runs great.

I bought mine in November last year, since TSDZ2B could not fit my bike, hitting the chainstay. TSDZ8 is more compact in the main gear part, similar as BBS02. This moror is a beast, I rode it near unlocked Haibike Almtn8 uphill and tsdz ate it for the brakfast. I did 50km MTB uphill rides on 35 degrees celsius outside, it never overheated. BTW, polish firmware downloadable from Ebikestuff,eu blog is the best for me. I tried several firmwares

Your previous videos had always inspired me and I wanted to try to build a bike too. I waited years... I was intrigued by the torque sensor, but the reviews of the Tsdz2/b had never convinced me. At the beginning of the summer I saw this new Tsdz8 model. I bought it and mounted it on a riverside 500. Apart from the first level of assistance, which is too weak, I find that the engine works very well and with a 13ah battery the km range is impressive . Now I hope sooner or later you will make a guide to update the firmware. Thanks @LukeLorusso for the inspiration.

Luke, thank you for your video. I am interested in a setup that would be good for long distance riding. Something that can go over 100km distance if possible, even on a hilly terrain. I would like to have the natural feeling of riding, but I would also like to have the option to adjust the assistance when I get tired. Which motor and setup would you recommend ? I suppose the best way is to try different setups and see which one feels the best, but for some reason nobody is riding mid-drive ebikes, at least not the ones that are assembled.

Thanks for your video. I just installed this motor myself on my old bike and WOW ! It is awesome! The torque sensor is really great and feels natural when pedalling. It's also very quiet, you can barely hear it when riding. Of course if you just want to use throttle or casually ghost pedal, it's not the right choice, but I wanted something that still feels like a normal bike and this is it! As for the TSDZ8 tuning, I have no experience with the TSDZ2, but it feels ok. I have the EKD01 display and level 1 and 2 are useless in my opinion, but starting from level 3, the assist is really great. Throttle is also ok in my opinion. It's true that it's a bit slow to start, but ramps up fairly quickly. Finally, custom firmware seems to be on the way for this motor. No real OSF yet, but the possibility is there, so I guess it's just a matter of time. Here is some info: ebikestuff.eu/en/content/18-tsdz8-firmware-update-using-j-link-jlink-v9-programming-kit?fbclid=IwY2xjawFLuI5leHRuA2FlbQIxMAABHfxKZW-KCxQ3gGm0IAUCASV_WeSqPU1YQS2d3OvBiAs817GTqzbfY3S2nw_aem_sH45l_EHJq2KMvQwlSSqjg

Hi Luke. I'm waiting for your assessment of the motor as I always found your videos very informative. I'm surprised with your comments about the throttle as, you may have the oldest firmware version on it. I watched some other reviews where it was mentioned an improvement with some later firmware. Also to the motor responses are better tuned but for what I heard they are still not 100% there. The good news here is that Tongsheng seems to be supporting the community and releasing new firmwares with mods suggested.

Tsdz2 rider here, been riding it for couple of thousand km's so far. You're 100% correct on the fatigue part, I even got knee pains during multiple rides because of the power needed for my legs to activate the motor assistance. Turned out my torque sensor was badly calibrated. Installing open source firmware and calibrating the sensor with them transformed the bike for me. Now, I can ride in assist level two without feeling I would be better of on a normal bike, let alone level 3 and 4. Still also not entirely happy with the clutch system, with the motor off it's so much harder to pedal then say a shimano mt200 with torque sensor when turned of. That surely can't be good for efficiency, I should consider trying to replace that clutch to see if it improves.

Just got the 750w 48v for my Gary Fisher Tiburon with the 500c display. My first ebike & its for reliable transportation so I'm going to shift as much as possible for efficiency. I got a Samsung 30AH battery so I should be ok for long occasional 35 mile trips. Also 2-10 mile grocery trips with my new bike trailer. I was worried the 500w wouldn't pull a full trailer well even in low gears.

I have the BBS02 750w. Thank you for making this. I dont like pedal assist. I just want 100% throttle on PAS 0. I can do that or set the throttle menu 'designated assist level' to something other than "designated by command". I live in Detroit and will be using this to haul groceries home in a bike trailer. So I know this is needed. Thank you sir!

Grazie per il video anche se i passaggi sul PC sono troppo veloci e poco chiari. In ogni caso la procedura non sempre funziona. A mio avviso ancora la procedura è da perfezionare.

Hi there, i wanted to make my motor to be used by throttle only and disabled PAS in the programm. However I still get the 21H error, do you know how to get rid of it?

I have a 750w kit. The big problem with this engine is overheating which prevents the engine from reaching maximum performance. I made some changes following the instructions in some videos and installing aluminum heat sinks. The situation has improved but during the hot season I will never get 100% of the performance. I don't think that installing this firmware will have any advantages as the main problem with the tsdz2 is due to a mechanical design defect.

Merhaba, ben üç tekerli bisikletim için almak istiyorum, yaşadığım yerde yokuşlar var, arka sepette iki çocuk taşımak istiyorum sizce tongshengmi, bafangmı tercih etmeliyim?

Your videos made me decide to buy a TSDZ2B, thanks! About the throttle, since you're only getting half the input, did you check the voltage your throttle is outputting? If you have a bench PSU you can try using it to see if higher voltages return the desired bit value. The usual voltage range for ebike throttles is 1.2v to 3.6v (some are 4.2v). Hope this helps! Thanks

if you live somewhere in the south of Italy or Spain - yes, maybe you don't need a car. and for example, in Poland or Ukraine, we have 3-4 months of winter (+3С...-10С) - you can get sick on a bicycle (or even killyourself on the ice). also, in October for exampe, when the temperature is +8 or +10 and it rains all day - I look like a fool on the bike...

good build! it's more important to me that the bike is light and good-handled, than that it will have a speed of 50 instead of 45, or will accelerate to 45 not in 8 seconds, but in 7. also light battery of 13 amp-h is also enough, just enough for the city. charged in 2 hours and you are ready again. and a large 20 amp battery - will never be fully discharged and you just always carry extra weight with you.

I now use my car only when my tsdz2 bike is broken. Unfortunately, heavy and sudden rains are the real enemy for this engine. The battery must be protected from water. Congratulations for your videos.

I have standard brake on my e bike i Need the sensor or not?

DAMN !!!! Super !!!

Hi, this working with tsdz2b with 500c display?

How do you pull the brake lever (so that the motor disengages) and not actually brake though?

I have an EDK01 display, can I install the OSF?

I have set up the bbs02b on over 20 bikes.. The b at the end of bbso2B signifies the later controller that has PAS set as priority over the throttle.. The old bsbo2 had throttle priority over PAS.. This is why the bbso2b sucks balls.. When the system detects you turning the crack aka pedalling the throttle is disabled... WAIT! You will say no its not, it still works loser.. Yes it still works but only if you twist it to 100% anything less than full throttle is ignored.. Now.. The best way to set this controller up is CUT THE GREY PAS WIRE!! Get rid of the useless PAS,, the pedals are there for your leg power and should not be a system to add power to a bike,,, maybe on a 250w but that's it,, Make your bike throttle only!! You ride your bike like a bike man, then you twist in some VARIABLE POWER with the twist throttle or thumb throttle,,, NOW READ ON... You controller is 25amps right,, you PAS 1-3 or 1-5 or 1-9 depending on your display settings.. Set it to 1-9,, NOW what happens if it's on PAS 1 smart guy?? Then your throttle will have a variable sweep from 0 to 100% of around 3amps.. You can use that to just barely add power say after a long ride you need to get home and you just tap in a bit of power as you go,,, PAS 2 will be like 5amps PAS 3 say 7amps and so on.. You get the idea,, if you put PAS on 9 your throttle will be a variable controller from 0 to 100% of 25amps... You would be surprised on how little power you need to have fun.. In PAS 6 with you pumping the pedals as soon as you add some throttle ya jump to 35km right away.. You can simply click the PAS number up or down depending on your riding conditions and adjust the amps available to the throttle as you ride,... Your bike will feel so much more natural you won't ever want PAS again... Your drive will last way longer and your range will jump by 30%.. I've put over 25,000 km on a bbso2b and pulled it apart and it's still perfect, you just regrease it and maybe a bearing or 2... I could go more into the controller programing but you can research that... Look up "cut the grey PAS wire"

can i use 48v battery in bafang bbs 01 36v?

Thank You. Because of your video I trusted that website and downloaded the program. The program works fine on my computer! So now I am confident to try it with the cable!!!

Cry baby, I have the 1000 watt and love it. If you're geared very high I can see the torque being crazy but 46 tooth in front and 26 in back isn't wheelie ville. If you want a torque sensing get the m365 mid drive. Geesh

Top speed in this video?

Very helpful video, thanks! One question, though, I see here, and in other BBSTool videos for the Bafang 750w mid drive motors, the 100% current limit is at around 24A, with 48v battery, this is just over 1100W... no issue with this!? Why not reduce the limit to 16A and protect the motor?

The speed limiter isnt power efficient. If 10% current can give you 20km but you limit it to 10km your wasting 50% power.

It'll overheat and die on you sooner than you think. Its a great motor once you put some heatsinks on it, outside of this its barely adequate as obviously, a dead motor isn't much use. I'd go as far as to say it's almost fraudulent the state in wihch this motor is sold given the serious heat issues it has. Other niggling issues such as premature clutch failure, and otherwise poor quality components (for example, the pedal axle is known to crack and snap) really let this motor down. Extra modifications such as adding bearings and shims can help, but ultimately what it needs is better made components. For the average ebiker/non-tinkerer, this motor is absolutely not suitable. In spite of this, i love the OSF aspect of it and for that reason alone i'm very fond of my TSDZ2(B). Particularly in an economy/society whereby manufacturers are "software locking" down everything behind paywalls and extortionate fees.
