I also run a BBS 02 on 52v with a ASI BAC855 sinewave controller it's awesome a different animal to the standard Bafang controllers 750 or 1000w I would never go back to the standard controller now .
My BBS02 came configured for 48v battery at 24 amps. Full throttle does 1152 watts. It is rated for 750 watts. It will do the 1152 watts, but it gets hot, really hot. You can fry an egg in it hot. So if you have a BBS02, get a communication USB cable and configure your controller in a way that wont burn you motor or controller.
I just got a bbs02 to test, how were you riding to get it that hot? whats is uphill, on flat, bad gear ratio?. When I ride my bbshd as hard as possible it only gets to around 45 Celcius on the outer case with a 54v fully charged to 61.5v I get around 1600w out of the bbshd with stock controller.
@@gerardr4869 Really? I have a BBSHD and I commute daily about 80Km (40Km one way). Even if i drive constantly with 600-800W (nearly 1600W while accelerating for a few seconds, then only holding the speed) the motor gets into thermal throttling after neary 1 hour. The heat inside the motor builds up very slowly, but it builds up. After one hour the heat is spread over the entire motor case and the controller tries to cool down. For a few moments I could only draw 500-600 Watts, then it ramps again up to max. So be careful, even the HD gets hot. Really slow, but it gets hot.
i run my BBS02 at 48V 18A, it's plenty powerful that way and there no issue whatsoever. I do have to say that I replace the grease on all gears with a silicone grease to which I add ample amounts of WS2 nanopowder and 1.6micron PTFE powder as dry film lubricants. Also I put some silicone sealant everywhere water and dirt could potentially ingress. The BBS02 is much better suited for mountainbiking because of the thinner final gear reduction (perfect chainline on 36t chainring with some cassette adaptations) and the lower weight. People are complaining that the BBS02 is heavy compared to an frame integrated motor, but all the weight gains are compensated by the lightweigt nature of tubular bike frames (rather than heavy shells of integrated motor and battery ebikes..). The last build for a customer gave a bike weight of 19.7kg with a 650Wh battery. that's very lightweigt!
Good points on the application of the BBS02 to mountain biking. Do you know if it can be successfullyl adapted to a mountain bike that runs a 1x12 Shimano SLX/Deore chain set ? I am contemplating converting a Marin Rift Zone 27.5" (73 mm BSA bottom bracket and stock 32 tooth front sprocket). In particular, I thought that I read somewhere that the 1x12 uses a narrower than standard chain which, if true, could presumably present a compatibility with the BBS02 sprocket. But I know next to nothing about these things. Hence the question.
@@kshred3043 honestly I would not go for anything more than a 10 speed cassette. The reason is pretty simple: 11 and 12 speed cassettes are wider than 10 or 9 speed. that automatically means more torsion on the chain in extreme cogs which wears down the chain, chainring and cogs more rapidly. I chose a 9 speed wide range cassette (11-50t) (only available from aliexpress as far as I know), along with a long cage 9s derailleur, and omitted the 11t cog to move the rest of the cassette to the outside. you need some sort of washer to enable the cassette lockring to push onto the 13t cog. 9 speed stuff is way cheaper and way more robust than 10s and certainly 11s or 12s. totally happy with 8 cogs and big jumps between them.
Was thinking to use an -02 for a spare/travel bike, due to the lighter weight. For regular use, will use the BBS-HD, as I’m needing to pull a trailer on a regular basis. Had one on the old bike - some wretch cut the chain last March while I was getting groceries…. They Got the bike *and* the trailer. Grrrr.
@@dennisyoung4631 the full power of the bbshd is reached beyond pedaling cadence, that's why I consider it more of a moped motor. it has a bigger rotor/stator and better cooling ability, do it can handle high power for longer than the bbs02. at 18A the bbs02 has no overheating issues, though. I pull trailers all the time, sometimes as heavy as 100kg even on uphills, not crazy uphills though. a weak point of the bbs02 is the not so hermetic plastic gear cover. I suspect it's responsible for a slow but steady loss of grease. Will be making a carbon fiber cover soon
@@JoLe1991 I went from 9s to 11s and now 12s. Honestly the 9s (XTR cassette, SRAM X9 derailleur and gripshit) is the best drive train I ever rode, way lighter system weight than any 11s or 12s. There are 2 things I like about 9s. 1) You feel the gear change (and the changes in cadence feel right) 2) If you're a gripshift type of guy the 9 sp gripshit racks through all the gears really fast with one relatively short twist of the wrist. With 11 and 12 you have to twist your wrist almost under the bar to rack the whole cassette or take 2 bites at it. I hate that. I had to go up 11s then 12s because of illness - I really needed the gear range especially in low gears. I'm looking at building an e-bike. With the power assist I won't need the 12s gear range. So I'm going back to a 9s when I build.
4:55 Technically, low gauge is a good thing. The lower the gauge, the thicker the wire and the lower the resistance. Historically, the gauge was a number of successively smaller holes the wire was drawn through during manufacture.
I always run a 30T-36T chain ring to keep the motor spinning faster.. that keeps the motor from lugging down which causes it to heat up.. Controller fail when they overheat.. they also consume less watts if they spin faster in a lower gear.. higher gear/slower spin eats up range.. The biggest problem i found with the BBS02 750 is that the Reduction Gear tends to loose teeth.. and they require a mechanic to replace the Reduction Gear.. You have to have expensive proprietary tools to remove the shaft from the 750w motor and special knowledge.. Very difficult repair. The BBSHD on the other hand is easy to change the shaft assembly with the new reduction gear.. Simple DIY project..
@Mustafa Hussein Hi Mustafa, my viepoint here is for offroad mountain biking, where speed is often not your friend. Is the HD better more speed more torque yes, but that is no advantage in offroad settings the 750w is in my view is all you need and is lighter. If your a speed freak on tarmac then the HD with high voltage 52v and higher, will.let.you yous.more.current which.means you.run your battery down quicker so a bigger.capacity eg 17ah battery......but then again there.are.lots.more faster addons em3ev.com/shop/50v-14s5p-rectangle-battery-pack/ Above is a link.to a.good.shop its.hong kong based so.you will.need.to.add import to.your.country. sorry for.all the dots im on my.phone and im not going.back over this lol. Good.luck
running my bbs02 750 at 18 amps 48v no problem for a couple of thousand km now. im a heavy person and the thing just works and gets me where i need to go. bbshd might be better but i dont own one.
unlike the bbshd, the bbs02 actually has a humane pedaling cadence(90-110rpm vs 130-150rpm). the hd is really more of a moped motor and the 02 is really a more powerful ebike motor.
I disagree. I have both and it's apples to oranges. Can't ride the 02 like the HD without frying controllers left and right. The HD also has longer fins to trap more air when you ride to cool it down.the 02's just get too hot and cannot handle it.
@@jasonkoz8985 sure the 02 is not made to be used at 25A. it can take 18A for quite a while though. The HD has more mass and more fins, and a bigger motor inside. I said the 02 is plenty robust enough for a reuglar ebike (like retail emtbs or s-pedelecs), the HD is beyond that category, I would say moped (as many 2 stroke motors have around 1.8hp). also my biggest worry of the entire drivetrain is not chain, not sprocket, but freehub mechanisms are thr weak link when exposed to such high torque (depends on motor torque and gear ratio between chainring and rear sprocket). the 02 is definitely able to shred up pawl freehubs, also the drive ring of dt ratchet gets beaten up...just to say thr hd is hitting even harder.
@@nigelnightmare4160 good point, pedaling beyond 110rpm is nearly impossible or certainly inefficient. hoewever, if you want to push 1300+ watts through a bike chain for extended time you need to increase the speed, not the torque
Why is there no option of keeping a double or triple chainring? I know that on upright bikes it causes chain line problems but on a recumbent bike/trike it doesn't because of the distance between the cranks and the rear wheel. A lot more recumbent trikes are now being converted than upright bikes.
I have both ,the bbs02 is a great little motor,but i found in the winter with snow on the ground it wuld throw a code and refuse to work.Yet the bbshd still works. Once the weather warmed up a bit it started to work perfectly.
The recon 60v is maximum the controler can handles so if you have 52v battery fully charged its very close to the limit,mine is 48v and runs pretty good and has plenty of go in it.Also it doesn't run the battery down as quick as the bbhd.
I have both and l'll take the HD any friggen day. The 02s are just crap. Gets too hot and frys the controller.ive been through 4 controllers and I will not be getting another that's just dumb.i don't ride it like my HD because it's just a cruiser bike and I was half throttle and pedalling when it happened to me last. Actually that was last night.lol I've beaten my HD to death and still performs like brand new and I'm not exaggerating.
You can overvolt bbs02b and go flat out on a flat road no problem. But then you must keep watch on the coil temperature and I mean physically the coil temp and not the shell since that says nothing, but it will be overheated anyway but you save the motor. I have put it at 75 degrees and it reach that in the summer in less than 30 seconds at 52V 20A, at winter and slightly above freezing about a minute. By not watching the temperature is a sure and very easy way to burn the coils in it.
The 02 runs like dream quiet and smooth with the BAC855 pure sinewave controller it's a different animal compared to the stock standard Bafang square wave controller
Love my bbshd, and won't be tempted by the 02 any time soon! ..like the solid over engineered feel, that and a 52v 17.5ah battery its perfect, if not strictly legal. .slapped a couple of 36v 250w stickers on and providing you're sensible ie power modes 1 and 15.5mph, should be ok.
Truth ,,, I have over 2200 Miles on my BBS02B 750 Watt with not one Issue !!! And I run it on a TerraTrike Rover that's over 75 lb .....!! With Stock controller set at 28Amps !!!
@@thomasjurd172 No I use 28 amps I was told by Luna the BBS02 (( B )) is set for 28 amps !! And with now 2,400,00 miles on my setup have not one Issue ..
The 02 also handles the HD controller from Luna at 30 amps ridden with common sense a simple job changing the the bullet connectors to Anderson type with a soldering iron ..
Regards the Bafang side mount motors. Why don't the motor controllers work with the throttles ?! I tried 2 from Ebay and one from Amazon. The Amazon pair- the throttle connector doesn't match the controller connector ! And the ebay's won't turn the motor ! The only one that did work is the one with the 100K pot. ! And it's quite possible what they promote here is phony too, making you buy extra stuff because stuff don't match !
the bbshd just looks...so illegal lol. which is good if you want to give the finger to a species that has imposed a 250w restriction on pushbikes, but that is not even talking about banning cars, even at this very late stage in our existence
I've run a 60v battery charged at 62v and there is a significant performance increase. It's a shame you can't get this battery specification anywhere. (55ish volts nominal).
you can use any brakes, as long as they are working good, even rim brakes lock the wheels pretty well to throw you over the handlebars. I used to go down mountains over 50 km/h and stoping with cheap rim brakes. The new stuff is trendy and most people want it.
good to know, 700 for the HD is painful ! it seems to have gone up another £50 since I got mine before christmas. Its hard to go back to the hub motors after using the mid drive, although I do feel that the same power of hub is faster in acceleration on flat or downhill.
I agree, I've a hybrid bike with a 500w front hub motor and it's a nice ride, even when comparing the bbshd monster on the other full suspension bike, both bikes I really like but have obviously different feels
Running 45000Km (nearly 28000 miles) now and still fine (daily commuting 80Km). I think in the near future I have to replace the nylon gear, but tha'ts pretty all of possible failure. The HD is made for the eternity if you drive with a bit o brain.exe and don#t try to squeeze the last watt out of it.
I've been running both at 52V, 25 amps on the BBS02 n 30 amps on the BBSHD. Both run tits at that voltage! I get 1300 watts outta the 750W motor...keep it lubed up n they do just fine.
I havent finished the video but outside of this video, theyre different things, the chainline as the name implies is the angle your chain is at from the front chainring to the rear cogs
Shame grin dont make external 25amp controller like they do for the bbshd. I blew a controller . After that i fitted a fish tank digital temp prob inside when fitting the new one
I run a BBS 02 on BAC855 controller on 60v 16s it's a different animal it smokes a standard HD it's almost silent and runs as smooth as silk .. without the weight of the HD .
the power leads on the 02 look like the ones on my TSDZ2 kit, and that was set at 16 amps when I got it.I still run it run it at the 48V@16A it came with from the dealer and whoo boy does it still get warm after a few miles. But even the BBS02 is twice what the TSD cost me, so I can't really complain about the fact I'll eat at least one controller and demagnetize the motor core at some point just because that drive is based on a 250W design. And to the TSD's credit, the thing isn't marketed as a high-performance motor. And did I hear your right about people running *1.6KW* through the HD? That's GASBIKE levels of power output. My nose smells failed electronics just thinking about it, lol
I'm riding on my second BBSO2 while the first is on its way to be repaired seven month less than 500 miles, do you mean I should have bought the BBSHD to ride to the grocery store and doctors? 5'7" 125lb where was this page a fortnight
None . Good luck as my controller blew but was commutein 16 miles each way and was doing 32 mph for long periods with no temp gauge . Now i put the digital fish tank mod in an can see when its getting hot
I have both and the HD all the way. The bbs02 controllers are pure garbage!! I've been through 4 now and I would never buy one again. It's going right in the trash on Thursday. Now my bbshd I've beaten it to death and it still operates like I pulled it out of the box this morning. I don't ride my bbs02 like the HD because it's a cruiser not a mountain bike and I've been easy on the throttle knowing they get red hot and fry controllers and yet still happened (last night actually) LMAO
You can fit the HD controller to the 02 they run fine I did it and I've now dumped the stock controller for the BAC855 the difference is like night and day and I run 16s (67v) smooth and almost silent..
They are great and tunable too with firmware but the lack of waterproofing is a problem. I figured a way around it, basically packing the gaps with heavy grease.
The pedal-assist feel on my TSDZ2 is nice, but the motor itself is a little weedy. On one side, that means it's not going to get impounded, on the other side, it overheats pretty easily.
Not as good as HD and would have gone the bbshd with more reshearch period . If the controller blows for instance you can allways go external controller route by buying a grin phaserunner plug and play and if your batterys a good one you can set it with phone app up to 50 amps and increase perfomance . The bbso2 is a great little motor ! If you do the digital temp probe into controller and hit the throttle not on full throttle to long . If mine gets to 45c or more l lower the ppwer an lay of the throttle . Best an only mod u can do with the 750w 48v . And can last if tode apopietley .
@@ricksanchez3628 yeah but I wanted home quick and had a 13 miles mainly on the road and flat ish, the next Monday morning I was just off to work and turn on an heard a small noise. Controller gone. I have a bbshd that just come from luna usa to uk and on picking up the HD god what a chunky motor.
what in the world is a quid? sounds painful...is it a number? a special coin? what is it? does it live in the ocean related to the squid? is a quid a female squid? i have zero reference here at all!
Can see why you can run 2000wat plus lol . Grin bac 800 bluetoothe set at 40 amps 2000 watts will do me . Thats my plan with 28ah 52v to go in my ruck sack. Cruse at 30 mph an 40 plus top end . Battery will cost more than the 300 pound motor . $420 is just over 330 sterlin

Ohhh that's what those stickers as are for!
I also have a BBSHD with a 52v 19.2ah battery and love it. I did have to reprogram it to be slower on the start up so no one would get hurt.
I have 1600w cable brakes, prefer them tbh just got to be set up properly. My sh1t stops on a dime no problem. Bbshd 30k plus
Truth ,,, I have over 2200 Miles on my BBS02B 750 Watt with not one Issue !!! And I run it on a TerraTrike Rover that's over 75 lb .....!! With Stock controller set at 28Amps !!!
28 amps dont you mean 25
@@thomasjurd172 No I use 28 amps I was told by Luna the BBS02 (( B )) is set for 28 amps !! And with now 2,400,00 miles on my setup have not one Issue ..
The 02 also handles the HD controller from Luna at 30 amps ridden with common sense a simple job changing the the bullet connectors to Anderson type with a soldering iron ..
Regards the Bafang side mount motors. Why don't the motor controllers work with the throttles ?! I tried 2 from Ebay and one from Amazon. The Amazon pair- the throttle connector doesn't match the controller connector ! And the ebay's won't turn the motor ! The only one that did work is the one with the 100K pot. ! And it's quite possible what they promote here is phony too, making you buy extra stuff because stuff don't match !
Does the BBS02 750W have a plastic casing and the lower voltage wire?
Which one would you recommend for a full mtb conversion for off road use
the bbshd just looks...so illegal lol. which is good if you want to give the finger to a species that has imposed a 250w restriction on pushbikes, but that is not even talking about banning cars, even at this very late stage in our existence
I've run a 60v battery charged at 62v and there is a significant performance increase. It's a shame you can't get this battery specification anywhere. (55ish volts nominal).
Wont that blown the controller
on what motor, the bbs02 750 w?
@@gerardr4869 yes
@@justbreakingballs no there is an error message at 63v or 64v and it won't let you use any power.
What's the idea behind you cannot have cable brake and a 1600w motor? Is it just because hydraulic brake have better brake power than cable?
you can use any brakes, as long as they are working good, even rim brakes lock the wheels pretty well to throw you over the handlebars. I used to go down mountains over 50 km/h and stoping with cheap rim brakes. The new stuff is trendy and most people want it.
bbs02, on 52v is better
Would it be ok if I use throttle only always ? Going 20mph or less always.
good to know, 700 for the HD is painful ! it seems to have gone up another £50 since I got mine before christmas. Its hard to go back to the hub motors after using the mid drive, although I do feel that the same power of hub is faster in acceleration on flat or downhill.
I agree, I've a hybrid bike with a 500w front hub motor and it's a nice ride, even when comparing the bbshd monster on the other full suspension bike, both bikes I really like but have obviously different feels
any more thoughts on HD vs 02?
Running 45000Km (nearly 28000 miles) now and still fine (daily commuting 80Km).
I think in the near future I have to replace the nylon gear, but tha'ts pretty all of possible failure.
The HD is made for the eternity if you drive with a bit o brain.exe and don#t try to squeeze the last watt out of it.
I've been running both at 52V, 25 amps on the BBS02 n 30 amps on the BBSHD. Both run tits at that voltage! I get 1300 watts outta the 750W motor...keep it lubed up n they do just fine.
Hey is the G320.750 the same as the .1000? Is the programming different or different controller?
Is "chainring offset" the same as "chainline?"
I havent finished the video but outside of this video, theyre different things, the chainline as the name implies is the angle your chain is at from the front chainring to the rear cogs
Shame grin dont make external 25amp controller like they do for the bbshd.
I blew a controller . After that i fitted a fish tank digital temp prob inside when fitting the new one
I run a BBS 02 on BAC855 controller on 60v 16s it's a different animal it smokes a standard HD it's almost silent and runs as smooth as silk .. without the weight of the HD .

@@thomasjurd172 what did you do to remove the heat problem at 35 mph?
@@gerardr4869bbso2 I wouldn't do long periods of time going 30 + but I have the bbshd with asi bac 855 50+ mph and done 2500 miles no problems
the power leads on the 02 look like the ones on my TSDZ2 kit, and that was set at 16 amps when I got it.I still run it run it at the 48V@16A it came with from the dealer and whoo boy does it still get warm after a few miles. But even the BBS02 is twice what the TSD cost me, so I can't really complain about the fact I'll eat at least one controller and demagnetize the motor core at some point just because that drive is based on a 250W design. And to the TSD's credit, the thing isn't marketed as a high-performance motor.
And did I hear your right about people running *1.6KW* through the HD? That's GASBIKE levels of power output. My nose smells failed electronics just thinking about it, lol
HD is far stronger than my 02, I for one will never go back
I'm riding on my second BBSO2 while the first is on its way to be repaired seven month less than 500 miles, do you mean I should have bought the BBSHD to ride to the grocery store and doctors? 5'7" 125lb where was this page a fortnight
No, you should have bought a bmw
Out over 1000 miles in my bbso2 with no issues
None . Good luck as my controller blew but was commutein 16 miles each way and was doing 32 mph for long periods with no temp gauge .
Now i put the digital fish tank mod in an can see when its getting hot
Hola, hay la posibilidad de recortar cables en especial el que va l monitor
can the controllers be swapped out from the HD to the 02/01?
Nope
Yes they can all you have to do is change the bullet connectors female spade connectors they run fine, they run even better on a BAC855 .

I have both and the HD all the way. The bbs02 controllers are pure garbage!! I've been through 4 now and I would never buy one again. It's going right in the trash on Thursday. Now my bbshd I've beaten it to death and it still operates like I pulled it out of the box this morning. I don't ride my bbs02 like the HD because it's a cruiser not a mountain bike and I've been easy on the throttle knowing they get red hot and fry controllers and yet still happened (last night actually) LMAO
What battery voltage have you used to your 02?
You can fit the HD controller to the 02 they run fine I did it and I've now dumped the stock controller for the BAC855 the difference is like night and day and I run 16s (67v) smooth and almost silent..
@@yj8471 where can I get a BAC855?
Would be nice if we could get some carbon fiber crank arms!!!
why tf
Given the weight of the battery & motor is it worth the cost for such a marginal weight save?
I thought I was set on getting the bbs02, but now I'm pretty sure I want torque sensing. Do you have any experience with the tongsheng motors?
They are great and tunable too with firmware but the lack of waterproofing is a problem. I figured a way around it, basically packing the gaps with heavy grease.
Here's the video for you: ruclips.net/video/T7ve958hJXE/видео.html
The pedal-assist feel on my TSDZ2 is nice, but the motor itself is a little weedy. On one side, that means it's not going to get impounded, on the other side, it overheats pretty easily.
@@DFX2KX what does "a little weedy" mean?
DONT BE SO CHEAP> Im homeless and still prefer the bbshd.
Not as good as HD and would have gone the bbshd with more reshearch period . If the controller blows for instance you can allways go external controller route by buying a grin phaserunner plug and play and if your batterys a good one you can set it with phone app up to 50 amps and increase perfomance . The bbso2 is a great little motor ! If you do the digital temp probe into controller and hit the throttle not on full throttle to long . If mine gets to 45c or more l lower the ppwer an lay of the throttle .
Best an only mod u can do with the 750w 48v . And can last if tode apopietley .
Ran my 02 for months at 25a...no issues
@@ricksanchez3628 yeah but I wanted home quick and had a 13 miles mainly on the road and flat ish, the next Monday morning I was just off to work and turn on an heard a small noise.

I have a bbshd that just come from luna usa to uk and on picking up the HD god what a chunky motor.
Maybe leave the controller at its factory settings...25a
If you lock the firmware you will definitely lose potential clients.

All of this is massively overpriced.
