Bafang CAN BUS BBS02 First Look Hands On!! Bafang CAN't do this to us!

[@rdkuless]

to extend the life of the motor.. I pack the reduction gear with "Black Moly grease LI2"(Lithium 2) specifically for this application.. Don't use anything but the black moly li2 in your reduction gear.. (thick like creamy peanut butter). If you have a noisy motor, that means something is rubbing and will eventually damage the motor. Packing the reduction gear increases range and stability of the motor and makes it quiet again..

[@keithfritze6538]

I use Mobilgrease 28. It's expensive, but you can notice the difference when you pedal.

[@ryanclapp6467]

In convos, the sentiment is the spades are just a temporary roll-out as tooling and final touches are put into the products for full ramp-up. JST's are likely to be installed on first official prod launches.

[@ryanclapp6467]

Not proprietary - just another type of connector from Julet. They're not as common, but adapters (and pinout diags) exist. Should be able to reuse our existing periphs with those.

[@ryanclapp6467]

UART is indeed awesome, but CAN offers a lot more for granularity, and as you noted, control! I see this being an easy 'win' for manufacturers utilizing Bafangs' tech.

[@justinb7940]

yeah a lot of other upgrades use CAN bus. in the future there could be integration with internal geared hubs with auto shifting. they would likely use CAN

[@dado304]

UART is not awsome. And what you mean by control with CAN controllers? CAN controllers have lot less parameters to set. Here we will be lucky if you will be able to set max power at each pas. M500, M600, older M620 did not have this option and was everything hardcoded.

[@rshawiii]

Thanks for the update. Here is my question. I've got 2 BBS02 builds that I'm happy with. I've got a 3rd motor on the shelf. At some point in the next year, I want to do two more builds (to home in another state where my son lives). Would I be better off to get a Uart style kit so the builds are the same and can share/swap components or not worry about it, and just know that one build is all CAN style components and controller. How long will you think you'll be able to sell older style kits?

[@HB-yq8gy]

Well I'll glad I purchased in 2022 from JNO the UR version BBSO2.

[@MountainParameters]

This makes me wonder, if you consider that CYC seems to have enabled the ability to tweak your controller settings via Bluetooth, does Canbus have an advantage over Bluetooth?

[@zentechnician]

Waveshare has a uart to can adapter for $8.99. bi-directional communication. I am not a fan of those stupid connectors anyway. Like we need more weird shaped connectors to stock. Just cut the ends and use whatever you want you can easily make your own "waterproof" sleeves to go over whatever connector you want to use. Use the marine shrink tubing that has glue in it and the large normal shrink tubing to make sleeves that fit inside each other. Use the marine stuff on the outside so you get a waterproof bond at the wire and the normal shrink tube. You only shrink the marine stuff, leave the normal stuff unshrunk so you can roll it back to get to your connector. It's a bicycle, not a submarine. It just needs to keep the rain and snow out.

[@rdbagaming]

my question is lets say they change the connector for the sensor can we cut the connector and change it with something standard if the specifications is the same ???

[@themanheman]

Well dam, I was going to build my bike w/bafang motor, but now not to sure about that. Might just go back to my first thought of an e scooter (big one).

[@rdkuless]

John.. if someone wants all the UART peripherals, can they bring a CAN fitted motor to you to replace wll the CAN with UART..?

[@JohnnyNerdOut]

It would just be replacing the controller mostly. Yes you can.

[@jamesburgess9101]

Because it's a bus you can hook more than two things together which is all that a UART will allow, is that the goal?

[@Zwebx-oz3nf]

Looking forward to the hd reveal will sub fo sure

[@Knapweed]

Are any of these changes a benefit to the customer or is it all self-interest on Bafang's part?

[@SimonBauer7]

can allows for much more control, much better variation in the commands you can send. can bus is better, and used on every single car now.

[@ryanclapp6467]

A little column A, a little column B, actually. Wins and loses on both ends of it.

[@NoInfoFound]

@@SimonBauer7 Maybe Ai can weigh-in on this: "Why Tesla is moving towards more Ethernet usage (vs. CAN): Advanced features: The growing complexity of modern cars, including autonomous driving features, require high data processing power which is better supported by Ethernet. Reduced wiring: Utilizing Ethernet allows for fewer cables in the vehicle, reducing weight and simplifying the wiring harness."

[@Knapweed]

At least there are some benefits, which is a good thing.

[@th3welfarewarrior]

@@SimonBauer7 Some vehicles are leaving canbus for ethernet.

[@noah786]

Adapter for proprietary cables?

[@ryanclapp6467]

They exist - Julet-made are the main ones, but like so many other connectors, various 3rd parties will and have made their own.

[@19Nick80webb]

Not to worry, Eggrider V2-3 and the Eggrider C1 are both can and Uart compatible with adaptor cables, the C1 is amazing with heaps of stuff coming down the firmware pipeline 👍🏽🥚📲🚲⚡️💨

[@rirrid5662]

Does that mean you can totally replace the ECU so to speak with the Can-Bus? (don't understand how it works..)

[@hosgoth]

did you try the old UART controller on it to see if it works?

[@JohnnyNerdOut]

Not yet

[@rdkuless]

I just got my new BBS02 750w kit.. the website looked like UART... and there are no directions in the box.. There are no youtube videos on how to install the new CAN motor kits.. My kit cables / light cables look different from yours.,, Hopefully i will be able to set the wheel size on the new CAN kit.. i have the old UART programming cable.. and if the new pc18 display won't let me set the wheel size to 26"... i'm going to be in trouble... There was nothing wrong with the old UART kit.. why the change..

[@JohnnyNerdOut]

Install should be the same essentially as the video I made for it. The old UART program cable will not work with the new motors, though you need to get a specific one made for it, which I do carry but it is quite a bit more expensive.

[@rdkuless]

@@JohnnyNerdOut you just hit the nail on the head, this required New Cable "is quite a bit more expensive". This is what Apple does with their computers. you buy a new one and none of the old cables, apps, peripherals are compatible.. you must buy all new (multiple) $40 cables to get the new computer up and running. Some of us are awake to the planned obsolescence . LOL

[@justinhaller2055]

I like the ability to repair my own stuff! Come on Bafang...

[@Hybrid600]

Swap the controller with a $100 VESC based one and have the thing that will make the most difference: field weakening!

[@SkateFit1]

Quick question. Battery wise, no need to go proprietary bafang batteries i hope?

[@ryanclapp6467]

From what we've poked and tested, no need for proprietary batts from them. They have no handshake or direct auth for the batteries. But, they can certainly change that easily with updates and changes. Hopefully they do not and keep it as is.

[@JohnnyNerdOut]

Nope! Any 48-52v will work (at least so far)

[@SkateFit1]

I use only the 500w, 36v BBS 02. Will it also be available?

[@ryanclapp6467]

@@SkateFit1 As of time of writing, any batteries that theoretically work with prev UART models should be compatible with CANN models. Theirs no "checks" or handshakes in the CAN models that would interact with batteries, other than basic reads on params.

[@johnsheetz6639]

It sucks but then aftermarket will catch up. It might not be good news for Mr nerdout though he probably has a lot of old model stock and he's going to have to buy a whole new batch of motors and supporting parts

[@oldmanwithebike]

The next move will be a bms firmware locked proprietary battery.

[@dallasangler]

Other than a few connectors is this just a defunct M620 series rebadge?

[@JohnnyNerdOut]

I don't think so. Its the same BBS02 with a new controller.

[@MHH3180]

One of the benefits of conversion is that it is not proprietary. Bosch has not been able to break in to the market with their kit (kind of nest looking) partly for this reason?it is popular among recumbent builders, but that could be just because they tend to be a bit elitist). The ToSeven DM01 is so very close to The BBSHD, but a lot simpler, lighter and technically legal. It can be programmed in so many parameters from the display. Why would someone spend more for the Bafang BBS02, plus the expensive programmer? I am not trying to be snarky. Sorry, I see it reads that way. I really want to know. Some might say it is for Bafang's legendary reliability and quiet, but heck , used within reasonable, the 144+ TSDZ2's I've installed ha e even been amazingly reliable.

[@michaelbrinks8089]

How many miles or years does a mid drive motor last?

[@JohnnyNerdOut]

Technically forever as long as you replace any small parts that fail along the way

[@michaelbrinks8089]

@JohnnyNerdOut I'd love a 750w mid drive electric velomobile. They're expensive but I'm really liking the idea of a mid drive velomobile that could handle crusing at 35 -40 mph....Especially a 4 wheel Quattrovelo velomobile. That could be custom built. With a fully enclosed lid & where the seat could unfold out flat into a bed. So your velomobile could convert into a weatherproof sleeping pod. Sorta like a micro motorhome. With an electric jacket in winter & some 12V fans for Sumner possibly also 12V cooling peltiers & a mini ice cooler to stay cool. The AC system could be a combination of small 12V DC fans & peltiers that blow air through the small ice cooler blowing out cool air. The body of course would be covered in thin lightweight laminated solar cells. Might have room for 75w worth.....Velomobile/ mini Aptera mini electric motorhome. Crusie across USA using fold up lightweight solar panels stored in mini trailer. That double as shade awnings for the velomobile & campsight.

[@rdkuless]

is this also 750w and same number of amps.. this is what computer companies do. they make the computers software update incompatible with your old Apps and peripherals. That way you not only have to buy a new computer you have to buy all new cords and gadgets.. it is planned obsolescence. I just ordered a UART BBS02 that is compatible with all my backup parts.. And i don't want to fill the landfill with new (unusable) electronics. Green Baby..!

[@unwillingful]

You're making me want to doomsday prep and buy a bunch of BBSHD motors with uart 😅

[@ryanclapp6467]

Just order replacement UART control boards instead. They only require minimal rewiring to fit the CAN models. Similarly, in due time, parts for the CAN models will be available and we CAN (pun intended) order CAN control boards and drop them into older UART models.

[@unwillingful]

@ryanclapp6467 I feel like other things are on the horizon... This canbus model is just the beginning... I'm honestly considering purchasing another BBSHD and X1 Pro Gen4 just in case I can't get them in the future... There's a trend with laws that I feel may outlaw these motors but I live in Washington State where certain individuals just outlaw stuff with no reason...

[@dado304]

Yellow triangle is a CAN bus from battery, dont tell untrue if you dont know whats that! Also why you want UART? Old controllers and 50 year uart bus?

[@JohnnyNerdOut]

You don’t have to use the can interface with a battery. You can though and get more information on the battery but it’s not required. 98% of customers will not use that can interface I would estimate

[@jankazimierzcybul-jl8zi]

I don’t like the new one neither. I’ve bought a 3rd old version bbs02b hearing they’re making changes so I’ll be good for a while with spares just in case anything goes wrong, in over 2 years of daily use I’ve had to replace just the clutch pawls

[@jdfriar]

im glad i bought my motors before this change.

[@johnhoey6512]

Couldn't you just maybe use adapters for the new plug design? Or hard wire? Well I guess the displays won't work then right ? Wth why change the plugs...so we have to spend more money.....

[@owenminor]

Why buy a heavy, DIY motor with a walled garden controller? Might as well go for the CYC for a quality experience, or a ToSeven/Tongsheng for the low end cheap experience? Bafang is killing their market proposition.

[@JoLe1991]

the M435 and M635 bought some real improvements, Magnesium casing, torque sensor, heavy duty construction. It came with the CAN protocol and you definitely needed BESST, because for some reason, stock configuration is always total garbage with bafang motors. overrun, poorly calibrated torque sensor etc. converting the BBS02 to CAN is totally pointless, they'd better figured out how to make the M435 more affordable and ship it with proper parameter settings. if aluminium instead of magnesium would have significantly cut the price they would be stupid to insist on shedding a few grams with a different metal. nobody cares if the motor weighs 200g more or less

[@jasondundom1390]

It always pisses me off then companies go out of their way to screw their customers out of more cash by changing shit.. i bet they loose business over their programing cable scam

[@RodMesa-e2t]

Aw man… I really dislike this new direction Bafang is taking.

[@JohnnyNerdOut]

Ya, we will have to see how it pans out.

[@briankent6164]

I won't be supporting bagang by giving them any of my hard earned money. Too many other brands out there to switch to
