does bafang make a 750 watt hub motor designed to be laced with a 27.5 wheel for a 2.8 tire
The motors are fitted to the width of the dropouts front typically 110mm and rear 135mm. No relationship with the wheel or tire size. Fat bikes will have wider dropouts.

yeah you can pretty much lace it with whatever wheel you want.

But I noticed that Bafang makes quite a few variations of motor winding (coil winding) though.
The seller almost never reveal which kind of motor you will get.

They do however, say "20 inch, 26 inch, etc" so maybe that's what it is?
But they don't ever say "12T, 10T, 8T, etc."

Timpo-
I know you posted a link showing a 135mm Bafang 750, but I spent an hour looking and never found anyone that would lace one to a wheel!

Yes, Bafang makes one. They're rating it as a 750/1000w. Actually sourcing it is kind of a challenge. And trying to make any sense out of the motor rpms rating is nearly impossible.

All of which is pretty weird as Juiced has been selling a 135mm 750 for years...

Laced to a 27.5" rim for use with a 2.8" tire makes a great deal of sense here. A find like that could encourage me to do another build ....

Among others. But nobody want to lace one up for you....

are there any e bikes with that motor you showed in the link?
Not as far as I know.

What kind of bike are you looking for? A hub driven ebike with a high torque motor?

Have you ever considered HillEater Galiano or WattWagons UCP GMAC?

They both offer GMAC + Phaserunner combo, and HillEater offers 72V, although I'm sure WattWagons will offer you 72V GMAC.

HillEater Galiano
$4,499 Canadian

WattWagons UCP
Equipped with Bafang Ultra as default, however I know Pushkar (owner) offers GMAC option, and there are at least three UCP GMAC in existence.

I think this is a new motor. That's why there is so little info available for it. Nobody is using it yet, possibly because of it power rating. When you get legal, anything over 750w makes it off road only in the US.

The only other non fat 750 I can think of is the Juiced bike - which is a complete mystery to me.

I refuse to consider ANY GMAC option until they replace that huge display that should have been replaced years ago. -Al

has anyone here used the GMAC option and its characteristics? I have been using Grins ezee hub motors for years with good results but want more power

I've been running a MAC 12t for 3 years now. That's a GREAT motor - IF - you can find one. I ran across this the other day, but no experience with them-


You WANT the 12t for the bigger wheels and tires, assuming your focus will be speeds under 20mph or so. Use the grin charts to see why. Grin SAYS the 10t will do anything the 12t will, but their charts don't support that...

Take whatever you can get, but you would also want the cartridge over a freewheel if given the choice. -Al

That is the MAC motor factory. Typically they would sell a single motor as a “sample” then require a multiple motor order. I don’t remember the MOQ nor did I look for the number in your post. I’ve always found them easy to work with.

I have a Bafang G360 motor in a 700c wheel with a 25a KT controller. It's pretty beastly - pulls a trailer full of kids up an 8% grade no problem. Bafang rates it at 500w but I think that's very conservative.

that huge display
Yes, the one with all the useful data?🤭 Teasing my friend you've mentioned your disappointment before.
I'm not bothered at all.

In fact, I really dislike every Bafang BBSxx series display except the old C965. I still use a C961when I can.
None of which are pretty.

Yeah I don't like that big display.

I think many people prefer minimalist look of something like EggRider.

Andy Kirby on YouTube called CycleAnalyst a "goofy looking thing", I really think Grin needs to update their display... well overdue.

Argh. This fascination with a look rather than superior functionality is laughable. Which display offers anywhere near the useful data? While the EggRider is an attractive alternative it’s too small and for many more difficult to manage. I have lots of happy EggRider buyers but more than a few put off by the size a teething pain setting up. I use my CA3 and shunt to get real time power reading and data on my BBSxx builds. But as we see here YMMV.

I knew you were reaching for my chain..... I figure if I mention it enough, MAYBE the right somebody will get the message!

Regarding "superior functionality", like you, willing to learn/adapt. Please tell me what else would need to be displayed, AFTER initialy setting up. Much more available, but this is what you'll be looking at most of the time. In other words, info at a glance.

Bafang (color):

Color KT:

KT LCD (mono) exact battery voltage available with 2 clicks

All 3 of these are compact displays, measuring about 2.5 x 4" (+/-)

Egg Rider - and let's keep it simple. I don't even own a smart phone
Nice, though a little compact, display -about 2x3". There could be some setup issues.

Grin CA-3
Granted, to fully utilize it's capabilities, a degree in electrical engineering would be nice. WAY over the top for most of us. If you look at the pictures it should be pretty easy to see. 2 lines of data, really? I couldn't find the actual dimensions, so big will have to suffice...

I do admit that my preferences may not be shared by all, but it should not take much to see the CA-3 DISPLAY is clearly/badly outdated as compared to others that are available. It needs updating badly to match the quality of the display up with it's capabilities. -Al

There's absolutely no reason CA-3 needs to be that big. None. That looks like a gadget from 1970s or 1980s.
Whatever CA-3 functionality it has, it's just simply a matter of software updates, which I guess won't take much of data storage space.

Look at the spec of Qualicomm Snapdragon. one of the most popular mobile processors.

Anyways, my point is, if Grin wanted to develop a minimalist CycleAnalyst, I imagine they could easily do so. And in my opinion, it's well overdue. :confused:
If that display contains 10TB of data with 16 core processor or something, yeah okay I'd kind of get it why it's big... but no, it needs to be simplified.

One of the best things about GMAC and Phaserunner is how compact they are for given specs. Not so with CycleAnalyst.

I’m one of the dullest bulbs here. Me thinks you do protest to much. You post and help fellas here we’ll beyond the difficulties of a CA3. But we’ll agree to disagree. The CA3 is a support staff dream. For me.

thanks for the discussion. I value your input even when we have different views and experience.
