Bafang G062 / G063 Info

[Ebikebuilderyt]

So what size is your axle that you found it risky on? 12mm? How would you feel if it were a 14mm axle? No concerns? Or is it also the gears that are a worry for regen?

Perhaps DD is the way to go for full regen? Maybe this is why Grin removed the option to weld the stator on their Bafang motors this past year?

I also wonder how Engwie the Engine Pro 2.0 is faring with their regen implementation with their customers? I don't think they have a torque arm on it right? That's the bike that originally started me down this track once I'd heard it existed. But now I'm glad I didn't order it as it has some limitations with their controller implementation I've read. So Grin is the only game in town currently for being able to implement all the features and options of regen.

I

I broke the 12MM axle with regen and only one v7 regen torque arm. If you look up the torque required to break M12 axle, compared to M14 axle, the M14 is almost twice as strong.

I believe the axle broke because I only used a single v7 regen torque arm... and I was using quite high levels of regen to test It Lol.

I will try it again in the future, with two v7 regen torque arms and my G63. I feel fairly confident it would be OK with a V7 on each side.

Yes, the G63 .1000 motor that I ordered on ali express came with M14 by default. Bafang also makes the G900 hub motors with M14 axles, So it seems bafang is using M14 axles by default for the 750W+ motors now. But always check with the Ali express seller of course. If you see a bafang motor with the red L1121 motor cable connector, it probably has an M14 axle.

Im not sure how the engwe with regen works, But i imagine they have clamping dropouts on the bike? Or some kind of torque arms / torque plate that is very secure. It definitely needs something to hold the motor, beyond the standard hardware bafang provides.

I think Grin Tech , yeah, they realized the motor can just snap it's own axle, basically.

IT was necessary to use a special Loctite (548?? i forget) on the planet carrier to bind it to the axle , to avoid the "play" from the parallel key, when changing between acceleration and regen.

It was a lot of work - tinkering around, welding clutch etc. I will admit, it would be easier to just get the Grin tech all axle DD hub motor. But if you are a G62 enthusiast It is a fun project.

G62 Regen is no joke though You need V7 torque arms on each side!! and it cant be stressed enough.

I think the Nylon gears, when doing regen- there is probably something about going back and forth (accel and regen) with the nylon gears, as opposed to just 1 direction, that I imagine wears them out faster. I absolutely shredded some nylon gears hahah I would buy a bunch of spare nylon gears if doing regen.

(I dont know about using fully metal gears, with the welded clutch and regen, because I think if the gears broke it could lock up the wheel.)

Thanks.

Yeah, I may get a G063 and try it with those hybrid nylon/metal sided gears and see if that's the sweet spot.

With two V7 torque arms on a Flipsky 75100 Pro V2 just to see what the fun is all about that you're sharing. Seems like a blast.

I was wondering though if it's possible to shut off the bluetooth on those while riding? I like keeping all that stuff off if I can. Maybe figure out a dedicated display for it somehow. I saw a post about one guy (stancecoke) who was creating something here. https://endless-sphere.com/sphere/t...-display-and-t15-t17-bb-torque-sensor.125611/

Also it seems the G063 with cassette is a lot cheaper now ($233 shipped) than the G062 ($299). Unless I'm just not finding the right reseller page link for one. So it might just be easier to get the G063 nowadays.

Did you have to pay any shipping from them or that was the total price shipped for you at $233? If so, that's a deal.

It seems the G63 is bafang's replacement for the G62. At some point in 2023 / 2024, the Ali Express listings switched over and the G62 was phasing out. In the g63 there were a number of incremental improvements - better jam nuts that are easier to remove, strong waterproofing glue (not easy to open!), the windings look cleaner and more consistent. I opened up a g63 at some point on my channel, and its on a bike I will ride this winter

I got the g63.1000 (5.5) with the red L1121 connector , its probably the easiest way to find it at a low price and have a good chance of it being an M14 axle. It may be difficult to find G62 with an M14 axle- I have heard RisunMotor had M14 axle g62's in the past.

If doing a dual motor setup, the g63.1000 with the 5.5 wind can be easily paired with the G61.1000 front fat motor thats also available in 5.5 wind. I had some stuttering problems with dual motors in VESC when the front and rear motor was a different winding.

but Yes, It would appear G62 is an endangered species! Potentially, not being manufactured by Bafang anymore.

Thanks for that. Yeah. Seems so.

I did have one reseller say they can custom order the 14mm G62 for me still.

And that link you provided for the G63 from PSR Ebike Store has been great on the communications. Better than all the others so far.

They even just said this:
"The motor is equipped with a temperature sensor, and the temperature sensor and the speed measurement line share a white line

bafang has now been upgraded to 1121 waterproof cables, which can provide a greater current"

That really true? Did you find that to be true for yours? It didn't seem so from the video that it was the case.

CONHISMOTOR Official Store are the ones that claim they can offer the G62 in a 14mm axle for me if I request it.

Risunmotor have been jerks to talk to. They say they have no 14mm axle versions for sale.

Seems that I'll probably go with a G063 from PSR Ebike Store and try to adapt it to my Baserunner L10 or Z9 to mux the speed and temp on the same pin. Just need to figure out which pin that is and find the pinout diagram for both. Edit: Seems it's the white pin listed in the diagram below.

Man, I really want to believe it already has a temp sensor built in. That would make the G63 the way to go nowadays.

$233 delivered is low enough to be worth playing around with.

Edit: They just shared this pinout diagram:

Great customer service from this guy for me today.

They say they provide the other end of the cable so I can adapt it as I need. However I really wished there was an L1019 to L1121 adapter cable. I'll have to research that and see.

 

[OkinawaJapan]

So if the motor side has an L1121 male end on it, then I'll need a female L1121 connector to ? for the Baserunner L10 adapter cable?

All controllers have female on the controller side, right? Because all hubs have male connectors on the hub side, right?

Baserunner/Phaserunner L10 (left pic below) seems to have a female L1019?

So I guess that means I need a Female L1121 to Male L1019 adapter cable?

Adapter - Motor Cable - L1019 Male to L1121 Female

Adapter - Motor Cable - L1019 Male to L1121 FemaleNice and short! Allows you to adapt a Grin Phaserunner or similar controller (L1019) to another motor type.NOTE: Bafang G063 do not seem to be compatible, they use their own unique wiring (unfortunate!)

This it? This look right? I think that's it.

It's good to see that they're available. That means it's likely to work then I believe.

I

Axle is 12mm. I have V7 regen 12mm torque arms on both sides. Gears are sandwiched steel nylon. Welded clutch will hold regen but axle key is now the weakest link. I have super tight clutch body/axle fit that helps but still.
With all the mods the performance is awesome for the stealthiness
If I had time and some $ to play I would next go and mod all axle fat hub for 15-20kw.

Hey Boosted. Great write up here. Thank you for that.

I wrote to Risunmotors via the Aliexpress chat and they say they can't sell me a 14mm axle in the G62 version. I've asked two other resellers and am awaiting an answer. It seems like the G063 is taking over nowadays. Do you know where to purchase a G062 with a 14mm axle? I'm also wanting one with an L1019 connector for use with a Baserunner L10 controller.

I was watching @Ebikebuilderyt 's videos on youtube (and loving them). lol. Where he is adding a thermistor to his. Seems like a PITA but I'll do it if necessary, but I'd rather find them sold with the temp sensor already installed and the grey wire actually present and connected in the L1019 connector. It seems Bafang isn't actually installing the grey temp wire even though they have an L1019 10 pin connector on it. Cheesy economics right there from them.

Anyone know a source for motors? Grin only has the 190mm axle version and it's a 6.5T which he says is super loud, which I'd prefer to avoid. I also heard their custom order of the 6.5T didn't actually come with the grey wire installed in the L1019 connector they found when they received their shipment. But does have the sensor installed. So it's not usable as is anyway.

So I'm looking for a 1000w 6T 170mm width, cassette model with 14mm axle with temp sensor, actual grey temp wire present and an L1019 connector already all connected up and working from the reseller. If that's no longer available these days, and no one knows a source, then it seems that the G63 may be the new and only game in town. But it comes with an L1121 connector instead of the L1019. Which I will then have to figure out where to buy or make an adapter...

Such a PITA right now getting what I want in a Bafang motor. Any known sources for ordering and actually getting what I want?

Anyway, love the original post details and all the further info shared in this thread. It's the best one on the net on these hub motors right now. Thank you.

I plan to do regen with it with dual V7 Grin torque arms, so I think the 14mm axle is required, right?

I did get several M14 axle G062.750's (6.5T) from Risun Motor. Not sure what their current stock is. If this is important to you I would ask the seller if axle measurements are 10x12 or 10x14 for clarification.

I havent looked in like a year, but last time I looked you cannot find L1121 cables thicker than 2.5-3 mm2. Grin (and aliexpress now) sell L1019 cables up to 4mm2. So I prefer the L1019 over the L1121 for that reason, and also because its more compatible with controllers. All of the OEM motors (L1019 or L1121) seem to be 2.5-3mm2 phase wires, except for perhaps GRIN's which MAY (im not 100% sure) but may come with a 4MM2 cable.

The GRIN motor does come with a thermistor I believe. However I have never seen any other ones come with a thermistor. Its not too hard to add one if you have a compatible controller

The MXUS GDR19-FAT motor has its own issues too, but its a powerhouse, has an M14 axle, can fit a 4MM2 L1019 no problem, is mechanically stronger and also comes with steel gears OEM.

Good luck!
