Anyone in UK/EU riding with Bafang G062 or similar?

[Slippy One]

I'm thinking of purchasing a Bafang G062 for the 80nm torque but the seller says the "750w" sign is etched onto the motor, which would get my ride immediately confiscated if checked. Does anyone know if this is true? Could I etch over an etch using laser engraving or similar to say 250w instead. I know Grin offer "250w" laser etching for their G062 but with fees and import duty, would cost nearly double the price of one of these motors from AliExpress (currently £215 for 750w).

I intend to use the bike legally, i,e 15.5mph, no throttle etc but need a torquey motor for my new commute, as there are plenty of hills and my 50nm motor really struggles, where 80nm would be perfect.

The law states is that the motor cannot exceed 250w continuous, which is misleading at best, ignorant of how they actually work.

I think you may be somewhat buggered because the G062 is either a 1000w or 750w unit, even if you changed the etched details on the motor it would stand out as a high powered motor, but on Amazon they are showing a G062 complete in a fat bike wheel with a foil sticker for legal power, but I am dubious how legal it is, I have gone to mid-drives, a little bit more discrete. https://www.amazon.co.uk/BAFANG-Ele...pcontext&ref_=fplfs&psc=1&smid=A2LK2QVJRCRIP4

 

[Slippy One]

OK I stand corrected, 85nm of torque! Anyway, none of these ads show where the 750w label is located, I was hoping someone says on the drive side, where I could cover it with a large cassette, surely someone in the EU/UK has one of these motors?

Sadly a mid drive is out of the question.

As for standing out as a high powered motor, it's a similar size to the non branded one I'm using, which has a 250w sticker on it, would a roadside test realistically move beyond a 250w sticker displayed/? Especially if there's no throttle and cuts out at 15.5?

If anyone has recently bought one of these motors, could you please send some pics for me? lol

Perhaps this what you are looking for 36V 48V 250W Bafang Motor Brushless Geared Fat Wheel Ebike Rear 175mm 190mm | eBay UK not sure, but the 9 pin connector looks like the low power one not the normal one for the 750w / 1000w versions.

Just looked, and this 250w case is the exact same dimensions as the G062, so this could work. The G062 magnets are way bigger but that's the only diff I can see from the diagrams..

 

[dgc]

The GO62s have three alternative connectors depending on the wattage as I have seen before where the connectors have burnt out usually because the owner has put to much current thro', I do have a bike with the Bafang 500w 48v geared rear hub motor on it and a rear wheel with the 500w direct drive rear hub, but as before the TSDZ2(B)s with torque sensing suit my needs and can get more range on the battery in comparison.

 

[Slippy One]

I did see that 9-pin Bafang advertised, and the specs say 65nm torque which I'm not sure it's worth upgrading from my current 55nm. I'm almost certain that 85nm is what I need, just trying to avoid roadside confiscation. I guess I should just stick with the 250w and pedal harder but where's the fun in that?

 

[dgc]

Yep, off the Bafang website look for the H550 series (RM G062) you can see the power goes up along with the weight.

Woosh ebike in UK sell a legal vesion of this motor.

 

[dgc]

Comes back to spec again, what is the torque the motor puts out if it is 250w unit.

 

[Slippy One]

I just saw that Woosh motor has 500DC in the etched serial, seems suspiciously like them selling a 500w as a 250. Need a 190mm dropout too. There must be an easy way to either cover these serial numbers or grind them off. If it means I don't lose the bike in a roadside check, I'll try anything.

Sandblast the case, repaint, polish etc, all seems a bit crazy, but so are the UK ebike laws, and I'm risking points on my license, fines for not riding an unregistered moped, and not having insurance if caught.

Must be someone riding around in the UK on one of these motors, what do they do, take the risk?

 

[dgc]

You need to clarify the spec for this motor with the seller as they say this, but I am still dubious, even with the 1:5 reduction ratio on the motor which is fairly standard, I still look at Voltage and Watts, I have a 500w motor which the makers say is legal because the controller has a link wire on it to reduce the power to 250w, anyway :-

This rear-drive motor, which is compatible with the disc brake, has a rated power of 250W, a reduction ratio of 1: 5 and a maximum torque of 80 N.m, providing ideal power for vehicles. Strong and efficient, this motor working together with a thread-on or a cassette freewheel speed change mechanism, greatly enhances riding comfort and is suitable for beach buggies and snow bikes.

Specification:
1.36V/48V 250 Watt
2.Cassette / Thread-on rear Hub Motor
3.Dropout Width:175 MM / 190 MM
4.Color is black
5.The motor can be installed on standard fat/snow bike easily
6.High starting torque,Max torque is above 80N.m,good performance on climbing
7.Clutch is used on drive unit,more safety
8.High efficiency,low consumption,low noise,long travel distance

Just making sure that it is clear to you that the motor doesn't make more torque all by itself. More torque requires more current, proportionally. You need a controller and battery that can provide that additional current, and it's not going to happen on a bike that was designed to support 250W, since prebuilt bikes are built to the bare minimum to support the stated specs they advertise.
So, to go from 50nm to 85nm will take 85/50 = 70% more current (and power) at the voltage you are currently running.
If a motor has greater gear reduction, then you might be able to climb the hills easier, but slower though.

 

[dgc]

So that's why I change to a mid-drive where I have a 9 speed rear cassette with a 11t - 46t range, Slippy One out of interest what is the width of your bottom bracket 100mm or 120mm? Problem is you can get say a Toseven DM02 250W mid-drive for a 100mm - 110mm wide bottom bracket but you are up in the £300+ area, all you would need is the battery.

 

[Slippy One]

I'd really love a mid drive, maybe my next bike. Bottom bracket is 100mm but it's a folding bike with all sort of bits welded to the BB so it really needs to be a hub motor.

I'm probably just going to buy one and lace it in. How hard can it be to spray over the markings and put new ones on? Unless the police are smart and notice the L1019 plug.. lol

Are there any UK G062 riders out there? If yes, what do you do to stay safe?

Yeah thanks for heads up, my bike had a 18a controller OEM but I've had a 25a in there for over a year now, the motor has always been underpowered, great on flats but groans on most inclines. I've seen my display show 1400w peak but not sure if that's accurate for a 25a current, but that should work. If I'm wrong and 85nm is still rubbish, I've lost £200ish, but I'm hopeful those bigger magnets will be the key to more oompf.

I have been in the same position with a folding bike, yep it has the frame support under the BB to allow you to stand the bike when folded, I built a set of matching 20" wheels for it using a Bafang 36v 250w rear hub from a Pendleton Somerby e-bike, but I use this on the flat down towpaths so was able to keep the overal weight reasonable and power down.

Well from my research, that bafang hib 36v 250w you laced up, is the exact same motor they also state 48v 500w magnet size with the 9-pin julet. The actual motor case size is the same with all of these, including the G062, with the only outer difference being the 3 different higher current cables they use, but no copper would notice that.

The inner difference would be bigger magnets but you can't see that! lol

Here's a pic of the G062 on the left vs their 36-48v 250/500w G060 innards if anyone is wondering. I also assume the 1000w to be the exact same as the 750w which would make sense from a manufacturing perspective.

 

[dgc]

Same with cars nowadays all built on the same platform but a different dressing on top.

 

[dgc]

Look on Amazon UK you find the Bafang electric bike 36v 250w 190mm for a fat bike with the G60 model code.

Yeah seen that, but it seems expensive to buy a lower torque motor, replace the innards with the G062 just to fool the cops.

Here's the requirements from google:
UK law requires e-bikes to have a sticker or plate that is visibly and durably marked with the manufacturer's name, the maximum continuous rated power of the motor (in watts), and the maximum assisted speed (in mph or kph). If the bike doesn't have a plate, these details must still be marked on the vehicle itself.

So in other words, I'm fine with the G062 as long as it's cleaned of all markings and Bafang CE 250w sticker displayed on the bike frame which is much better and legal. I think they care more about throttle and top speed over motor watts. Haven't been through any checkpoints yet but you never know, and I have ridden past a truck full of confiscated bikes ready for crushing..

Laws are confusing on motors though..

 

[dgc]

It's the same old story, we all start enjoying something then the erks come along and spoil it by riding around like lunatics, in to thievery etc etc which puts all e-bike riders under the spotlight. Really it comes down to unless you buy an e-bike from a reputable outlet ones e-bike is most likely illegal and that is the current state of affairs even though a these can be illegal as well. I have ridden past a row of police cars and officers and just smiled, always wear a crash helmet, glasses etc etc no problems, so far. In the local supermarket I ride past motorways officers taking their breaks. I made sure my e-bike(s) looks like a professional build.

I'm going through central London, I hear they do random checks outside Liverpool St station, confiscate anything with throttle and/or beyond 15.5mph with fines and license points. The vendor just sent me this photo of the label on the 1000w version, which is the same as the 750wDC, looks easy to dremel the serial off and spray with matt black.

All this fuss because of dumb laws, who in their right mind thought 250w was enough...

Same size case as the 250w version just heavier..

I generally don’t trust AI, but I’m too lazy to read the actual law. Sort of implies more than if you just get caught with an illegal bike though. (AI bolded the text, but I guess in theory, if they want to set an example…)

“Yes, in the UK, there are potentially additional and severe charges for removing or altering identifying information on an e-bike motor, especially if done to evade laws. The act of riding an illegally modified e-bike on public roads is already an offence, but tampering with identification numbers can lead to separate, serious criminal charges related to forgery and fraud or tampering with vehicle identification.“

Oh Christ I’m screwed.. maybe buying the g060 for its 250w serial and swapping the innards with the g062 is the right thing to do. This puts it in the same price bracket as importing the Grin G062, which they offer 250w laser engraving for EU customers..

From their website:

Laser Mark 250W on Motor​

Laser Engrave 250 Watt Continuous Power Rating on Motor Side Plate. This is Truthful. ALL Hub Motors Offered by Grin Have an Operating Point (RPM and Allowable Temperature) Where They Can Only Sustain 250W.

That is truthful!

And to add from their page: (it’s EU but identical to UK)

“Contrary to common assumption, European ebike legislation does NOT limit the maximum output power of the electric motor to 250 watts. Rather they define a maximum continuous rated power output for the motor when it has reached thermal equilibrium, at the manufacturer defined maximum operating temperature.

That's why industry leading Bosch and other "EU compliant" systems will pull upwards of 800 watts of battery power. Ebikes would be far less popular in europe if they were truly limited to just 250 watts.

Unfortunately there is no such thing as a meaningful or unified power rating for electric motors, as we have explained here, hence we don't generally classify motors as having a specific power, and none of our motors have a formal power rating engraved on them because there is no such thing. But this has caused difficulties for customers who need some official power spec to demonstrate compliance , so we offer a laser engraving service to those who need this.

Technically even our largest hub motor will struggle to put out 250 watts of mechanical power continuously if heavily loaded and running at a very low RPM with poor air flow, and in a worst case ride situation with thermal rollback enabled they will indeed become limited to 250 watts or less. As a result we have no problem to engrave a 250 watt rating on the motors to facilitate compliance with this poorly spec'd legislation, and will gladly back that up with hard data when called for.”
