First look at the new Woosh FB Six

[KirstinS]

Personally not a fat bike fan

But the spec and price and look of this looks great. Certainly makes me want to have a go one at the very least

Good luck with it Woosh

 

[Woosh]

Thank you Kirstin.
The Rio FB is selling surprisingly well.
That's why I am progressing this project.

Dosen't make sense if it is laser marked 350w, it won't comply with EN15194. No matter how many amps or any speed restriction applied it will be a S fat pedelec capable of a lot more using the same programming lead as the BBS.

I know that.

So what is the technical reason you didn't choose the 48V 250 W version?

 

[Woosh]

there are only two models to choose from: the MMG330.250 or MMG330.350

The 350 is the better of the two.
There is no other reason.

 

[Wisper Bikes]

I know that.

So it's illegal to ride anywhere in the UK where the public have access? If so that's a real shame. I was getting excited!

All the best, David

 

[Woosh]

it's nothing to do with EN15194 which requires correct labelling, including nominal power of 250W.
the motor model number is just a model number, not nominal power.
You can for example run the G330.350 at 36V 10A if you like, it will oblige.
You can also program it to run at 48V 10A.
There are quite a few factories which have obtained EN15194 for their fat bikes fitted with with the G330.

 

[Woosh]

This is a typical OEM labelling, which does not replace the EN15194 label but is reassuring:

This motor has in fact a larger core than the one in the G330.350.
The motor power is controlled by the controller.
It is this critical component together with the speed limiter that ensure compliance.

 

[Nealh]

The issue about power will keep on going in circles, the only relevant matter to keep plod or any one else satisfied is that the motor unit has a OEM 250w engraving on it.

G330.250 rated power 250w.
G330.350 rated power 350w.
Each will have the W rating engraved just as the BBS have or any other motor should have.

 

[Woosh]

Hi Nealh, I only have to ask for the OEM marking.
As I said before, that marking does not replace the EN15194 label.
The alternative is to fit the G330.250 and still run it with 48V.

 

[anotherkiwi]

I really can't see much difference between the two other than W rating on the bafang page, that is why I asked. My vote is for the MM G360.250 which has PAS and no torque sensor I think that this might be the new form factor of the BBS02? It also handles 12, 13 and 14S batteries (43/48/60V).

Does the 330.xx series have the 104 BCD spider for mounting the chainring? There are no photos of the other side of the motor.

 

[Nealh]

I have only seen/found the G330 references, haven't yet seen the G360 on their web site.

Ah found it now , along with the others inc G510.1kw . Don't look at that one Woosh .

Is the CB version a TS model ?

The G330 250w probably for most is the model to look at encompassing 10/12 & 13s formats, also the shell sizes are all a bit different except the two G330's. If the G330.350 is engraved 250w then gets my vote.

The G330.250W is the one for legal public use which is correctly marked so don't rule that out David.

... Have there been court cases where the legal definition of the power on a pedelec have Been teased out or is this all speculation?.
My reading is that the manufacturer eu distributer makes a claim that their product is compliant with en15194 and then puts labels as specified in the act including the logo CE mark and power rating on their product. The manufacturer is potentially guilty of fraud if the item is not compliant. The manufacturer can cover themselves to some extent by getting third party assurance by submitting the product to national standards testing services, in any of the member states.
Whether there are additional labels, engraving or other markings on the motor is irrelevant.
As has been discussed on a number of occasions, the actual mechanical power through a motor is dependent on a number of factors, including the nature of the controller( if any ) used and the supply voltage and maximum current allowed. So is not the manufacturer is asserting that their system ... Motor , controller and battery when used in the manner supplied is compliant with the regulation?

 

[Nealh]

The letter of the law says 250w max continuous rating without overheating, No where though have I seen anywhere that states the max amps or even voltage, but 48v is always spoken of as the max allowed. Though enough amps at 36 or 48v could make any motor get hot.

.. I did read up ona specification document the value of I think 52volts as the maximum allowed for on pedelecs. Any of these standard documents refer backwards and forwards to other linked standards and can be hard reading.
I have this distant recollection that 52 volts is a maximum voltage allowed on appliances where there is unlocked cabinets.. above this voltage different safe work practices and safety standards apply. This would have had its origins in telephone comms....

 

[Woosh]

If the G330.350 is engraved 250w then gets my vote.

there is no W after G330.250 and G330.350.
the extra 250W in OEM marking will be reassuring.

This is how the Greenway Maxdrive bikes are marked up - 250W, but G330.350:
