Looking at your ever expanding lines, I'm starting to feel lust...magic pie...48v lipo 12ah, slide on rack, and that awsomely cool 70v. Solar Charger!

My brother's the energy minister here, and is really pushing our province's electric advantage. If I could show him that full set up, he would just love it.

It gets better everytime. Right now we're selling Magic Pie V1, developing Magic Pie V2, but that's a secret.

Hi GoldenMotor,

I wanted to know how quiet this motor is. Does it make any noise at all? Or, is it fairly quiet at startup and then gets quieter at higher speeds?

Thanks,
Ambrose

It's not exactly quiet, it has this soft, high pitched sound, the kind of sound you could hear in a Nissan Street Racing car at high speeds, however it is not loud enough to be called noise, it's more like a mixture of a levitating spacecraft and a sports car.

Hi GM,
what is the no-load max rpm for the Magic π on a 48 volt battery. I mainly want to know how it compares to your HBS-48 motor. Are they all wound the same, or differently as the HBS-48 comes in hi rpm and hi torque versions.
Click to expand...


Currently, the top speed for magic pie is not as fast as the top speed of HBS-48. This is because the pie has higher torque and a 60V limit whereas the HBS-48 has a higher voltage limit, but it won't be able to climb hills at that speed. HBS-48 is not as stable as Magic pie because magic pie has 56 magnets. Please visit this link for more information, or you could view the comparison page, there's an simpler guide to compare in there as well:

http://www.goldenmotor.com/magicpie/features_magicpie.html

It is wound up differently. Our Magic Pie's RPM can be changed accordingly, if you want faster RPM, then you would need to have some volume, at least 10 kits and you can request my manager to do a set of high-RPM magic pies for you.

ORLY ?
According to the GM website the HBS-48 is rated at 430rpm and it was announced on the GM forums that the MP would be 350/480 rpm. I took that to mean on 36v / 48v but are you saying it's 2 different winds ? So is the "standard" magic pie 350 rpm ? on 36v ? 48v ?
I would have thought given the larger diametre of the magic pie being 350 and 480 rpm on 36v and 48v (up from 320 and 430 rpm on the old motor) would have been about right.

Was the HBS-48 ever sold with a higher speed controller than 48v ?? I know alot of people have run them on more, myself included but I've never seen them advertised as such by GM.
 
Ive only read one report on someone melting wires at 48v the whole time and over at golden. It must of been something else because anyone thats going to be melting wires here is my wife and her shopping. No pedals full trip brought home some stuff not the usual. The motor was a little warmer than usual.

The thing runs quiter than an ICE and people think reving the max out of the throttle is ok in comparison.

To run any motor like its an imortal horse and you will end its life sooner.

To GoldenMotor
But at 84v I ask do you think the Pie has the meat in it to handle higher voltages is what the others want to know. :mrgreen: You save em some money mostly anxiety if you do tell. 8)
Edit:
Take da contoller out of it and use your own.
 
...if you want faster RPM, then you would need to have some volume, at least 10 kits and you can request my manager to do a set of high-RPM magic pies for you.
Click to expand...
to buy 10 units is a big ask for most people, can you take paid pre-orders from 10 members instead?
 
Bump.

I will ask again. Can the Pie's winding handle 72v or maybe even 84v over the windings. Many of GM's other products can.

It would be interesting to see how the performances compare to an X5 under the same conditions..
 
Dear members of Endless-Sphere,


Please understand that GoldenMotor will not be able to answer all of your questions. Currently I've seen the issues around here.
1)D2D shipping costs - If you cannot afford them, please buy them from dealers in the future or group purchase in the GM forums.
2)High RPM - We do not cater to 1 or 2 special high-rpm orders, not even 10. I apologize for my staff posting here saying 10 kits would be enough.
3)Full setup bikes - Will NOT be available for purchase online, only from dealers.
4)Magic Pie - If you doubt it, please don't buy it, please wait for reviews or some other video review about it.
5)Attitude - Certain members attitude has not changed at all since the last time I was here, we do not tolerate such attitudes and we will reply with the exact same attitude.
6)Testing and Reviews - Please do not take the $160USD too seriously, there will be Christmas sales and other stuff coming up. The 160USD offer was my idea for allowing professionals to test it out or play around with it. The retail will be at $290USD. So far testing has been good however we do not know if anything else would fail.
7)Badmouthing/business competition - GoldenMotor staff will no longer have the time to be posting on forums. We do not badmouth others, nor do we wish others to badmouth us. We hope people would have the intelligence to see which members are competitors in disguise, which are real professionals that have tried our product, and be able to understand how we are able to prosper in business and increase our sales and revenue, though being called "fakes", "rip offs" and "sucks".

If you have any other problems, arguments or personal issues against us, please tell them to a wall, tell a friend about it or find a psychiatrist.
If you have other seriously business related issues or questions, please e-mail me at yaoyuan@goldenmotor.com.

I am the sales executive, not a punchbag, please do not send me trash. Thank you for your cooperation, the young man, Ben Chan, will no longer be posting here, his internship has ended and he is going back to school with an A+ grade. His attitude was adopted from me. If you don't like my attitude or my ways of customer relations (most of you are not my customers anyway), please go report this to your local police station and hopefully I will be jailed for being rude to online anonymous users who do not even post their real names.

*Personal comments: Some of you are professionals, nice guys and potential clients for this business. Some of you have no jobs, no education, no money but still feel the need to flame on this forum. I don't really consider this forum a big market, however I do not know why the promotion was posted here. I will only give this offer to professionals regardless. I still have a bad image of this forum, and do not try to tell me that my bad attitude towards this forum was due to my personal nature. Do not try to speak up for the people who have been rude and nasty towards me, I base my thoughts on first impression. I believe in fighting fire with fire and I get personal if you get personal. For the people who read this, and think that this will lead our company to destruction, please do understand that eBikes is a very small part of our company. For potential dealers who have read this and think that this will put you away from doing business with us, please read through all posts and the replies of this username, I believe everyone has self-respect and the rights of self-defense. I am the man that kicks the dog after it bit me.

Sincerely yours,

Yao Yuan
Sales Executive
GoldenMotor Technology Co. Ltd

Yes, give Ben an A+.

Don't take the flames personally. We know who the good guys are around here and we can ignore the others. There is a very low BS tolerance here, so stated specs will be put to the actual test to verify.

As rough as the Sphere may be, it is a place where you can find out what is actually working and where the weak points of designs are. In fact, I suspect a lot of the testing done by members has resulted in improvements in designs that benefit both manufacturers and customers.

Personally, I thank you for posting on the forum so we can get an insider view of things in the making. I especially appreciate someone with a sense of humor.

Now I'm just waiting to see the pictures of the insides of the pie with ammeters and programmer interfaces attached. That's what we do here.

Agreeed, thanks "GM" for comming here and sharing. Please dont hesitate to bring any other products to all our attention in the future. Flamers are everywhere and you dont need to come to ES to find them, you could find a bit of flame on your own GM boards as it was left unmoderated for too long, things change and I feel your rep here has done extremley well in the face of what some call deserved adversity. GM has made some huge efforts to make amends to the problems some have experienced and should be given credit for that effort. However GM and their reps must understand these efforts will take time to take effect so do please be a little patient.

On behalf of most ES members I dare speak up to state our overview of this whole interaction with GM and the Magic Pie has been a positive experience and has hopefully led to better sales and success of the Magic Pie.

Good luck in the future.

We do appreciate the give and take we have had with GM on this forum. We realize some of the earlier complaints were by people buying from e bay and not from GM. Some for unrealistic shipping demands. Please don't judge all by the actions of a few. We would't judge GM by your short temper caused by pressure of your position at GM.
Good luck on the launch of Magic Pie. May GM prosper.
 
Glad my Inet connect just came back on.Is it a cowpie? If Hyena was "paid" for review,I can't wait for general customer response. the Pie must run on "bio fuel".The whole project is,well "Chinese vague".Special group price $290-Slow boat from china shipping"dirt cheap"$130.etc,etc....Might wait and pick one up at the salv.Army store come spring breakup.

Click to expand...

I assure you I was absolutely not paid to do this review.
Like many of the members here I'm an ebike enthusiast and did the review out of my own curiosity and for the benefits of everyone else who is interested.
I have another GM motor which I've been very happy with but I'm by no means a GM fanboi and if something better comes along I'll buy it.
I've been a member of this forum for a while now and if you search my posts you'll see I'm not a secret GM spokesman taking a different approach to the others that have visited here!

I've been keenly following the development of the magic pie out of my own interest and was pleased GM has allowed me to pre test one before they're made available to the general public. I believe others have had them for testing too but have not posted their findings,most likely because they are still a work in progress by GM (although now they're going semi-public). I don't doubt that the final or future versions of the magic pie will be tweeked and GM would be wise to take onboard the comments and suggestions from the many experts on this forum and their own.
 
fisrt up thanks hyena for your review,
sorry to hear you didnt get the speeds that golden motor claim (48v 48kph)they get with the pie.

& i would bet my bottom doller that he DID NOT GET PAID FOR THIS REVIEW.maybe if you had inquired to(i did)about getting the magic pie prior to its release date.you wouldnt say such things(to who ever thinks he got paid)....


hope it works out for you hyena
 
Hi,

Slow speed problem is being solved live.
http://goldenmotor.com/SMF/index.php?topic=1411.msg6842#msg6842
 
Sure, speed controll is what the controller does, and the manufacturer can easily make adjustments to that. Obviously the NA customer wants it illegal fast.
 
It wasnt just that it was going way slower than my GM at 60v and it was drawing the same current.

Why buy the big expensive hub when the little hub next to it runs better? The only thing it seems to of improved upon is the startup torque, not needing gears sounds like the bonus is my take on things.

Some wattsup will uncover the whole truth.

Edit.

Choice is better than no choice.

Not all bikes are made for on road use.
 
I went on line last night to order 3 pies, 2 batteries and an extra charger, and requested a price to ship via "snail mail". In spite of what GoldenMotor said earlier here, there doesn't seem to be any point in the "snail mail" option, as I was quoted $700 shipping (in spite of the shipping quote generated by their site of $640) ah, well...I couldn't really afford them anyway. I was going to have to put them on a card and pay them off over 6 mos. Maybe good kharma is looking out for me...

Leslie it doesnt draw much current, I was purposely trying to make it draw maximum current to see what it was capable of.
Cruising along it was only drawing 5-10a

Bob if you make the payment then email the sales dept they will adjust the shipping charges and refund you the difference, that's what I was told anyway.

Explains the 200 watt feel of it. The added torque on the start up must be a nice change for a gearless.

I have no idea what my GM hub draws I'd say the same, but that clarifies a lot somewhat and that this was not 60v was more like 54v by old school batt ratings from SLA days.

I'm not looking for this to be an overunity magic motor, You cant pull a rabbit out of a hat.

You have been very honest in your representations and would like to see a lot more in the future.

This should not be the case, Who The Pie quoted you that price?
Please e-mail nickshen@goldenmotor.com and he'll quote you a more reasonable price. However I think you would need to sea ship more than 6 kits. If it's okay with you, you can pay for the pie first, without the shipping cost, take the receipt and when we find suitable people to group ship to you, then we can ship it out at a lower price. And it works both ways, if you think it's not worth shipping then you can just request for a refund from paypal. The point of you paying first (Alot of people is doing it this way) is so that you already own the pie that's lying in our warehouses. Then when a suitable group shipping is found, we will quote you an average shipping cost and introduce all parties in the group buy to each other. One of the person in the group buy will become the Organizer, in which we will ship directly to his place. And the rest of you can pick it up from him.
 
Thanks for the follow up. My problem was created by ordering some batteries with this, and GoldenMotor can't send them via seafreight, so $680.00 US is the best they can do for shipping.

Something wrong with your battery hyena, the magic pie you got is the HIGH RPM version. Which is basically the magic pies that's going to sell at 160 today.
Click to expand...

GM, can you please clarify whether or not the high rpm version is available for general consumption.
I decided not to buy on the sale day because you said we could only get the slow/hi torque version.

Thanks.
 
Dear oldhaq,

Let me clarify certain issues.

3 type of magic pie:
1)Euro legal, slow RPM, highest torque (Hyena's magic pie)
2)Euro Illegal, high RPM, high torque (What was sold on the first day)
3)Euro Illegal, SUPER high RPM, LOW torque, Matt surface finish, Magic Pie GEN 2, (Development in progress)

What you were supposed to buy on day 1 was no.2. What was sent to hyena by mistake was no.1. What you intended to buy was no.3.
I guess many misunderstood the meaning of high-RPM. Also, please do not tell me to cancel your order for no.2 so that you can wait for no.3.
Because for every No.2 magic pie owners, you can quote us your serial number and you can get a GEN 2 for 50% discount.

Best Regards,
Yao Yuan

Hi Yao,
It is good that GM strives to perfect a product and there is more development in progress.
But if type 2 already gets 50 km/h (30 mph), why is it we need to go faster?
On the other hand, making the motor as silent and efficient as possible should benefit everyone.
Or how about a digital SOC (State Of Charge) indicator?

Anyway, keep up the good work and thanks for being here and sharing.
