Nice photos on the site. It looks like the axils are round. How is the torque controlled?
Title: Re: Magic Pie 20/10/2009
Post by: Hyena on October 15, 2009, 11:42:22 PM
Yes I noticed that too. I would have thought with the extra torque of the MP and with the added stresses of regen braking you'd want to do everything you can to prevent axles spinning in the drop outs.

In the kevin netherlands Magic Pie thread though it shows the flat sided axles like the old motors. Is this another difference these '1st day' motors will have Yao ? Flat sided axles and old style wiring connectors ?

Also can you give us an indication of the shipping prices for 1 or multiple motors by sea ?
I've been rallying interest in the MPs and have rounded up a few people here in Australia who are keen to grab one if a good deal can be had by combining shipping. GM is giving us a good deal on the motors but it hurts having to pay almost the same again in shipping, and it's dead money to both of us.

You can sea ship it. Dirt cheap.
The axles are new. Wiring connectors for kevin were old because the new wiring hasn't been manufactured when we shipped it to kevin, if he want's the new one we can just ship another set to him. For shipping quotes, you need to contact TOM personally.

Post by: e-lmer on October 17, 2009, 07:47:30 PM

Technically I would take off half a point for using
'the flats' as an answer to 'the device'

The question is flawed, since the machined flat sides on the axle
is/are the correct (tho partial) answer.

A superior question would have been:
With reference to Question 2 above, please complete the following sentence:
The machined flat sides of the axle slide into corresponding slots on the forks
or frame to______________.

Where the best short answer would be like:
  "prevent the axle from spinning under torque."

Any allusion to the flat spot on the bottom of a trebuchet  gain extra points.

How do we contact Tom "personally" to find out sea shipping prices?

Maybe you could find out for me the cost of shipping to Florida, USA?

Dear Yao,
Congratulations you've made it through to the bonus round.

Part 1: One of your guys on another forum posted about the MP saying
Quote from: GoldenMotor
Currently, the top speed for Magic Pie is not as fast as the top speed of HBS-48

According to the GM website the HBS-48 is rated at 430rpm and you posted a few months ago that the MP would be 350/480 rpm. I took that to mean on 36v / 48v but are there actually 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.

Part 2: Are motors for different sized wheels wound differently ? eg. are MPs laced into 20" wheels higher RPM units than those laced into 26" ? Or is a 20" wheel slower but with more torque.


Please do not answer in pencil. Use only a blue or black pen, or a keyboard

Note!: Answers must be answered accordingly so that it looks like an answered answer.
Type your answers clearly, marks will be deducted if the font is too ugly.


Answer:
Part 1 and 2:
I believe that was the internship guy.

Top speed does not mean average speed. By top speed I mean the highest speed the motor can ever travel at. That's when you put in 100Volts of pure electricity into the motor with a controller that allows it. If you are talking about top speed at the same voltage, I'd say Magic Pie is faster provided they are wounded similarly. However the current Magic Pie is wounded in a way such that the RPM would only be slightly faster than the HBS-48. This is to ensure that the First round of Magic Pie does not fail under ANY circumstances. Because you cannot put in more than 60V of electricity, hence it will not burn and the wires will not "melt", we use the word "melt", but it actually means that the controller wires inside do not burn. Then, we would make Magic Pie V.2 which would be at a higher RPM. However this information is not supposed to be out here in this forums so please ignore anything I just said. Quotation of this sentence is an offense and offenders will be offensively offended through use of offensive offense. The main point is, after we can ensure the quality and stability of this technology, then we can come up with new stuff such as Magic Pie HS (High speed), Magic Pie Li (Light version for the 20", 24"), Magic Pink Pie (For the ladies with colorful decorations and a lower speed). These names may sound stupid and somewhat erotic, according to articles I've seen on other forums, however stupid names work well, look at the words "Google"(what?), "Hermes"(Herpes) and "FCUK"(You know what).

The speeds are different. Right now we have only 26" 28" and 700C. We are currently unable to do the 20" 24" and the 18". However do not worry because cast rims are simple as pie. Then we would have a final version of Magic Pie Pro which has a super-intelligent controller that allows users to modify their top speed, the controller firmware, the acceleration, the different speeds for different rim sizes and last but not least, be able to connect to either a Cat-Eye or your favorite Watts Up meter, displaying numbers which matter to many eBike enthusiasts.

Marks: many many

Post by: neptune on October 19, 2009, 03:32:12 PM
All these posts make no sense.Are they "inside"jokes? Are they at our expense? How did the "heyena" get his MP kit already?I've read his posts and he was asking many of the questions I had.I have been visiting daily to get answers.One question I asked was whether MP could be ordered and paid for in advance of the 20th debut.I never recieved a direct answer.I also EM'd the sales dept.at least a week ago.- no reply.In the U.S. we expect fair and equal treatment in business dealingsCan you just print the cost of "slow boat from china" shipping to the U.S. so in case I don't get a reply EMing "tom" in time to make a decision I can order on the debut day? Are you one day ahead of the USA timezone wise?It's getting close and since my previous dealings with China have been at the least, confusing,especially around your holiday seasons,I don't want to be told "you missed the boat".Thanks for your care and concern.

Hi Neptune,

I noticed questions were being asked but the required answers were not being given. So I decided to try a different approach.
They're not inside jokes, just a bit of light hearted forum fun, an attempt by me to get a direct response and hopefully direct answers which we were still waiting for, and it appears to have worked.

If my warped sense of humour has caused any offence or confusion, please accept my apologies.

Neptune, my motor was actually shipped a week ago, it was just a bit delayed getting here.
The purpose of me getting it early was to do an unbiased review for the rest of you here, and the ebike community at large. I'm not the only person to receive one early and if you have a look around other forums you'll see it's fairly common practise for manufacturers to supply their products for review and testing.

So Yao, today is the day ?
Title: Re: Magic Pie 20/10/2009
Post by: GoldenMotor on October 20, 2009, 01:54:58 AM
Dear All,

Today is the day!
Hyena, your reported speed limit might be wrong, please try it with our GM batteries in the near future. It should do 35KPH at 36V, 47KPH at 48V. I guess it's the battery problem. Those were High RPM Magic Pies you got.

Dear Neptune,

Jay has been in contact with me for a long time already, don't worry he's paying the same price you pay. Today is the day, we're going to extend the offer to 32hours due to GMT time lag and for a customer who's loved one is in cancer operation. May we wish him all the best in his operation.

Hi Bill,

I asked Yao the same question earlier today, it seems that only rear kits are currently available.

He says the Front wheel kits will be available at a later date.

Title: Re: Magic Pie 20/10/2009
Post by: bcable on October 20, 2009, 12:39:54 PM
I hope we will have a chance to buy the front wheel package for the $160 price when it is ready. I can not use the rear wheel Magic Pie on my bike and have been waiting for this release. I believe it was stated both would be available and for the same price. I understand that there are lots of details involved for this release and I can wait until the front wheel package is ready. For me the riding season is about over anyway.
Title: Re: Magic Pie 20/10/2009
Post by: GoldenMotor on October 20, 2009, 03:37:55 PM
Relax...
I am not a bad person.
There will be a 48hour 178USD Magic Pie front wheel soon, the moment they come out fresh and delicious from the oven. I will post updates on this. If you would like to be notified of this event, please request it and send me an e-mail yaoyuan@goldenmotor.com.

Also, I've seen the dull atmosphere in this forum and BikeMad's having time to sleep and laze around. I will soon post a link for Group Purchases and the GM Forum on the main website, then it will get noisy and all chitty chatty in here. Then BikeMad's going to have the time of his life. Also it solves the problem for group buyers and those who wish to get products at a lower shipping rate. Although the shipping has been reduced to 150 (It was a 11th hour miracle that we got to sign a deal with EMS), I still think the time will come where people would just buy from our dealers. I will ask (or force) the dealers to be active in this forum soon. More company for you guys.

I already own a golden motor kit and was looking forward to this release to buy a second one to get my wife involved.   The 150.00 shipping is pretty steep.   I'm not in a rush for it but there is no way to indicate sea or ground shipping.   Any idea how I could do that.
Title: Re: Magic Pie 20/10/2009
Post by: GoldenMotor on October 21, 2009, 02:40:24 AM
You would need to have a minimum 6pcs order to ship it by sea.
If you do have 6 pcs, or a group of 6 buyers, then send an e-mail to nickshen@goldenmotor.com for him to quote you a sea shipping rate. You can still get it at 160USD if you do this within 4 hours.

Hi Yuan

I owned and sold an HBS36F 20 inch and was very content with it. The speed it gets from a 36V ping pack is about 23kph, which is sufficient. We use it to power our cargobike: (http://www.workcycles.com/workcycles-bakfietsen-images/bakfiets.nl-images/bakfiets.nl-cargobike-long-420.jpg)
note: this is a sample picture.

Since my wife will have another baby in three months she really enjoys the electric assistance, because these bikes are somewhat heavier to use.

Recently we sold the bike with the electic motor and bought a bigger cargobike without motor. I want to repeat the steps an know if it makes sense to buy the MP. Questions:
- will it have the same top speed and torque?
- are the brakes more sophisticated? The old electric brakes are all or nothing, so its a bit uncomfortable to use them.
- will you manufacture a 20 inch version of this MP like the HBS?
- I just returned from vacation so I couldnt be online on the 20th of october, do I still apply for the 160 dollar promotion price?

Regards,
Johan (the Netherlands)

Sorry, but a promotion has ended.
Top speed is the same, but stronger torque.
The 20 inch depends on the demand for it.
Brakes remains the same.

Not now. Well the first day response was good, our dealers are attracted to this new product as well. Hence we will throw funds into the full setup bikes and the intel controller. However you have to give it time to develop a USB cabled Magic Pie.

How about that bluetooth throttle?  ::)

I think MIT Greenwheel is using one, but that is just a concept at the moment :)
Title: Re: Magic Pie 20/10/2009
Post by: Bikemad on October 22, 2009, 08:59:01 AM
How about that bluetooth throttle?  ::)

The throttle controls are connected by wires as Bluetooth testing was not successful. When the Bluetooth battery was low, the motor cannot receive any further signal until battery was replaced.

If the throttle device transmitted the bluetooth signal for a split second, but only when the throttle position varied, it would greatly prolong the battery life. At a constant speed, no signal would need to be transmitted until the throttle is moved to another position.

The throttle could have a reed switch or similar which would disconnect the battery when the throttle was fully closed to ensure maximum battery life. A small capacitor would enable the throttle to send a last "no throttle" signal before it was fully discharged. Simply moving the throttle would automatically reactivate its position sensing circuitry.

This would work similar to a wireless cycle computer, which only sends one tiny pulse per wheel revolution instead of a continual signal.
Their batteries usually last for ages, unless you're unlucky enough to park your bike with the magnet right next to the reed switch.  ::)

A "low battery" signal could be sent to the controller, which would then beep regularly to indicate that the battery needs replacing.
(like smoke detectors)
You could possibly switch over to a built in emergency battery or have a quick charge option using the hub's usb connection?

I'm sure GM could turn the prototype version into a completely viable product with a bit more thought and development. ;)

Yao,
You should forward these comments to whoever deals with your design and development projects, and then post a video response.
I think I can guess the response already.

Imagine this:

You are cruising at a speed of 47KPH on the road one lovely morning. Suddenly, the blue tooth fails, and you are unable to send the "STOP" signal to the bike. Panic? Reach behind to twist the keys? Boom. That's why no bluetooth.

Post by: e-lmer on October 27, 2009, 11:42:56 PM
To be fair, the 'no signa'l state for bluetooth should be
"Off" not previous/current state.

Still, that leaves you with a dead bike to push home.

Something different, however, could be something like
(but not) X-10, where a high frequency oscillation in
the frame is modulated by the throttle control and read
by the controller.

The whole problem is that it violates the K.I.S.S. principle.
(Keep it simple, stupid!)

True.
Frequency oscillation in the frame sounds cool, but as you say it needs to be kept simple, and for now that means going with a proven methods. What ever you use will result in a failure of some description sooner or later, be it flat batteries or a pinched wire from dropping the bike or what ever.

I got stranded in my car one night with a snapped throttle cable. I managed to get home by collecting the all the shoelaces from everyone in the car, tieing them together with one end on the throttle body and the other end fed through the driver window and controller by pulling on the string. It wasn't ideal but we got home  :D

Perhaps I shouldn't have removed the new topic 'tamiflu for sale PV2', as it sound like you could do with some.
