hello guys I ordered 18 wheel Magic Pie and twist throttle for it . I want to know if anyone has got it .If someone knows please let me know how it works.I want to use 48 volt but I don't know maximum amps. I wish to use 12 v 45 amp 4 batteries.
Will I burn the controller??? or will everything melt :o I'm not so good in electric . now I build the first electric chopper . please help. I build choppere moto and bike but not electric I work with metal. when I will recive my wheel then I will take both pictures and video to show you all how it goes. kindly valy

The amperage of the battery is given in Ah, that is Ampere Hour, and means the capacity not the actual current that it will delivery, you can use a 200000Ah battery, no problem, that just means you will have more energy capacity, more range than a smaller one.

you can use a 200000Ah battery, no problem
Bruno, I would imagine the size, weight and cost would all be a problem with a 200000Ah battery.
I suspect that charging it would also be a major problem too! ;D

Valy, I didn't realise the 18" Pie was even available, but it seems it is, 48V certainly won't be a problem for it, as the controller automatically limits the current to to a safe level to prevent things from melting! ;)

I think he means 4X12 45ah batteries in series (48v).
Sounds like hes got some SLA's linned up
Very heavy bike if this is the case.
As said above it wont melt.
And you will need at least a 5 amp charger to charge it up at a reasonable speed.
-
But certainly 60kgs of lead, motor weight, rider and bike may melt the stator insulator on a hot day.
What type of battery are you going to use?
Ooops the PIE is heat protected.
Edit:
If the bike is too heavy, it may run and cut out all the time due to heat.
-
Yep, agreed!
The problem is not the current, but the weight. What type of battery are you using?
Alan: For the 200000Ah battery I did not specified that I will be using 1000 Magic Pies below it! ;D Just kidding, the 200000Ah battery is made of quantum bose-einsten ion condensates and do not wight more than 5g, so it is not heavy... I use them at the FTL core of my bike.

Hello guys!
Dont take me hard .I m very happy to see you interest in my project , but like I said i'm not specialist in electric.
I don't know wich batterie is the best. I need help .
I want too use big amps because my chopper will look like a motorcycle. If I will have problem with hevy batteries maybe I will put 2 motor front and back. will be another problem conection with hand throttle .
Can somebody draw for me an elecrtic wiering for 2 motor.
About the batteries . I have to consult your guys. ;D To buy the best for my project I need links, adresses to see and chose the batterie after the price an needs.
For my projekt I need big amps because i'm a big guy and my el. mini moto will be for crusing and I don't want to finish my batteries over the corner.
I wish to have 1 hour continuosly driving, not full speed, crusing only on the flat .
I saw on you tube big motorcycles with very big car batteries. My projekt will be in between a big motorcycle and electricbike. sorry for my english I'm from Romania but I live in Sweden Kindly Valy

Motorcykel batterier från Biltema skulle nog fungera, bly/gel batterier finns I olika storlekar typ 12V 2.5A till 21A (1kg till 7kg) .
Kolla in http://www.electro-mobile.se/ har också batterier.

The lithium battery has better volts than lead acid (SLA) per KG.
I have 35kg of lead on my bike and it is too heavy. Because I am not overweight it is not as bad.
Yes big batteries on a chopper can work and look gnarly.
The Magic Pie only takes so much current and the rest will make the bike go far.
To much hand turtle (throttle) will make the ride hard with small pack. I don't know about hand turtles, they sound suspicious :D
-
I use them at the FTL core of my bike.
Bruno, Don't you find it very frustrating to have all that speed available and nowhere to use it safely, aren't you concerned that the regen may not be able to cope?
My advice would be to use less throttle, so that other road users will actually be able to see you coming, as your brakes may struggle to absorb all that energy when someone pulls out in front of you! ;)
I guess it really must be a Magic Pie to allow FTL speeds. ;D
Can somebody draw for me an electric wiring for 2 motor.
It's basically very simple, two Magic Pies would share eight common connections:
- Battery + (Red)
- Battery - (Black)
- Brake switch wire (Blue)
- Brake switch wire (Red)
- Throttle control ground wire (Black)
- Throttle control signal wire (White)
- Cruise control switch (Orange)
- Cruise control switch (Yellow)
The brake switches could simply be wired to the respective motor to allow front and rear regenerative braking to be used independently, but this might not comply with legal requirements for cutting the power to both motors when either brake is operated.
Independent brake switches would also cause a problem when the cruise control function is used as you would need to use both brakes to stop front and rear cruise operation.
I presumed you would not be using Pedelec. ;)

hello again and thank you for help. ansure for Alan I don't use pedalic will be to havy to pedal,
-
thank you north if I don't find another option I will go to biltema . but I still try too find beter ;)
-
about brake if must I will use motorcycle or big scooters . to se what is match on Magic Pie
-
haw good they are gel battery ???
-
They are heavy, have low current capacity, last maximum a year. They will make the bike/motorcycle more danger and difficult to handle because of wheight and are very bad for the environment!
They look cheaper if compared with the Li-Ion ones, bot they are not, as the Li-Ion lasts for 5 to 7 years it makes them cheaper for the long therm. At the time you will need to change a LiFePO4 battery for example you would already needed to change the lead acid batteries 7 times!!
Put the numbers in the paper, sometimes you can buy the lead acid for the start and with the economy you have on gas you buy the LiFePO4 later :D
-
SLA Gell batteries worked for me. But I will not buy them again. My last SLA, brand is Ritar SLA/gel battery lasted a long time compared to many other brands I bought.
But Long is 8 mths for SLA compared to years with lithium.
Some brands of 18ah sla I used lasted no more than a month before they were useless.
There is no waist though, I use my spent lead batteries on my evolving home solar system. I have three Redundant 24ah SLA now charged by 50 watt of panels.

Yep, agreed!

It must fit on a fold up bike like this.
(http://www.uberreview.com/wp-content/uploads/backpack-bicycle.jpg)
Cadillac WTF uses thorium to act as a nuclear fuel powering batteries.
How fast will my fold up bike go and how far. Will I need a BMS?
:P ;)
-
ok then acid and gel battery I can exclude them totally.
I will look too find lithium or something else ?.
I would like to put some pictures in this topic , but I don't know how to do it ??? ?
I have same bike projects so so not totaly finished , could I show you the material what I found for this project will be an aluminium frame with steal for ranforsment .
i really hope that someone understads what I am writing ;)
thanks for your help :)

If the picture is already in the internet you can copy the url of that image and put it between "[img ]http://copy_url_here[/img ]" without those "" and spaces
If they are at your computer and are not too large, you can click at additional options below your text area and attach the file!
Or, you can just copy the link to the image anywhere and we click on it to see :D
-
thank you very mutch. I will try.
-
this is what I found... in specification they said 20ah is for 800w motor the best . and for 1000w motor is better to have 30ah . price oooooo :o 787 dollar for 48v 20 amps. for 40 ah close to duble. plus charger. not sow fun :'(
-
this is my dream :o sweds they are good ?
-
sorry the battery price is for pingbattery same 48v-20ah not what is in picture ;D

The only criticism I could give is that pointed weapon thing near the cranks could be dangerous in an accident or to poor unsuspecting animals that may run in there, going at 45kph, ouch.

today the magic is here .mutch disepoiment >:( some pictures

more picture
I don't understand what is the problem with the disc is it for wrong side ??? is coming in side where the chain supose to be. ???You guys can you help me please ???
-
more pictures where you can see 18 wheel inch golden motor is inside the 17 inch motorcycle rim . Is it normal ??? ??? ??? ??? ??? ??? ??? ??? ???.golden wheel look like 12 inch ;D :'(
-
I have many questions ??? .
This wheel is not what it is in the Golden Motor picture. (see the site)
It is better if Golden Motor put pictures of each size of wheel(16,18,20.cast) because they look different,and to write under the pictures . which tire can be fitted in each one of them.
all the parts came with scraches (bad delivery) or....Golden Motors fault.I >:( >:( >:(t also came without instructions . >:( :-\
The cable for the wheel have one cut it's not mutch but I don't like it. (Golden Motor is not good in packing. Next time put some cover on the cables ,and something on the wheel .(plastic cover or something) comming more.
-

Valy, the sizing of motorcycle and pushbike wheels is done differently.
On a motorcycle with a 18" rim, the 18" relates to the tyre bead diameter (the inner diameter of the tyre), but on a push bike it relates to the overall tyre size (the outer diameter of the tyre).
As the Magic Pie is intended for pushbikes, it is therefore measured as per all other pushbike wheels.
I don't understand what is the problem with the disc is it for wrong side ??? is coming in side where the chain supose to be. ???You guys can you help me please ???
You have been supplied with a screw on disc instead of the bolt on one which the Magic Pie requires. It looks like someone has made a mistake with the packing and accidentally supplied you with the wrong brake disc! ::)

Thank you again Alan you are the best :) answer promt all the time.
how do they think too send a disc screewd to a ( rear wheel ) and with hols for disc in a oder side
today I have been in a bike shop and I ask abaout tire and they told me don't have. and don't hire abaut 18 inch in a bike wheel. where I kan find tire for this wheel I whish to have 2.75 or 3.50 if exist for this wheel
(in europe)
-
Nice kit.
Looks awesome with no spokes. Very strong.
Shame about the disc though.
-
hello .
today I will try to start the motor on 24 volt bicause I m scared to burn the controller.
this is the first time when I do this electric stuff . if this works I will put a video online.
WISH ME LUCK !!! ;D
-
hello
my motor it is work .
but when I move the cables the motor start to bip 3 time and stop.
maibe the conection is bad or cable with problem they are to thin very easi to break. I will buy anoder battery to try on 36 volt.
the speed is very slow in 24 volt ,
what is with red buton for the throttle I press on or off and motor is work anyway . for what it is ???
-
Valy, three beeps indicates a throttle fault, check the throttle wires carefully at the connectors.
Check this post for more details (http://goldenmotor.com/SMF/index.php?topic=1626.msg8134#msg8134)
The red button is not connected to anything, but it can be used to turn your lights on and off etc. as long as the current is relatively low, usually used with the LED lights.
You should have two spare wires (a brown and a yellow one) coming from the throttle cable, these are wired to this red switch on the throttle control unit.
I will buy anoder battery to try on 36 volt.
the speed is very slow in 24 volt
Just tested it with 36V and 48V and I will newer ride it with 36V again! Sure it is just 10km/h diffrence in top speed, but everything else is awsome!

hello
I wish to put a fuse on the + cable but I don't know how many amps to put if you kan help me ??? for 36 volt 30amp battery or 48 volt 30amp battery .
my light in throttle is full in 36 volt .this is a 36 volt throttle ??? I don't find tire bigger then 18,2 inch
sombody know if exist ???18 3,50 or18, 4inch.

Thats been a well discussed question.
You have a BMS that should limit the current just above what the Pie uses. If that doesnt work as expected you want 35 amps.
But what makes all this a useless waste of font.
Read on.
There is still is the warning "Important Note: While using regenerative braking, DO NOT turn off the battery". as per GM PDF installation Guide If the fuse blows while braking the controller could fail..
Use a 45, 50 amp fuse just to be safe .
Be gentle Valy.
Set it up. Do not run the motor when not tightened the nuts properly.
-
Or no fuse at all. Seriously.
Do not ride bike unless you.
Make a very good connection. Be sure no thing will interrupt the power connection. Never.
Tape your plugs together. Make good tight wheel nuts and throttle. Check brakes, all connections. Cord leads are out of the way and tied to frame.
When it is all good.
Ride it and enjoy.
-
Do run the motor when not tightened the nuts properly
Leslie, I think you meant to say DON'T ;)
It won't make any difference to the current whether you use a 36 or 48 Volt battery, the maximum current limit of the controller will still be the same.
Mine appears to be limited to ~20 Amps, but some are set at ~30Amps. 21.23Amps is the highest reading I have obtained on my Turnigy Watt Meter, and that was during some steep hill off road use.

Fixed.
Its just one of the early videos circulating around had one man show us how his golden motor worked running it full RPM holding it with his fingers..

in after noon I drive the bike in the tawn 20 km and I I had still 24,5 volt when I come homme
I have only 24 volt because for my son is too mutch 36 volt. hi have only 8 year and hi it is skeard :o
I will put some video but naw I have problem with video codec >:(
GOLDEN MOTOR 18 INCH CASTED WHEEL IT IS VERY ,VERY ,VERY ....SILENT . in very bigg hill make little sound in a full throttle. but with pedal help is no sound ;D naw all my kids want one electric bike : :o my son is very happy 8) ;D
-
Try using adobe premiere cs4 or cs5, it support almost everything. Except foreign codes. Or try decoders on google.
Well hope to see a vid of 24 v :D
-
I have a new canon legria fs200 with 3cd driver but in my computer is work 3-4 sec stop 2-3sec start 3-4sec stop again etc..
