18 wheel Magic Pie and twist throttle
« on: April 15, 2010, 06:47:35 PM »
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.

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.

Bring it on

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.

ps
twist turttle=vrid sköldpadda.

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. ;)

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
