Magic Pie III Updates

[GM Canada]

Before

Townie 8 Speed with internal cabling. The cables run inside the frame for part of thier run.



After Conversion.

Added two Internal Magic Pie 3 Motors, a rack with three batteries, lights and a Cycle Analyst. I Built this bike once with my first two pre-release MP3 Motors. It was a quick build with little effort to keep the "clean look".



Then I completly stripped it when I received my second set of MP3 pre-release motors. Since the wiring harness has changed nothing is compatible with the frist two motors so everything had to be replaced, motors, levers, buttons, trottle, etc.

This time I took alot of care to give it as clean of a look as possible. I routed all the wires through the frame along side or the original cableling.

I think it turned out pretty good and I absolutly love it!










After looking at that last picture of my bike I can see I should level the battery rack as it was before. I think it looks better that way.

That looks great Gary, that bike looks clean. I definitely won't be using my Magic Pies until the spring we just got 20cm of snow and its -18C out right now haha.

Thanks Paul,

We were supposed to get 2 inches last night and 2 more today, Nothing yet though, it all seems to be missing us so far Next week they are predicting above zero celcius temperatures again. More rides to work in January, Woohoo!'

My fingers and toes are crossed!

What the weight of the new Magic-III. Have it becoame heavier than Magic-II?
What's weight of the Magic-III for 16" wheel (rear and front versions)?

[GM Canada]

According to the promotional material the MP III Kit is 11 kg. I don't know what the various sizes are in weight but I imagine I'll be weighing quite a few shortly.

Magic Pie III Arrives in Canada February 6th! 

With rail time and customs we should be shipping by Valentine's Day!

Although this order is quite large we also had many pre-orders and a few sizes are out of stock all ready before we even receive it.

If you want your slice of the pie order without delay. Don't miss out!

"According to the promotional material the MP III Kit is 11 kg" - is this including a battery of 5.5kg?
"I'll be weighing quite a few shortly" - look forward to for the updates

[GM Canada]

No this does not include the battery. Also the battery weight is more like 8kg the 5.5kg I do know when I ship a MP2 kit with battery the sealed box weight is 20 kg.

Waw! Just a wheel with a controller weigh 11kg! Whole my bike weighs 12.5kg! How is the kit so heavy? The Magic-II wheel's weight is just about 7.5kg (according to GM site). Is the new controller weight 3.5kg? Too heavy... How so? How many Amps can it provide in peaks and during a continuous operation? Anyway, with such weight, it seems to me this kit is not for the mountain bicycles...

[GM Canada]

I don't make them. I just weigh them.

If you are going to believe everything China says you will be mislead quite often.

I did a lot of tests and uploaded many pictures and links to videos on the MP III into this thread. Most of the information anyone would ever need is in this thread already. On take off the peak watts is over 1200. Once you get rolling this drops like any other motor.

If you don't understand why a Magic Pie 2 is 10kg then you obviously have never had one in your hands. If the MP III is 11kg then so be it.

Most likely these numbers are the shipping weight anyway.

Even the Pro 901 boxed up to go is 9kg. What motors do you use and how much do they weigh.

Gary

The Cyclone's 1200W (2500W in peaks) kit weighs 5.5kg. It's not a hub motor, but a mid one.

[GM Canada]

Sounds like you are compairing apples and oranges. They are not the same.

Gary

[Just]

apples and oranges... the key is performance!

[GM Canada]

True performance is an important factor. But there are others. One motor is shaped like a car starter and the other like a pancake. Lets not forget why the Magic Pie was invented. It was designed as an all in one simple to set up kit. If you have seen my unboxing video of the MP III you can see how simple it is to hook up and how few wires will end up strung along the bike. The Magic Pie III gives it a simple clean look. In most opinions it is a startlingly attractive look as well.

I am also sure you have read many threads on the performance of the External MP2. if you  Run with our external controller it is a perfect match for most riders. It is also great for running with third party controllers like the Speed junkies do over as ES. Some are running them at 5kw or even more.

Don't forget the weights I am quoting you are packaged shipping weights. If you subtract the box, the rim and the spokes I am sure the weight is much less. I actually have never weighed most items individually. Just the total box weight. I will keep this in mind and try to determine some exact weights in the future. I would assume a box and packaging could weigh a kg. A rim a little less then a kg. The spokes seem heavy too.

There is a direct relationship between weight and power.

I don't mean power in the electrical sense they
cite talking about the motor, exactly.

In order to accelerate my lard-butt from zero to
some speed you have to apply torque.
You can increase torque in two ways.

1: increase the moment arm of the motor
    (with a larger radius to the magnets) and
    increase the structural weight and
     rotational inertia.

2) Use gearing to increase take-off speed then
     change the gear ratio to get speed, at a cost of
      more noise, complication, and frictional loss of
      power.

I prefer the simplicity of a direct drive, but that is
just how I roll.  A 116kg doesn't worry much about
 5kg more to get extra power.
