That was a good experience. I am relieved it went so smoothly.
Gary Salo at GM Canada is offering $50 off the MP 26" rear Pie as he has excess stock. $100 off for two Magic Pies. Awesome.
All internal controllers MP's Me not fussy.
I just emailed him and he sent me a link. Tried to give me a free $140 CA instead of the $100 off but my wifey put the brakes on me.
I forgot about the currency exchange and had no idea of what shipping to Australia was going to be. For the two MP'S all the way from CA it was not too bad. Just had enough in the end.
GM Canada web ordering system with the personal touch Gary puts into via Email makes real shopping seem difficult.
After he sent me the order link I was pleasantly surprised by a full list of my order and with a picture of all the parts So Impressed I took a screeny of the order page.

What do ya think of that delivered from Canada to Australia for $813.00 USD? ;D
LOL I cant wait. Ive been waiting for MagPie ever since they advertised these hubs on ES way back when. The Australian version of the Magic Pie is a MagPie. An Aussie black and white bird that swoops from the sky and and attacks all in its territory. Perfect.
Thanks Gary.

Thats a pretty awesome deal! Gary is the man. So what are your plans with two rear pies?
-
the pie is fantastic. No probs so far on mine. you will be (are?) happy! nice humor as we say in .no;D ;D.
-
My Pies have traveled to the west side of Canada, Id say ready to board a boat.. Looking forward to their arrival thats all.
No need for me to get excited, another maybe 4 weeks to go. ::)
-
And you can't get excited 'Big Kev' style anymore these either Les... ;)
I'm still certain you are thinking of your pies before you went to sleep at night.. I was!! LOL
-
I was wrong the Pies traveled up the road. >:(
However I just tracked them now.
International item has left Canada :o :o :o :o
Now I will never get the sleep I need tonight. ::)
;D

Called Aussie post.
They tell me up to 3 mths to deliver by sea mail.
My 2 X 48v batts will be shelved for more than 3 mths now. Not good.
2 MP builds are now a distant memory and a haven for my on going frustration..

Let's hope it will be a lot less than that.

A pair of Swedish fingers is also crossed for a near day of arrival. But if you rather would like a Swedish good-luck, I can “hold the thumbs”.

What? they told me six weeks here, I think its past that now. Ill call Canada Post tommorow! I might be able to find out what boat it went on.

Yes it should take 6 weeks at around a maximum, especially from our sister country hehe
I'm sure those pies are still nice and fresh ;)

Hey thanks all. You do make me feel better.
Yes Gary what they say in the web site at CA post is prolly for shorter trips. You can only tell me what they tell you. I don’t feel mad at you Gary, I just felt Mad. I would of rather been told three months 7 weeks ago. No need to trouble yourself just yet. Its good to know you’re willing to help things from your side Gary. :D
Haa I had about 6 hours sleep last week. I took two sleeping pills two days ago and got some sleep at last. Been living on caffeine. I gave up those energy drinks a few weeks ago. Been up and down like a yo yo now on coffee.
The V energy drink helped me through raising the three little ones and gots depressed with out the excessive doses caffeine. Seemed to of got myself into cycle. Life style change is needed and its not so crucial I stay up till late making sure they are all a sleep.
Broke a third BMS Grrr, precharge circuit failed and I had to fiddle, should of used the shrink wrap with BMS sitting in the alloy box, planned on heat paste glue the fets non conductive part of the packages to the aloy box. Was looking good, but small arc, and BMS no more. :(. Still have the 15ah pack working.
Building my own three stage BMS now. Zener diodes 3,3v 3,6v @ 1 watt and 3.3v 5 watt with .5v drop diode 3.8v total, with 16 X 3v coil sugar cube relays that can switch 17 amps I use these to isolate the BMS when the charger isnt connected,. It wont bleed unless its connected to the charger, meaning no leakage when resting. and looking at 1.5 amp balance bleed current. 75% balance regulation on the 2 amp charger and 35% balance reg on a the 5 amps charger should see me land a perfect balance on a single bulk charge.
Also made a single BMS module out of an MPSA14 transistor today that was doing 600ma @ 3.8v and 77ua at 3.2v.. I might use it in the shut off and single cell LVC Im thinking how I can include this into my design.

Am proud to announce I received most of my order today. I am still waiting for the rims.
Canada post and Australia post delivered my two out of three parcels, no bumps from customs or Freight companies,. Good service,
The packing was decent and the Pies were in good order. First thing I did is take a pic of the boxes open bar 1. Everything that was supposed to in those boxes was all accounted for.
I was going to do a video and but to be honest I didn’t feel too happy about missing one box in the pic and thought it would be wise to concentrate on the working build.
Unbelievable. I was impressed with all the products but suffered from the USB cord pulled half out wires exposed thing but it still worked.
Easy to connect, I just installed an Andersons connectors to the cycle analyst shunt and it was ready to connect to the pack.
The CA stand alone tacho cable is thick and durable, just fine for the job. The throttles are good quality for full hand throttles.
The cables are long and I like the connectors, I should avoid needing tovclean them or poking something in there, they should to fine. When I’m done I will insulate tape them or even use heat shrink the main connector plugs.
Set both wheels at
17 amps cont
20 amps max
120o
PAS NA
Speed scale 100 percent.
Motor voltage 48v
Mode NA
Speed Scale NA
Regen 0 percent
No rims so I took a look around and I saw my old steel rim but it just seemed to bendable. Would be good with the longer spokes. I think the deep V rim is going to be better as the are more rigid. I will just wait..
Thanks Gary Salo from Golden Motor Canada. The deal was worth the 8 week wait for sea mail, and Gary is a pleasure to deal with..
-
Good to hear your pies have finally arrived, let's hope they will soon be reunited with their rims! ;)

WooHoo! I can finally sleep at night again!
I wonder how the rims got seperated. I hope they didn't somehow miss the boat. Thats a scary thought if they are coming on the next boat. The one concern I had was whether I got the motors packed tight enough together. I don't exactly remember how I did it but I know I tried. I'm sure the box of all the controls turned out ok. Dont worry about the wires on the USB cable they are unused extras and most of the cables look this way.
Hopefully the rims will show up in the next day or two. If not let me know and ill try to find out something. Last time I tried I was told they will be 6-8 weeks and if they don't show up call us back. I have since found a form I can fill out for tracking missing frieght. I will need to know which tracking number you did not receive. The numbers should be on the boxes.

Goit the rims. They are not super but strong and reliable. BTW don't take that GM sticker off, some thing to do with the join it looks a bit hmm under the rim stickers..
LOL Guess what.
Damned GM controllers. :D I did expect anything more than everyone else gets here and thats what I got..
First hub pushes 300 watts. The software works and no change even set at 50 amps.
I made no mistake. Tried it on a 20 ah Lifepo4 with no BMS. No swich just straght from pack to Pie. No sparks or smoke.
This one has to be investigated. Im not sure about the other hub though. Im going to put the rim on it and try it out.
The CA works good as does everything else bar the 300 watt motor. I'll get a new controller for the 300 watt hub.
I got $100 off for both Pie's and a free CA so I more or less got these internal controllers free. I suspect its a 200 watt EU legal hub. We will see if I can do the bypass mod, it maybe easier to take the side off than spoke the other hub..
-
Actually I have what is considered a fully legal road PAB and beginning to warm to the idea. I think it will do ok with the speed at 48v and like my 20 watt bike be ok for the shops..
Ill run this around for a little while so I can get some stuff done on the other hub like tires and thngs and run some circles in front of the law and let them sniff it out and show them the CA if need be.
-
Above I just did a stop stand test by throttle and holding it still I could only get 300 watts.
I just took it for a ride.
:o :o :o :o :o :o OMG
I was pulling 880 watts.
I must of pulled some stunt as the CA says max speed 589 kms but I averaged 35kph. Top amps 20 max.
-
I just took it for a ride.
dude it's like 2am in QLD now, even later here!! haha late night pie snack huh?
:)
good to hear you got your wheels mate - keep em spinnin
-
I havent even got my lights on but the wife tells me wind resistance is low tonight. ;D.
Gary tolds me on hub only went up to 20 amps and Im fine with that for the smaller 15ah pack.
Just some wire clean up and reset this back to my settings and this bike is finished. Ill keep the 15 ah pack on the 20 amp motor leave regen at 0 percent and see how long it lives for.
Thanks Monkey, BTW that solid state relay isnt doing too bad. ;D
-
Whew! glad to hear the rims arrived.
When I tested those hubs one was about 20 amps, the other over 25. I tested them without using the USB software. Try testing the second hub without saving any parameters in the USB software if im not too late. If they have had the parameters set already try setting it back to 24 volts to see what happens.
Gary

Took for a 20km trip and used around 230 wh and about 4.4ah leaves me with about 10.6 ah pack. I put it on the charger for 10 mins I had to rush out again. That was awesome not to have to wait for the old SLA's to charge up enough.
What wattage are people pulling on take offs?
This hub has no balls on take offs but unlike the other hubs, if you have got a bit of speed it will accelerate with plenty of torque up hills. My Pie seems to have a lot of top end torque.
Maybe a little limited on the shunt solders making it good at chopping phase voltages and delivering the torque at high RPM when hall events are many.
I am impressed with the efficiency but seems to use a lot of power to keep its tops speed. Going up hill at top speed is good. Even limited to 15 amps cont 23A max top speed up hills is very nice.
-
I spoked the second rim and used the tune method. I did half of it not even looking at the rim It almost came up true.
The spoke pattern is the best Ive seen and ridden. Very strong. To say the spoke don't need to be tight would be a little strong. More like you don't need to turn the nipples to many turns to get good results.
Being a narrow rim the deep V rim makes the job solid and I feel very confident all spokes are going to hold strong and live a long life. .
-
I really have to try spoking a rim someday. Everyone makes it sound so simple. One thing I can say about the rims I have hit some serious potholes and there has never been an effect on the rim. My coffee has gone flying and things jump out of my pockets , but the rim still hangs in there.
And yes I've embraced the Picture, at least for the time being. Thank you for that. Where did you find it. My wife is asking how do they know what you look like? Somehow when I look in the mirror I don’t see a super hero. Maybe if I actually put on the outfit, say Halloween is coming....
Gary
-
that's funny as
Gary do you have a cup/drink holder? I don't and I learned the hard way you cannot carry a coffee and operate a thumb throttle pretty much at any speed.... The details of the story were grim... but I can't stop laughing thinking back on it
I think everyone should try it once haha
-
Sure I do. I use it strictly for coffee in the morning, no fun drinks! ;) I have a steel mug with a screw on top and a hole with a snap down and popup lid. Its the only way to go if you don't want to get sprayed on the big bumps. The reason I have it is so I don't try to hold a coffee in my hand while driving. Its not the throttle I'm worried about its the regen. If I hold the bars with just one hand and touch the brakes the regen leans me forward turning the bars. I learned quickly holding the bars with one hand while cruising at 32kph is a bad idea. I did not have a bad incident though, just a quick warning to wake up! :o
Gary

Im done playing wif the software this bike is fine, The new 24v settings at higher amps is giving me good power. Still a little slow on take offs but I can push 800 watts.
For an internal controller and 15ah 1 C pack Ill be happy with this.
Im going to keep regen disabled. Both of the rims front and back are sooo close to perfect and when I brake its smooth ice but effective.
About 42kph top speed and I'm happy with both hubs.

Looks great Leslie! These pictures were a long time coming. I hope you are happy with the result.

I got some older pics but they were a little dark so I waited for day. Plus I wanted to submit a pic of the bike when I decided it was running and looking stable.
I had to dig up an old project box to put the long leads in there and get some plastic ties, Still a couple of things to install. Like I waiting for a p7 12 watt LED,
Yes Im happy with the results, This is the best E-bike Ive ever put together so far,
What got me is how long the batteries last on these hubs, the efficiency is good the way they run and it doesn't even get warm. Seem to let out all the power when the motor is at high RPM so there is good air circulation happening. Interesting really,
-
I love the connectors. The first lesson I learned was to use good light or I Marked the connection orientation with some paint so I can easy match the plugs.
If you use the arrows or a mark to match the plugs they seem reliable.
I re-installed pie no.1 and max watts 1196 watts this hub can pull 23 amps max.
Playing with the software settings.
I noticed much power gained at take offs with the 24v setting.
And upping the max amps and cont amps gave more in take offs. But still equates to a few more max amps peak. I just set them all to full.
I think as the advert says on the web site 50 amps, These controllers should be shunt limited to 50 amps and then the software is better calibrated.
I think regen is more plausible with a low resistance shunt. The Battery I own already has a 50 amp shunt, the 40 amp solid state relay, and the "25 amp continuous" thermal breaker, now all this has to add resistance to circuit.
Besides its like there is some sort of smart soft start happening. No delay to the response on the throttle but a variable duty cycle cut in effect happening.
It seems to limit the current at low RPM which limits the heat the motor makes. Or maybe I think the controller is choked and the phases events works as a chopper for current to flow better.
At the lower settings I seemed to go just as fast, use the same watts but it was like a little baby just on take offs.
I tried out the FWD speed scale. I set it to 0 and the bike doesn't budge. Im thinking I can set the max speed here.
Hub two will go under deconstruction in the coming days, as I want to test out the 50 amp shunt theory, take some time to find out what I need to do to run this hub at higher power. Also considering removing the internal controller and boxing it with MP no:2
