Hi guys,
I have a trike with a 36V 700W Brushless hub motor. I recently blew out my controller with a LiFePO4 36V 20AH battery; it had been driven with SLA 36V 12AH batteries. I lost power, and a loud hum came from the motor.
I would like to know if I can connect to a GM Cruise controller, and what changes I would have to make in order to run at 36V, and which controller would be best.
Any help will be appreciated.

Hi and(https://i.imgur.com/evDSMvT.png)to the forum.
Assuming the motor is still OK, the BAC281P controller should be ideal, but you will probably need to change the connectors on your existing wiring to fit it.

For more information take a look at the wiring diagram (http://goldenmotor.com/e-Bike-DIY/Cruise%20Controller%20Wiring%20Diagram.pdf) and the user guide (http://goldenmotor.com/e-Bike-DIY/Cruise%20Controller%20User%20Guide.pdf).

Hi, Thanks for the info.
From what I have read in this forum there seems to be some problems with the USB connection being recognized or a problem with the driver. Has this problem been resolved? What point is there in buying a programmable controller if you can’t program it?
Do you have a pic or a link to the types of connectors required?
-
Perhaps a better question on the connectors might be; does GM include/supply the connectors for the controller with their mates?
I can rig some sort of connections but to have the proper connectors to start with would make the task much easier.
-
Yes, I received the correct wiring harness with the magic
controller when I upgraded from the earlier version.
It does not (or at least mine did not) come with the
connectors for the horn and aux stuff on
the right hand side above the hall sensor plug.

Hi, I sincerely wanted to purchase the BAC281P, and PI-0200E, but to pay $15.00 for shipping a set of wires is ridiculous. I think GM is milking this cow a bit too much. The wires could be shipped in an envelope along with the controller at no extra cost or maybe a buck or two.
I guess I’ll look elsewhere for a controller where the manufacturer doesn’t try to bilk me.
If anyone at GM has something to say that disputes this I am open for discussion.
Regards,

I agree. But I wouldn't scratch my ass for $15 little only work sending out a wire for $5`7 dollars a pop, what a life!
The price is interned for people who want to buy a wire only.
GM also do not charge full price of delivery and absorb some of this expense themselves. At the end of the day you get cheap motor and if you want to play it costs you a little extra.
I think some of these suggestions would be better provided to the sales rep. A good email and you can find some extras chucked in the box minus the cost shipping.
Packing, checking and double checking would be arduous. The software for that cable costs money to make too. PC software often is expected for free.
Maybe consider the software development that surrounds this wire when you consider the full price of the wire.
They should price things accordingly though. Maybe GM are trying to make something that looks cheap ( a small wire) cost effective.
-
If they were to sell the software separate and charge $10 for the cable delivered, people would share the software and the whole development of the USB cable software interface would only be supported by the profits from the sales of a $5 cable - delivery.
I would support such price hikes while development is highly active.
-
Whatever their logic is it makes little sense to me. They give away the software, and then try to abuse their customers with a high price when one buys the controller, and wire set to operate their device.
If they want to sell their software then do so, but charge people a decent price on shipping parts.
Don’t approach me with free software, and make some insane price on the material to use it. They are making enough money on the controller to include the wire set at a fair price.
If they would rather lose the sale on the controller, for the price of shipping the wires that’s their problem. I wished to buy the package.

Ok ok ok I get it, but no one would buy the software and the cable's worth a dime. That makes a 20c to make cable worth, what, $48, no matter how you price it, it looks expensive.

This is such a huge misconception about GM and the profits on individual items. The average customer sees all companies as an entity that’s making a huge profit and ripping them off to do it. For one thing the profits on all the GM products are allot less then the average person would imagine. Have you compared GM’s prices with the competitor’s equivalent items? As a dealer, after paying all the expenses taxes duties etc, If a profit is still actually made on an individual item, it is very slight. The controller you are referring to the profit is smaller then most other items. Somewhere around 10 dollars I believe. Now if I was to sell this item to someone in Canada I have to also pay the 13 percent tax on top of the sale price or I would have to charge 13 percent more then GM China sells it for. Why would anyone then by from me? So think about that, 10 dollars profit minus 8.45 (13 percent of 65 dollars) leaving a whooping profit of $1.45. The item then has to be picked from stock, then packaged (packaging cost money), then labelled (ink and paper) and in my case driven to the post office (time and fuel). So what is my profit at now? This is why I charge the same shipping as GM china as well, I have to have the items shipped to me then to the customer in many cases it actually costs more. Of course with sea shipping, the shipment cost is lower, but a huge investment is laid out and months go by waiting for stock then you have to pay duties taxes handing fees customs charges etc. You have to have space to store the product as well. Also there are website costs, accounting expenses internet access. Equipment, my own time, etc, Then if you make a profit you have to pay tax on that! The list is long and I’m sure that I’m forgetting many things as I'm writing this on the fly.
The only way you ever make any profit is when a customer buys multiple item, then 5 dollars on this item 10 dollars on that all adds up.
So when you say “they are making enough profit on the controller” I think you are mistaken.
Now of course this is the view of a Dealer, not the manufacturer. However I would think they have expenses to. Certainly a lot more then I do. I wonder what the Research and development was to develop the controller and the USB link? So on a single item like a controller I would think the profit is next to nothing, some profit if you buy a second item, If you buy a whole kit then its worth being in business.
Anyway I hope not to offend you but simply explain why shipping on some items may seem unreasonable. I think it’s because they are actually trying to make a profit. I charge the same cost and shipping as GM china does as I’m also trying to make a profit. I have been in several businesses in my time and the profit margin in this one is less then most. But this one has huge potential and is of personal interest to me so I stick with it. I think most GM dealers think they are going to make a lot of money at the beginning, But after time the ones that stick with it do so because they believe in and enjoy the product.
Another perfect example would be something most of us use everyday ‘Microsoft Windows” xp, vista, seven whatever. I wonder what it actually costs to burn a dvd with windows seven on it. Would it be as much as a dollar? I doubt it. But what is the current cost to buy it? Do you think Microsoft could survive it they sold it for a dollar? 10 dollars? 50 dollars? 100 dollars? I think it probably needs to sell in the 200 dollar range for them to survive and they need to sell millions.
Enjoy the Ride!

P.S. if you do look elsewhere and find another controller that is programmable by PC, Please do come back here and let us know about it, I’m sure we will all be interested.

Said well Gary!!
One detail:
Now if I was to sell this item to someone in Canada I have t tax on top of the sale price or I would have to charge 13 percent...
Here in Brazil we have 60% of taxes (and this covers the product+shipment+other import fees), so most of my base prices are higher than the sugested sales proces from GM, and then we have more taxes in the profit.
We use to say that we have 1• world taxes and 3• public services lol
Just an off topic comment

Said well Gary!!
Thanks for that, I had to re-edit that one a few times. Everytime I read it I sound angry. Im not. I'm just trying to explain the realities of the business we are in. I hope the "oldbiker" does not take offence ;D
60 percent taxes WOW!

You don't even want to know my opinion on this matter.
(just a little hint... I purchased from a US distributor and quickly following my purchase, they apparently don't sell anymore from their website, nor respond to any emails regarding help needed.)
I think dealing with the Manu. directly, helps with returns and issues and questions.
That's just my .02

Unfortunately, It would seem every dealer has its own level of support offered. I think you would find anyone that has dealt with me or my website has had all of their email answered in a prompt and courteous manor and any warranty issues have had the highest level of support and follow up.

Canada = NOT US distributor ;)
However charging the same as GM China does in terms of shipping is not the best idea, because when shipped from China at their prices, it's only taken a day or too longer, so since I'm not a big "NEED IT NOW" kinda guy.
I would rather get it directly from the manufacturer.
As an example... I'm still waiting for a replacement controller, from one of the Distributors (NOT Gary) and it's been 6 business days and according to the shipping company, it's expected to arrive by Wed. that's 9 Business days. (When I purchased my hub motor from GM China, I got it in 7 Business days.

Believe me I would like to sell things cheaper. It would certainly help sales. But there are some realities that come into play. GM China makes the items, not me. So obviously they have a larger profit margin as they do not sell them to me at their cost. Everything has to be shipped to me and then to my customers. How would shipping something twice be cheaper then shipping it once. If I am out of stock on an item, I have it drop shipped from the factory to the customer. The shipping they charge me is exactly what they charge the customers, there is no shipping discount for me on a drop ship and on several items they actually charge me more for shipping as they subsidize the shipping for customers but not for me.

The last 2 controllers I sold were delivered within only a few hours of the time of purchase. I deliver many items the same day as purchased, many more are received the next day and some take as long as 5 days across Canada. International items obviously take a little longer as some are drop ship and some come direct from me. It depends on what country it is going to or if I have stock. Anything in stock that is ordered is shipped the same day, unless the post office is closed (8pm) then it goes the next day. Anything that will be drop shipped is ordered the same day and then it is shipped by the factory as soon as possible, I like to think as a dealer I have some priority, The lag at the factory can be anywhere from shipping the same day to sometimes having to wait for weeks for stock to be produced. Receiving your item in seven days from China is amazing. I would like to see the tracking number on that one. Most items take 2-3 weeks and some take even longer. I have just gone through a huge shipping lag from GM China as it is the busiest time of year and with new products in production others have fallen out of stock and some things have taken 24 days before leaving the factory. Most delayed Items have now been shipped and they are catching up but right now GM China is the busiest place on earth!
I am very sorry that the dealer you purchased from is not giving you the respect you deserve, I put a lot of effort into customer satisfaction and this does bother me. It doesn’t matter to me who you purchase from, As long as you receive your items and are happy with them we all win! Happy customers are good for all of us.

Well… I finally broke down and purchased a GM kit. I do hope it functions properly.
I’ve been riding this trike for a while now, and it got comfortable.
Over the years, trying to be able to get around has been very expensive or inconvenient.
So I gave up cars due to health issues but I still need to get around.
Then comes electric bikes.
I will do anything I can do with electricity as long as it is interesting, and fun. With electricity it is always interesting. Fortunately the rest of the world did not have to suffer due to my lack of formal electronics training. But I will play on.
At this time EV has my interests.
I just don’t know enough to fix some of my problems with electric hub motors.
For some of you young guys I do hope you can manage to make some money in this ‘ordeal’.
Make America produce the best electrical road products available.
