Magic Pie & Smart Pie Discussions / Throttle only works 1 time.
« Last post by Luigi_stef on May 21, 2026, 05:08:34 PM »
Hello,
I have a new golden motor rear with 48V (50V) battery.

There is a problem I don’t understand.
When I start with the thumb throttle everything is going well but when I brake or let loose the throttle and restart, the throttle does not respond anymore.
I then have to turn off the battery wait 3seconds en turn it back on and then the throttle works again until I brake or stop pushing the thumb throttle.
Then same story.
When I’m driving, I can turn on the cruise control button and keep going. Went over 2 km but as soon as I brake the throttle is not responding anymore.

Everything is working fine exept for this.
I turned up and down the Ampsettings but the problem remains.
My log list stay empty.

Can someone help me for a solutions or step guide I can follow to check.
I have 2 battery but same problem with both.
Thank you very much!

Kind regards

Now I am working with version 3 of my throttle. The first version failed as the switch is break before make. I will use a parallel circuit with two resistors, 120k to the 5V supply and 100k to GND, giving me 2,2V between the steps. I will also try diodes instead of resistors between the steps, giving me 0,7V space.

Hi there, I have integrated the information from an EZKontrol controller via canbus into a Victron Cerbo OS screen.
If you want to know how I did it? please follow us on Facebook Group: https://www.facebook.com/groups/1683643219317303/

I have also made video about this on youtube: https://youtube.com/shorts/5gaQG2N7lww?si=-NSvNOHjFdvsC8bO

Electric Boat Conversions / Re: Which potentiometer works for x20 outboard motor
« Last post by Major Clanger on March 28, 2026, 05:16:51 PM »
You are not alone.  I bought a 3kw motor kit from Miromax and received no support whatsoever when the Controller simply stopped working, all I wanted was a bit of advice.

I bought a new controller at great expense from a company in the country I live.  The company has a similar profile to Miromax re working with Universities etc.  Same problem when there was an issue, no support.

The whole area of electrification of vehicles seems to be a "Wild West" market for fly by night companies looking to make a killing.

Electric Boat Conversions / Which potentiometer works for x20 outboard motor
« Last post by Sopway on March 07, 2026, 05:02:41 PM »
hi everyone . I'm looking for help as I'm not very rich 🙂.

 I went electric with my wharram, made an outboard motor with a GM 5kw and a Kelly 140A controller, it didn't work perfectly, a little crooked in the shaft and a very noisy motor, so I found a used GM ez outboard x20.

 I sold the old motor/controller and to be kind I threw my new throttle in the deal as I made one myself.

I don't need a 3 Gear death's kontakt or a sticker that tells me which way it moves and Sorry it looks like a toy 🥴.

But to my horror I found out that it doesn't work it can't find neutral .

Well I talked to Hunter from GM but he wouldn't say anything other than it was specially made and the menu was locked, so I had to buy a new one .
and it's just 400€ at miromax😵?💫and after miromax  talked to Hunter he only helps with things you've bought from him👍. correction miromax does not help unless you pay for it, sorry for the misunderstanding.

 and to everyone who is thinking of buying an x5-10 or 20, find another option because the quality is really bad, very soft aluminum and incredibly poorly painted. and this magnet drive is not good, I started melting the whole thing when I tested it together for max 5 seconds above the water COMPLETELY MY OWN FAULT BECAUSE I DIDN'T READ THE INSTRUCTIONS.

then the motor drowns, and instead of Golden motor having some drawings etc of the motor on its website, you can get 1 instruction at a time from Hunter and when you have completed the task, you can write to Hunter again for the next task. I could see in the instruction book that water in the motor required that you pack it up and send it back to Golden motor, I don't think you want your motor to lie around longer than necessary when it is filled with salt water, it would have been destroyed before it reached China.

I was lucky enough to get an extra propeller and the thing it sits in, but now I can see that the plastic cover is cracked all the way around the bottom and has subsequently started to rust since the magnets are in an iron frame. Since Golden Motor won't sell me a potentiometer for the throttle, but only a complete throttle, I think I'll try to warn as many people as possible against buying their ez-outboard motor. And by the way, miromax told me that it was an old controller (blue) that was in it 🤔 I have paperwork that says it's from 23 so things quickly become obsolete at Golden Motor, or they've had some old crap lying around in stock that they want to get rid of.

 Regards Sven.
this forum has the same quality as ez outboard motor so bad . you can't delete posts or profile WHY CAN'T I DELETE MY PROFILE THERE ARE NO PEOPLE HERE So what's the point

Hi Don,

After studying your photo, I think removing the spokes could be risky if the nipples are seized solid onto the spokes, as it could easily result in damage when you try to loosen the nipples.
You can give them all a squirt of penetrating oil and let it stand for a while before attempting to undo them, but if they won't undo easily it might be better to clean them up and treat them in place as best as you can, instead of risking broken spokes (or rounded off nipples) by trying to remove them with excessive force.

As long as the controller cover screws come undone easily, it should be fine to remove them one at a time, clean them off and then refit using some anti seize compound. I would not use Loctite on them as it might make it more difficult to remove in the future.  Just ensure that they are nipped up correctly without over-tightening them.

If you want to blow out any dust trapped between the controller and the disc mount/cooling fan assembly this should not cause any problems as the main hub assembly is typically well sealed.

I always try to follow this well known advice: "If it ain't broke, don't fix it".

    Hello , I have been riding this bike allmost every day for years .. I have lost track of how long I have had this MP5 .. Just a couple of questions about possible maintainece . I have noticed the spokes have been corroding a little .. I keep it inside it only gets wet if I get caught in the rain .. (seldom) .. I was going to wipe them off with a scotch bright pad and use a rust converter on them (ospho) .. Just wanted to check if that's OK or maybe I shouldn't do it (ospho) .. are the spokes galvinized ?
      The other thing is the screws around the controler cover .. looks like rust on them .. hate for them to get stuck .. Would it be OK to remove them 1 at a time and clean off the rust .. Would you use a anti seize or a locktight when putting them back ? And lastly .. Would it hurt or help anything to run a air blower in the dust cover .. maybe blow out 2-3 years of dust ? Just use low ..30 pounds air pressure ??
       Thanks for any help I can get . This thing is maybe the best purchace I have ever made .. Here's a couple of pictures .. Hope they go thru ..

Hi Don,

The Grin Tech torque arms should be fine as long as everything is tightened up sufficiently.

All my converted bikes have steel dropouts and I have never used torque arms. On my High Power Magic Pie I used longer modified car wheel nuts to ensure that the threads did not strip when tightened really snug.

If both of your axle nuts were done up to ~80Nm (59 ft/lbs) before adding the additional locking nuts then the axle should not be able to twist within the dropouts.

Alan
       I'd sure like forks with nice thick steel dropouts ... How would I go about finding or ordering something like that if you don't mind ... The Lawyer Lips and thin fork legs have allways concerned me   .. Their made of steel .. the frames Aluminum .. It's all lasted this long so there's no hurry .. but if I could upgrade that part it would be great ...   Thanks Again .. And "Happy New Year" ...

  Thanks Alan ...
     
      I have the Grin one that bolts directly to the fender threaded part ... I read where you said (I think) that those don't spread out the torque as well as the ones with the long arms and hose clamps ..
      I dug this extra arm out from and older torque arm and added it to the Grin one I'm using ... Now it's attached in 2 places ..
      I also made "witness marks" so I can see if it moves easily .. It's been way over a year since I've tightened it up .. Saw the new Grin one 65 or  85 bucks I forget .. Don't think I need it that bad ..
        The Lug Nut Idea is Interesting .. Like to hear more about that ..
     Here's a Picture of what I've done .. If it goes thru ... Thanks Again for all your help ... Don ..
