Where would the timing chain be

Try this. Insert key, full throttle and gold brake at same time, turn on with key, wait 10 seconds, turn off with key. Restart should unlock it to about 60mph.

so how would you connect a keywitch that has a negative and positive

Hello, my chopper CP6 is burnt all 12V wires are burnt or burnt up. Now I have to rebuild and rewire everything, could you please send me your plans ( gif/jpg,pdf)? Would be very kind.

can work 60 degree too?

so i just bought one of these second hand,but i think the 72v wires were removed,could you tell me the position of them at the connector so i can jump the connectors? thanks!

Top mesmo se você colocasse um arquivo no Google drive com esse esquema elétrico, mas assim no vídeo já ajuda bastante.

Fwiw, the white wire "is" learning, when connected the controller learns the motors phases/timing, there many many combinations.

My friend please, could you tell me if the high brakes is working in your controller? When I send a signal to the high brake wire the controller do not regen, it just stop sending power to the motor.

Does this regen?

Hey i have a CP-4 and i'm trying to do the mod now. Do i wire the cable on all 3 shunts? Because, you're shunts are on the middle/right section. But mine are left/middle sections wired. Will it make a difference?

What motor would you recommend for this controller? Going on a razor dirt bike! Thanks

I want to bingwatch all 60 testsss lol

Then you have to pay taxes all over again if you get the license plates Is there anything in writing that says there's mandatory registration? on electricunder 4,000waats?

Techknow what up bro you still playing cs?

i have a new city coco m3/chopper. the lighting system does not work. Can you tell me where to look for the fuse or how to fix that? I am wondering if it shorted when it was first connected. HELP. I am NOT an electrician by any means. I do not have a diagram like yours. I have notified the store seller for warranty service. In the meantime, if it is a simple fix, I am all ears. My Bike gets power to the speedometer, and will go into gear to ride. Just no lights.

Good day Mr when thé wheel not turning what IS that problème ??? thanks you

What is the top speed now with the sabvoton controller?

How long did it take you start to finish?

This mod need another battery. Those batteries are not made for high current. It is much better to go for another controller that is programmable and build a now battery with higher voltage. 20s is way faster than 16s and you dont need more amps. 84v and 35 amp gives you 3000 watts and it should have a max speed of about 45-50 mph A 20s8p with 21700 cells will give you about 84v 40Ah and a range up to 80 miles

I am just curious, what country you guys live in, (not trying to be funny or rude) City-cocos are the same prices EAhora and EAhora M1Ppro does 49 MPH out of a box without any modification to speed control, cost pretty much same as city-Coco

Any idea why my lowboy won't start at all? I replace the motor that you're working on the ignition switch and the battery still will not start

Hi, I am a highschooler in the STEM academy, and my group's capstone project was to make a gasoline powered lawnmower into an electric vehicle. We bought a Vevor DC brushless motor kit to do our connection, and believe we have everything connected right, but it is not working. Is there any way we can get on a zoom call with you and show you our project and connection in hopes of fixing it?

buenas tardes, el catalogo de la controladora donde lo puedo conseguir, gracias.

thank you for your video sir, i hope you're doing well all the best!!! i'll try this soon :) Im also thinking about making a trigger near the throttle, i'll pass the shunt mod through a high amp relay, then drive the relay of 5v from the throttle.. did you ended up doing this? i read in your comments bellow that you had some issues driving and you're putting some sort of switch. i would only use the mod going on a flat straight road or while going up for a tiny boost!!! greetings from portugal, Best

Just picked one of these up with a bad head gasket, thanks for posting a good video on it! 02 sl1 140k miles coolant in oil, no start. Felpro kit was on sale and $69 shipped to my. With head bolts.

Hey buddy, how you been? just got a quick question! Is my controller red light supposed to blink?

How has it held up so far? Planning on getting this controller but i really don't trust products I find on amazon.

Very easy totest with variable power supply.

To be clear for those not following I now have bought 6 of these all said to be for 60V and none have been. Video has been taken to support this for purpose of refunds which have been successful. I am using 2 of these that I have tricked into working with 60V battery.

Fwiw, another one of these controllers just arrived. This one advertised and "labelled" as 60v-72v. It is 48 V and 72V only.

You said you are "versed".with this controller. Versed meaning "experienced or skilled in; knowledgeable about". I am just a consumer to, but have done some homework.

Programmed to have 72v battery by default.

My batter is 60v, 67.2v fully charged. 72v battery lvc 62.5v

does that controller require the hall sensors or can it operate sensorless?

You live in southern California?

Wonderful reserch your doin for e-chopper community thank you so much I soldered my shunts together instead point to point like the way you discribed should I undo that and do your recommendation?

Does the description on the paper match your controller? At two points, for example, the ground is not there, as it is on the panel. I have a different type of controller on my bike. It failed because the top speed suddenly became 25. Everything I do is 25 speed. I bought one of this type, but it has a different connection, so it has to be rewired. It's good that I found this video, but as I mentioned, there are 1-2 problems.

Dear Sir; I hope you are doing well. I know very well that you’re a high-level expert on BLDC controllers. I live in Turkey and I freshly bought a New 2020 Shansu (citycoco) CP-4 3000w 12*7.5 inch fat tire BLDC Chopper from reseller. I am in the edge of upgrading my controller and I don’t like to waste any money, but find the most accurate and compatible controller for my bike. Unfortunately no one here seems to know anything about BLDC controllers especially related to these kind of motorbikes. Therefore your consultation is very appreciated. My system is 60V&35A by default however installed an extended battery pack and with default controller, now it’s running on 17S7P (3C) 64V & 35A battery setup. By the way the original wiring is terrible. Therefore I upgraded the wire between battery and controller to 10AWG while upgrading the power slots to XT-90. By default, I can reach 700-722 RPM with no problems under many conditions, that means 65-70km/h. However, more torque & max speed is a must, when it comes to dealing with hills and highways of my city. From your youtube broadcasts and comments, 72V 80A is the final sweet spot for our rides. Therefore I’d like to have your valuable experiences, thoughts and suggestions on my following issues below: 900-1000 RPM will be the best option for me under several conditions. Cranking up the voltage to 72v seems to be the cure for this issue. However there are terminology like “flux weakening” while talking about speed of BLDC motors. I am planning to buy VOTOL EM-70S controller for more output. It has “flux weakening” and the programming interface seems to be more user-friendly than most of the others on the market. Its negative aspect is supporting only 60A nominal whereas 80A could have been better for us. If you suggest a different controller, which controller should I use in terms of i. Programmability and customizability, maybe having “self-learn” advantage ii. presence of “flux-weakening” option for extra speed, iii. durability of MOSFETs and overall setup iv. conformity to the BLDC motor of our bikes v. applicability with our default double cylinder shaped speedometer display I I’d like to thank you in advance for your valuable answers and guidance.

Hello & thanks advance for your help👍 i have an eGrace (2018) Nova Motors eRoller 72V 3000w / 45kmh. I think the controller ist faulty, because everytime i reach 35kmh (high setting) the Motor&Display goes to zero Energy for 5seconds but 12V works normal always. On Low (25kmh) theres no problems. When i buy a replace Controller (same specs) how to Set it to max 45kmh or is it out of the box? I did buy a 72V / 2000w Controller first because my seller say this fit. But all connectors are not the same 🥴 This looks like the faulty one 🤔

hEY BRO HOW DID YOU REGISTER IN cALIFORA? what did they need?was it easy? did u need m2 licence?

Have same issue as juliusdades and some others. Controller is turning on, correct voltage and wiring at hall and throttle but motor is does not move or make a sound. Have tried all 36 possible phase combinations, nothing, no output to motor at all. Can you please verify if this is same problem and also that purple wire is learn and needs to go to 12v as stated?

I just received my controller dated 2023 March, Question I have if you can help me please is as I did NOT receive wire diagram 🥺😢🤬 Appreciate you. 1. Mine has a grey single wire - I do not know what it is for? 2. Mine does not have the 2 green wires for 60-72 volts? I want to run 72volts Disappointed really, have contacted seller NO reply ☹ Cheers

Hi, i have one similar for my scooter, just wondering what goes to the charge port?

Hi fellow veteran, I purchased a 48v 750w rear hub Chinese ebike and I am attempting to add a second front hub motor with a cycle analyst and shunt to be connected to 1 battery. I have 2 of these controllers for 2 hub motor controllers and understand that both need to be wired for power, motor and hall sensor lines. Only 1 controller will need to connected through the throttle to activate the motors and I will adjust the amps through the cycle analyst. My issue is the rest of the accessories, head & tail light, directionals, brake light, speedometer/battery display, pas, brake switches are all different color wires from the original and new controllers. Also the wires are used for all the accessories are the dongle cables so i cannot see which color is coming from which switch as they are all inclosed into a junction type dongle where 4 or 5 dongle cables from the handlebars go in to the junction an 2 come out going to the controller. And as you know, the wiring diagram you showed on the video I have as well, none of the wires are marked for accessories. Can you advise me on how to proceed with this. Thanks

does it Work with LH-100 DISPLAY?

Sir update me with the. Controlled if you able to program it.

Hello sir can i talk to u??

would you tel me how to hook up a throttle to zjcp9-4860-ytc-ck2 speed controller ive looked everywhere and your the only person i can understand on here
