    Replacing Hub motor trouble.

    First I can't thank you enough advising me. Electronics is absolutely my weakest discipline. So thx. Im hooking up a new Bafang hub motor to a new controller with matching display. Trying to keep old brake,throtle etc... Both controller and display are Kunteng and recommended by AGS. My old...

    Replacing Hub motor trouble.

    I'm back from vacation (Holiday) And thanks to the guy behind me on the plane hacking up a lung I got covid. I'm so glad it didn't hit me until I got home. But this hopefully gives me time to workout the bike wiring this week. In Paris I saw how bikes are the #1 way to get around. Everyone ride...

    Replacing Hub motor trouble.

    On the motor I needed an extension cable to reach new controllers home. I found this one that matched the plug on the motor but the wire colors seem odd. One is light grey and another is bare wired. Does that seem odd to you? the motor extension cord is made by CUSMADE.

    That's good news, I hope. I received this from the bafang retailer I bought the motor from. I don't know what all this is but perhaps you do. These are their perimeters for KT controller and display.

    Replacing Hub motor trouble.

    I received the 5 way block so I wired up the big wires. I'm presuming the wire colors are matched up , no swapping around. Is that correct? I'll be back in touch in 3-4 weeks after Holiday.

    Thanks for describing. I'm understanding the process better. I'll start on it when I get back from Vacation. The last parts should be here then. Thx

    Replacing Hub motor trouble.

    This is what I was looking for. I guess I can check conductivity on the cord with a slim needle and the multimeter but its matching up the colored wires coming out of the controller. How do you have it connected up on your bike? Do you have your handlebar devices with plugs that match what the...

    Replacing Hub motor trouble.

    That's exactly what I have but if it's 1-2 ft longer it will reach the controllers new home. As is it just might work but will be tight/ limiting when connecting the wires to the controller. How will the controller wires connect to this cord? Cut and splice? any diagrams exist on correctly...

    Replacing Hub motor trouble.

    Let's talk about the 9 pin/ 5 way cable My bike is using and I hope to keep using. Ive been looking at the new controller/display and thinking how I can keep my 5 way cable. I'm thinking of clipping the lead off the old controller and using the plug with exposed wires to hook up to. Or since I...

    Replacing Hub motor trouble.

    Ok I have the new controller & display. Not all the extension cords yet to get the wires to new location. So i'm not ready to start. What is the process like getting it all wired up correctly? I'm presuming it isn't as easy as connecting like colored wires. Or is it? Also I received a email...

    Replacing Hub motor trouble.

    Cooler King would have been a great choice for what I was going for. A lower seat looks better. that frame is available here but it's delivered with a wood textured tank. Also they're sold for $1000 more than mine cost without any other improvements. My bike sold pretty cheap when paying cash...

    Replacing Hub motor trouble.

    I ordered it. Free shipping from UK. Under 8 bucks total cost. If I mailed it the other way from US it should cost $15 just for postage. I'm guessing you are in the UK?

    Replacing Hub motor trouble.

    Thanks again. I found a container to put the controller in. it's a vintage 1950's tackle box. its got nice round contours. Bigger than needed but once I remove the handle and latches it will add to the looks and fill the void like your bikes box. If I don't post for a bit Im just waiting for...

    Replacing Hub motor trouble.

    I was able to use the password but the magnet poles was not shown. I'm going to order the controller you listed with a new display that mounts the same as I have. Thanks for the lead on what to get. the controller won't fit in the same spot as the original controller but moving it will be...

    Replacing Hub motor trouble.

    Thanks, I'll try this tomorrow, I work today. The braking chain is definitely in part the alignment. Jumping teeth is a regular occurrence. That's when the chain brakes and mostly at the "quick links". When I went to a heavier duty Cargo bike chain it got a lot worse. I'm thinking the ability...

    Replacing Hub motor trouble.

    After all I've read I'm thinking the next move is to replace my controller and screen. Is buying Bafang brand like my new motor better/easier to hook up? I saw they have a controller the same size as mine is. But I don't know if it will be right unit since I would like more power. If it still...

    Replacing Hub motor trouble.

    The wheel is running very fast. I did a test slowly increasing the speed. The watts stay steady slowly/ smoothly increasing with speed until the wheel being out of balance and in the air, you can feel the shake. That's when the watts bounce too. I think the load to spin the wheel is affected by...

    Replacing Hub motor trouble.

    3- My controller is in the bike and it fits. Very tight! But if it's easier to replace it when replacing the screen I'm not opposed to replacing both. Im just concerned about wiring issues since I don't exactly understand what does what. But making the connections isn't a problem. My Controller...

    Replacing Hub motor trouble.

    1- 48V battery but Fully charged its 52V and stays steady no sag. It didn't ever sag even as it drops in volts over a long ride when I had a working motor. I does slowly lower on long battery depleting rides. 2- I have the programming cable that works with my bbshd mid drive. I could not...

    AGS & amberwolf Thank you for taking time to help me. I can't say how grateful I am. Ive put a lot of effort in trying to find a shop or supplier that has knowledge as you guys do. But only getting a polite "Not interested, good luck". A couple shops even finished the blowoff with "Want to buy...

    Replacing Hub motor trouble.

    Thanks again for your help. Id be lost without this info. One thing that is hard to see in the pic of my results. The 3 winning configurations are actually the same configuration. Each row going left to right are the same settings! All BGY in that order. The only reason all of them in the top...

    Replacing Hub motor trouble.

    I did the test but not the top SENSOR row. I followed the big arrows. Perhaps I should have gone to the top above the big arrows? Let me know. The ones that run smooth and use low watts are marked with red. Notice all the combos that seem to work are the same order B-G-Y ,this is what I started...

    Replacing Hub motor trouble.

    I'm running 2 complete separate drive systems. Inc 2 batteries that I can swap if I need to. I've broken the chain and once the cheap factory dealer. I still had the hub to get me home. The handlebars are crowded, left is mid-drive / right is hub. Basically I use the mid drive or both to take...

    Replacing Hub motor trouble.

    Here is my original motor and controller. Both are without a brand listed. Its off a Kasen bike. I posted the motor incase someone recognizes the brand. That might help with wiring schematic. All you guys are a huge help. Electrics is my weakest skillset. Kasen in Ontario, Ca are ghosting me...
