Anyone know where i can get the motor fan for the motor 😊

What at these wires for

Red/yellow/ black/blue are wires for what on ebike

Red yet blue black thin wires for what on 48/v. Controller

I cant wait until that day

Hair? You make video with good😂😂😂😂 camera

Nice

Did you ever try the Grin Statorade? I'm wanting to overvolt my dual motor e-bike and would like your opinion on the cooling claims Grin makes. It would be a lot easier than cutting in vents or cooling fans. Good channel. Keep up the good work.

Chinese bolts ungraded and inferior metal use a grade 8 bolt from bolts plus

Thanks for the info man i thought i eas screwed my hub motor wires got pinched it was called something in the motor to vibrate when I found your video I found it I just left the hall center unplugged reverse the phase wires and now it's running smooth thank God I don't have no speedometer or mile per hour but at least I can ride it to work now until I can get it fixed thanks again for the info you saved me

Great

.... It will destroy lead acid batteries....... The manufacturer doesn't care they claim it does all these different battery types.... It makes the whole bottom of your bike hot Because it's just a scam.... Who knows what it will do For your battery type

what is the name off the yellow thing

This is not the lack of quality control this is the absence of quality control 😂😂😂

thanks for the insight I am wondering if there would be any downside ig bridging with a solid wire rather than swapping resistors ?

I have 750 watt 48 volt motor and controller and I can’t find no pics that say what does what all I find is videos that say same colors get connected but here’s the kicker I got two yellow and black one orange and yellow. a red white and black. brown black gray. And I think yellow and blacks for brakes I got pics of my wires next to the controller all out and taped down to show people it I got a video from the company but the guy who taped it taken apart and put back don’t let us see what the other dude is doing this is stupid how complicated people on CZcams and company’s can’t explain what the other colors mean and every video is not my controller at all

What FET was that? I was looking for Rds in the datasheet but didn't catch that. Because that's what burns them eventually. Low Rds means less heat at high current. Also the heat dissipation (the heat it can take out quickly enough to save itself) is 140W in the datasheet which is not good for a quality FET, I think these FETs have RDs over 10 milli ohms which is mid range. You better make your own with good FETs like IRF3077. Thanks for the review. I just bought it myself.

I wish I saw this video I had to buy a new Hub motor for my bike and do not know none of this and also my throttle was damaged

This sensor number please

IWanted to see bottom of that one. Having trouble matching old one, has what I think is better current flow on raised bar material.You put it back in box without a look but I got a glimpse. But mine is got more circuits with the high flow looking top secret shit you cain't get information for. I don't what to call what I said. If you could point me in right direction it would be apprecated. I have a fiido T-1 cargo 20Ah 48v 750w looking for controller as good or better. Thanks

I have a 2 fiido cargo T-1 I think this controller needs a high capasity board. I ordered 1 but when I saw the board it looks lite not like factory.that has what looks like a strip of .020 extra heat sink material on board, like what your working on Can you point me to a soarce read or I.D. the specs? thanks if you can im dun with fiido

No Slide plates to protect your palms if you fall 👎🏼

Hello dear my own moto are red black and yellow and the throttle red black and white. But I'm questing and never get through sir 😊😅

Very nice video with full details thanks 👍 sr

Thank you very much sir your way of explaining is very good we learned a lot by watching your video you make very good video

Need a 500 watt controller

I would relocate the battery, get an electric front hub, smack on a 79cc predator engine, and jack shaft it to use 7 gears in the back. Overall, this is a sweet design, In a heartbeat, I'd order one if these were being sold right now.

im checking mine when it shows up, sometimes you look for a deal but you end up getting scammed.

Did you have your door lock wire attached with the larger red wire? Because you would need to do that.

Bro my drl circle ring went out of shape due to heat..melting issue.. Are you facing that?

Got a 3000w 72v there motor aint workin right with no weight on it all spins good when i sit on it tho it grinds and saueals

I have elecric scooter can u recommend which motor are reliable? Im using yyk50 controller

The video is fantastic. BL specializes in developing BMS for E-BIKE, which has a 50A specification that is more suitable for bicycle use.

Se me ocurria una idea . Para enfriar el motor ebike. Y es el de hacer el eje perforado por ambos lados para poder meter sonda de temperatura y algun tipo de tuberia para ingresar aire a presión al interior del motor y que eso permita una circulacion del aire . Osea meter aire frio y hacer que el aire caliente salga por otra tuberia . Se podra usar como ese tipo de bonbas de aire para acuarios . Quizas se podria engrosar el eje para permitir hacer perforaciones mas grandes en el eje y asi poder implementar la idea que dije antes. Igual se podria hacer como en los PC con el sistema de enfriador de agua . Con un sistema de recirculación hacia el interior del motor y luego sacando el agua por pequeños tubos que salgan y entren por el eje. Para luego enfriar el agua en el exterior por medio de un radiador . . En todo caso son solo ideas .

лучше показал как ветилятор ставил а не как дырки сверлил

Hi. I have an e-bike question. I bought a e-bike conversion kit from this retailer known as Pexmore. However the bike tire where the power goes is connected via ring connectors to the controller whereas the controller has bullet connectors. Is there an adapter for this?

Where does the kickstand switch sensor connect to the controller? My kickstand sensor has 3 wires but I can’t find where to connect on the controller.

What is the best controller for use in 36v and with good regenerative brake ?

Did you find the low volt cutoff?

I've just had one of these break on me today, the top Y arms snapped after 2 months. They were really good right up until that happened

Hi where can i get a fan like that if u mind asking?

Promo`SM

Dear friend, we have launched a new product that is particularly suitable for your E-BIKE;

@karma-Ebikes Top speed?

How many amps does the controller pull with a load? They claim 26a-31a but that can't be right maybe if you can unlock high speed

Good tips, changing the phase wires works for me.

My scooter goes reverse on the back wheel. The yellow green phase and yellow green halls makes it noisy but it’s working if the front is activated and not make the EEWWW noise and I did tons of trials. Can I share the front halls to the back? OrherwiE normal wiring stock like it’s wiring color matches worked but burns from back and front on the opposite way

I want to see the soldering 🥲🥲

i have the brain power 36v/48v but capacitors say 63v and inside it has 2 pinouts says 60v could i connect a 60v battery and it run fine or do i have to bridge the 60v pins or something my display says 36v 48v 60v s866 display

do the roypow bms limit the charging amps?
