Installing & Tuning The New KO NANO Controller on stock Sur Ron E-Bike. Stock motor and 72v battery 

I enjoyed y’all intro music

🤘😘

Hey mate If you wanted to hit us up on insta happy to help out!

@@progressive_e sounds good thank you, on instagram right?..

You changed the battery it had stock battery when you was installing it does the battery need to be changed ?

@@luke9669 Hey mate, yes we changed from stock 60V to a high power EBMX 72V. The battery doesn't need to be changed but to get the full potential out of the motor/controller a battery upgrade is required. You can definitely run the 60V battery fine I just wouldn't expect anything amazing out of it.

@@luke9669 i plan to upgrade to a CHI 60V max battery soon.

💪🤘

Yes you can

@@progressive_e Thank you very much for your answer, I think I will choose this controller. Have you tested with a 72v battery and how does it perform with that battery ?

Go x9000, the throttle feels so good, it runs vesc which is a way better firmware has been around for years so it's had heaps of development. We have got a video coming out on a floor comparison.

If your going 15KW Nano would be where it's at for price. I've just tested the EBMX X9000 on the stock motor and can say that feels night & day between better compared to the Nano but obviously it's more expensive.

@@progressive_e Thanks for the reply. I ended up ordering the Nano yesterday. Hopefully it will suffice for my needs. I guess I can always upgrade to a better controller down the road if needed. I am curious why they make controllers capable of 35kw and motors rated for the same too. Are Sur Ron riders really using beyond 20kw on their bikes?

@@JMGENTERPRISES We are 23KW everyday of the week mate. We'd run more but can't really pull any more load with our sproket sizes. We would go down in sprocket size but would loose torque for off road gearing.

@@progressive_e oh wow. 23kw. Impressive. From the videos I've seen people are all over the place at 15kw. Can't imagine more. Lol

64T is honestly the go to for any high powered stock motor. Just need to take the load off it when your asking 3 X stock power

EBMX battery is only designed for 15KW according to the warranty. I personally run 280Amps but I have completely upgraded wiring throughout the bike. Stock motor 220 amps max should be your limit for reference 👍

Hey mate it's roughly 3 X the stock power. Very noticeable difference! I think if your keeping the stock motor I'd definitely consider the nano!

All going well so far on Mark's bike! Stock motor is absolutely fine and I don't think the upgraded motor is really needed unless your pushing a fully modified bike with wide tires etc. Unless you just want it all, then get the KO motor!

@@progressive_e Thank you! I'm going to try the Factory spec KO controller with stock motor. I do run shinko 241s and lunacycle supermoto 17" wheelset where both are a tad heavier and notice the difference. That's not the modified wide tires you are referring to? Is that correct? BTW - Thank you for your time and videos. Helps us little guys a lot!

@@djdubz Hey mate we are all about helping the little guys out! I was referring to much larger wheels then stock like the ones on my bike in blue. I run 21/18 wheels with full moto tires which adds a tonne of weight compared to stock. For your current setup stock motor will be absolutely fine! Road riding does get the motor hotter because it's not on/off throttle so maybe later down the track a motor upgrade might be down the track. I personally would run the stock motor till it dies though! As long as you stay at no more than 12KW it'll last a very long time!

@@progressive_e Thank you for the detailed reply! You guys are awesome! Helps a lot and yes I'll upgrade the motor when it goes! Would running a 54t rear sprocket to help keep motor cooler?

@@djdubz Hey man if you want to look after the motor the you really need to run either a 60 or 64T when pushing higher power levels. You'll notice anyone with the stock motor and a power upgrade will usually run 64T as this takes the most load off the motor👍

Did you do your throttle calibration yet?

Also make sure your running the latest hex file

@@DragRons yes.

@@DragRons got it. I haven’t been able to get out in the wide open yet. Will do more riding in the next few days

@@DragRons I did before I ever rode the bike.

Hey mate I'd probably reflash the hex file, run through your settings again. Sounds more like a hall calibration issue but that should get picked up in the initial motor tune on the app

@@progressive_e ok thanks I will try that

Yes mate definitely. I installed a Pro controller the other day with stock battery not bypassed. Basically you just can't get much out of it because the battery is the limit👍

@@progressive_edo you have any settings for use with the stock battery no bypass?

No display, only stock surron.

Hey Mate If your keeping the stock motor Nano is all I would be looking at. If you think your probably going to upgrade the motor in a year or two I'd be looking at a higher spec controller. Need to think what will be cheaper in the long run I had the Bac4000 for ages on the Surron and loved it, also have the BAC8000 for testing too and I never thought the extra phase amps were really worth it as it was wasted on the stock motor. We are also doing some testing on the EBMX controller very soon if you looking at other options too.

Also if you can get into 72V I'd recommend that over the 60V as you'll make more power on less amps. This means less heat through the motor and the stock motor does get hot easily

@@progressive_e You are awesome!!! Thank you so much!

@@progressive_e 72V 51ah it is then. Thank you so much!

@@MuddyDrivewayProductions good move mate, the 60V is obviously fine but I think they are more of a stepping stone for people who want to stay with a stock controller for longer. 72V or higher all the way!

No, you can run a non bypassed battery

@@progressive_e how much power could i get from a bypassed battery with a nano controller? Vs a non bypassed?

@@fxxc777 personally I don't recommend a bypassed battery but it would be 5KW vs 7.5KW. some people stretch the bypassed battery to 8KW but I wouldn't recommend it, we've experienced a shortened life doing this ourselves.

@@progressive_e oh okay. Thanks! What risks are there to a bypassed battery other than no discharge protection? How does it shorten the lifespan?
