It's a blessing this channel exists to give answers about these things. This guy just get straight to the point and explains everything in detail.
And i was waiting for someone to come and sit on left side of that couch lol
Lol
@G MONEY They are bots, I don't know why you are yelling at bots but ok.
Rule of thirds, baby.
@G MONEY BEEEAAAANNNNSSSS
@G MONEY BEEEAAANNNNNSSSSSS
Excellent tutorial. I had to read and study lots of detailed books about this subject to understand the differences and how they related to each other.
In less than 11 minutes, you've perfectly, clearly and concisely described and explained what I had to learn the long and hard way.
I wish this video had been around when I was learning this stuff.... well done!
I have waded through all of the amateur videos, the informed videos and the well informed videos and I have gleaned a little knowledge from them all. Some, more than others ( like testing + and - wires at both ends before frying a new £200 battery) . But now I feel I have arrived at Ebike University. Greatest Ebike channel of them all IMO. Thank you from Ireland and keep up educating the masses.
your channel has been immeasurably useful in getting into ebikes!
Thank you for your clear explanation of the power levels that’s really been a great help. Thank you so much
🌝🌚
The Ebike community seems to love the “I could climb a hill” selling point, but I’m over here in Florida getting reminded every couple videos that hills exist. Cheers.
Thanks for your clear explanation of ebike power. I’ve been researching the subject for a couple of weeks, and yours is the best, most straight forward explanation yet. Again, thanks. Please keep up the good work.
Looking forward to your DIY motorcycle conversion book and video series!
Well, for those like me, haha, I was unable after welding batteries purchasing BMS's to be able to understand exactly how that final S series was counted. It finally hit me after going back to basics, watching these very easy to follow builds. That, the final S count that I was always missing was: the very first battery that has both the positive and negative going to it, even though it wasn't exactly making an S series connection, was the very last counted Series battery. Maybe very easy for everyone else, but had been banging my head around that for months. So, Thank you so very much for helping me stop feeling so stupid and knowing for sure I knew how to correctly look for and buy the correct BMS for the battery builds I was doing.
That's not correct. In a series connected set, positive is on one end, negative is on the other. the path of electricity has to travel through each battery one after another.
Can a maximum current ina. Battery be 32a&72v? Is that correct???
Great video... Yes, torque ratio to watts is the most important measure. It's how the bike will perform off the line and up hills. Basically how the bike will 'feel' to the rider. - Sluggish vs muscle.
last but not least wheel diameter (in case of hub motors which put less strain/wear on the mechanical drive train) plays into how efficiently those Newton meters actually propell the vehicle forward. The smaller the wheel the sooner rotation and efficient rpm can be achieved.
I have a rickshaw which often amounts to a total system weight of 600+kg, but with a geared hub motor in my 16 inch front wheel I'm getting the most when starting the race at the green light at Octoberfest outrunning my colleagues with 200kg less who are running the same 250W nominal system on slimmer tires but with 26 inch diameter.
(it might also have to do with me being the GOAT in rickshaw racing but don't tell them that ; )
One of your best videos! Very well explained, I wish I knew this before I bought my first ebike a few years ago.
First class and full marks - easily one of the best explanatories I've ever seen. Thank you very much and happy travels (remember: "No helmet? NO WAY!").
this channel is quickly becoming one of my favorite youtube channels, this video is extremely informative, i dont yet have an ebike but my father and i are both interested in getting an ebike so we have been trying to soak up as much info as we can before purchasing our first ebikes, thanks for the all the informative videos you put out there :)
Build one. It's cheaper and you get to know how they work
@@marcus.H that would be nice, however that's not currently financially viable for us
@@acehighdan sorry to hear that.
Hopefully parts will become cheaper in coming months.
One price of advice I would give for those just starting out is that if you pick up a Liitokala hoverboard battery from AliExpress for $25 you have got a sufficient battery to get you started with a 36v kit.
If you could do a shift extra each week at work, you may be able to save up the $150 needed for the motor and controller in a short time
Or wash cars or Windows for money. Or now lawns
This would be a great tutorial lesson put into a full series. Explains things in an everyday way of understanding.
Wish this video was there 3 months ago when I was struggling to understand these things, thank you! :)
This is my first time to one of your videos. I’m subscribed!! I understood everything while you talked, but need to listen a couple more times to really understand.
I’m shopping for my first ebike. It isn’t easy. But, you have helped a lot!! Thank you! I’m going back to listen to your other videos! I needed a white board with your numbers on it. Visual learner, here. Good job!
You make such truly helpful videos! Thank you.
Very enjoyable and clear explanations of a topic that is usually portrayed as confusing and impenetrable.
Micah-this was helpful regarding power, with good examples. I would be interested in hearing a similar approach to torque ratings. Thanks!
hey Micah, Great videos, i used your lesson to make my first and 2nd ebike. thankyou and keep up the good work
Really outstanding and thorough review of motors. Thanks Micah!
I have been watching your videos for a long time and thanks for your information I learned a lot throughout time!!! I became scooter technician and a lot of information came of watching your videos!!! Thank you my brother as always! Great content!!!
I love you dude you've taught me so much and getting all this info makes me knowledgeable enough to build an ebike
Very good explanation of "power". Keeping it simple using VA can help those not familiar with end to end input to output and the various losses along the way. Something to consider is the fully charged battery versus the nearly discharged battery. Power is greatest when the battery is fully charged and is minimal with a mostly discharged battery.
Thank you for taking the time to make that informative video 👍
The first time I watched it I didn't understand, I had many doubts about... . now it became clear as water. thanks a million
This video did clear a lot of questions that I had, Thank you.
Great video. I always look forward to your explanations.
Thank you - very helpful. I look forward to continue to learn from your your youtube posts.
Always good infoand always anxious for more, thank you.
Thanks for explaining some of these terms as they apply to the ebike market place. I just recieved my T-1 replacement and didn't understand why the new motor was labeled 250w. Now I do.
THIS WAS ALL THE INFO I WAS LOOKING FOR! thank you so much for this video!! you are amazing
Very nice video and didn't know, how much i wished for this video until i saw it!
Hey nice job that clears up my confusion. Appreciate it.
Thanks to all the information you bring to use, I'm building my first ebike
A really useful tutorial/vlog. I had wondered why there is so many different claimed power outputs
I love your videos! I have learned so much!
1:27 Yep, a big 10 ton trolleybus has an electric motor rated at 100kW. That low! But that is the continuous power. And trust me, during acceleration from standstill, the motor drives much more current than 175A (runs at 600V). That is the reason why there are components limiting maximum current, as the motor would happily take all it can get. And yet, differentials and axle reductions wear out sooner on trolleybuses than on buses. And if the regulator malfunctions, a trolleybus can easily do a burn-out on a dry paved street. Of course, do it three dimes and you can replace the whole axle, if the CV joints on the shaft between the motor and differential do not break sooner. Or you blow the circuit breaker in the trolleybus (should break around 380A, but that is only theoretical) or you trip the breaker in the electrical substation feeding the section where you draw your power from. If you had no protection circuits and a very powerful source, applying 600V directly into the motor would most likely result in lightnings flying out of it and ripping it from the frame of the trolleybus, destroying everything between it and the wheels of the driven axle(s).
I know most are watching this for the knowledge of the ratings, but this has actually taught me a lot about battery building. A concept I never understood was the max wattage rating, and now I understand, its just the max current the battery will put out multiplied by voltage.
Clear and concise explanation. I have learned a lot about ebikes from your videos.
Thank You!☮
Brilliant video so enlightening,keep your excellent videos coming thanks.
You talked about this several years ago (I think too, it’s also in your book) good to hear again. I think you put it better here. It’s not as text book more layman’s terms I guess. Same but more relaxed and I think easier to understand. Good to hear again very important. And yes we do benefit if we know how to take advantage. That we can (w/aftermarket controllers) put together a bike that we love to take for a ride!
You are best profesor i ever had.
It is easy to explain something when you know it.
I enjoy just to listen you.
Thank you very much and keep going
Thanks Peter for clarifying electrical power ratings and some extra tips (torque).
My head hurts
The ultimate ebike guide please,if I do not win a book this time I will buy it. Great video
Thanks, here in the UK, as you say we have 250w continuous, I am very happy for the manufacturers to allow us to overamp their motors for more power, they know we will not burn them out at say 750 watts for a reasonable time.
I may be wrong, but I think the Bafang 250, and 350 are the same motor but different controllers to allow more power.
It is a way of giving us a good product and stay within regs, a point you made well.
only danger with overamping would be being involved in an accident having your bike looked at by a sworn expert making you liable for operating an illegal motor vehicle.
The bike squads in Germany are no fools and are regularly making examples of obviously overpowered "250W"ebikes (which could be legal if they had a moped plate and all the other items required for fast ebikes)
@@velotillthis is why the laws are a bit dumb. What should really happen is there should be a law on use of peak power to allow fast starts and uphill runs tied to the amount of torque provided by the rider. Fast starts for 10 seconds up to 10 kmph on flats (until you pedal past it) and during cornering to get you out of trouble and when hitting an incline allowing the peak power to stay on for as long as you provide enough torque to keep up to the maximum speed llmit of 25 kmph.
simple and effective as usual! Thanks for the video
Wanted to know this for years! Thank you
Great explanation of what can be a tricky subject.
Awesome video, I watch all your content !!
Great video. Love to see you do a how-to upgrade your e-scooter video. Thanks
This is my random comment, The Ultimate Do It Yourself Ebike Guide.
Thank you for this video, it explained a few things I was trying to figure out. 500W 32kmh/20mph limit where I live.
Thank you for this valuable information. You explain the technical aspects in great laymen's terms.
Thank you this clear explanation! Usually, when people ask for the power of a bike (or car), they want the max (peak) power, like with petrol engines.
from many months i wanted some one to explain about this topic thank you for the content.
Finally a honest and clear picture for a newbie!
Very useful information,thanks for clearing that out Mikah
Vary informative video I am an ebike and battery geek and I love learning new things about anything to with eather of them. Thank you
As always, amazing info, simply stated. Appreciate it!
You explain this so easy and to the point. Thank you 😄
Excellent tutorial. Thank you I have learned alot from it.
Very interesting information as always. I’m so glad you mentioned Newton meters as that’s how I judge the power of a motor. Seems like your bicycle clock like mine needs new batteries.
Love the explanation!!! Keep it up !!! Ebike 4 Life!!!
Just great! Very informative. You really have a great talent and know haw to share knowledge in a clear, understoodable manner! Greets form Poland!
Very helpful - thanks for laying this out!
Thanks so much for the information. This has been extremely helpful in purchasing 3 e-bikes for my family and I.
This is the best described video of ebike motors anywhere. Thank you.
Nice video! This helps me to understand the about the watts and controllers. Thanks
Ordered a couple books, hope to be seeing more of you
I want one! Thank you for clearing that up.
Thanks, Micah! Another great video!
A question I have is, What choices are there to charge a ebike battery 24, 36, 48, 72 volts?
Awesome! I've been so confused on those ratings, thanks for the help!
Jose Munoz I’m still confused. Maybe if he got off that couch.
Super clear and useful. Nicely done!
More great info in my quest to understand & build batteries. Thanks
Thank you so much for this detailed info.
Thank you for this information. Always helpful. First time i took notes on a youtube video lol.
With motors I just look at the newton meters of torque and the Rpm’s after checking the volts and amps. Thanks for the video
Awesome video and great info. Thanks.
Thank u for clearing up the confusion that proceeds us I would like to get the ebike book
A very clear explanation. Thanks Micah. Be Well, J.Q.
Wow! So clearly and thoroughly explained! Thanks!
Very helpful information. Thanks!
thanks for the information. really clear, please can you continue the electric motorcycle proyect ? the part 5.
Thanks Micah, this is very useful information.
Hi I have just placed an order with amazon for your book on lithium battery building , I have had really good / the best information on e bikes from your TH-cam post thank once again
Great explanation of E Bike power. I made some useful notes esp power calc. Thanks
Very informative. Thank you for explaining it.
Great video, very informative. Thanks from UK. 🇬🇧
Thanks for the video and the information. God bless.
Great explanation - makes it super simple.
Excellent information, i was struggling with that
Great video! Really brings some clarity to this consfusing subject. One question, since the battery voltage fluctuates, (for example my 60V battery is around 69,7V when fully charged), shouldn't the peak power be calculated using the maximum voltage times the maximum amp draw? Thank you!
I guess he doesn't answer questions:/
A great overview of e-bike power ratings, thanks! 🙏🏻
Thank you 🙏 as always very easy to understand.
Another good explanation, thanks.
Thank you! I'm getting a DUAL motor, DUAL battery E-Cell Monarch 1500 and now I know how to find the real power of each motor.
Always great!!!
Thanks for the information, great video.
Really grateful for your clear explanations.
