can you paralel 2 or 3 of them on a new pcb made by you and find the amps you need.. all you need is paralel em i think you dont need to make em comunicate... .. even 3 of them will work cool!!! this is my thinking but the safety and stability parameters of a less experienced user isnt my concern .. its project and everything can be on table as possible solution!!!!

I am trying to build e bike, do you know much about the Hyper 9HV IS?

Geniales Video!💪🏼

classic Video

Mega nice, sitze auch gerade daran meinen Bosch selbst anzusteuern. Magst mal erzählen, welchen ESC du verwendest?

Meim Bike fuhr 85km/h.

I don't understand if your battery is only putting out 860 Watt hours then how are you able to push 3000-4000 watts of power if the max it can push is only 900 watts? I thought what you do is you take the amp hours times the voltage and that equals the max amount of wattage that your battery can push out so say you have a 4000 Watt motor you'd have to have like a 72 volt 42AH battery. 72x42=2880watts. So even then still not 4,000 watts but see what I am saying? So like I've been having a hard time trying to find a motor that can a battery that can push out 4,400 Watts because I can't find them big enough and if I do find one big enough it's like $2,000

Mein bosch ebike fäht 115 kmh Dafür sterben aber meine bremsen oft und liege bei 1,5 kw und 15 ps aber muss heufig reifen wechseln ist nervig aber macht extrem spaß das beste ist sogar die polizei jagt mich oft 😂😂 und habe mein eigenes dual battery system gebaut Vorallem ist mein motor laut und liebe den cx schön auch mal andere tuner zu sehen 👍

unfortunately although it's possible, it's just really inefficient at the moment, here's why: firstly PD only supports 100w of power max, fast for the average consumer however I personally charge at 200w, secondly, pd does not support current limiting meaning you need to add a boost converter on the output of the 20v (which isn't very efficient)

about an ebike computer: most features of such toys, such as average top speed per week 😎, are just annoying and an insult to intelligence to me. what these vehicles urgently need, however, are 1. constant monitoring of system health or failure. because every system i tried checked out in the first rain and it was a huge headaches to get the heavy bastard home, I now think mostly of multiple, entirely independent systems as well as prebuilt in checking. like some cars give you oil and water temperature (or so I believe 😌), so to quickly identify and isolate a problem. i was wondering if one could hardwire one or more of these 15 EU e bike testers permanently but I never even got one yet, so its just fantasy so far. 2. machine learning or driver training of best practices. for example, tires & batteries wear out strongest on max torque from zero, right? so it would be best to start the motor at 5 km/h, right? sth like that. just guessing. my thinking would be that, if you had a green LED in your handlebar that would be on when you are in the best long life configuration, you could learn that behavior.

could you weld the axle to the frame instead of a torque arm?

here's some extra needs for German use, that i see too rarely considered. 1. invisibility. 2 or 3 high profile accidents and the law and cops will suck all the fun out of e biking. 2. no stealing design. ideally a "don't even think about it!" design. 3. balcony sun power charging for free power. old batts are not difficult to find and rejuvenate.

awesome. exactly my interest. fuck unboxing! fuck gimcrack! fuck fancy looks! low maintenance and all weather long term reliability uber alles!

Ich hatte den 75100 (Kiste), welcher gottseidank abgeraucht ist. FOC Betrieb war mit meinem Gmac auch nach Wochen des rumprobierens nie richtig möglich, nur als standard BLDC und das nur mit rauhem Start. Der 75200 funktionierte direkt beim ersten Mal mit dem Gmac im FOC Modus. Er läuft sauber und die Endgeschwindigkeit scheint etwas höher, leider ist die Beschleunigung kacke. Wenn ich das Gas aufreisse fängt er an stark zu vibrieren. Die endlosen Einstellmöglichkeiten sind der Horror. xD

Hallo Leo, ich bin gerade mit meinem Boosted Board von der Polizei ausm Verkehr gezogen worden. Der Beamter meint, ich brauche für mein Board eine Allgemeine Betriebserlaubnis, eine Versicherung und ein Kennzeichen. Alles andere wäre illegal.. Ich will dich nur vorwarnen.. Ich hab jetzt eine Anzeige wegen Fahren ohne ABE am Hals..

Einfacher und unauffälliger ist der Weg über den Sensor 🤷🏻‍♂️

Ey Bro woher hast du das diese Bosch tool

We need a 2023 update on this! :)

Thank you !!

If you get caught by the police they will take you bike and fine you thousands of euros. I have seen it happen in Cologne.

lebst du noch?

This BMS SUCKS! Do not buy, interface is glitchy, you don't get access to parameter settings, misreads (says I have 100% charge when I'm at 20%). Customer service does not respond.

endlich mal wieder wer der etwas professioneller wirkt und auf fehler eingeht auch wenn es nur die eigenen sind echt klasse man

Well done! Do you plan to revise this to the newest 240W standard of USB C? It would be sick to use one of those 240W gan chargers for my laptop, phone and ebike!

excellent where are you in germany? i am in munich

'promosm' 💐

Leute wie du, machen mir echt Hoffnung. Viel Erfolg bei deinen Projekten :)

Hast du das Projekt weiter entwickelt? Auf die neuen Motoren?

Looks good but I think you should've done a follow up video showing how safe the bike is ; in real life scenarios . For example a tyre blowout at speed and which wheels can sustain that force and keep you in a straight line and the BMS whats the greatest amount of shock the battery can take before cutting out because if you accidently didnt see a pothole or speed bump and the battery sustains shock it will cut out to protect its systems and if you have 50km to still go goodluck getting home before dark !

Wii hhahahahah

Awesome

Wow this is a really good biker built there would you sell one how much I live up in the Yukon in Canada I don't know where you are a good way to get around especially these days cuz the price of fuel being so high

Hey Leo. I want to try and build this but it looks like the link for the bike you posted it is no longer there. I really like the build of the bike. Do you know what brand that bike is? And does it come with the second seat already attached? This would be such a fun bike to ride around town. I'm also curious how the throttle is controlled? Is that attached to the wheel motor?

0:37 motor hall sensors failed for a second?😅 the 5 volt power went out for a moment?)

I like your vedeo, my bike is hard tail aloy body with suntour pork 26 tire & all part are semano, i want to make a e-bike like yours, i'm in the Philipines...

Hi, your explanations 👍👍in the second part of the video are fully right and important, in particular the fact that we must not press too much the electrodes for welding with these "toy-devices". It 's a very good welder for building low Amps batteries, but not more, with a little stop between each welding : if not the battery will suffer quickly , work time is very short but also very hard. For this reason 2 cells in // is a good choice, much better than only one 5A cell like in cheaper welders. Lipo batteries have a short lifetime, when used or not. So I will add a female jack connector direct on the + and - of the battery to charge with my ImaxB6 with good trickle charge at the end , (much better than these little miniaturised chargers) , and also for storage charge when not used ; we don't use these toys every day. Lot of thanks for this useful video!

Я увидел ряд ошибок , одна из них очень опасна . Аккумуляторы нельзя паять паяльником , только контактной сваркой , чревато пожаром . Жаль , что я смотрю это 6 лет спустя .

I wonder if the frame will be able to take it? Probably if u take it easy on it or know how to fix it it shouldn't b an issue. 👌

Verkauf mir das als unrüstsatz 😂

what if you incorrated the batteries into the bikes frame for space saving and e-cog-neato design?

Danke

Hast Du mal nen Pellenc Akku probiert ? Der ist eigentlich für Gartengeräte konzipiert .... Liefert 50 Volt .... und ist Genial .... Der Chef von Pellenc Deutschland ist in etwa so ein Freak wie Du ....

Well, now comes the fun part, you might be able use Powerbanks as range extender.

Hab im Vesc Discord gelesen, dass der Makerbase MKESC 75200 (Klon vom Flipsky FSESC 75200) Probleme hat, den Phasenstrom zu messen, wodurch FOC nicht flüssig funktioniert. Ist das bei deinem Flipsky auch der Fall?

I'm trying to make a USB C charger for my mi scooter and i can't find the parts in my country

How can you reconfigure it to more cells in series? It didn’t work with mine

Kannst du ein Video machen, wie man den Controller verbessert? TVS-Diode, bessere Kühlung... Ich überlege selber, mir nen Flipsky 75100 (im Gehäuse) zu kaufen, aber bin mir noch nicht ganz sicher, da er nach ein paar Sekunden bereits überhitzt und reviews auch nicht sonderlich positiv ausfallen. (ruclips.net/video/HX9ivJV0Lqg/видео.html)

I thought it was 3 phase DC? Do the voltage and current reverse into negative?

Hehe, geil dich. Wieder. Zu. Sehen :D

Do block signals have any advantage over field oriented?
