E-bike: B52 edition
You smashed it here Andy. As someone who's used a Bafang BBSHD for the past 2 years, you're really tempting me to upgrade. Even to a Hub Motor. That torque you showed is something I've wanted for ages, when I saw it was in the second highest gear I was blown away.
Did you end up just running a better controller in the end??
Im building a 750w bafang mid drive. There insane. My nephew has upgraded bac 885 450£ controller 52v he's using. Getting crazy torque. Andy bafang say 160nm. What do they pull standard. As 160 is bigger volts and upgrading controller to 52v /72
You're awesome. Smart, fun, happy and not without a cup of tea. Thanks for sharing your joy.
Don't forget your protective clothing! With speed from 4kw = 5.5hp right against a tree may hurt.
May hurt lol.
It May but it doesent have to
I believe in compassion, but I love natural selection more. Let ‘em be. His skill is his own to decide.
Awesome bike mate. I've built a 1500w ebike using a old Peugeot mountain bike, over took a car at 40mph. Gets some crazy looks
doesn't mean you need to ride that fast, i use 4kW aswell, just for high acceleration etc, but still at low speeds lol
Superb mate, very interesting indeed. Thanks for giving your time to show these video. Again thanks mate
That is amazing . Last year I finished building my 2500W fat bike with uprated controller, 72V battery and other custom parts . That thing is fooking fast
Congratulations! i am looking for build one too, how much did it cost?
@@jessebresolino8576 It's custom with carbon and titanium so around 7k . You can get far cheaper kits
having played around with a few bikes now I can appreciate this one more ! very good bike and talented creator.
Andy been following your channel for a while now and love seeing your sick mods. Thankyou for sharing !
FYI, you can add a ON/Off switch to the Phaserunner. Wiring info is in the manual. Great video!
Ah interesting, I must have missed that thanks👍
The cutoff was the same issue I was having. Your motor is drawing more current than your battery can provide so it is shutting off to keep from killing itself. Thats why when you turned the current up it shut off. For instance my motor draws 30amps max where as my old battery didnt provide 30 so if I revved too high it shut off
It's not a battery cutoff it was instantaneous phase current error on the phaserunner, they are known for this problem.
Never seen anyone push the ultra to 4k watts before 🤣🤣🤣
Beast mode, thank for sharing!
Fair play Andy. Running the ultra motor with a better controller and at 72v!! You're starting to put a lot of us bafang specialists to shame lol. Keep up the vids mate.
How often do you have to change chain and cassette?
i'm gonna build a 4kW Dirtbike with street tires soon. so this is a good comparison to learn from
Just discovered this channel. What an amazing video plus I learnt about balancing batteries properly for the first time. Truly great watch!
4000 watts divided by 72 volts is 55 amp your current limited by the batteries I do realize this was a test but for that current youll need 6 parallel to keep it safe unless cells are rated at 20 amp constant then you can go 3P. Your also current limited by the XT60 though rated at 60 amp they will heat at 30 amps heat is voltage sag along with current loss EC5 can handle 40 amp constant and stay cooler than XT60 but totally your choice on what you use. Now the wire not sure what your using but OFC pretinned is best and at that current 8AWG wire is not always convenient so back to the OFC pretinned. It can handle a bit more current than non-pretinned wire 10AWG high temp would be best that gauge wire will suffer some loss but short as possible will help and the high temp skin will keep it safe. The battery for high current like this .4mm thickness x 8mm wide nickel strip will barely get warm at 40 amps, you can still touch it with no issue.
Just thought ide toss this out there so you can get the max power and efficiency from your bike and batteries and keep it safe as well.
Steve if I buy a an ebike from cyclone ebikes 72 volt coaxial mid drive motor
Will that have enough power.
Any info would help.
@@spookmore If the battery is included with the bike then it should be built for the bike and be no problem. If the battery is DIY then the factors i posted above will need to be applied.
Look just because higher voltage increases CURRENT as well as watts when floored does not mean it is sane to needlessly run HIGHER currents the goal in increasing voltage is to lower CURRENT and INCREASE power simultaneously.
The indian dude on here believes in single cell massively parallel so balancing is intrinsic just a fat cheap thick buss bar many cells between jarred.

@@battery_solar_ev Wtf?
Chain snappingly goodness
How does one go about purchasing one of these then Andy. I believe I may be a customer
Andy can I buy one please ?
@@StewartWaddell he sells it
@@StewartWaddell look in the description, he is selling it on his shop
These e-bikes are getting fast. As a motorcyclist, my advice: Roadcraft - check it out, it will probably save your life.
Wow really enjoy the video Andy!! I am into enduro, but that looked class, and less likely to annoy anyone haha. I would love a bike like that!! Amazing.
Great diy ebike Andy!
This dude knows his stuff!
you know some shit if you own a lithium ion balance charger thingamabob
Looks like each balance wire is actually connected to two cells. So the measured voltage of one cell is actually an average of two single battery cells in parallel. One of those cells could be really high internal resistance. So it is possible to overcharge one and not completely charge the other but appear to be ok as averaged. Ideally you should measure each single cell. It will probably be fine though.
Holy smokes. Nice work dude.
You create an air channel to vent air through the battery compartment. Probably best to waterproof them first though.
Whats your call sign, saw the 2m rig...
I have the Ultra..Now I'm on the hunt to find someone like yourself to tweak it big time!
Great vid. Cheers
I really enjoyed getting half way through the video to discover that while this is happening, you're also monitoring 2m there at the workbench. 73!
😁
Gotta scan the vhf man, 73
Keep up the good work and hello from Vancouver British Columbia Canada 🇨🇦
is this good idea to have tubeless tyre for e-bike ?
"4KW! 20s1P!" ( Lol turns up amps, bike cuts out ) ... "Must be the controller!"
it's 2P
but still..
According to my calculations, that bike is pulling well over 60 amps from that battery pack to get near 4kW... That means each individual cell would be cranking 30 amps of current... *those are some really high quality cells to survive that even short-term!*
@@DigBipper188 They exist all over the place. I run 6.6C rate on lipos for 100A @ 80V... 8,000w on datalog.
Ive had this battery for two years. The cells were a few years old when I gotthem. Out the junkyard. From a Chevy. lol. They are out there. :)
@@dogdipstick what car did you find them out of. And what shape are they ?
AWSOME bike!!!
I'd live to see its climbing abilities!!!
looks scary!
to be honest before watching a video i thought to myself: this is stupid, why 4000W, but i just didn't know lol
Great video. Lots of fun. Thanks
Insane I will upgrade my bbshd see how it does. Nice.
Awesome bike.
I use 5 4s lipos with 80c discharge rate.
Mine has never cutout.
I have the CYC X1 Gen2 with a BAC855 controller
That's mental Andy!! 🤪🤪👍👍
Let's make a 144V eMTB on a 3d printed titanium frame
Went from a 1000w to a 2000w and I’m buzzing
this is Awsome looks like I’ll keep going up in watts lol 🏍
Hah! It’s a crazy addiction! You can never have too much power!
How much does it cost to build a 2000-3000w mid drive like that?
@@andykirby The only problem with having too much power is lugging enough battery to deal with it...Is it possible to have a dial on the handlebars to increase/decrease amps on the fly? As that would be an extremely handy feature..I guess pas levels act in a similar way but you know for those people that just don't want to pedal and still get some good mileage to their local trails and then turn up the heat when they get there!
Any suggestions on a good prebuilt battery cuz I have no idea what u just did. I need one already done where I can just plug into my covert kit
Now thats My kind of Prototype !! ;) Thumbs UP!
"Bonkers!" LOL.
Fantastic work mate huge admirer of you're builds will have to possibly but one very soon .
Aloha from Hawaii. I love your videos. I did similar with my bbshd but I have the sondors rockstar on the way and I’m interested in juicing the ultra it has to your specs. I generate a lot of heat maxing out the phaserunner on the bbshd and with the larger ultra I’m sure you’re getting more effective utilization of the power versus more heat. Keep posting brudda! Mahalo 🤙
Andy mate u need a exstraction fan in your soldering area. Bad bad smoke!!!!
Need you to do some work on my ebike I think 🤔 I thought 1500w was the s**t but I need this in my life 😂 keep it up if you ever did tutorials on battery building would be great I'm new to it all
look on his page dude he as a build of a 4kw battery with 18650s
whats the top speed ? how big is the front chainring ?
Bloody hell that's fast
I had the same problem with the cutoff on a 350w 36v motor I added more battery is solved the problem
Good show🏆I hope the mid drive are getting more reliable that power and noise scary.💕 my quiet brushless motor.
Haha I love the sound of powerful electric vehicles nearly as much as an engine 😅 this motor has metal gears which makes it super strong, the trade off is a bit of a whine but I like it😁
Loving the bike chap, excellent work. May I ask how you deal with brakes? You seem to be running hydraulics, for whatever reason, my hydraulic system just boiled fluid when riding aggressively. I'm not sure what power I'm producing, it's 72v - peak battery output 50A (standard 20) the bike will top out at 47mph with a rear hub motor. But I'm a little confused how you produce so much power from such little batteries too. I have 2 36v batteries 10s5p connected in series. What kind of speeds are you getting?
Love it! Nice build!
how much does it cost to make a bicycle like yours?
I have the perfect bike for the project ghost salm 4.9 /27.5
thanks
Has loads of torque looks great fun!
Hi; Thank you for your video! In your accompanying documentation, you suggest that the ebike in this video is a Kirbebike - but when I went to the link you provided - all bikes at that link use hub motors and not mid-mount motors. From what I could see in your video, your ebike is one with a mid-mount motor. Can your confirm this, please - and let me/us know which model motor you are/were using? Thank you. Josh
Very impressive take off and top speeds.
Most BMS boards cut out above 40amps so that could be why your 52v had problems cutting out
The mad professor 🤖 More power,More power 🚴🚴🚴🚴🚴🚴🚴🚴🚴🚴🚴🚴🚴🚴🚴🚴🚴
Hi. I know its old video but I have the same cut out issue and I'm convinced its the BMS. AS these 18650,s only rate @ 20amps so when you Wang open the throttle and pull 80+amps the BMS will shut down
Ok, so why not 240v? More volts are better right?
How long does the chain, rear cassette and front sprocket last ?
I reckon he would go through one of each every fortnight
Very cool, I'm wanting a mid drive now , high voltage means lower current for same power so more efficient as current causes heat, should be reasonable range with enough mah as long as you don't get too carried away with all that power!!!
Yes that’s right. What I will do when I get this dialled In is create a low power profile on the cycle analyst so I can do some distance but unleash the max power when I want to! Kind of like an insanity mode!
@@andykirby awsome, I have been looking at ebikes and mountian bikes in particular with full suspension, prices are crazy for not all that much performance ,
I'm looking at the link in your description, is the full mountian bike worth me getting or do I need to buy better parts to do a similar build to this?
I probably won't want to go quite so fast lol but it's nice to have the option...
nigelsheffield I'm about to build up a mid drive as well. His model full built has solid parts that'll get you riding and can be upgraded as they wear out, but if you've got the money, a full custom build is the way to go because you can research and pick the perfect parts for your use and even have some custom color combo
@@sageoz9886 i want a good cheap bike and this is already way over my budget lol.i do like the idea of more than 250w though in a mid drive.
nigelsheffield my opinion is that there aren't good "cheap" bikes let alone ebikes as cheap never works well or long and is a waste of money and resources when everything is done you'll wish you had saved and spent more money on a quality bike. Maybe the best thing is to raise your budget to something reasonable so you don't disappoint yourself.
ive recently built a downhill bike with bbshd i cant wait to make it 72v i have got a 60a 72v battery ,just need the controller now 👌
Hi Andy, great vid as usual and the bike is awesome. I have a 1000w voilmart kit and was wondering if I change the controller for the 1500w version would it cause any issues and would there be any benefit i.e. more speed. Thanks
Voilmart is a hub motor isn’t it? Yes you can increase the power and increase speed by using a better controller like this but your battery needs to be able to provide the power, on hub motors 52V or higher battery gives you a better top speed.
@@andykirby yes it is a hub motor, my battery is 48v 13mah at the moment but I am thinking of changing it to the bosch batteries you have used, thanks for replying.
I have a huge fat bike SURLY ICT with 5.05inch vee 2xl tires...what is Q factor of bafang ultra motor? I mean crank offset/distance when mounted to the motor... Distance should be at least 190mm...
Andy's at it again!
Nice setup!
Nice test mate, that setup looks well rapid. I wondering how your trek rear hub motor setup would perform with that controller and battery. I'm thinking maybe not as good on acceleration but maybe higher top end. Thx
That’s a good point, I’ll have to try it, especially on 72V!!
Set to li-po but the battery is li-ion, can you adjust the voltage on the charger ?
Is motor working long time ? I mean didn't it damage the wires when up Voltage so strongly?
Dewalt 54 flex volt any good for the job?
@17:41 *"How fast you wanna go that is the question"* ~~ _Andy kirby_
If I were to single speed a bafang ultra with 26" wheels what gear front sprocket (44?) and rear (16?) would be optional and would it work well?
Battery as TNT bomb
please clarify what is an e-bike? can it move autonomously? like a motorbike? cause till now i thought ebikes only work in conjuction with your legs pedaling , only assisting you. Not turning a knob and accelarate without pedaling. so what is the deal?
Hey Andy If I order this bafang ultra from your store do you think it would work on my fat tire beach cruiser? I'm not looking to beat any speed records its mostly flat here where I'm at in California. Do they make an adapter to fit different bikes?
LOL 1:07 thought that ultra was ready to move on
Sweet.... love it 👍
Where can you get the bayfang middrive 4000w setup
I hope you've got a late model ultra with metal gears at that power level.
Oh yes! Straight cut metal gears, they sound great 😁
@@andykirby this sounds dumb but what would happen if u had a hub motor on that too? Would the torque improve greatly? Using a separate battery pack for it of course
What groupset is eating all those watts? I'm using a shimano deore 11s at 2500w and it doesn't like it much.
is a bbshd (48v 1000W)overvolted to 72V?
Im ditching my QS205 and getting a Lighting Rods Big Block 8,5kW soon. But as for the Bafang Motor i would get the CYCX1 pro motor.
Yes I saw that big block, looks great, I’m wondering what it’s like on the handling because it’s mounted on the swing arm so you still have unsprung weight like you do with a hub, it must be much lighter than a hub though...., it would be better mounted off the suspension. the thing I like about the Bafang Ultra is the all metal gears and the fact that it’s a very neat installation once you find a suitable frame, other thing is you get pedals so it’s good if throttle only ebikes are not allowed in your country. I’ve been doing extensive tests at full power with 4000W and it doesn’t get above 55 degrees which is just crazy. I think it would easily handle 6KW.
@@andykirby there are 3 variants of the big block i will get the variant with the 1 stage reduction that will be mounted on the Qulbix frame. The Motor is half the weight of a QS. The Transmission is planned with a Go Kart Chain.
This sounds great. That’s gonna rip, You need to make some videos about it! Which controller will you use?
@@andykirby i want to use Sabvoton SVMC150. You know the E.R.T. Racing guy uses a ASI controller which is more optimized. But i will try to do this in this way. Building time will be around the Christmas time. BTW my nick is Compoundbike on Endless Sphere. Surely i will put a video.
Nice! It will be interesting to see how well it runs with sabvoton, I do rate the ASI stuff, it’s very good but you have to set it up right. Took me 4 weeks to get this Phaserunner nailed, that’s based on an ASI 800. Crazy amount of power for something so small.
Watched the whole video but never knew ur top speed must have misses it?:)
Very interesting motor/controller. I know the earlier Bafangs used 63volt caps in the controller - do you happen to know what these use - that would set an upper limit on the short-term power capability - that and the gears of course.
The Bafang controller has a max of 60V. I don’t think it’s just because of the caps. Here I’ve removed the Bafang controller and I’m using a Phaserunner instead.
I'd LOVE to see You on a highway with that bike !!
Nice ride. How many volts can your motor handle? Can I add two extra cells in series to my 48 volts hum motor? I already got away with an extra 1S which brings me near the 60v range but not sure what would happen if I reach 62 volts. Would my 48v controller or hub motor handle the extra power?.
Lol already doing 35-40mph unless not satisfied with torque what's the problem with 60v I think 48 is gonna satisfy me indefinitely hahahaha
The wireing cables cant keep up with load
Incredible, looks awesome mate. I have a bbshd with 52v bat... Any recommendations to get more power and performance from this setup (without changing the battery). What controller or other stuff to add?
im in the same boat. did you figure it out? what did you do? are you happy?
@@sean7193 nope have done nothing... It's quite good performance, can get over 50kmph easily. But more would be nice for sure
What does something like this cost to build?
Can you build one so I can buy one off you!? I'm sure a lot people would
Lol I KNEW there would be this comment... Too much risk involved. Build it yourself
What is the milage playing around like that? Five miles?
That MOTOR .....how lfar? I'm really impressed how much it takes, it persuades me to go the mid-drive route and go for the best solution for weight distribution.
BTW I can see you putting on a sump shield to protect the motor.
That's a fast ebike! Do you use torque arm?
Lea it's a mid-drive not hub. Bafang g510/620
I'd like to know about that radio on your bench!
Hey Andy I need your help 🙏, please can you help me find the KV constant for my 3000w Cyclone mid drive motor, and how many pole pairs does my motor have ?, I need these parameters so I can Auto tune my phaserunner.... please help and thank you 😊
Andy can you use Eggrider in conjunction with Phaserunner as you can with the ASI BAC 800
Hey andy good stuff mate . I am really looking forward to getting my 4000watt downhill mountain bike going early next year . I will be using aeg 18 volt batteries that have the tesla 21700 cells in them . I will configure it to 72 volts with a crystalyte controller .
Does the torque sensing/ pedal assist still work at 4kw?
Light weight is always nice.
