Cheers for the shout-out again mate. I'll be in touch soon - I have a project coming up which will hopefully bring you some interest 😉

Good on you for rescuing animals ,thumbs up.

thanx for your intuitive video Andy, i'm learning a lot from them. :)

The Ibera bag you are using is the one I have used for the last 2 years - trouble free I might add. Before I always had a problem with the zippers failing.

Awesome stuff as always Andy, one day I will have an E-Bike, random question though what are the mudguards that you have on this bike build and where did you buy them from, please

Well done brother, that's such a beast! I'm taking full credit though, based on mine :) remember mk1, eh? You've come a long way!.....

Is there a way to identify which version of the M620 has straight cut or helical gears? Thinking it might be best in my circumstance trying to get the helical gears since they're naturally quieter.

This is the kinda riding i do every day. Anything less than 5kw won’t do for me on an e bike. But then I commute, it’s mostly road, and I have upgraded all the components minus my 2012 Giant frame. Hard tail is best for me. Nice build. I didn’t know that motor could take that power

Hi Andy, so sorry for the delay. I'm not to sure if remember our previous chat but to cut a long story short, I've found a smaller and lighter complete spider/chainring for the ultra motor. I'll send you pics via email and the link. Only cost me £11.50 and definitely makes the bike a lot cleaner looking compared to the stock 44tooth chainring. Keep up the good work mate.

Thats an awesome motor I have one on my bike. Very quiet and powerful at its normal level of power

Another good video thx Andy. Could you please provide a link for those 21700 if at a decent price for bulk buys? Would luv one for 18650s too pls.

Nice vid Andy, lots of really good info there - your knowledge and use of best practices have really come on! I made a canvas saddle for my ebike lipos that just sits on the top bar and strapped in place. This makes it dead easy to remove for going into a shop for example. I don't care about looks at all -- the tattier the better, means it's less likely to get stolen especially in Budapest!

Shock work looks so satisfying

that’ll get your top speed up! The only thing that is worrysome is the lack of cellholders. Just make sure your cellwrappers are all pristine, only thing between positive and negative....hope they don’t rub thru! will your glue turn gooey when your cells heat up? No airspace between cells....if you have it wrapped tight with reinforced tape, monitor cell temp closely! ( esp with 3 p cells trying to do 100 amps) looking forward to the hi volt test! wear a helmut...no regen to help slow you down! cheers!

i love what u do i watch every video i wish i could get 1 of them bikes its amazing

That's a beautiful looking bicycle.. love it

Hi I have the BBSHD 1000wat Bafang. can you do this what you did? the engine is damaged? could? explain me? the frame frame where you bought? how did i developed the 4000w ?? 😊👍

Is that the Ibera bag? I had one on my old ebike as a battery bag. I ended up having to poke some zip ties through it to secure it better to my frame because I had a large open triangle. Before the zip ties it would sway really bad and it made the bike feel squirley.

Built an ebike, BaFang, how do I peddle (peddle assist mode) when the bike is freewheeling without the motor jerking each time it turns on????

Awesome ! That bike is insane.

Hello mate just wondering if you could give me some advise, i have a bbshd bafang battery and my display screen, is flashing saying battery empty with a little symbol next to it, do you no what this could be? Its brand new

HK li-po related: running two 8Ah 6s Multistars in series for the last two years. I charge them with a boost dc-dc module and no bms. Just a string of 100mA balancing boards. (3x3s) I did a lot of low voltage discharges on these. 2V/cell a few times! When I charged these exact type on an Imax B6 and used them in quads and helis, they lasted one year before at least one cell in the pack went to greener pastures. Was pulling up to 50-80A or so. On my bike, wilst pulling ~30A at most, the cells remained within 0.01V of each other, no swelling, no heating. Two years and counting. Pulling 50km+ out of these with my 2wd.

Andy, been looking at your store on cloudsto, im interested in buying a complete bike but the thing that is concerning me is this custom tax, and what the bill would be??

Figured here might be a good place to ask but does anyone know if theres a colour screen upgrade to the lcd-sw900 display, i was about to get the ktlcd8 but just found out my new controller doesn't support it, and i couldn't find a compatible 3kw sinewave for the lcd8, but i hate that I'm now stuck with a boring lcd screen after doing so many upgrades like the new custom made 14s 1.5kwh 18650 pack.

I have 5 cycles on my new 26800 battery, built by Litespeed Cycle here in the USA using a 60 amp Bluetooth BMS. 52 volt 27 ah. Does incredible so far.

I love ebikes!........build five Samsung 30q (the pinkie) battery packs just from watching utube, and though I only have had bbsHD motors, I'm hoping to get a bafang ultra with a phase runner setup like yours! Great video! Oh, and could you post a link for that BMS and those batteries👊🏽😡👍

Nice Vid !!

Andy can you revisit the wind turbine? There doesn't seem to be much coverage of then outside of John Daniels. Winter is the time when we should be more focussed on them.

Andy you just use a watt meter then.? Got my little bafang 750w 48v middrive an it's great fun. Now wanting the bbso3, you must spend a fortune

Thanks for pushing the bafang ultra, really curious to see what you will do. Still planning to use the phaserunner with this battery? Not a limitation?

living the dream, no wonder your always smiling. im so jjealous

16:34 Them lipo cables jump

Can you help me how to hookup a kelly controller to a bbs02b 750w luna cycle mid drive motor

Great video!

would it be stupid to do this to my road bike with straight bars. My stock bbshd is bumpy enough never mind go 80 kph i do about 55 kph and pretty bad.

Have a look at the 21700 moli cells good power, top work keep pushing the hobby im watching these bafangs with a keen eye very versatile. I got a bunch of dead Lipo myself I will use what I got and move to 21700 the Sony vtc4 pack 13s 10p I got chucks out 200amps no probs even in the summer.

Hi Andy, when you say "modified" motor, what have you modified specifically? Is it still stock with a higher voltage pack, or have you done anything to the motor itself? Cheers.

I love this bike :)

i recently had a problem with my malectrics spot welder after half my battery pack i burnt out 2 of the 4 bottom diodes on it. Malectrics was great about sending replacements for decent price

nice run setup for the chickens. probably had a rooster with them, as they rip out the rear feathers when matting...

Awesome, thanks for sharing. I'm range testing the Ultra with a 52v Luna Wolfpack (Samsung 30Q cells) and it cuts out power with 51.6v remaining - requiring me to disconnect/reconnect the power cable to restart. I have the controller LVC set to 38v so I'm assuming the voltage sag at 1500w is tripping the BMS LVC? Any experience with that? Any idea how to prevent the motor from cutting out like that or jumpstart it roadside to squeeze out those last few volts without disconnecting the cables?

Andy, what make is your rear mudguard ?, I have the mudhugger one, just need something else to fill the gap where your one is.

How fast do think the Bafang will cook itself at 4kw? Seen plenty of burnt out ones after modding them. I rather use a bigger motor with less chance of it being dead, I do like how quiet they are but I need more power so it's Lightning Rods kits for me.

Hi where can i get this tunner?

Are you putting that tune on the beginning of the video on Spotify mate because I listen to them while I ride my motorbike

i was going to put those in my mountain board but went for the 30qs if i had enough money id have the 30ts in a heartbeat!

Nice setup.. I have 250w motor and my rearchain won't last even 1 year.Of course i drive almost everyday and temp (-20c to 30c) Does your rearchain holds fine?

Hey Andy, is your 10 speed Shimano system still fine with that 4000w? I'm in the decision of buying Shimano 10 Speed or the expensive Sram Ex1 8 speed. Would love to hear your opinion!

Hey do you still recommend that battery spot welder after using it ?

you should clean the nickle and the top of the battery if you ever touch the surface your grease or what ever is going to be very bad for the welds.

I hope those spot welders are good, I bought one to do my 100 batteries that I have to make up.

My m620 motor temperature at times go above 50deg at 52v, so how hot will yours get at 72v?

Didn't someone recently hack into Nord vpn?

Same battery I run in my pulse x vape mod great battery cool ebike

hi Andy as always a bad ass vid.. I've been in touch with cloudsto to ask them if I can straight change out a bosch performance line 350w motor for a bafang M620..I have not had an answer do they have the same fittings.. can anyone help please

Let's see what you can do with a battery of supercapacitors. They won't last more than a moment but... that power dump will be extreme.

Nice one again, Can't wait to see how the pack performs. How did you get on with the Liito kala cells, how come you aren't using them.

Hi, could you tell me what are the mudgards your using? Many thanks 👍

What bike do you have? You never tell in vidoes. And could i do this to my 2019 Bobsch performance ex?

Surely 21700s are also Lipo???? The ones I see for sale say that

How does the battery even stay in place without rigid support?

any old bits for sale i no u got a shop but do u have a ebay

what range from a full charge

I have a Chinese bike that's had a little work done to it by me and would out run out clime top speed 85+ tweenty kill awatt motor 72 volt battery this bike well run

What bike model is that?

how much make it

Yo! Have you mingled with the idea of adding super caps for small surges of power? Perhaps only to go easy on batteries or perhaps a separate module of a few caps that would be engaged as a boost button? I have no experience on how harder would a module have to be to make it work, but it would be a nice gimmick. And is there an e-bike controller that has a solar pannel input to charge the batteries or some other special controlers that exist that let you do similar stuff? After investigating e-bikes i came to the conclusion that the biggest problem is battery+BMS coupling that would be easy to avoid by making some adjustements to a controler rendering those costly assembled batteries obsolete... Ofcourse the controler should be made with better materials and be more expensive, but it should open up the self-assembly of batteries decreasing the overal cost after 1 or 2KWh or more battery packs. It should be programable to acomodate future batteries that will come in the future with different high and low momenta... Perhaps a milion dollar idea?

hey, I got a question about legality of the overpowered ebikes, first of all, I've built an ebike as well and for sure it ain't 250w like the law says :P But could you make a video with your view on it ? Like for example explain what you think of the legal limits (like the 250w motor) and how would you react if u got pulled over by the police and questioned? what can we do to enjoy our fast and fun creations without having the cops after us ? ofc I won't be ridding 50mph in 20mph zone but like if I get pulled over because I'm doing 30 in a 30 zone what should I say ?

what kind of seat is that?

1st after digesting content 🤠

Use a big soldering iron, much more reliable joint and more metal for the higher currents.

Kirby Dragster Bikes!!

Andy, where do you buy your cells from.

nice punchy pack👍😎

Good source of 18650 cells in the UK ANDY?

Do you happen to need a Test Pilot in New Hampshire USA?

How about trying 2 wheel drive?

Where can I get those mudguards from?

Winter? we're now getting into Autumn.

Oh dear Andy, bad timing with the nordvpn sponsorship, you may wanna lookup on whats happened to them this week. A lot of youtubers have stopped promoting them until the hacking issues is resolved.

Link for batery cell

Why didn't you go with the cyclone 3000w motor if your gonna run that type of power?

Where did you get that Atlanta Braves hat? So you were a fan of the Bobby Cox Braves too, a? You've dated yourself.

Who cares about neat, that thing will be an absolute beast😊 the battery that came out of it, is there anyway to use the base plate from the old case and build up the sides to take up more space in the frame? Just a thought ☺️

Maybe round off the ends of the nickel strips?

Put the batteries in a back pack, keep the bike light. Easy charging, easy build.

What about the no-weld kit for 18650's ? Latest Vruzend 2.1 no-weld connectors get thumbs up from the experienced ebike builder at "Ebikebuilder" - video: m.kzfaq.info/get/bejne/qN-clamfuc2qeWw.html Paul G

Rescued 'Battery Hens' lol

like your chickens

Do you sell this version of the bike mate Btw love your videos

Radio ham? Me too live your channel

Andy, you realise NordVPN was recently compromised?

You mister gotta show how u manage with the chain of the motor and the pedals, bad overview

no not NORD!!!!!!!! have you not heard what's happened with them?????????? please please don't use them. all the top tubers and companies are blocking them.....

nordvpn did an oopsie

Did I spot a silver rod?

There's sticky stuff on the table. 🥴 Eeeeeegh, I don't wanna know.

I've a bigger bag lol😎
