Greetings from Poland !!! We love e-bikes!!

[@andykirby]

I know! I've seen some of the videos here!

[@tonymunn]

The amp clamp has a peak hold function. It would have made the comparison easier. Nice bike. I love your battery.

[@bigmac9013]

Mate I once previously commented a pretty negative comment on 1 of your vids but I’ve stumbled on you again. And I must say I take back what I said about ebikes they’re bad ass and so are your clips.

[@Y33JGL]

That bike is awsome andy , great to see you making videos again ! 👍

[@wayneuk]

FYI!!! you can also get pedal assist to function with the sab controller some code a mini Arduino although i must recommend a switch to turn it off ! as its a little twitchy shall we say lol and if you forget and slightly move them pedals your on your ass before you no it if you was not expecting it to launch !

[@paulbrookes2070]

Bro I’ve got a 1500watt Voilamart wheel and I got a 80Amp Sabvoton but I haven’t a clue what to do with the wires. I can connect the main3 motors and the power source but I don’t know what to do after that. Help.

[@mattsadler9259]

Nice build Andy,I too bought a battery from Jimmy at Insat.He's a top guy,always got time to talk batteries with you.Can highly recommend him.

[@aaronfuksa2047]

Need to get a safety feature like those kickstand power cut offs, so it doesn't take off unexpectedly. My dream is to have sine wave controller & belt drive so everybody will surprised where you came from.

[@shughy1]

awesome videos, great to see people experimenting like this

[@ionsorinporojan149]

Hi ! I love your e-bike !!!😀😀😀 I have few questions , if you don't mind : What is the range of the bike ? What is the top speed ? What power of engine ? What batery do you use ??? Thanks in advance !!! P.S. Did I mentioned that your e-bike is awsome ???😁😁😁

[@jaker1309]

I have this kit and is not real the power of the video. He has a motor of 5kw, not 11kw, the max velocity is 120kmh, but is fucking crazy and never goes at that speed.

[@episode04]

jaker1309 what do you mean “its not the real power of the video” Which bike do you have?

[@russbowerschannel449]

Its a thing of beauty! I'm gonna build one. Will have some questions later.

[@tacticooldennis]

The real problem with those switches on the brakes is when you stop on a hill you can't give it throttle without releasing brakes, so you roll backwards. At least front should be disabled.

[@srqcrna]

Nice build, I went to your website and looked at your battery and saw "Continous Discharge current : 70A" but you said yours does 150 A continous discharge, is it a different battery on your website?

[@andykirby]

Yeahbwe don't sell really high power batteries as there's a lot of room for user error 😀

[@DevinLindstrom]

I have the Sabvoton but it has been factory unlocked to 200A. It is a lot of fun. Im pushing 18kw.

[@andykirby]

+Devin Lindstrom interesting, how did you unlock it? Does it unlock the phase current also?

[@DevinLindstrom]

andy kirby I got it from a guy in China who got someone in the factory to do it. It's really fun. and yes I'm at 450 phase right now.

[@andykirby]

+Devin Lindstrom holy c**p 450 phase must be heading towards the acceleration of a sports bike! What cells are you using? LiPo's?

[@DevinLindstrom]

The bike is fast that's for sure. It tops out around 70 mph and wheelies at 30 mph. My battery is 264 LG HE4 18650 batteries set up in a 22s 12p configuration. Battery max continuous rating is 240A. When the bike is turned all the way up it should peak at 18kw.

[@cangooify]

My Sabvoton is locked but the program let me do 450phase

[@isaacfragmatic4651]

Whats the difference between cycle analyst and tft display

[@jcreedy20]

Nice name for brakes given the application! haha. Looked at getting one of those controllers. Looks to be nearly 13kw roughly at the peak! That's pretty impressive power!

[@andykirby]

+john creed yeah it's pretty insane power. I highly recommend the controller, very well built, doesn't get hot and now I've done a bit more testing the efficiency is very good, so on less crazy rides I can get more miles.

[@nigellyttleton]

You should get a calibration certificate for the clampmeter just in case it's a naff meter they will give you one for a few extra bucks

[@richardnaylor3300]

Hi Andy, I think you're right about the battery size because after I've mounted the controller underneath I'll still need space for a charger. I found rear shock springs up to 750lb to accommodate the bigger battery. Would a KP 10 amp charger fit in the space above the battery box sized battery? i'm planning on a Winchester to Brighton trip across the South Downs and find one charge point on the way. Yeah you're front mudguard is on back to front bud it doesn't really matter but it is supposed to go the other way round, if you look on some downhill bikes they have a very small flimsy mudguard at the back of the fork because that's the bit that matters, the rain & dirt comes straight up from behind the front wheel into your face so it's more important to have more of the mudguard behind the fork as opposed to in front of it.

[@wayneuk]

andy removing the brake switch i presume you havent had a runaway with the hall sensor in the throttle the brakes are the only thing that will stop u. it happen to me 3 years down the line took off on full throttle

[@andykirby]

Never had it (touch wood)😵‍💫

[@wayneuk]

@@andykirby if your round the essex area still and are up for some shits n giggles would be great meeting up

[@darrenthompson5954]

That is a nice ride. I am just fitting my kona stab out with a mid drive not as bad a😁s as yours though.

[@Luicovarrubias]

Hello everyone thanks for all your helpful information I do have a question what is the best controller for a qs205 in a mountain bike you can get for the money thanks in advance.

[@410connects]

I have a sabaton 7280 and im getting a hall error code ever since i tried to hook up a display any idea how to fix it the bike was running fine before

[@robertmotion]

Great video. Question, my battery is 48v 20ah. My controller is 48v 20ah. Manufacturer upgrade from 20ah b/c none in stock. Will this combo work? Heard it could damage battery. I use PAS too when riding. Hope you can help. Thanks. /Bklyn👑

[@richardnaylor3300]

Hi solar gaming, I have also calculated the cost to roughly just over 3K depending on the cost of the battery

[@paulbrookes2070]

Hi Andy. I’m wanting to get a Sabvoton 80Amp controller. I’ve got a 1500watt voilamart kit but it’s terrible . I just want to know do you get them from China and I can’t find a kit with a trottle. Could you help please .

Which front headlight is that? looks so much better than mine

[@ayokunanomibailey5987]

Hi love your work on the ebike plz you got idea on lead acid batteries

[@neverumindnevertell2616]

awesome bike I was going to go the same route and use the same frame and forks for my build until I found out how the cops harass people in Appleton Wisconsin so I decided to go with a Schwinn occ stingray chopper frame and go with a slower setup so they will not hassle me I have a guy lacing the 500 watt motor as we speak then going to go with a 36 volt battery and 30amp controller need to keep it around 30-35 mph at the very most actually not suppose to be more than 25mph but I will just slow down and peddle if I see them lol lol thinking about putting a radar detector on it lol lmao anyway keep up the great work these videos help me and a lot of other people so thanks

[@suparosc02]

Neverumind NeverTell I can reach 40 mph pedaling downhill and the police stopped me thinking they would have found some sort of engine to fine me, and I'm in the UK. Nope, all legs

[@chikchirik460]

I can not unlock the Sabvoton 72150 controller. I have a over voltage of 88v. But also current 150. Which I want to increase. You can tell exactly how you unlocked. I downloaded the program MQCON-current unlock.exe thanks

[@joshuahuang07]

how many cells did you use for this battery

[@BobFrostV]

Congratulations on the bike upgrade! Which battery is that? Is that 72V 26.1Ah?

[@andykirby]

+Aloysius thanks! it's a 30Ah 74V battery (18650 cells)

[@neilkime4065]

sweet build looks like vortex one

[@xpndblhero5170]

I am so jealous....... 😦

[@jerseyguy-hq8wv]

Which model sabvoton controller do yo have? BY the way I love your Ebike . I wish my knowledge of electronics and software was like yours . I have a QS 20 5H V3 3000watt hub motor and i am in the process of getting a controller I was looking at the SVMC 72150. WHAT do you think?

[@jerrypayne9617]

hi Andy, how much did you torque your swing arm connection bolt to? I built a bike like yours and can;t fin the torque info.

[@casualjoe2]

hello mate, just seen your photos on ES.. you need remove those spacers from between your new brake calipers and the frame mount, however if you do find the caliper is touching the mount then add upto 1mm of spacer, thank me later ;)

[@andykirby]

+causaljoe hey, thanks for the tip, interested to know why is that?!

[@casualjoe2]

it's so that your brakepads hit the entire braking surface of the rotor = better brakes! (yer bike looks mental mate!)

[@andykirby]

+causaljoe ahah! Thanks for that tip I'll have to give it a go. Thanks! I'm really happy with how it's turned out.

[@LunaStarFire]

Skip to 16:00 if you want to just see the bike

[@ripp3rjak934]

Is there a requirement to use this controller in any electric kit setup? Or do I need high wattage battery and a high voltage hub?

[@richardnaylor3300]

Hi Andy, loved all of your blogs Buddy ! I've researched every part to build my own E bike very similar to yours, I'm going to be using the QS205 v3 3000w Motor. I'm thinking of sending Insat International an Enduro E bike battery box and asking them to make the same battery that you had made for yourself but to the size of the box, or bigger. Please could you give me your opinion to whether or not this would work ok? ( I know nothing about electronics ) i'm also guessing that they would install a BMS on the battery for me? I will be using the same controller and CA v3. Also I am assuming I will also need the same throttle control so if possible please could you tell me where I could find this, or the spec that is required ? Thanks in advance, Richie. PS loving the drone shots! Great stuff!

[@andykirby]

Hey Richard, glad you like the videos! Cool about your potential ebike build, I would definitely do it, the Enduro Ebike is awesome platform for a high power bike. I actually sent Jimmy at Insat the measurements of the box and he came up with a design to suit, theres not a lot of room left in there once you factor in the Sabvoton controller because its quite a big controller. I wouldn't personally go any bigger battery wise even if you could because weight becomes a problem! Yes they would install a BMS however if you run as much power as I am you want a high power BMS which Jimmy said he could source but in the end we disconnected the BMS on the discharge leads of the battery and it's only used for charging and balancing. This I think is the best solution so that you dont have a situation where the BMS blows while you are out, then you would be stuck! The throttle was supplied with the Sabvoton, I dont use throttle managed by the CA, its too complicated and just adds more complexity, the throttle connected to the controller directly works perfectly with the 3 speed switch. I hope this helps!

[@richardnaylor3300]

andy kirby! Thanks buddy that's awesome information :-) I was considering mounting the controller on the undercarriage of the bike to save space for a bigger battery. I am planning on sourcing the motor CA and controller all from QS Motor company as all the connections will more likely be correct straight out of the box so I will also get them to supply the throttle as well. Any concerns on this would be appreciated, keep up the good work buddy!

[@Tacitovieira]

Is the 72v 50ah 3000w battery compatible?

[@matthewspry4217]

As Bob Hoskins once said, It's good to talk!

[@ilcooldj]

Andy, great video! please share how & from where did you source the enclosure? It feels & looks premium with all those red nuts & start key integrated. Wow

[@andykirby]

+Assaad Daoud the enclosure is actually the frame which is an Enduro Ebike or EEB, if you google that you'll find it :-)

hi Andy good to see a vid from u mate. hope u are well? that bike is really awesome u do get to play with some great products. i bet its not to long b4 the government decide there is money to b made from e-bikes with a road test and a test for riders best enjoy it while its free lol

[@andykirby]

Gary g1fsh I'm all good mate, hope you are well too. I just replied to you on twitter as well. I agree 100% about the regulations, i was considering registering this as a moped but there's so many hoops to jump through to get it approved. They need to change something, technology is way ahead of the times on this stuff.

It sounds like you have what I want. I'm hoping to build a bike I want it to go like a 125-250cc bike. I'm thinking about building a frame. I have a 200cc street and trail bike I'm thinking about using for parts. It has something like a 21"x2.125" rim and I'm thinking about using the fork & rim, I'm not really concerned about peddels. I can't peddel well anyway, (I have bad legs.) But want to get back into riding. I wouldn't mind building a quad. But only if I can ride on the street. I just found your channel. I want to learn more about the parts on your bike. And where they are from. Thanks....

Another interesting vid. I just got a pair of rapid robs delivered today half on/off rd tyres,my bike is now blinged n upgraded to the max ready for the mid drive 500w. Ive been saving but cant help look at me GT n add bits to it still got to get rid of the shimano hydro brakes n get mech ones but i love this ebike revolution. Should be ordering mid december?

[@dannyf268]

S M dont get rid of hydro brakes, there so much better than cable ones. Motor cut or not.

[@chilli-soup]

Ok cool il keep um thanks. I couldnt wait by the way i ordered today a rear wheel 250w motor 36v 13ah kit on ebay £420 pants i know but couldnt risk it as i commute on rd every day. Atleast i got the battery for when i change my mind,the hills round here are a bitch although im also gonna get a 500w back wheel to change over now n again off rd etc. What do you cycle on?

[@andykirby]

+S M oh wow your gonna have a lot of fun! And the main thing is you've started now! You won't be able to stop! Even 250W at 36v it will make a big difference to just pedal power. Also yeah keep the hydraulic brakes I've just put the hope hydraulics on mine and they give this bike a LOT more stopping power, it's increased my confidence in the bike massively... more videos coming soon!

[@chilli-soup]

Amazing!!! Motor cuts 23mph on flat, the steep hills round here no probs floated up 5-10mph could of had a beer in one hand n a kabab in the other,hills that have buggered me all my life lol Was breathing like a stroll in the park :)

[@marcus260a]

I have a question Andy, I bought a 1500watt rear hub kit. I have a 52v 20 amp battery and the controller and brake levers etc that came with the kit. The pedal assist has no settings since the kit came with no onboard controller computer. just a pedal assist sensor and the disc. Only controls are the twist throttle with the red on/off button. Is there a way to add a onboard controller so I can adjust the PAS to more than one setting? I would like to be able to work harder sometimes, cause right now the bike is just a rocket and its hard to not go too fast when I get on the local bike trails, ti will do slightly over 42 mph on full throttle(this is a china rear hub kit) can I add a controller?

[@andykirby]

Hi, there must be a controller in the kit, the controller is the silver or black box which all the wires plug into. Check to see if there’s any spare unused connectors on this box, this might allow you to just add a screen with a switch that allows you to change settings etc. Take a picture of the whole setup and email it to [e-mail]

Hi Andy I got my bike coming in 3weeks. I was just wondering what's the top speed on your bike ? Can it wheelie, dose 5000watt have good power. And is there any bad points about the bike ?:)

[@andykirby]

+Billy Price cool! Top speed is about 55mph (off road of course!) it can wheelie easily, even from 20-25mph ish, 5000W should be enough. There's not really any bad points, if I had to pick one I'd say the weight as it's quite heavy with the 30AH battery in.

[@shanegrant8441]

+andy kirby thank andy

[@mohsanali999]

hi andy have you got wire digrame how to wire in your sabvoton controller and the cyclist anylist

[@andykirby]

Hi, the Sabvoton should come with a CA plug if it’s compatible. If not you can just take the main pack voltage through some thin wires and a fuse up to the CA voltage input. Then you can use the shunt that came with the Sabvoton on the negative lead of the battery, you’ll also need to connect the reference wires so the CA can read the current. If you haven’t got the CA connector or shunt with your Sabvoton you may be better just buying the CA shunt as it’s plug and play.

thanks andy

12:34 The inner design looks pretty ugly. Sine wave controller is great. Good to see it's no longer outside under the frame which is awfull on my opinion. I could imagine China can make this sine wave controller even smaller. Europeans and americans are far behind that technology. So, better inner design, cleaner, built like a compact inner iPhone electronic design, more professional, more compact and this thing is a hit. For sure it looks great. The handling and controlling of ebikes should be as easy as ever possible.

Why anodized chainring? Must be aluminum. Get something in steel!

Really interesting stuff mate, that bike is smart! It goes like the clappers! What's the fastest you've had out of it? Or should I say dared to go? haha.

[@andykirby]

+Ringway Manchester hey mate! Cheers 😀 fastest I've seen with the old controller was 55mph but the new controller has a feature called flux weakening which is supposed to shift the power from torque to rpm to allow a greater top speed for the same power, I'm hoping for 60mph, then I'll stop lol! I really want to try it but the roads are far too wet and slippery at the moment! Getting the new brakes fitted tomorrow 😁

[@ForebUtube]

Hello Andy. Can I ask why did you exchange sabvoton for adapto ? WHat was the main reasons for this change ?

[@andykirby]

+ForebUtube hi! Adaptto allows more power (14kW) but mainly it can be programmed on the fly using a very well thought out menu system, also it has progressive regen braking, it has an integrated display which shows a lot of information like a dashboard. There's so many reasons haha! It also has range management to make sure you get to your destination without running out of power.

[@ForebUtube]

14kw is quite a lot. I think that over 7-8kw it is starting to be significantly harder to control the bike, just because is harder to keep front wheel on the ground. I was asking you, because I am hesitating if I should try sabvoton 72150 (11kw) or two times more expensive adapto.. Did you have any troubles with sabvoton regarding response time ? Did it react immediatelly, and did it follow your hand movement precisely ? I think adapto should be ok in this case. This is very important for me.

+ForebUtube hi, 14kW is a lot yes and I would now only run this amount of power with a controller that has proper torque control like the Adaptto, it's possible to set it up so that the bike is a real pussycat and will never unload all the power at once which is what the Sabvoton will do the only way to stop it is to increase the throttle delay which is still not ideal. The Adaptto is a safe way to run a lot of power and makes it useable. I think anyway!!

[@ForebUtube]

I totally agree with you that it is necessary to have proper torque control. And I dont want any throttle delay.. But why is the only way to increase the throttle delay ? Sabvoton is supposed to have proper torque control too.. I know that adapto has plenty other valuable functions, but i am just wondering if I could save money and work with sabvoton, or of its really not good idea.

[@ForebUtube]

Lets say I do not need display, charging coil, advanced BMS. Its ok for me to set it once and drive. But will I be able to do some satisfactory settings with proper torque control ?

Andy..ive been looking on your web site can you do a review on your Sabvoton MQ72260 Controller 72V 260A (550A PHASE)..iam interested in buying on but want to find out more about the product. Thank you.

[@andykirby]

Well there’s not a huge amount to say other than it is crazy and it’s best suited for motorcycles with a large hub motor like a QS273

[@funfunkydiscosdjstutz1100]

@@andykirby Ok iam currant running a 3000w hub motor with a 72v 35ah battery and a 36 MOSFET Controller with has more wires then a space ship..But like yourself just more power...

[@andykirby]

A sabvoton 80A would be a good upgrade depending on your battery cells. That motor would probably do 5000W peaks without burning.

[@funfunkydiscosdjstutz1100]

@@andykirbyMy MOSFET Controller tops out at 100 amp so it says..would be good to get the front wheel up on take off like yours and Tonys....I'am also looking at that frame set that your using for you big bike looks like there loads of room to get to stuff when needed...minds so compact i have to literary disassemble the whole frame to get anything out.

[@listeks2525]

hi Andy. do you have software to program the controller?

[@andykirby]

+listek S hi, I can't remember where I got it from now, I think I just googled "Sabvoton controller software"
