That is sweet, the wrap has tidied it up nicely..... Im loving this ebike weather. Ive just completed my first conversion, its so addictive. I think my next route is to get a good frame and piece it together over winter. Thanks for the great tips.....
Just a heads up with soldering rather than crimping connectors ... I was always told that it was a bad idea as with large loads the heat can actually melt the solder (especially on a high amp DC load like this!) and so crimping with a ratchet tool is actually more secure
This is impossible when the proper wire-gauges are implemented: The reason a wire heats up, is due to it's resistance. Solder has a melting point of at least 180 degrees Celsius, which is generally higher than a wires insulation can handle. A wire can heat up to those temperatures when it's gauge is way too small, or when there's a continuous short in a high energy circuit. If that would happen, the whole system would short out due to the insulation melting, (eg the wire would fail) before the solder has a change to melt. Though it's unlikely a wire would fail, as quality e-bikes are usually equipped with a fuse.
The Sabvoton is a sine wave Controller. presumably your old controller was PCM.. if you think about the way a motor is wound, and the way it works, when one winding of the rotor is approaching one winding of the stator, your old controller was giving it "full power" for a short burst.. but because the winding was still some distance away, a portion of that pulse was being wasted. .. with a sine wave controller, the pulse starts at zero, and winds up quickly, as the winding approaches the stator, so you're always using "just enough" power for the exact phase of the motor. an advantage of this is that you can achieve a higher maximum power delivery, because each winding is only at that maximum power level for a really really short period of time, AND the motor is hardly ever out of phase (which is one of the reasons the motor got hot) . either way, you may want to change the power settings to an even 11% spread between each of the 9 levels..
I reckon this guys videos are among the best content on RUclips consistently brilliant and informative videos on his brilliant build its by far the best ebike videos on here
Brilliant!! Yourself and Tony's level of knowledge on this subject is mind blowing, and rather scary to us everyday ebikers! I've learned so much in this last year but feel further behind now than ever with you & Tony leading the way. Again Andy, Brilliant stuff!! Feeling deflated lol
Andy Take a look at Wago lever connectors instead of chock blocks. Very nice and good connection. Easy to remove later. Very quick. Have fun in this weather out there!!
You get grips on with hair spray. They will slide on after spraying on bar and inside grip and then act as glue to stay on. What we used in motorbike racing
What a fantastic controller looks great and works so well and keeps cool I know you used to have heat problems with early controller but this one is a must have. Dashing around those county lanes and tracks who could resist that in this weather. That wrap looks super cool you put on the Ebike. Great video keep up the advice very informative.
If I am an idiot and bought this elsewhere without the LCD screen - is there any way of purchasing the screen and getting it to work after the fact? Or, is special programming required? Thank you!
Unfortunately you can’t add the screen without a lot of hassle. There’s a connector for the display and one on the controller which accesses the controllers MCU to give you all the readouts like voltage, power, assist levels etc. Other thing you could do is get a cycle analyst which is a really good display (but not colour)
I think I might just go for it, and create some USB to something else connector I unplug from it for when I want to program it vs. use the display. Thank you so much!
Hi Andy I know it’s an old video but wondering if you had any suggestions for me as my sabvoton tft display seams to have died on me today have checked the controller using an old sw900 display that I got with my csc motor kit and all else seams to be fine
Hey Andy, thank you for putting these videos together. I am pretty new to ebikes so your videos have helped. What DC circuit breaker are you using? I have the Sabvoton 72150 but a 72v 20AH 50A battery (I took all the defaults after the hall test).. My circuit breaker (12V-110V DC Miniature Circuit Breaker, 60 Amp 1 Pole Battery Breaker Protector) seems to be tripping if I gun it in the 3rd assist. Any suggestions would be great?
Andy can you help had this controller before dosent work anymore looking for the same power but in a smaller version can I get one as the model is 3 years old now
Love your videos. I've just made my 1st ebike. Nothing special, just a cheap kit for my mountain bike. 1000watt motor in the rear wheel with two 6s packs. Goes very well. I'd like a bit more range but speed is pretty good. Please wear gloves buddy, even just lightweight thin things will save your hands.
7:11 nothing wrong with terminal blocks man, they’re used in marine an automotive anyways 👍 However people just get all Dickey and think you have to have connectors, they’re the hallmark of a seriously decent builder and someone that intends for their system to last. You however tend to change components every now and then, so terminal blocks is actually a smarter choice long term.
Ps just wire your key switch in series with the displays power switch feed :) This will prevent from being able to turned on before the key is turned on :)
@@JamiePineappleWyatt heyyy instead of a key switch i was hoping to use a $20 motorcycle alarm/immobilizer with this exact controller, how would i go about wiring this alarm/motor immobilizer the way you described with the key switch ? i only reply to your message cause it is one of the most recent ones on this video and i need advice lmao .
What to do if the motor runs in reverse ? I got the same controller and it doesn't have a reverse wire. It passed the hall test it just goes backwards, its orientated correctly with the brake disc on the left side, I don't think I mixed up the wire colors... tried swapping 2 phase wires it didn't help, it just wont go like that.
Do you have much problem riding the bike in the heat? I live in a place with similar temperatures and I am putting plans together for a 15,000 W hub motor and a 200 amp. Sabvoton controller. Just so I’m clear I’m talking about problems with the bike and that the fact that it’s just hot out there. I actually like to ride in 100 to 110°F temperatures it makes my arthritis stop hurting lol
Presumably the battery pack is a lot heavier than the controller? Any reason you haven't tried to put the controller under the top surface of the box and the battery in the base of the box where you currently have the controller... Better weight distribution??
How's it going.. I have a 72/150A controller with the TFT750 display running a 5000W Risun motor.. When I turn the throttle, it goes one speed until half throttle then goes a higher speed, and stays that speed from mid to full throttle.. How do I set it up so the speed increases gradually as I twist the throttle a bit at a time? I am using the android app on my phone to access the parameters menu.. Thanks..
I managed to hack in both a keyswitch and a remote immobilizer on mine by tapping into the +BATT line that goes into the display and putting both the key switch and a remote relay in series with each other. It's not a hard mod to do if you have the newer versions of the SMVC7240 up to 72150 with the LCD kits. Just make a connector that plugs into the passthrough connector that comes off the +BATT line
Hi mate looking to buy the 60amp kit off your website, will this be ok for a 1000w hub bafang motor? It has the small 9 pin motor conecter. currently has 48v battery im going to upgrade to a 52volt. Has a silly 22amp controller right now, with no shunt to perform shunt mod
Love the videos Andy I’m building a very similar bike 5000w motor and 52v 30ah battery but cannot get the controller to put out more than 37mph any chance you could list the configuration settings as it’s a mine field when you start looking into it cheers Gary
Hi Andy I have a Stealth Bomber clone Bike 72 volt battery 5000 watt hub motor her motor when I give it throttle is slips what causes that can you help me
Hey Andy, I noticed that there are those cool looking cylindrical connectors for the brakes, display and throttle. If I wanted to wire up a different throttle with normal pin connectors, would that be possible? Also, how would you set up Regen braking? I've built a 1500w ebike and it's great, but I just want the power of the qs 205, but the sabvoton controller is really intimidating! You're awesome!
can you set it so it dumps a lot of power at start ? or smooth ? My current controller seems to have a 1 sec delay before it dumps all power. I want that fixed ! Also whats your bikes SPECS ? THANKS
I ALSO LIKE THE BOLTS TO CONNECT THE WIRES BUT I THINK ONCE INSTALLED ID BE WORRIED UT OTHER WIRES BANGING INTO THE METAL BOLTS OR LEANING ON METAL FRAME IT COULD SHORT THAT WHOLE CONTROLLER OUT AGAIN NOT SURE BUT A PRODUCT IM NOT AFFAITED WITH BUT USE ON EVERT ELECTRIC PROJECT IS liquid e-tape you literally paint it on and it dries like a rubber cement type but you can use it on the ends of an hARDNESS LIKE THE 2 CABLES YOU WOULD MAYBE OF CUT OFF FOR SAFETY THE ONES THAT YOUR NOT USEN BECAUSE YOUR NOT USE THE BRAKE LEVERS WELL YEa just use liquid etape at the end it's not bulky and if you later wanna use that connector just warm the etape liquid up and itll melt away exposing the metal connectors ITS GREAT FOR LIKE THE CONTROLLER BOLTS THat you cant use etape on or shrink-wrap on good luck hopefully i showed my guru a new ideal maybe #gurukirby #KIRBY #NOVACUUMSKIRBY #NOSUCKINGJUSTGOING #MYMAN
10:40 BEST setup procedure for an ebike entirely assembled. Good application in mathematics and algorithms to get the BEST parameter settings for the controller for the e-motor to turn with the BEST and SMOOTH acoustics =(sound and waves and frequency). ❄️ Even lots of engineers don't know what ALL THESE MANY different "paramaters" really mean to get it right and perfect in turning around in magnetics.❄️
hi Andy, I have a Sabvoton with the old TFT display (made by MQCONN) I'd like to upgrade to the one you have and finding a bunch online that look like it but only up to 48V or 60V and for Bafang only. is it possible to purchase this display seperately?
I’m hoping to buy the 60A Sabvoton controller from your site next week, What are the chances of getting stung with the import tax etc?...If so how much will this likely be? I’ve got £350 saved up. I’m looking forward to trying it out myself and comparing it to the square wave 👍
Did you say what kind of range you are getting these days? When you are at wide open throttle what kind of voltage sag are you seeing also? I finished my setup and have put a 150 miles on it so far. I got 42 miles out of 25Ah on my last ride. I have the low voltage cutback coming in a little too soon at 3.3-3.4Vpc but I can easily get 50 miles of mixed riding with no regen at an average of 30-35mph if I use 30Ah of my 36Ah pack. I have no limits on power other than motor temp, and low voltage, but I find it really hard to not just mash the throttle every chance I get. With my suspension and 19" mx wheels it feels great at speed. 30% flux weakening is enough to get me to 55mph. I also wanted to setup off throttle regen, but it seems that will be a bit more complex to setup than I first thought. I finally found a 100v supply 12v 25a output power supply, so I need to install my lights soon, and I need to figure out how I am going to control regen. I have the programming mostly dialed in now, and the ASI controller will let me pull 8kW/93A wide open. I would like to upgrade to the BAC4000 so that I can pull 150 battery amps, but there is no way the Crystalyte crown will eat that without choking.
Hey Andy, You are so knowledgeable about these ebikes I live in Vancouver, Canada and just got one of these ebikes with the Sabvaton 150amp controller, how do you get the regen braking to work?
If you are running 72V, it won't work if your battery is over 78V (it's to protect the display from the high regen voltage). Once your voltages drops to below 78V it should kick in if you have the right settings.
so i had a lot of probems with my display, now i figure out that my new sollution works, but i didn´t drive it jet. the display works now with 48v because it´s only made for max 85V i hope Andy you read this and i get an answer for my question: will the brake from the controller charge the battery if the display shows only the 48V but the controller run at 88V?
Yeah, the display is not really made for 72V nominal battery, so they limit the regen to protect the display. I found that regen would only work when battery dropped to 78V (88V-10V). I tried to return it and couldn't get them to accept their lack of claimed performance.
Andy, Is it correct that a 72150 with color screen and waterproof connectors does not include wires for temperature, variable regeneration, or an ignition wire. It seems the motor is plug and play which is great but does not support many functions. Thank you for the videos! Well done sir. You have inspired me to build one here in the colonies.
Hi, it can monitor the temperature of the motor (can be seen in app) these controllers have progressive regen which works with the included brake levers. The ignition is turned on/off using the power button on the handlebar mounted switch set.
Hi Andy, i have a Adaptto Max-e now, but wil replace it with something else... This 72150 unlocked looks good, but i heard them tell me it has no variable regen? While yours has it? Is this a special option?
Anyone know why the wheel settings shown at 15:08 are so simplified? Those few wheel size presets will likely *not* match the actual size tire. The preset cannot know the actual tire thickness which varies by user and will greatly affect the speedometer & odometer calculations. Other ESCs allow setting the wheel size to the nearest centimeter just with a simple up/down clicker. Small inaccuracies in the wheel size will cause the ESC to calculate quite incorrect speeds and thus distances will be off as well. I am really perplexed at this over simplification of this crucial configuration parameter.
Hi Andy many thanks for the reply to my earlier questions. I'm building a bike like yours with an 8000w hub motor. What's the biggest size battery that I can fit in the frame. Ie series and in parallel. Many thanks Brian
Oooh now there’s a question! The common size is 20S10P of 18650s, this leaves enough space for good packing and a Sabvoton 72150 controller. You could fit more in there if you were really clever with the pack design but you are always restricted to the way 18650 packs are configured. 8000W continuous requires a VERY solid battery pack design with at least 10mm x 0.10 nickel cell interconnects. I am currently planning a new high power battery build using 26650s and will be covering this in an upcoming series! Stay tuned!
How's is it going I'm a fan of your Channel will have an issue I have bafang control that you have and the same display but the display doesn't turn on Bluetooth doesn't turn on, but the throttle it lights up let me know their power by chance you know what is the issue, controller doesn't turn on as well the red light doesn't show up
do you think it's worth upgrading from a cycle analyst I have the same controller but I was thinking of ditching the cycle analyst and just buy tft lcd would that work?
Hi Andy, Great blogs and an awesome upgrade! I’m also thinking of using the new sabby upgrade on my next build. Bit worried I couldn’t see any way of attaching the controller to the underside of the frame as I won’t have room to fit it inside the new frame. Are there any attachment holes on the controller? I remember you got the last ones cut off.
Thanks! Yeah it needs some thinking about. The controller is quite wide with the tabs on (the ones I got cut off) but with those left on it does give you a way of mounting it.
can you do a video on regen, some things i'd like to know, does it give a significant addition to range, does it degrade the battery, if so, (something I was contemplating) switch regen to charge a secondary battery and when primary pack has cut out switch over to secondary and vice versa?
It would work to an extent but you might as well put the power back into your main battery and save yourself the hassle of having high power relays to handle the extra battery. You could use the space better by just adding a bigger battery. Regen produces power when you brake or coast. It will never be a lot of power unless your rolling down a mountain but it can be useful. If you could use the regen power to charge a super capacitor though you might be on to something! Hmmm you got me thinking now!!!
Using a supercap would be amazing, it would be good to have a separate regen system for times when you have to slow down or stop for stupid things like people/dogs in the way, or at junctions or going down hills where there is no run off and you loose all your speed/energy to heat in the brakes, to then pull the stored power out again to get back up to speed, could have a separate hub motor on the front wheel for this purpose. On a side note, I had a Chinese ebike which was a DC hub motor and it can work as a generator as well as a motor.
Next video should explain it, but basically all the settings look correct. I tamed the acceleration a bit but still enough to pull power wheelies, I’m no better at them and nearly came off earlier trying to do one!!!😅
Hi Andy, does the Sabvaton only work from 72v and up or can they run on lower voltages? I'll get into trouble with that much voltage,...... All the best Charles.
Can you do me a favour? Will you check with the vendour if the controler has a line for switching the lights on and off VIA the controller, the reason I ask is that I physicaly had to make that for my kt controller, it also has a display light that is supposed to switch the lights on and off but it did not so I would like to have that built in with it from the factory if possible. Thanks Andy. Regards Cheers.
I have a TFT display that came as part of my kit. Its a different configuration, but really cool. Not sure what type of controller I got as its all in Chinese.
Cool! Yeah I think these are becoming quite popular now. Like a lot of the Chinese stuff, some clever person designs it and then every company copies it!
Nice bike brother. Kelly includes a bag of those aviation connectors. Nice screen. Omgoodness, a display with no continuous Wh/mile or km, no current Wh/mile or km, No Wh used since last charge, no lowest voltage since last charge -- like all the important stuff is not there.
What I think you should do is find a few OLD friends that fall in the category of Café Bikers who are adept at frame, brakes, and suspension. You're at the threshold for aerodynamics to make a real difference. YOU MAY NEED STILL STOUTER BRAKES!! Now, what happens if you use the Power Level button as a gearbox? If so, I'll wager that 97mph reading you got at first, would be WELL within your reach. You are in MOTORCYCLE territory now, and I imagine that on the bike You're riding at present could prove slightly terrifying. So now you have to consider lowering the center-of-gravity, lengthening the wheelbase slightly, and start thinking like you have a BSA, Norton Manx, or a Triumph. Real Isle-Of-Man type stuff. I wish you and I were neighbors, so I could play TOO!
That is sweet, the wrap has tidied it up nicely..... Im loving this ebike weather. Ive just completed my first conversion, its so addictive. I think my next route is to get a good frame and piece it together over winter. Thanks for the great tips.....

The inches on your wheel are your circumference so measure from ground to the top for your number.

I need a display which light up or visible at night
what camera is that ? proper go pro or one of the cheap knockoffs on amazon for 1/10 of the price ? your footage is really good
Which motorcycle is that, and how much was it to insure?

The torque is insane if u set ur setting right got mine up to 60mph
Hay Andy do you know how to unlock a sabvaton controller
Love the channel and the bike builds keep it up

Can i use pedal assist with sabvoton?
you can use a capacitor inline with the batteries to stop huge voltage sag on the batteries and improve responsiveness
Yeah been thinking that, would need a pretty big one (or bank of supercapacitors) to absorb that amount current!
It's a big production
Do You cut case ears to fix controller on the frame?
hi Andy, I have a Sabvoton with the old TFT display (made by MQCONN) I'd like to upgrade to the one you have and finding a bunch online that look like it but only up to 48V or 60V and for Bafang only. is it possible to purchase this display seperately?
Hey man my sabvoton takes about 30 seconds from when I turn it on until it will give full power. You know anything about that? Thanks.
I’m hoping to buy the 60A Sabvoton controller from your site next week, What are the chances of getting stung with the import tax etc?...If so how much will this likely be? I’ve got £350 saved up. I’m looking forward to trying it out myself and comparing it to the square wave 👍
Did you say what kind of range you are getting these days? When you are at wide open throttle what kind of voltage sag are you seeing also?
I finished my setup and have put a 150 miles on it so far. I got 42 miles out of 25Ah on my last ride. I have the low voltage cutback coming in a little too soon at 3.3-3.4Vpc but I can easily get 50 miles of mixed riding with no regen at an average of 30-35mph if I use 30Ah of my 36Ah pack.
I have no limits on power other than motor temp, and low voltage, but I find it really hard to not just mash the throttle every chance I get. With my suspension and 19" mx wheels it feels great at speed. 30% flux weakening is enough to get me to 55mph.
I also wanted to setup off throttle regen, but it seems that will be a bit more complex to setup than I first thought.
I finally found a 100v supply 12v 25a output power supply, so I need to install my lights soon, and I need to figure out how I am going to control regen.
I have the programming mostly dialed in now, and the ASI controller will let me pull 8kW/93A wide open. I would like to upgrade to the BAC4000 so that I can pull 150 battery amps, but there is no way the Crystalyte crown will eat that without choking.
How much is the insurance on your emotorbike? Mine is about £165 /yr
can you show me the regen lever you have please :}
Hey Andy,
You are so knowledgeable about these ebikes I live in Vancouver, Canada and just got one of these ebikes with the Sabvaton 150amp controller, how do you get the regen braking to work?
If you are running 72V, it won't work if your battery is over 78V (it's to protect the display from the high regen voltage). Once your voltages drops to below 78V it should kick in if you have the right settings.
Cool bike and vid. Thanks for the upload.
Can it work wit out the cycle analyst???
What tireas are those? I want those for my ebike in 27.5"
have you at any time managed to activate the switchable Speed limit with this set up? looking for help
You need a 3-way switch, NBpower on Amazon makes one specifically for the Sabvoton plug and play.
so i had a lot of probems with my display, now i figure out that my new sollution works, but i didn´t drive it jet.
the display works now with 48v because it´s only made for max 85V
i hope Andy you read this and i get an answer for my question:
will the brake from the controller charge the battery if the display shows only the 48V but the controller run at 88V?
Yeah, the display is not really made for 72V nominal battery, so they limit the regen to protect the display. I found that regen would only work when battery dropped to 78V (88V-10V). I tried to return it and couldn't get them to accept their lack of claimed performance.
What do you call that thing? I mean what do you consider it to be? Bike, ebike, electric motorcycle? What are you going for and where do you ride it?
Andy, Is it correct that a 72150 with color screen and waterproof connectors does not include wires for temperature, variable regeneration, or an ignition wire. It seems the motor is plug and play which is great but does not support many functions. Thank you for the videos! Well done sir. You have inspired me to build one here in the colonies.
Hi, it can monitor the temperature of the motor (can be seen in app) these controllers have progressive regen which works with the included brake levers. The ignition is turned on/off using the power button on the handlebar mounted switch set.
Hi Andy, i have a Adaptto Max-e now, but wil replace it with something else...
This 72150 unlocked looks good, but i heard them tell me it has no variable regen?
While yours has it? Is this a special option?
Hello can you help my with my sabvoton with Regen brake i have 84v battery and the regen kik in only at 81v if i am at 82v i dont have it way? Thx
Yes that’s correct, you shouldn’t have it when your battery is fully charged or near fully charged as you can damage your battery. It sounds correct.
Hi Andy, I've got the 100a sabvoton with the same tft display screen, how is the screen ? Is it decent.?
The controller doesn't fit in my frame lol so I'm having to modify the Stealth bomber frame slightly
Hi Andy, did you find out how to program the 12345 power levels? I can't figure it out 😂 thanks
andy how do you change the top speed settings on the lcd pas mine dosent have the advanced functions for some reason
One more thing were you able to turn flux weakening past 50amps?
Anyone know why the wheel settings shown at 15:08 are so simplified?
Those few wheel size presets will likely *not* match the actual size tire. The preset cannot know the actual tire thickness which varies by user and will greatly affect the speedometer & odometer calculations. Other ESCs allow setting the wheel size to the nearest centimeter just with a simple up/down clicker. Small inaccuracies in the wheel size will cause the ESC to calculate quite incorrect speeds and thus distances will be off as well.
I am really perplexed at this over simplification of this crucial configuration parameter.
Links seem to not work anymore.
Hello. Love the Bike. What kind is it? Have a site?
Hi Andy many thanks for the reply to my earlier questions. I'm building a bike like yours with an 8000w hub motor. What's the biggest size battery that I can fit in the frame. Ie series and in parallel. Many thanks Brian
Oooh now there’s a question! The common size is 20S10P of 18650s, this leaves enough space for good packing and a Sabvoton 72150 controller. You could fit more in there if you were really clever with the pack design but you are always restricted to the way 18650 packs are configured. 8000W continuous requires a VERY solid battery pack design with at least 10mm x 0.10 nickel cell interconnects. I am currently planning a new high power battery build using 26650s and will be covering this in an upcoming series! Stay tuned!
How's is it going I'm a fan of your Channel will have an issue I have bafang control that you have and the same display but the display doesn't turn on Bluetooth doesn't turn on, but the throttle it lights up let me know their power by chance you know what is the issue, controller doesn't turn on as well the red light doesn't show up
Would the 60amp version of this work on a 1000w to 2000w setup I have 2 hubs on different bikes
do you think it's worth upgrading from a cycle analyst I have the same controller but I was thinking of ditching the cycle analyst and just buy tft lcd would that work?
Hi Andy what's the app your using to connect to your sabvoton. CheersBrian
It’s called MQCON, it’s on the App Store.
Hi Andy what watt size hub motor are you using on the rear wheel. Cheers Brian
It’s the 5kW on our website here: www.cloudsto.com/store/andy-kirby-e-bike/qs-v3-5000w-motor-with-19-inch-motorcycle-rim-detail.html
Hi Andy, Great blogs and an awesome upgrade! I’m also thinking of using the new sabby upgrade on my next build. Bit worried I couldn’t see any way of attaching the controller to the underside of the frame as I won’t have room to fit it inside the new frame. Are there any attachment holes on the controller? I remember you got the last ones cut off.
Thanks! Yeah it needs some thinking about. The controller is quite wide with the tabs on (the ones I got cut off) but with those left on it does give you a way of mounting it.
it's that fun all the time with a proper motorcycle with an engine
That is the same display i just ordered for my BBSHD FULL SUSPENSION EMTB,
can you do a video on regen, some things i'd like to know, does it give a significant addition to range, does it degrade the battery, if so, (something I was contemplating) switch regen to charge a secondary battery and when primary pack has cut out switch over to secondary and vice versa?
It would work to an extent but you might as well put the power back into your main battery and save yourself the hassle of having high power relays to handle the extra battery. You could use the space better by just adding a bigger battery.
Regen produces power when you brake or coast. It will never be a lot of power unless your rolling down a mountain but it can be useful.
If you could use the regen power to charge a super capacitor though you might be on to something! Hmmm you got me thinking now!!!
Using a supercap would be amazing, it would be good to have a separate regen system for times when you have to slow down or stop for stupid things like people/dogs in the way, or at junctions or going down hills where there is no run off and you loose all your speed/energy to heat in the brakes, to then pull the stored power out again to get back up to speed, could have a separate hub motor on the front wheel for this purpose.
On a side note, I had a Chinese ebike which was a DC hub motor and it can work as a generator as well as a motor.
We ❤ Sabvoton 👍
Who is Tony? Who is Tony!! Only the legend that is Vortecks!
4 sabvotons and i am so done with this chinese piece of shit . asi FTW
hey any did you sort the mad acceleration out ? was it pulling mmore power than the screen was displaying ?
Next video should explain it, but basically all the settings look correct. I tamed the acceleration a bit but still enough to pull power wheelies, I’m no better at them and nearly came off earlier trying to do one!!!😅
Level 5 and 20s of high discharge lipo on a qs hub would melt through time like doc brown.
This suckers electrical !
It sure would! 😅
This sabvoton support PAS sensor?
Do you have switches on your hydraulic brake levers? 🤔 I’m know they are needed for cruise control
Do you know if the display can exceed 9999W?
Hi Andy, does the Sabvaton only work from 72v and up or can they run on lower voltages? I'll get into trouble with that much voltage,...... All the best Charles.
Hi Charles yeah they work from 36-90V so ideal for all the common pack voltages.👍
I know what I want for xmas..... 😁😁😁
Can you do me a favour? Will you check with the vendour if the controler has a line for switching the lights on and off VIA the controller, the reason I ask is that I physicaly had to make that for my kt controller, it also has a display light that is supposed to switch the lights on and off but it did not so I would like to have that built in with it from the factory if possible. Thanks Andy. Regards Cheers.
I have a TFT display that came as part of my kit. Its a different configuration, but really cool. Not sure what type of controller I got as its all in Chinese.
Cool! Yeah I think these are becoming quite popular now. Like a lot of the Chinese stuff, some clever person designs it and then every company copies it!
Nice bike brother. Kelly includes a bag of those aviation connectors. Nice screen.
Omgoodness, a display with no continuous Wh/mile or km, no current Wh/mile or km, No Wh used since last charge, no lowest voltage since last charge -- like all the important stuff is not there.
Thanks man!
Thanks man! Got me thinking now, are the Bluetooth modules with the CA connector still available? I’ve got a CA connector installed in my bike.
Nice like it I know this is not in your League I have a 36 volt 500 watt controller but going to 36v
1000w would it be more speed or torque
More torque and probably a bit of top end too.👍
andy can i buy some of your bikes?
Can you help me solve a problem on the sabvoton controller
Try set it on the 1 to 9 power levels insted of the 1 to 5 it makes it less aggresive
What I think you should do is find a few OLD friends that fall in the category of Café Bikers who are adept at frame, brakes, and suspension. You're at the threshold for aerodynamics to make a real difference. YOU MAY NEED STILL STOUTER BRAKES!! Now, what happens if you use the Power Level button as a gearbox? If so, I'll wager that 97mph reading you got at first, would be WELL within your reach. You are in MOTORCYCLE territory now, and I imagine that on the bike You're riding at present could prove slightly terrifying. So now you have to consider lowering the center-of-gravity, lengthening the wheelbase slightly, and start thinking like you have a BSA, Norton Manx, or a Triumph. Real Isle-Of-Man type stuff. I wish you and I were neighbors, so I could play TOO!
