you cannot buy it already upgraded unless you buy it from Craigslist or some dealers will upgrade it. you have to install the kit yourself, it comes with instructions.
You dont need to bypass your battery to install the controller but you can only run about 10% more power than stock without bypassing the battery so it would be a waste of the controller.
Hey Sage, love the content, could you show exactly how you added fork oil to the front suspension? I was doing jumps at malaga today and noticed how incredibly dry everything is, thanks
the fork uses a sealed cartridge damper which has its own oil. Sage is talking about adding fork oil to the lowers which contain the sealed cartridge damper and where the most friction is.
Dude -great lead footage... missed my chance at a E-moto bros BAC 4000 drop even tho i was on it. Thanks for the info! Would love to hook up (looks like you are in san mateo Co. -I'm in SanRamon) after I heal from my fall🤕 - I get another Sur Ron on Monday too Wifey/ Buddies will get to ride after with me now! Going to eventually get a Bac 4K and try the fork oil!
anything will make it better, but I did 15cc of rockshox 15 weight in each side. The seals aren't designed to handle oil so they weep a little with 15 weight. Perhaps 20 would be better. any brand.
Yes. That being said, bypassing the stock battery puts a lot of strain on the battery, and I wouldn't run it like that for longer than a few months, until you can save for a proper battery designed for higher amperage
Hello I just installed my bac4000 with an original battery with bypass. Is it normal that the display always shows 100 percent even after driving because the Egg Rider says something else.
Hey, I'm thinking about upgrading my Surron. If i just by the BAC4000 and use it with the stock battery, will that increase my Top Speed? or do i need a 72v Battery with the BAC4000 to increase Top Speed? I'd appreciate your help. Thanks!
if you bypass the stock battery and run it it 7000w as many say you can, then you are running it at the literal limit of the cells (10 amp discharge). I would run it at 6-6.5kW.
@@sagesends What about if i don't bypass the battery and just upgrade the controller, will that benefit me at all? if so what would the Top Speed be as that's my main focus. Just increasing the Top Speed.
in this video I was running 6500w, 12% weakening, 430 phase amps. I wouldn't recommend pulling the full 7000w from the stock battery, it's pushing it to it's absolute limit (10amps per cell) and I defo so some loss of battery health (surging at low battery n stuff)
@@sagesends how long did you run it with stock bypass until getting the chi 60v? I plan to get the same battery eventually but keep telling myself I will rock the stock battery for a while. Am I kidding myself?
oops, I mean battery. Without bypassing you only go from 4000 watts to 4800 watts and the jump isnt super noticeable. I ran mine at 6000 watts with the bypass and that felt really good.
Good review and couldnt agree more with everything for the BAC4000 and the front suspension. I have the same controller from emotbros but I can run 9kw bc I have a parallel pack but honestly unless im on the mx track its too much for trails when pushing over 400phase amps at that power, usually stay at 7kw after trying everything from 5-9kw in 1kw increments. My only issue is i did blow out my rear shock but it was very obvious when it happened. I had the RST forks and same thing added some oil and they were better but since then ive gone to ktm65 forks bc I do alot of fast riding with jumps but for trails the stock stuff does fine
@@sagesends yep I plan on a DIY battery capable of about 10-12kw but just going to keep it low around 5-7kw most of the time so I get more range and dont stress the cells as much. I do races long enough to need two stock batteries when on the stock power so will really struggle with more power

Sick vid! Ripping that trail man. Don't think I could keep up lol. But you running stock battery? I'm looking at getting the bac400 but I ride mostly street. Want something to give me power to keep the front wheel up a little longer
stock battery yeah. Run it at 6kW though, 7kW is the absolute limit of the cells and puts them through a lot of stress. You'll notice fairly rapid battery degradation
I added about 15ml a month ago, it leaks slowly from the seals as they are not very good. not fast enough to drip, I just wipe it off every few rides. Absolutely worth the performance increase though, they feel better than when you first get them
@@sagesends that means you're seals are degrading from the oil Maybe you can replace the seals that's made for oil bath forks the seals are 36mm with an o ring kit
@@sagesends ah cool thanks a lot for the answer, yeah I figured it probably ain't too much otherwise the pressure would blow the fork seals out but I'm not too experienced on bicycle shocks, only motorcycles and I'm getting mine tomorrow :D
you gotta do a BMS discharge bypass to do more than 4800 watts though. BMS is still active for charging though so it doesn't do much harm to the battery as long as your not asking too much from it (no more than 7000w)
I'm glad I found your channel. My Sur Ron x black edition arrives on Wednesday. I'm stoked. On a side note, please don't ever talk about politics on your channel. It's the reason I unsubbed from the last sur ron channel. Politics are dumb.

honestly range doesn't take a massive hit since you don't use all the extra power all the time, esp with trail riding. I got about a 25% decrease in range, but if you're economical it actually gets more range as the motor controller is more efficient
I added a watt meter to my new Surron right away and I can tell you it pulls 80 amps so 80 x 60=4800 watts. If your pulling 7000 watts, then at 60 volts (which is really a bit high since at 80 amps the battery sags 5-6 volts), then your pulling about 115 amps..and the Panasonic PF cells are rated for 10 amp continuous, so your at the limit of the cells. Obviously you bypassed the load side of the BMS, because it limits the bike to 80 amps. I have a 150 amp BMS coming which I am going to replace the stock BMS and build a 7 p extender pack with the same BMS and boost my BAC 4000 to 140 amps. By the way, the battery started cutting me out at around 54.5 volts which is too conservative, (3.4 volts per cell) especially if you reduce the power at this point a bit..look at the discharge curve of these cells (which I have made many packs from). The algorithm they are using for this is looks like its based on a discharge curve of .2 C. If you look at the 1C discharge curve, 3.4 volts = about 40% left, so from 3.4 volts to 3.30 volts you still have 25%. Doing a conservative cutoff, extends the life of the pack and prevents any potential damage due to extreme amperage discharge.
Yes I have noticed that I cannot pull more than about 5000w when the battery is below 25%. Even though the BMS is bypassed the cells themselves cut power. I have since dialed it back and am waiting on a new battery that I ordered. The battery runs at about 66.5v fully charged
@@sagesends The cells themselves dont actually cut power, but as they get to 3 volts each they start sagging more hence giving you less power (Example: 3.2 volts sagging to 2.7 volts each x 16 =43 volts x 115 amps = 4968 watts.... Without anything on the load side of a BMS there is nothing from completely flattening the cells, hence damaging them unless you have a voltage cut off via the controller or cycle analyst.
@@sagesends Ya probably the BAC 4000...Mine is from Teznic and they said its very complex and has a million parameters...but they can set LVC to whatever I like, in my case it would be around 51.5 volts.
Hi, I have a Sur-ron. Being 6ft3in I raised the seat and lowered the footpegs. Not sure if the ridingexperience changed that much for me. But I am an amateur ( can`t even do wheelies yet). What would a raised bar do for me? Or what does it do for you ( you are obvious a good driver)? BR Jan hansen
Allows a much more comfortable and balanced seating position. You are less hunched over the front of the bike. Its pretty much essential for anyone over 5'6" to get riser bars for this bike. I recommend protaper 3 inch rise for your height. It makes the bike much more comfortable and easier to control
of range. either that or you misunderstood what I said. the bike is peppy from 15-25 mph. from 25mph to 42mph (the real top speed) it's pretty slow. That's where the bac400 comes in
@@sagesends yea re watched that’s pretty good I was getting about 30miles range on my sock battery on my sting now I have GLE bac 8k and 72v shit rips sadly blew my motor haha hit a top speed of 72.4 tho haha gps new motor comes Wednesday
Range depends entirely on what you are doing. If I switched into eco mod I could get 45+ miles with the stock battery. If I was gassing super hard on Enduro trails i could kill the battery in 15 miles. Providing a "line in the sand" range estimate for ebikes is dumb since it's use-case dependent. Sting has a 39aH battery instead of 32 so it's got an edge there. Surprised you blew a motor, maybe the sting motors aren't as reliable? hopefully it was a dud. Seen a lot of people run sur rons at 13+ kW and hit 75 regularly with no blown motor, since it can handle 120c without much trouble
With the fork oil do you still feel the need to get better forks? Do you feel comfortable doing lots of jumps? Your jump in this video was impressive and I was surprised you did it with the stock forks. Basically I want to do what Trent Palmer does in his sur ron videos and am curious if just adding fork oil would be sufficient. I'm totally going to ge the bac4000 now. Great vid man.
The issue with the stock fork I think is the ramp up. It goes through the first 120mm of travel super fast, then the last 80mm of travel ramps up super hard, to the point where I've never used the last 20mm of travel even with drops to flat. This is good for trail chatter but not great for big hits. The reason I say get BAC4000 first is because with the fork oil the stock suspension is more than sufficient, although not ideal. I will get a fork in the future, but I think the BAC4000 should be aquired before a fork, if you are needing to save up for each upgrade. If you have the expendable income, I would ofc do both
@@sagesends I wonder how it would be with adding fork oil and then stiffer springs, if available. I was hoping to get the bike to 7000kw. That's so I want. But I've been struggling trying to decide what to do with the forks. I don't want to spend another $1k+ on suspension. I've been Looking at pit bike forks, 85 forks, anything besides the expensive fox or dvo's
Yo sage! I'm currently 15 years old but im gonna get my license when im around 16.5, i wanna get a bike like yours but one thats legal on roads n shid, do you know any good options for like under 4k?

that's fair. If you want something to travel far and fast for cheap I would go with a gas bike. There is no electric bike under $4k with decent performance and range.
@@sagesends Yo sage! So i was looking around and i found an ebike that goes around 100kmh and its 3.6k, the channel is Ladi & Margaret, anyway, im kinda confused cause i think he tells you where to buy the parts from and then you build it yourself but i dont wanna risk spending 3.6k and then not knowing how to build it, also i heard it charges with like 12amps? isnt that way too much, like actually way too much? Also its his company so i feel like hes being biased to how good it is so i was wondering if you could tell me like how reliable it is

How much fork oil in each Shock mate ? Thanks
15ml in each side, not a lot. the seals can't handle the extra compression that a lot of oil creates (less air volume) and will weep oil if you add too much. Only works on the DNM volcano forks, the RST killah suffers from deeper issues than just chronically dry seals.

Sting has a 39aH battery instead of 32 so it's got an edge there. Surprised you blew a motor, maybe the sting motors aren't as reliable? hopefully it was a dud. Seen a lot of people run sur rons at 13+ kW and hit 75 regularly with no blown motor, since it can handle 120c without much trouble
Which fork oil do you recommend? My sur ron is delivering tomorrow and I hope I can get a BAC4000 in the next batch from E-moto Bros.
Rockshox 15 wt or fox gold 20 both work. Use thicker oil for more longevity and thinner oil for more performance
With the fork oil do you still feel the need to get better forks? Do you feel comfortable doing lots of jumps? Your jump in this video was impressive and I was surprised you did it with the stock forks. Basically I want to do what Trent Palmer does in his sur ron videos and am curious if just adding fork oil would be sufficient. I'm totally going to ge the bac4000 now. Great vid man.
The issue with the stock fork I think is the ramp up. It goes through the first 120mm of travel super fast, then the last 80mm of travel ramps up super hard, to the point where I've never used the last 20mm of travel even with drops to flat. This is good for trail chatter but not great for big hits. The reason I say get BAC4000 first is because with the fork oil the stock suspension is more than sufficient, although not ideal. I will get a fork in the future, but I think the BAC4000 should be aquired before a fork, if you are needing to save up for each upgrade. If you have the expendable income, I would ofc do both
@@sagesends I wonder how it would be with adding fork oil and then stiffer springs, if available.
I was hoping to get the bike to 7000kw. That's so I want. But I've been struggling trying to decide what to do with the forks. I don't want to spend another $1k+ on suspension. I've been Looking at pit bike forks, 85 forks, anything besides the expensive fox or dvo's
that's fair. Just remember this bike has an mtb standard headset so anything without a 1"1/8 steerer will need a special adaptor
@@sagesends yeah I know it'll need some work... Thanks for your video helped a lot. Super excited to get the bac4000
Yo sage! I'm currently 15 years old but im gonna get my license when im around 16.5, i wanna get a bike like yours but one thats legal on roads n shid, do you know any good options for like under 4k?
build your own. check out my video about the electric cruiser I made. Its $750 and will do 38mph with a 60 mile range
@@sagesends oh damn thats cheap and fast, imma take a look but ill probably still keep looking for one that goes around 100kmph cause i gotta travel cities when im older lmao
that's fair. If you want something to travel far and fast for cheap I would go with a gas bike. There is no electric bike under $4k with decent performance and range.
@@sagesends aw damn, thanks for the response, i'll look into it
@@sagesends Yo sage! So i was looking around and i found an ebike that goes around 100kmh and its 3.6k, the channel is Ladi & Margaret, anyway, im kinda confused cause i think he tells you where to buy the parts from and then you build it yourself but i dont wanna risk spending 3.6k and then not knowing how to build it, also i heard it charges with like 12amps? isnt that way too much, like actually way too much? Also its his company so i feel like hes being biased to how good it is so i was wondering if you could tell me like how reliable it is
dude how much do u have into it so far ??
price of the bike plus $850 for motor kit and $100 for pegs and bars
Hey man- great vid. Just curious (maybe I missed it), what kind of top speed (on the street) do you get with the 4000 and stock 48?
62mph with 15% field weakening
Bro you were flying at the start 😂
How much range do you have with the stock battery and the bac4000 when driving like this? Sick driving btw ur a maniac haha.
somehow similar range to stock, about 10% worse. ~15 miles like this
@@sagesends oh haha i get around 30 miles on a full charge right now so thats half haha
I got ~17 miles stock because I ride pretty hard haha. why would I say 10 percent less than stock if I got 30 stock haha.
@@sagesends yea I bet haha, I havent pushed it that hard offroad haha
haha 🤖
Not if you have a RST fork lol it’s not good at all. New fork and asi controller are two best mods I’ve done so far
you gotta put fork oil in it then it's fine for most moto stuff. No small bump sensitivity like a 40 but still plenty good for big hits and chunder.
@@sagesends tried that and adding a small socket to space out coil. Still rode like trash 🤷🏻♂️ wish my surron came with the DNM instead
Of the RST, but glad I have a fox40
ohhh word youre right, I have the dnm and it's actually fine but yeah I've heard the RST had bottoming out problems
0:02 say's it all Lmao ⚡💥
sucks u cant find one anywhere and e moto bro site doesnt even work anymore
yeah I got super lucky to be able to get one from emoto. Refreshed the page as soon as they went live and they sold out in like 30 seconds
Wow
Wait! There's no fork oil in stock!?! My jaw literally dropping open at that
yup lol
how does BAC4000 Upgrade affects battery life?
you're putting down 75% more power so it ofc burns through battery quicker
Hahaha who cares. Sorry. Fast is just so much fun.🐜billy
Hello nice video. Are there any problems with the bypass when charging the battery. Are the cells balanced despite the bypass?
yes, the BMS is still used for charging so add long as you charge fully the cells balance
Great vid did you add bac 4000 and have stock battery bypass, cheers.
if only my battery and controller ever come -.- 4 weeks now
sheee my guy, yeah everything has been slow to ship ever since Corona
😎
Is the battery stock and also what other power upgrades do you have on this bike?
battery was stock in this video, not sure what other power upgrades there are. sprocket is stock too if that's what you mean
Heheheheh
Hi, with the bac4000 and running the 7kw tune…is that a stock battery not bypassed?
bypassed ofc, stock limits you to 80 amps or about 4800 watts
On stock battery still?
yes
@@sagesends not bypassed ?
