83 Miles !!! That"s more than enough for daily commute, considering full on throttle. I must say, you have done a good job building it. Hands down this is The most nicest DIY EV video series I have seen... Huge love all the way from India... Keep Posting bro !
I am building this one in Pune, will pick up an old splendor or cd dawn chassis, already have got the part from alibaba, it will be fast and sweet. Trying to cut down on battery cost
hmm yeah but the really good non Chinese ones are super expensive like $22,000 - $85,000 price range, have top range of 125 miles, a 0 to 60 of 3 seconds with a charging station time of 20 to 30 minutes, weigh anywhere from 460 to 665 lbs, and have a top speed of 125 to 150 mph (they actually put a built in limiter on the ones that 150 mph for battery consumption and safety reasons so technically they could go even faster if that limiter was off).
I'm really impressed with the performance and range increase you got with these mods, and someone else may have mentioned this, but those 18650 batteries will start giving even more range after 8 or 10 full charge/discharge cycles. That said, you should get close to 100 mi. at near full throttle, and possibly as much as 150 mi. in town. Nice work!! ;-)
It uses the same voltage at low speed as it does at high speed because . However it uses less current at low speeds than at high speeds. Battery charge & discharge rate is governed by Coulomb's Law. I'd have to move the rear brake to the right pedal, especially if riding conventional bikes also. A brief moment of subconscious confusion could lead to a front brake only emergency stop crash when later riding a conventional bike.
Been watching what you have done here and am more than impressed, I used to be a biker untill I had a nasty little collision that broke my knees, This brings me to what I am thinking, Electric wheelchair users are ripped off all the time by the major firms that build them, I think you could do a better job than they can probably at a far better price. Just an idea but would love to hear your thoughts on the matter. Keep up the great work
Thanks for taking us along for a ride with the development of your e-bike. As the battery industry gets more involved with graphene batteries or graphene hybrids, interested to know if you guys would consider upgrading the cells to those. Totally agree on minimizing regen braking as that wears out the battery quicker... some regen brakes are known to pump up absurd amperes back into the battery just over a short duration of a few seconds. One of the ways i setup my e-scooter was to only have minimal regen braking kick in only when the brakes are actuated by tying up a switch to the brake lever/light. This would definitely call for an adjustment to riding style, but it allows me to coast where possible and prolong battery life.
these are so dope wish i could afford to get one of these would save so much money getting to work, i know what im saving for! E-bikes are the future!!!
The reason electric cars can fast charge is because the high voltage they use. 400v is fairly standard, the industry is trending towards 800v though. I charge my ebike with a bigger charger than that so you're all good to move up to something way faster. Lots of chargers with adjustable current too so you can quick charge or slowly charge overnight. Just remember if charging overnight, lithium batteries do not suffer trickle charging well at all. It's a real sweet ride. it'll take you a while to iron out the bugs and get it how you like it, but once you do, they just go and go and go. It's astonishing how little maintenance they need. The only thing I'd change, is the controller. The config for it is barren. I forgot how bland kelly controllers are. Sure, they're reliable and work well, just lacking many tweaks and parameters that make fun happen. Enjoy your bike, but keep it in the back of your mind, if you want the dank nooners, upgrade that controller some day ;) Oh btw, awesome battery, I was sceptical of the chinese cells, but it's running pretty damn good!
What electric bike do you have and is it designed for faster charging? Keep in mind that faster charging gets the batteries hotter than when riding them so cooling is essential. Cars that charge with high voltage tend to have water cooled batteries to keep them cool. Inja has zero battery cooling so he has to keep the temperatures under control.
@@JasonWW2000 in some vehicles. Yes water cooling can help. I'm from the UK so not something that ever kicks in here lol. I'm not suggesting a 130kw charge, just more than 5A lol. I run a 24s7p made with lg hg2 cells and charging at 10A it barely increases pack temp by more than a couple degrees. It could take 28A max, but that would require active cooling.
Well thanks, that thing is totally usable around town for a whole week and should be good for non super long country runs. Once you get the overheat and safety shut down figured it will be awesome. 👍Onwards and upwards from here and looking forward to the super secret project.
Binge watched this whole series over the last couple of days and even forwarded it to a few friends as it has been a great source of information on a future project I'm thinking of doing. Hopefully I remembered to click like on all your videos to show my support. Couple of questions, firstly is there any chance of getting a detailed video from you and lord Curt on how to set up and programme the controller as a stand alone video. Secondly I have a super soco tc max electric bike and have found that the range varies a lot if when I'm going at it's top speed I don't leave the throttle pinned wide open, so was wondering for this test did you just keep it pinned once you were flat out or did you back off once up to speed? Reason I'm asking is I'm thinking of building a bigger capacity battery for it buy want to make sure it's going to be worth it before I do. Thanks and keep up the awesome videos
I could literally watch this guy's vids all day. Something about his voice and demeanor actually makes you feel like your right there in the garage with him. Humble outlook too. Good shit bro 👍

Good cells can take fast charge. As an example, Samsung 20s 18650 can 2A charge. If you charge and discharge correctly, they'll last three or more years. If you use crappy cells, they'll obviously damage easier as they're not rated for more than 800mah charging. Crappy cells also lack power and usually overrated on the amps and capacity. You end up damaging them without proper knowledge. My mate and me built an electric motorcycle. We were using Samsung 40T 21700 cells. We can get the cells charged to full in a few hours. Range is around 138 miles on average. One year on, cells are at 84% health.
Thank you Inja, you are very thorough, really enjoy watching your videos. Im in the process of upgrading my Grom clone, and your info is very helpful in the process.. 👍👍👍😎💪
As always I enjoyed this video. It seems as if you have built a very solid commuter bike. For a person that lives in a city, this would be perfect. It honestly looks like a lot of fun. With all the personal touches, I think this bike is turning out to be something pretty special. If ever one day you grow tired of it and would like to put it on the market, please let me be one of the first you contact. Very serious. I watched all of the videos from beginning to end so I know what it took to get this bike to the point if you have it now. I would not at all lowball you. No pressure and all patients. Just let me know in the late future because I know you're going to have fun with this thing for years LOL. As always be safe and have fun brother. I hope to see more of your projects very soon. Cheers!
Dude. I recognize where you're riding. I used to work at the DIY garage in Clovis. Moved away in February. Would have been nice to check out the bike. Ride safe and have fun.
Hey, that's pretty good range! This thing just keeps delivering! Is your fan on a thermostat? That might save you a couple of volts an hour maybe? As always, excellent video. 😁
At full throttle that range is up there with the best, although your home build battery is probably more than twice the size of a stock electric bike battery. My Evo is 40ah but at full throttle I can expect 25-30 miles range. In the City nearer to 50 miles.
I don't think the voltage sag is hurting him. The motor already gets plenty of power for it's size. Maybe it would give a bit more power to the motor right off the line? Improve the 0-30 time? It's possible I guess.
I have two questions. 1) re Brakes. What replacement pads/rotors would you need to use? 2) how much mileage did you get, once you hit 65v? Thanks mate, these are great videos, you should be rightly chuffed with what you've built!
Regenerative braking has to do with the hub motor switching between using battery power to accelerate and using the vehicle's momentum at speed to create power while decelerating to recharge the battery like an alternator would
If you want to keep the battery healty for as long as possible, if you do not normally need the full range. Consider only charging it to 80 or 70%. It is not only at close to empty that these batteries take extra wear from the charging cycles. As a reference and practical test you could try AccuBattery app to monitor the health of the battery in your phone.
Aerodynamic resistance, being dominant from 30mph upwards, rises 4 times by speed doubling, meaning, 60 miles at 60mph is 240 miles at 30mph!!! Almost... And additionaly, not steep voltage drop by city-driving.
I really enjoyed this build. The two of yous really make me want to build my own , but the bike I'm looking at is an E Boom . they are the electric version of a Grom clone. Maybe as your next build you do an Electric Grom clone . They only go 50 mph / 50 miles . see if you could increase the top speed while trying to double it's range.
Lithium batteries... thats how they roll, hold on strong to the very end... then drop like a rock. And a 1c charge rate (even 1/2C) will dramatically reduce your charge time if you can pull the amps and wont hurt your battery life. I have been charging lithium ions and li-poly batteries at 1c for over a decade. I dont push them harder than that though.
Im curious as to how much more range you would get at a more agressive regenerative brake setting. Like maby do a test at 50% then another at 100%. Awesome project! Ive been following it from the beginning. I love your videos man keep it up!
I don't know much about this things but I've had one as well, and I gotta tell you that you shouldn't leave them unused for awhile, when you don't have plans to go out just have the battery drain a bit and charge it again or else the battery life will completely just go down and down till it dies like what happened to mine
According to battery University, longer charges do stress more the battery than fast charging. The costant voltage, the heat produced by it has a negative effect on batteries.
No, it's the other way around. Faster charging requires higher amperage. This stresses the cells more and increases the temperatures. Slower, lower amperage charging gives less heat and longer battery life. The Constant Voltage part of the cell charge cycle (at the end) does not produce much heat.
83 miles, wow...thats pretty decent for a "own build" electric motorcycle! - If you now cut off these "0 to 60 in 2.7 seconds" to minimize the Amps (or the power draw peak) going from battery to the Motor to have longer range, could you test that? so then the bike would accelerate in 6 secs to 60 or something similar, but you didn´t have the power drop so much faster......is that an idea?
83 miles/133km. That was really a good range. In my country, 50-60km range on an electric bike is the best you can have. We don't have lithium batteries because it is so hard to find a legitimate supplier here and it costs too much. We only have lead acid batteries and it weighs a ton. 40km on my bike is good and I'm happy with it but 133km? I would love that bike more than I do with my girlfriend.
I solved the take off speed of my direct drive rear hub with a 750w front geared befang hub motor which is faster off the start helping rear motor to get to speed.
It's a pity that you don't have some sort of onboard Solar panel to extend the range or try to convert the kinetic energy into potential energy Via a scaled up alternator etc l
This is really kool. My dad and I build ebikes and so far the fastest we built is my dad 5K and we with the set up we hit over 70mph it’s capable of higher speed but just feels so scary
Cheers I enjoyed that, Being a shift worker could you do some city/suburb night riding, would like to see how the volts handle the lights being on, short rides 15 minute and a 30min ride would be great length and as I see it night riding/driving has less traffic so it should be fairly smooth on the battery, but with the lights on will it make much or any difference at all, Cheers again Ride Safe.
That range is pretty impressive. If you stuck to city riding you would probably get a lot more out of it. Shame the bike takes so long to charge though surely you can upgrade the charger to something a little better as waiting that long for it to charge certainly affects the usability of the bike. The guy who helped build the battery would probably know of a safe faster charger to use.
crazy how much you changed in the time you got this bike i been building my own little 350w electric scooters but i got my big ebike with a 55ah 16s 2p chevy volt battery running 6kw i get up to 85 mph but its getting dismantled because had the bike for almost 7 years now 3 motor swap 5 controllers and im afraid the aluminum frame may start to develop cracks i have for sure over 100k miles on it its been my daily driver for that many years i had 4 different batteries first was a 36v lifepo4 2nd 36v 14ah lithium 3 was a 72v 20ah and the 4th is the one im using 55ah 16s 2p wish i could get one of these i saw a motorycle like yours for 2300 in curacao but only says 30mph 30ah 72v battery lithium display is different and is set to mph so i may get it its a local store
Here's a suggestion as you like to tinker with these things, well you kinda got dropped in the deep end but never mind you learned a lot. Anyway to the suggestion, why not fit a top box on the back, and use it as a country ride battery pack, also a tank bag could be adapted for those country rides as well. So let's say you decide to go out for a ride in the country but feel the range just won't cut it, you just plug in your top box battery pack which would probably give you an extra 40/60 miles, and for those extra long journeys slap on a tank bag that has been adapted into a battery bag. If you have the batteries lying around anyway that is. Perhaps that original Chinese battery I don't recall if you made use of it in some way. But keep it as a plug in extra range battery that you can simply slot on the back of your bike as a top box.
Faster charging only degrades the battery if you're exceeding battery specs. You're literally using Tesla batteries that are rated for it and will handle it without a problem, the only thing you need to keep an eye on is battery temp.
How many amp hours is the battery? Most Li-ion batteries are rated for 1C charge meaning 1 hour charge time (plus the extra minutes when the battery is nearing the full capacity and current is ramping down) from 0 to 100%. This is in ideal conditions so a max charge rate of 0.5 C is a good rule of thumb. This means that if your battery is a 100 Ah you can safely charge it with a 50 A charger from the battery perspective. Of course you would have to make sure the wiring, BMS and possible fuses are rated for and can tolerate that amount of current but one thing is for sure. 21 hour full charge is unnecessary slow.
Simon Andersen the main thing is the cost of the charger. He doesn’t need it to be faster, and a 100 amp charger runs at least 500 dollars, so he hasn’t had a reason, I’d wager
Is the bike Bluetooth connected. If so maybe set up a program that would give you a reserve function like on a gas bike. You know just enough to get you somewhere other then on the side of the road. Also have it with a speed limiter so you don't damage the batteries.
This kind of project is fantastic as a source of real information. But to me it is clear you can’t make much of an e-motorcycle with current tech. The huge bottleneck is the battery. The huge problem is the aerodynamic inefficiency of a motorcycle versus a sleek car. Every test of every emoto shows that as you drift above 60-70 mph, the watt hours per mile soar to over 100. How many kwh can you put on a bike frame. The Harley’s size helps, but it’s not enough. You say you have a useable 10 kwh, but at 120 watt hours per mile, that’s like 80 miles. This problem is made much worse because around here the speed limit on the interstate is 80. People go 85. You need a big bike, a big motor, and a lot of battery. The CYC X-1 Pro is an interesting motor. They claim the 8 pound motor is 5 kw. It’s a mid mount. Maybe you could find a light motorcycle frame and adapt it. It would just be a commuter bike.You could look at Hall sensor watt meters and watt hour meters. See what you use, keep track of what is in the battery. No wiring for the readings.
Remember electrical devices have a "happy power zone", as the voltage drops the current draw increases to maintain that "power zone", this will help you account for the faster drop rate at the lower end of your voltage scale.......voltage up, current down; voltage down, current up....
Hi so I set the minimum voltage to 48V for me because that's just the pike minimum voltage that can only be reached when accelerating and the battery can withstand it , most have 2.5V in the current state and I am sure that the maximum discharge value is around 2.3V, therefore a 20s battery 46V and in the current state 50V is okay as an absolute minimum and as far as you drive the battery anyway not down it is about the problem of switching off what you can prevent! The next problem, however, is the BMS, which switches off much too early in a standard version, which is why I can only recommend a programmable BMS where you can adjust these values and I have now coped very well with it for 1 year without problems 😉 and I have almost everyone Fully charged every day with a 10A charger, the battery is fully charged in 3.5 hours 😎 even after 1.5 hours it is 80% that will automatically lower the battery so it is absolutely safe to charge with it 😉😎 absolutely save. Achso and where you can still extend the battery discharge voltage is to set the battery current to 62-63V and drive the controller to 75-80%, which also significantly lowers the battery temperature! 🙋♂️ And you don't lose much power, at least it helps it is easier for me to drive because otherwise I only drive in a wheelie when accelerating 😅😁
you could do solar charger by installing one solar charger while you ride i don't have lot of money to throw around i would not mind have a e motor cycle but what i am gone to do if have one e motor cycle solar charger fore back power supplies and charge the bike on the road at the same time so you have more time ride then power down just think about it you set speed to 175 mph and yes you need your breaks redone thumb up on your video
The distance kills my want for a e bike. For me the the next town over is like 30 miles for anything other than farm stores and grocery stores I'd like to be able to hit the road and got 300 miles if I want. I love this series and I love the concept. Personally they just are not fast enough or go far enough. Maybe hybrid bike will be a thing one day.
Enjoying what your doing , backing music choice not my flavour but hey world world be boring without the choice, just maybey knock 10-15% off the volume.
Never fit a voltage readout. My mate has one on his ebike and he just frets all day as his volts drop. I ride till it conks and carry a get me home 5ah batt in my backpack.
Great job on the bike series. Will be watching Great videos. It's to bad you cannot adjust the battery while on the road. It wouldn't leave you stranded again.
Man I wish I had tools and a good brain because I have 2500.00 saved up, took me two years. I need a ebike, probably Juiced Hyperscorpion. I can't obtain a driver's license, long story, so I need peddles on it to be legal. With your brains I could build a better electric bike, although juiced Hyperscorpion looks like a moped, which I like.
What is the company you bought it from? I'm looking on Alibaba and I'm really nervous to spend hundreds of dollars on something I might never receive or that may come with issues and regret. So I'm looking for people who have had success buying from China who are willing to share there information with us. Thank u for making this video!!

Def low voltage cut. Check your cells discharge curve. For example 84-74v could be around 75% of power even though min is 60v. Great work
So glad to see you back. Thanks Inja.

At full throttle that range is up there with the best, although your home build battery is probably more than twice the size of a stock electric bike battery. My Evo is 40ah but at full throttle I can expect 25-30 miles range. In the City nearer to 50 miles.
Been waiting for this video to come out thank you for all the content you put out keep up the great work 👌
My pleasure 🙌🏽
Good work bro.
Your hard work and results motivates me lot.. Nice to see your everyday progress..
Keep it up. 🙂👍🏽
Maybe a capacitor bank would help with the voltage sag?
OooooOooo
@@TheInja just remember it has to be parallel
I don't think the voltage sag is hurting him. The motor already gets plenty of power for it's size. Maybe it would give a bit more power to the motor right off the line? Improve the 0-30 time? It's possible I guess.
Stop buying anything from China
@@johnrice6670 Who are you to tell people what to do?
I have two questions.
1) re Brakes. What replacement pads/rotors would you need to use?
2) how much mileage did you get, once you hit 65v?
Thanks mate, these are great videos, you should be rightly chuffed with what you've built!
Regenerative braking has to do with the hub motor switching between using battery power to accelerate and using the vehicle's momentum at speed to create power while decelerating to recharge the battery like an alternator would
Brakes are direct replacement with 2008-2012 Ninja 250. So that's easy and cheap!
Only like 4-5 miles before I was stranded after the first cutoff
If you want to keep the battery healty for as long as possible, if you do not normally need the full range. Consider only charging it to 80 or 70%. It is not only at close to empty that these batteries take extra wear from the charging cycles.
As a reference and practical test you could try AccuBattery app to monitor the health of the battery in your phone.
Aerodynamic resistance, being dominant from 30mph upwards, rises 4 times by speed doubling, meaning, 60 miles at 60mph is 240 miles at 30mph!!! Almost... And additionaly, not steep voltage drop by city-driving.
Use your regenerative breaking more will help with getting more distance... love watching
In the city I can, country I can't
This is really impressive good job inja great work 💪👍
I really enjoyed this build. The two of yous really make me want to build my own , but the bike I'm looking at is an E Boom . they are the electric version of a Grom clone.
Maybe as your next build you do an Electric Grom clone . They only go 50 mph / 50 miles . see if you could increase the top speed while trying to double it's range.
You should try to duct some air over the controller from the front of bike or through tank then you can up your regen substantially. Great build
Flawless Victory
I bought the Voltage meter/USB charger combo for 89cents shipped from China, it has shown to be a more reliable design + You can charge through USB.
Great ! Just great ! Suits me just fine for the mileage I do. Regards. Trinidad & Tobago.
Lithium batteries... thats how they roll, hold on strong to the very end... then drop like a rock.
And a 1c charge rate (even 1/2C) will dramatically reduce your charge time if you can pull the amps and wont hurt your battery life. I have been charging lithium ions and li-poly batteries at 1c for over a decade. I dont push them harder than that though.
Not bad awesome build bro can’t wait to see what’s next
Your mind bout to explode. New series starting in the next couple weeks and it's HUGE
Im curious as to how much more range you would get at a more agressive regenerative brake setting. Like maby do a test at 50% then another at 100%.
Awesome project! Ive been following it from the beginning. I love your videos man keep it up!
Regen on a light motorcycle doesn't really do that much. Likely a few mile improvement, like 5 maybe.
I don't know much about this things but I've had one as well, and I gotta tell you that you shouldn't leave them unused for awhile, when you don't have plans to go out just have the battery drain a bit and charge it again or else the battery life will completely just go down and down till it dies like what happened to mine
For sure
What a beautiful machine 😍
I"ve been getting 150 mile range in town with these bikes.
According to battery University, longer charges do stress more the battery than fast charging.
The costant voltage, the heat produced by it has a negative effect on batteries.
No, it's the other way around. Faster charging requires higher amperage. This stresses the cells more and increases the temperatures. Slower, lower amperage charging gives less heat and longer battery life. The Constant Voltage part of the cell charge cycle (at the end) does not produce much heat.
83 miles, wow...thats pretty decent for a "own build" electric motorcycle! - If you now cut off these "0 to 60 in 2.7 seconds" to minimize the Amps (or the power draw peak) going from battery to the Motor to have longer range, could you test that? so then the bike would accelerate in 6 secs to 60 or something similar, but you didn´t have the power drop so much faster......is that an idea?
I see you have quite a collection of motorcycle now.
Could you please do a garage update on all the motorcycle 😁
For sure, coming soon!
83 miles/133km. That was really a good range. In my country, 50-60km range on an electric bike is the best you can have. We don't have lithium batteries because it is so hard to find a legitimate supplier here and it costs too much. We only have lead acid batteries and it weighs a ton. 40km on my bike is good and I'm happy with it but 133km? I would love that bike more than I do with my girlfriend.
Hahaha! (Hope she doesn't see this)
I solved the take off speed of my direct drive rear hub with a 750w front geared befang hub motor which is faster off the start helping rear motor to get to speed.
I'm so tempted to buy the 8000 watt version from China but after watching your posts I'm reluctant, great videos and brilliant job on your bike
Definitely don't. They won't send you the one you ordered. They will fudge some components to cut costs.
@@TheInja il take your advice ,cheers
Buy the cheaper version and build it up like the inja
Or just convert a gas bike with a bad engine.
Great video as always keep up the good work tell lord curt he’s awesome !!!
Sweet range
Love this story. Keep up the awesome vids
It's a pity that you don't have some sort of onboard Solar panel to extend the range or try to convert the kinetic energy into potential energy Via a scaled up alternator etc l
This is why internal combustion will never die.
California gauge of stormy and windy is different than where I live LOL. Great project. What was the final outcome of this project?
This is really kool. My dad and I build ebikes and so far the fastest we built is my dad 5K and we with the set up we hit over 70mph it’s capable of higher speed but just feels so scary
Cheers I enjoyed that, Being a shift worker could you do some city/suburb night riding, would like to see how the volts handle the lights being on, short rides 15 minute and a 30min ride would be great length and as I see it night riding/driving has less traffic so it should be fairly smooth on the battery, but with the lights on will it make much or any difference at all, Cheers again Ride Safe.
Lights were on, and I rode it for almost 3 hours on this one charge
Making it look like you know what you're doing 🤣👊🏻
Lol what was your last build
@@TheInja a bit more mainstream, 954 fireblade powered kitcar.
Nothing beats dinosaur juice powered engines! Instant recharge by simply filling your tank, no waiting 21 hours to proceed on your journey.
When did he get it street legal and register it? I didn't see anything about it in the series 🤷🏻♂️.
I like the way you test. Just drive directly away from home until the battery dies. Then call for help.
That range is pretty impressive. If you stuck to city riding you would probably get a lot more out of it. Shame the bike takes so long to charge though surely you can upgrade the charger to something a little better as waiting that long for it to charge certainly affects the usability of the bike. The guy who helped build the battery would probably know of a safe faster charger to use.
I only anticipate charging at night, so I'll have plenty for the next ride. Never will run it all the way dead though 😆
crazy how much you changed in the time you got this bike i been building my own little 350w electric scooters but i got my big ebike with a 55ah 16s 2p chevy volt battery running 6kw i get up to 85 mph but its getting dismantled because had the bike for almost 7 years now 3 motor swap 5 controllers and im afraid the aluminum frame may start to develop cracks i have for sure over 100k miles on it its been my daily driver for that many years i had 4 different batteries first was a 36v lifepo4 2nd 36v 14ah lithium 3 was a 72v 20ah and the 4th is the one im using 55ah 16s 2p wish i could get one of these i saw a motorycle like yours for 2300 in curacao but only says 30mph 30ah 72v battery lithium display is different and is set to mph so i may get it its a local store
Hi, good range. Probably next project , you install crank set ?😀
Well done bro! Thanks for the video
For sure, thanks for watching ☕
Here's a suggestion as you like to tinker with these things, well you kinda got dropped in the deep end but never mind you learned a lot.
Anyway to the suggestion, why not fit a top box on the back, and use it as a country ride battery pack, also a tank bag could be adapted for those country rides as well.
So let's say you decide to go out for a ride in the country but feel the range just won't cut it, you just plug in your top box battery pack which would probably give you an extra 40/60 miles, and for those extra long journeys slap on a tank bag that has been adapted into a battery bag.
If you have the batteries lying around anyway that is.
Perhaps that original Chinese battery I don't recall if you made use of it in some way.
But keep it as a plug in extra range battery that you can simply slot on the back of your bike as a top box.
Faster charging only degrades the battery if you're exceeding battery specs. You're literally using Tesla batteries that are rated for it and will handle it without a problem, the only thing you need to keep an eye on is battery temp.
I’ve had one of those battery volt meters you have and it got wet then broke. I suggest getting a waterproof one
How many amp hours is the battery? Most Li-ion batteries are rated for 1C charge meaning 1 hour charge time (plus the extra minutes when the battery is nearing the full capacity and current is ramping down) from 0 to 100%. This is in ideal conditions so a max charge rate of 0.5 C is a good rule of thumb. This means that if your battery is a 100 Ah you can safely charge it with a 50 A charger from the battery perspective. Of course you would have to make sure the wiring, BMS and possible fuses are rated for and can tolerate that amount of current but one thing is for sure. 21 hour full charge is unnecessary slow.
Simon Andersen the main thing is the cost of the charger. He doesn’t need it to be faster, and a 100 amp charger runs at least 500 dollars, so he hasn’t had a reason, I’d wager
Is the bike Bluetooth connected. If so maybe set up a program that would give you a reserve function like on a gas bike. You know just enough to get you somewhere other then on the side of the road.
Also have it with a speed limiter so you don't damage the batteries.
Not a bad idea!
This kind of project is fantastic as a source of real information. But to me it is clear you can’t make much of an e-motorcycle with current tech. The huge bottleneck is the battery. The huge problem is the aerodynamic inefficiency of a motorcycle versus a sleek car. Every test of every emoto shows that as you drift above 60-70 mph, the watt hours per mile soar to over 100. How many kwh can you put on a bike frame. The Harley’s size helps, but it’s not enough. You say you have a useable 10 kwh, but at 120 watt hours per mile, that’s like 80 miles. This problem is made much worse because around here the speed limit on the interstate is 80. People go 85. You need a big bike, a big motor, and a lot of battery. The CYC X-1 Pro is an interesting motor. They claim the 8 pound motor is 5 kw. It’s a mid mount. Maybe you could find a light motorcycle frame and adapt it. It would just be a commuter bike.You could look at Hall sensor watt meters and watt hour meters. See what you use, keep track of what is in the battery. No wiring for the readings.
Would be interesting to see a dyno test
Are electric bikes automatics? Great vlogs btw, love your presentation skills.
Remember electrical devices have a "happy power zone", as the voltage drops the current draw increases to maintain that "power zone", this will help you account for the faster drop rate at the lower end of your voltage scale.......voltage up, current down; voltage down, current up....
Hi so I set the minimum voltage to 48V for me because that's just the pike minimum voltage that can only be reached when accelerating and the battery can withstand it , most have 2.5V in the current state and I am sure that the maximum discharge value is around 2.3V, therefore a 20s battery 46V and in the current state 50V is okay as an absolute minimum and as far as you drive the battery anyway not down it is about the problem of switching off what you can prevent! The next problem, however, is the BMS, which switches off much too early in a standard version, which is why I can only recommend a programmable BMS where you can adjust these values and I have now coped very well with it for 1 year without problems 😉 and I have almost everyone Fully charged every day with a 10A charger, the battery is fully charged in 3.5 hours 😎 even after 1.5 hours it is 80% that will automatically lower the battery so it is absolutely safe to charge with it 😉😎 absolutely save. Achso and where you can still extend the battery discharge voltage is to set the battery current to 62-63V and drive the controller to 75-80%, which also significantly lowers the battery temperature! 🙋♂️ And you don't lose much power, at least it helps it is easier for me to drive because otherwise I only drive in a wheelie when accelerating 😅😁
you could do solar charger by installing one solar charger while you ride i don't have lot of money to throw around i would not mind have a e motor cycle but what i am gone to do if have one e motor cycle solar charger fore back power supplies and charge the bike on the road at the same time so you have more time ride then power down just think about it you set speed to 175 mph and yes you need your breaks redone thumb up on your video
The distance kills my want for a e bike. For me the the next town over is like 30 miles for anything other than farm stores and grocery stores I'd like to be able to hit the road and got 300 miles if I want. I love this series and I love the concept. Personally they just are not fast enough or go far enough. Maybe hybrid bike will be a thing one day.
I agree!
Hey man thanks for making these videos. I hope to keep seeing awesome stuff even though I dont think you make a living off of them.
Enjoying what your doing , backing music choice not my flavour but hey world world be boring without the choice, just maybey knock 10-15% off the volume.
Never fit a voltage readout.
My mate has one on his ebike and he just frets all day as his volts drop.
I ride till it conks and carry a get me home 5ah batt in my backpack.
put another hub motor in the front :P 2 wheel drive
Very serial take off👍
Inja have you ever thought of looking at solar panels to help keep the battery
Great job on the bike series. Will be watching Great videos. It's to bad you cannot adjust the battery while on the road. It wouldn't leave you stranded again.
if you use a 84v 15 amps charger you should have a 3 hours charge 0 to 100 and still 2000 cycles to 80% for the battery longevity
Damn Inja you growing Fast As Hell
😏
Pumped 💯
Man I wish I had tools and a good brain because I have 2500.00 saved up, took me two years. I need a ebike, probably Juiced Hyperscorpion. I can't obtain a driver's license, long story, so I need peddles on it to be legal. With your brains I could build a better electric bike, although juiced Hyperscorpion looks like a moped, which I like.
Definitely close to the current benchmark motorcycle the zero sr.not bad for a hub motor and diy battery
Zero sr is 70 hp and 116 lb ft of torque as well as 223 miles city and 112 miles highway range.
So Solid! I'm Amped! Salute
What is the company you bought it from? I'm looking on Alibaba and I'm really nervous to spend hundreds of dollars on something I might never receive or that may come with issues and regret. So I'm looking for people who have had success buying from China who are willing to share there information with us.
Thank u for making this video!!
Fast chargers DO NOT reduce battery "significantly". Yes, they do reduce life, but not by much.
did you ever tried to get tags for your electric bike ? to make it street legal
What's the update on this bike? How are you using the bike so far?
What your feedback after months of using this?
