This is unironically the best build I have seen yet. It seems more accessible than all the other builds. It is high performance while having a good range and keeping a cool conventional look. Great work!
I love that you did this in your backyard, yet major manufacturers can't seem to get above 75-100 miles of range. Well done sir, this is the bike we need! 👌
The best realistic electric bike build. Good idea to use shaft, my 220Kg (480 lbs) Zero SFF used hard hammers the drive belt with its 14 kWh battery / 110 HP motor. My guess is your bigger motor, shaft drive and heavier battery equates to 550 lbs and as you say riding an electric gives an uparaled connection to the biking experience. I ride other gas bikes but ill take that linier glitch free. smooth, throttle response over noise anytime. Thank you for taking time to show how its done, brilliant practical build.
VERY impressive. I like the fact that you took into account motorcycle balance. Also noted that you're thinking safety as well. The use of LFP type batteries makes so much sense in a motorcycle application- you nailed it. Thanks for making this video and thank you for including all the links. I got a lot of 'homework' to do but I'm almost ready to pull the trigger. Your vid I think pushed me further towards the edge. Ride safe sir.

@@highervoltage5430 Hi Alex, l really njoy ur channel, thanks. With ur electric Sabre road bike, being able to centralise the motors mass, could you use a power divider/drop box l've heard them called? Could give it a little extra mechanical/gear noise. Maybe a redesign, or something for the next one.....😊 Just a thought, cya.
It's my dream to build my own electric motorcycle. It's awesome that people like you are building these machines themselves and achieving such ridiculous numbers! I'd be glad if my future build even had a 3000 Watt motor in it. Thanks for sharing your build! Didn't know those batteries. They seem like a good option for EVs. Subscribed! Hope to see more EV related content or more insight into this beast!
naaaaaaaaah dont fret its everyones dream here... you can start with this and save a lot of weight and bulk hassle for the motor www.ebay.com/itm/High-Power-8KW-72V-Brushless-Electric-Motorcycle-Scooter-Hub-Motor-55-74mph-NEW/124100643651?hash=item1ce4f98b43:g:e6MAAOSw5K5dFnNh you can pay me later for the great advice! i only accept paypal by the way.. ;)
This is by far the best build I have ever seen. If this was manufactured, I would buy it in a heartbeat. Fantastic engineering! Fantastic looks! Fantastic performance! Absolutely great job!
Impresive build, Impresive how in so litle time explains so many things in a way someone like me with 0 knowledge abaud electric can understend. Sire your Moto and vidio looks to me like the work of a great Master.
It feels like a hack job to me honestly. I cannot make things look good to save my life. I just make them work. THe truth is electric vehicles are pretty simple compared to their gasoline counterparts.
@@highlanderfreelancer4553 - The bike weighs in at ~560lbs which is about 40 lbs heavier than the bike I started with. It is definitely top-heavy, but once you get going you don't notice it. It is such a difference and peaceful experience riding an electric bike that it is hard to describe.
This is definitely the best tutorial on RU-vid about building an electric motorcycle. Key points including the choice of battery, the mechanism of the electric motor, the weight distribution, and etc. are all very clear. I particularly like how you orally presented the math of power.
I love motorcycles but hate electrics but your crystal clear presentation and logic of design made this a pleasure to watch and learn from. Thankyou for uploading this!
I learned so much. I want rebuild my own, so this has been super helpful to understand why you choice the parts and the others options available with their trade offs🙏🏼😄
Higher Voltage, I like your honesty and accuracy to detail. All of the other motorcycle were very expensive and did not give out the performance that your bike does. Thanks, very much for your showing us the guts of the bike, and why!! *heart *heart *heart! (They don't have the red heart emote I want.)
This was by far the most comprehensive and informative video for electric motorcycle conversions I have seen. Your explanations have helped me out immensely. I will definitely be contacting you about my build.
Wow... Just wow.. This is the most informative video I have ever seen. So much important info in so short time, and so very well explained. I do know alot, but after seeing your video, I know alot more now :) After 10 seconds it was impossible to stop watching, and the build was incredible good work. Thanks for sharing.
You did in hell of a good job, Young Man. Well done. You know your Electrics well, I am/was a Technical Design Engineer. The Motor/Batteries off set, if minor, is a niggle that must be solved. Have you considered a Fluid transmission ? A pump off the motor via two flexible pipes to a drive at the rear wheel, shaft OR chain type ?. This would allow the motor to be situated ANYWHERE in the Bike, below OR above the batteries, depending on what was heavier for low Centre of Gravity. .
There are a few issues with a hydraulic system like that: complexity, real-estate, and loss. The off-set battery isn't noticeable and I do intend to one day cover it all up with a symmetrical fairing if I ever figure out how to do fiberglass work. The only issue I currently have is that I wish I could gear it shorter for even more acceleration... because 0-100 in 5 seconds could still be faster ;)
@@highervoltage5430 Hydraulics ARE more complicated than a direct shaft drive, no doubt as nothing is simpler, and a fairing WILL cover a multitude of unsymmetrical sins. (Check any stripped touring Bike.) What do you mean by real estate ? An unfamiliar term to me here in the UK in relation to Bikes. As you are still looking for gearing changes, perhaps a gearbox that may also off set the drive line ? Just because an electric vehicle doesn't critically NEED a gear box, that doesn't mean it won't BENEFIT from one. Alternatively BMW have different ratios in their final drives. (I had a R45 which was different from the identical exterior R65's.) Check if others may fit in yours. A fellow here in the UK converted a car, retaining the box, and it gave him a series of performance options. Even a REVERSE. Your Bike won't be light to paddle backwards up a slope or away from a kerb. Note. My suggestions are not meant for your current Bike, but looking forward to a Mark 2. (I have been considering building myself a 2WD Electric Bike with radical new frame geometry for a while now. 50+ years of Biking experience and ownership/maintainence.) Finally, You STILL did a hell of a good job. . .
I think you missed the "better known as iBcrazy" part😂😂. Excellent videos, I'm glad to meet your channel. Really enjoyed your FPV tutorials in the past and I'm now enjoying your ebike ones!!
You have done an excellent job in presenting your expertise. I hope you don't get burnt out with not so nice people. Your knowledge is obvious and the next one you build will be far better than the first one. You are on the leading edge of the future. You might consider selling a conversion kit to profit from your hard work. What is a good database for buying the motor and controllers? Thanks and job well done.
I'm not sure what is a good database. EV information is so scattered which is why I made this video. I wanted a place where people could get started and know what they need to build their own (which is why there are links in the video description). Although I have no intention on making money from this work (I do it all for fun), I said the same thing about developing antennas for drones and now I run a business doing precisely that.
Well done Alex brilliant stuff mate! Its unbelievable both of us decided to build an electric drive on a Honda though mine is a classic from the late 80's. She has done around 6K clicks and handles so well.😎
Lithium for the win when looking for range and instant power! The range you’re getting sounds wild! Thumbs up 👍🏼 on that 88 kw motor, that thing looks so beefy 🥩!!!!
@@p3dtesla118 - I am not interested in selling it, but you are free to come ride it. I am in Amherst, Va. If you are in town, feel free to reach out. I am always happy to let other riders try it. I publish these videos so that people can build their own.
I highly doubt the Sabre 750 was less than 500lbs off the showroom floor. Bikes did not really get below the 500lb mark on 750cc’s. I doubt you added weight and if so, minimal. UJM’s are great daily bikes. My last bike I owned ( last year) was a Honda Valkyrie. 700lb bike. I bet it would make a super sweet eConversion. I have built 2 electric bicycles and I LOVED the experience A-Z, a conversion like this is a MUST DO for me. I love it! Fantastic Job!! Thanks for sharing! Merry Christmas 🎄
Another good reason to make sure the suspension matches the new weight is if the rear is too soft it can become squirrely and cause you to crash. This is why bikes have adjustable pre-load on their shocks in from factory.
Bike seems cool for sure for one I'd change to the graphene battey's they hold 2x more charge than lithium so means you can reduce weight. The battery's weight can be reduced in 1/2 or just have x2 more range, and if they do catch fire you can put it out with normal fire extinguisher.
Dude!! You are definitely SICK. That has got to be the smoothest upgrade to a bike I have ever seen. I have a '83 and an '84 V65 and they are pretty wicked pure stock. but this totally takes the cake. Those early 80's v4s were the "Harley Killers" (FYI). That is why your frame only had a 700cc motor. The new Harley electric is $38,880 so I would think $11,400 is a steal. And -- you have the only 1985 E-Saber known to man. Very, very, very, very impressive. I presume the regenerative braking only applies to the rear. Does that have any meaningful benefit other than extending the life of your shoes?
THANK YOU....i've been trying to remember where i knew him from...Yeah..it's been some years since he told me how to do antennas, i almost forgot... Awesome.
Cool tech man. I been using lfp batterys in my bike and I love them. No one else gets it. I got ebike whit throtle about 1.5kw power. Its really no bicycle. I made 2 12s2p 37v 13ah batterys out of high performance 6c rated cells. So 26ah or 1kwh combinated. Performance is really good. 24mph tops, but that is whit cracy acceleration. Uphills don't matter much at all. I don't know the range becouse I never run out of juice and I can charge quikly, no point to test that. Ideal for electric vehicles :)
Awesome! What about sealing everything to avoid short circuits? I have a 1kw qs hub motor with 48v 20ah battery on a mtb hardtail and I plan to swap the frame with a full suspension, maybe a dirt bike, while also maintaining the pedals to be a legal bike. The regen brake is nice knowing that you can harvest some of that energy back :)
i wish i used that motor insted of the netgain warp -9 brushed. although i am extremely happy with my performance package. the controller i use is the zilla 2000 amp at 200 volt 0to 60 3.2 sec first run
Awesome job, and good video! Shaft drive has a lot of advantages, but a chain drive bike would put the motor in a much more central position. Although your motor might be too long/big to make that feasible. I have a 2016 Zero SR, which I love, but your bike has more range and higher top speed. I also have a 2006 Hyosung GT650S, which is a lot of fun but is absolutely Neanderthal. The engine is strong but it's a V-twin and it's really not happy in city traffic. I was going to sell the Hyosung, but maybe I'll convert it instead. Electric drive in that chassis would be prodigious fun, especially if I could get more range than the Zero.
I hate electric trucks so much but electric bikes have always been really interesting to me. They just make more sense to be electric since they can't tow or haul anything like a truck can. I hope to do a similar build in the future after I've gotten a good bike to work with.
This is a fantastic build. Any way you could document a parts list, along with any build challenges you overcame during assembly? You should consider documenting this and selling it as an E-book. I would buy it! I need me one of these!
I am bulding another one. THis time a dual sport motorcycle. I have most of the parts and I will begin building shortly. Hopefully I can shut the birds up so the sound doesn't suck.
Thanks for the info! Any chance you could share some resources on how you figured out how many batteries you needed? From an AHr perspective I can't figure out how much is enough.
I'm extremely interested in doing almost exactly what you've done here. I'm going with a 12KW hub motor and hopefully the 30 of those LiFePO4/120 Ampere-hour cells in series. What did you use to reference while building the battery pack, or did you just know what to do?
Electric motor too produce more power as the engine speed up. Torque x speed = power for ICE as well as electric motor. the torque curve is just different. I think what you meant is not power but TORQUE increase as engine rpm build up on ICE. The best way to explain is that compare to ICE, the electric can have full torque at 0 rpm while ICE dont. Nice video and project btw!
PMSM is more efficient than BLDC, with all other features. also shifting to a axial flux motor will be more power dense and produce more torque by nature.
Your performance figure and range are similar to my Honda VFR1200x Crossrunner. Pros: my VFR costs about £25 UK to fill not $2 US, and it does about the same milage 160 - 200 on a tank. And accelerates about as hard. 60 comes up in just under 4 seconds. Cons, Petrol doesn't take 6 hours to fill. I wouldn't swap with you but if you gave it to me I'd be happy to run both and ride the best one depending on what I planed to do. Nice video
Just for your information, the discharge rate of lithium ion phosphate is lower than many other lithium cells. Lithium ion cells can do up to 10c, and some lithium polymer can do 60c +
Popped up in my recommended... I was sure I knew the face and voice but threw me as it wasn't the content or channel I was expecting... Great content and very informative as expected from you! 👌
Very informative. My only gripe is that your speaking is significantly quieter than your music and final sound effect. Evening those sound levels out will give your videos a bit more polish. Going to check out your other videos, hopefully you'll have another subscriber.
You said 36 cells in series, @ 3.2V per cell. Does this mean your battery pack produces 115V with a total capacity of 120Ah? The high voltage makes sense for how you're getting the big performance numbers out of that motor, but how did you estimate your range off of that capacity? Or did you just....build it and find out?
Try the electromagnetic piston/head motor. Big newtons strait to the trany. 200Nm, 400Nm, 600Nm. Look up the value of a Nm to Hp conversion then torque. You will see your motor head evolve
You use the stator on the side of a PLA 3D printed block to in time deliver the variable 2v~24v speed regulator. Thus the electormagnetic head engages the piston magnet to repel creating Nm's left to your imagining. P.s.zoom zoom vroom vroom We win races.
