Specs:
Briggs and Stratton Etek electric motor
44.4V 15Ah LiPo battery
300A motor controller
45km/h top speed
Acceleration 0.5G "Limited by flipping over" - Věda a technologie
I'm just learning about circuitry and electric motors and actually was wanting to build an e bike from a stingray that originally was my brothers and has been sitting under a porch for a decade. Your post is very informative and is explained well. Thanks
Thanks for taking the time to go over your build. I learned a lot watching this.
Thank you for mentioning the metric system while giving data and really, kudos for this amazing work!
I´m a big friend of selfmade electric vehicles.
Your Bike is a big inspiration for me! Thank you.
Some years ago i saw the "eRockit" Bike and was blown away how cool this thing was (and even is).
But the whole thing is even cooler when it looks selfmade with brain and love!
Sorry for my bad english. Keep on exploring, explaining and inventing, Daniel from Germany.
cool. its nice seeing people do their own engineering
I grew up on east 6th! Just few houses up from where your ride ended. So cool to see the old hood!
This guy is awesome. Love the bike! Nice job!
Truly a masterwork. You probly have the equivalent of a masters of engineering in the work of several disiplines. I knew it was possible, you make it real.
love it! thank you for giving the details of the build
Absolutely splendid!
Well done indeed.
I am starting on a project like this, but it will never be quite so powerful.
Indeed, if I can deliver 1 to 2 HP to the road, I will be mighty pleased.
Keep up the good work.
Wow, awesome bike and full of features on electronics side.
The motor is beautiful. My 1Hp when double voltage would cook even with 1/3rd the weight on a run like that . I'd like to see the BMS schematic and software but only for night reading purposes albeit incomplete or messy. I too built my first one around the same time with homemade controller also using pic16 & IRF1404(5). That is truly a fun looking machine!
extremely impressive sir... thanks for showing
That's one powerful little beast!
Wow that looks fun to ride!
been looking for a frame for my motorcycle project. I think I've found it. :) thanks man.
Great product- worked perfectly, no issues.
love it shes a bloody ripper mate well done
DANG!! You da man, built your own controller. I bow down =).
That's one really classy bike you've built.
I wish I had 1/10 of the knowledge in electronics that you have.1
Great work! Love to see the firmware on that controller!
This is awesome you are a talented man.
how do you not have more views? brilliant.
:O wonderfull electronic wisardry sir , awesome bike!!
It is work of art. Good job.
.
Your bike is awesome and I'd like to build one myself. I'm a relative noob to electronics but I guess that's how you learn it.
Put a Bafang Midrive on your bike you ill love it
Nice project - it really moves!
Have you thought of switching the re-gen braking through a shunt resistor when the batteries are full? That way you would always have re-gen and save your brake pads!
superb work man
Very nice project. I'd love to see schematics for the BMS and motor controller. Keep up the good work on these videos :D
You all probably dont give a damn but does anyone know of a trick to log back into an Instagram account??
I was dumb lost my login password. I appreciate any help you can give me.
@Ramon Benicio instablaster :)
2 weeks ago I took delivery of my electric bike, the rules are quite diffrent in the Netherlands.
In NL this would be considered a moped and you wouldn't be able to register or insure it (witch is mandatory for mopeds to drive on public roads)
the most common electric bike in NL is the pedal assisted type, so you have to keep force on the chain or the motor will stop.
max assisted speed is 25km/h.
in the uk ebikes suck....
the electric motor shouldn’t be able to propel the bike when it’s travelling more than 15.5mph
the motor shouldn’t have a maximum power output of more than 250 watts
It must also display one item from each of the following:
the power output or manufacturer of the motor
the battery’s voltage or maximum speed of the bike
yeah`nd that be even worth like your human Rights Understanding innit ???
nice work once again!
Love it building my 3rd this week
Adamlar evin garajında ne güzel şeyler yapıyo keşke bizimde imkanımız olsa böyle
watched this with the biggest smile in my face.
Nice job on all the work done. The seat my be uncomfortable, but the whole bike looks great.
Take a look at the mars ME0909 motor, we used one for the weapon motor on our battle bot scorpios this year. Same power output as you claim here at 12hp but in a smaller lighter package.
Lol commented before you started talking about battlebots and mars themselves >_>
Wow you are very smart.
Jimminey flppin Xmas. Fine job. I have a Harbor Freight 212cc motor on mine. 😂😎
Very very interesting. Thanks for sharing. ;-)
Hey Guy , love the video .. Not to get off topic but I saw your cat, please take good care of him/her, I love the little critters and hate to see one go without ….
I'm looking into making an e-bike of my own and was wondering if you had any good resources on the battery management and motor controller. If I could do this this would be my first real project. Resources would be appreciated!
Excellent work! BTW for about $30 you can get bolt on frame attachment points to use a disc brake for that front. Of course you need to buy a new wheel with a disc brake. I'd recommend the ones with dot 3 break fluid -- super safe and the feel you get is just like a car's foot pedal only through the fingers. Any chances of sharing the 300 amp motor controller circuit?
I love it. I bet that fat rear wheel helps grab the road.
What a great day! First Applied Science and now tesla500. Dare I hope mikeselectricstuff posts something?
Impressive, as always!
Is it a simple PWM DC controller?
Yeah, I would definitely like to see the source for that bms. I did a similar thing with the ata6780 bms ic, but yours looks more fleshed out then I ever got mine.
i think you misspelled "motorcycle" in the title. hahahaha!
this thing is amazing, i really love the controller you made.
Rinoa Super-Genius hey it's the trike kid!
Rinoa Super-Genius you inspired me to buy a trike last rear but now Iam gonna build a reverse trike with something like this, fiber glass body rear suspension. Maybe take the rear off a scooter moped
Ive been thinkin, the back of a golf cart, the front of a bike, but with extended forks!!! And the ability to be pedaled!!!!
i like how soo much of your bike is custom made... ive built, and been improving my own electric bike ( and making videos of it)...... im sure it dosnt have the tourqe yours dose, but mine will wheelie a bit too, but not as well.
HI, can you please share a bit more a bout the BMS and motor controller if possible.
Thanks
Wow, quite the bike!
nice :D thats inspiring im doing a escooter project, amazing torq of the motor in your ev :)
Nice bike. I have a Stingray that I was considering to convert to electric just for fun.
Do you have a schematic you are willing to share?
Of course your Electrical Engineering is WAY BEYOND most anybody on CZcams so if you had a web page or something it would be FANTASTIC! WOW!
the modified contactor shown at 7:50 is beautiful! Thank you for sharing this video. Did you come up with that modification? Have you tested it?
Nice video. It would have been nicer if you had mentioned what range you were getting with that bike, particularly with that cool motor you're using.
Looks like I need to build a bad ass electric bike.
I like the work you have done to make your electric bike. Any chance I could connect with you to learn more about your projects?
You mentioned that when you used regenerative braking you dumped 100 amps back into the batteries. What exactly defines the maximum amount of burst current you can feed into a lipo pack exactly? Is it just the charge C rating or does it only really matter that you dont overheat the pack and or charge it at a voltage that causes some kind of breakdown internally?
Have you thought of using the sprocket as a disc brake?
that's really cool!!
Got the same bike might try this :D
I dig your bike . . .
You need a decent front brake on that thing, the combined weight of you and the conversion parts has made it too heavy to stop safely and quickly from speed, but what a nice bike, well done.
Dude!!! I suspected that you were Canadian but you practically riden past my place! I live on ginger. You should know where that is.... I'd be so cool if we meet up!
Nice build :) But is that really 12hp on the wheels? Looking at videos on electrical bicycles with standard 1500w motors (2hp) seems to have very similar power as your creation. Maybe litte less acceleration on a hub motor but they are much faster.
Maybe I missed it, did you mention the range of this e-bike? Great video btw :)
This is awesome.
whats the range on that thing... and hats off to you man.... i am always amazed with your talent for design.
And you have a B&D 24V cordless lawnmower too cool.
Wow, so much custom work! Very impressive results, of course great performance, but also great flexibility. Those little RC batteries have amazing energy density and the current makes me a little frightened. Did you consider a thermal cut-off, or did I miss it?
When you described a street legal ebike I knew you lived in Ontario, but I can't place your town.
Thanks! The batteries make me nervous too, something like 1000A short circuit current each! it's nerve wracking making those connections in that tiny box.
There is a thermistor so the BMS knows the battery temperature, yes.
I'm in Vancouver, BC actually, BC and Ontario both have similar laws I believe.
Great project! Can I get a controller like yours with regen?
For a possible new motor, could you try a PERM 132? (Or a PERM 80)
Well, he knows what he's doing.
INTERESSANTE A ENGENHARIA DESSE MOTOR VC FEZ OU E DE QUAL MARCA ????
ever think about cutting the brush's? it fakes out the arm to think its advance and you can get about 600 to 800 more RPMs
Don't see many bronys that do electronics, cool!
What app you used for aceelometer in Your phone ?
i'm a student and i cant really afford much i have a few washing machine engines and simular ones do you think it would be possible to make a safe el bike from that with just a few more components?
How far do you get with this before you need to recharge the battery's?
wow! amazing bike (",) tony starks :)
With that much torque does it eats up the spocket tooth?
I remember that motor in Robot Arena 2. There's a "Red" version but, I don't know if that's a real motor.
I'd love it if you open sourced the BMS! :D
Very cool👌🏽
Haha, i converted my hybrid bike and gave it a 44v 1000w hub motor and powered it of 4 12v UPS batteries, later i also upgraded to LIPO
I've wondered. Would it work if you put an RC motor in there? I know there are really powerful RC motors that are much much smaller than that.
Yes, I hope to do a better version of this with suspension, using two 6kW outrunner motors. Already have a prototype one I've added hall sensors to, because sensorless sucks for traction drive applications.
how about you clamp the rear sprocket, as disk breaks do? there is some space left. tho cooling and material not suited for that may not be too efficient.
What is the regenerative breaking efficiency? Is it reasonable to commute uphill in the morning and then downhill in the evening and get most of the charge back?
"Most" depending on the desired speed of course lol
Efficiency is probably about 70-80% from motor shaft to battery. Under good conditions you could probably approach turning your uphill /downhill commute into something that uses about as much energy as if it were flat.
Nice :D
how many power are this motor? 12KW 18KW? it's a really big motor :D i want to make a big ebike project .and i'm waiting your answer
wouldn't you get the same acceleration with a better top speed if you use a lower gear ratio and increase the current limit on the motor controller?
Yes, that would do exactly that. Would need to upgrade the wiring probably to handle the higher current.
Can you make a series or guides on how to do this? I wanna try it but I think I lack a bit of knowledg about the speed regulator and regen breaking
Well not this bike exactly because is quite unique and not really practical, but I meant an E Bike
There's a lot of websites to help you get going out there and even some clubs in towns all over.
SouthJerseySound There no clubs in my country unfortunatly
wicked. I'd worry about the chain jamming up and crashing.
How much would it cost to run a production of these? I live in Oxford ( uK ), You could sell thousands of these here. I'd like to order one myself.
Way cool=awesome!!!!
I want one now
12:00: What about the hub brakes?
Use the sprocket AS the brake?
You said that a pot activates the regen, implying variable regen? That's awesome!
Yes, fully proportional regen control.
What is the price of this moter
WHERE DID YOU GET THE MOTOR?
I've been having trouble finding an answer to this question I'll ask it here. I am fairly experienced with electric drive systems both AC and DC and understand how regen braking works. All of the equipment I'm familiar with usually uses lead acid batteries however so regen charging is much simpler (in my mind)
the question I guess is, How does regen work on a lithium battery which needs (this is where my knowledge is limited) a much more specific method of charging?
In this case, the BMS built in to the battery has an output that tells the motor controller to slow down or stop regen to protect the battery from damage. The battery makes all the decisions, the controller just has to obey the regen current limit request.
Thanks, I guess I'll research BMS that support regen or similar topics. Sometimes the biggest struggle is not knowing the questions to ask so thanks for pointing me in the right direction.
