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.
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!
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!
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.
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.
This guy is awesome. Love the bike! Nice job!
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!
love it! thank you for giving the details of the build
Wow, awesome bike and full of features on electronics side.
extremely impressive sir... thanks for showing
been looking for a frame for my motorcycle project. I think I've found it. :) thanks man.
That's one powerful little beast!
This is awesome you are a talented man.
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
That's one really classy bike you've built.
I wish I had 1/10 of the knowledge in electronics that you have.1
Wow that looks fun to ride!
love it shes a bloody ripper mate well done
DANG!! You da man, built your own controller. I bow down =).
It is work of art. Good job.
.
Great product- worked perfectly, no issues.
superb work man
Adamlar evin garajında ne güzel şeyler yapıyo keşke bizimde imkanımız olsa böyle
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 >_>
Great work! Love to see the firmware on that controller!
watched this with the biggest smile in my face.
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 :)
:O wonderfull electronic wisardry sir , awesome bike!!
how do you not have more views? brilliant.
nice work once again!
Nice job on all the work done. The seat my be uncomfortable, but the whole bike looks great.
Love it building my 3rd this week
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?
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!!!!
Wow you are very smart.
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 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!
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.
nice :D thats inspiring im doing a escooter project, amazing torq of the motor in your ev :)
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.
Wow, quite the bike!
Nice bike. I have a Stingray that I was considering to convert to electric just for fun.
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 ….
Jimminey flppin Xmas. Fine job. I have a Harbor Freight 212cc motor on mine. 😂😎
I dig your bike . . .
Very very interesting. Thanks for sharing. ;-)
that's really cool!!
Looks like I need to build a bad ass electric bike.
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!
Got the same bike might try this :D
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.
This is awesome.
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?
And you have a B&D 24V cordless lawnmower too cool.
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.
HI, can you please share a bit more a bout the BMS and motor controller if possible.
Thanks
Do you have a schematic you are willing to share?
Of course your Electrical Engineering is WAY BEYOND most anybody on RUclips so if you had a web page or something it would be FANTASTIC! WOW!
Very cool👌🏽
Impressive, as always!
Is it a simple PWM DC controller?
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!
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
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
You said that a pot activates the regen, implying variable regen? That's awesome!
Yes, fully proportional regen control.
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
whats the range on that thing... and hats off to you man.... i am always amazed with your talent for design.
yeah like this cycle looks good like
Well, he knows what he's doing.
I want one now
Don't see many bronys that do electronics, cool!
Way cool=awesome!!!!
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?
i have a old dirt bike with bad gas motor i think i want to convert it to electric if i can put regen braking on it that would be cool
Yeah regen is entirely possible with off-the-shelf controllers.
Wow Just Wow !!!!
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?
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.
Have you thought of using the sprocket as a disc brake?
wicked. I'd worry about the chain jamming up and crashing.
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
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?
Maybe I missed it, did you mention the range of this e-bike? Great video btw :)
For a possible new motor, could you try a PERM 132? (Or a PERM 80)
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?
With that much torque does it eats up the spocket tooth?
I guess you could make a smaller sprocket on the rear wheel for higher top speed while taking advantage of all the excess torque.
I wish i had the resources to make an electric bike, but why would i when i have a 80cc chainsaw engine from 1976 almost ready to back on my old bike. ;)
How far do you get with this before you need to recharge the battery's?
Respect
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 app you used for aceelometer in Your phone ?
12:00: What about the hub brakes?
wow! amazing bike (",) tony starks :)
INTERESSANTE A ENGENHARIA DESSE MOTOR VC FEZ OU E DE QUAL MARCA ????
That must have been hundreads of hours to built!
Thumbs up :)
Also I was thinking, face off the rear sprocket and use it as a disc brake haha
Gotta love how that's considered a bicycle. Here, anything over 250w is an "electric moped" :(
