Look how fast his hands move, I'm not surprised. Sometimes, you can't even see it until it just appears somewhere else. Look how fast he grabbed that throttle and fitted it 😮
@lyteyearz5810 Thanks for asking. The frame went fine, but the only motor I had available was not powerful enough. I plan on sorting it in the future, but at the moment, it's just a decoration.
I have a 1970 Sears and Roebuck mini bike did I put a 125cc that's modified on it that's a 4-speed and I've only had the balls to get it to around 60 to 65 mph. I'm worse than this guy
This strongly resembles a gas minibike I built from scratch many years ago. I used plumbing pipe for a frame and it was rather heavy. I needed to register it because of the engine size I used. I had a lot of fun with it. It hadn't occurred to me to build an electric version until seeing this. Nice work. It's strange that individual states regulate gas engine sizes for scooters and bicycle conversions but don't regulate electric motor sizes at all. I wonder why you spent the extra money on a gasketed battery box when the cable entrances aren't sealed.
His battery can do 30-35mph . ,but that range is sus! . I made a 40kw ( 40,000watts) footscooter. But it's 24s 16p monster scooter with samsung 50s . With 2 660 amp fardriver nd84530s . 7000wh
Almost dragging that rear sprocket when turning. Maybe up that tire pressure or change the tire to something with a stiffer sidewall if you can go larger. Unless it’s just the camera angle
Power is the wrong word here. Power is speed x torque. Given the size of the motor and the low speed (35mph), I'd say this is anything but powerful. To give in example, my bike is much heavier only 350w hub motor, and goes 22mph.
Yo, just a heads up.. you're limited to a maximum of 6,720 watt for a second or 2 with this setup. If you upgrade to an 18s setup, it'll output a tad over 7kw for a little while. I have the same motor as well
it will gap the electric ngl and for a third of the price, but due to my area I am team electric but no funds LMAO so im team gas mini bike plus cheaper to upgrade and I know how to fix vs electric I do not and its pricy
That power output is enough to go about 65 miles per hour so gear the thing properly and get better mileage at the same speed and also more speed when you need it.
Needs a bigger battery to sustain those speeds. Power is no problem, but ~730 Wh is not enough to do anything other than a quick lap around a parking lot with that power.
You should mass produce the kit to convert gas bikes those specs you just threw out are pretty good for speed and range add a second gear to hit 50 and I bet you would sell out
Like sure those motors consume a lot of watts. But they are tiny... A proper 7kw hub motor would do 100+Nm torque. That flipsky motor is rated for 17Nm max.... sure the gear ratio gives you some more but imo those are worthless in anything bigger than skateboards. Or really small EV's where hub motor wont provide enough torque.
Maan I got the same sprocket on my mini bike if u got that much power tho you’ll need a smaller rear sprocket because you’ll eventually hit the chain and sprocket on the ground and that’s not good 😮 awesome build I want an electric one
15/70 gear ratio for 7kw or 9.5hp and you only got 22mph??? You should be getting at least double. Try a 18/65. I have a built Briggs 5hp on a vintage mini bike with a 18/65 gear ratio it goes 65mph and it makes ~7200rpm. I usually use a formula to calculate top speed.(Rpm/ratio x Wheel D x 3.14 /12 /5280 x60) hope that helps.
That VESC tool is making crazy things happen I tell you, what a piece of software that is. You can even make single wheel boards like the Onewheel with it
Everyone says that for the watt capacity and the speed this bike needs to be registered but how are you supposed to register a bare metal bike with no vin number And of course I don't even think this comes with a title
sohe said 726 watt hour battery and a 7000 watt motor. Thats how you know something is off. That battery would have to be a lipo with at least 10S discharge rate or the battery will explode. And if the battery is 726 watt hour and the motor is 7Kw then you have only 5 minutes of ride time. My conclusion is that the motor is not really 7Kw. Have you see a 7Kw motor?? its massive!
The motor is not running anywhere near 7KW based on battery and controller specs, but the motor is capable of producing that much power according to the manufacturer
That motor probably isn’t sustaining 7kw, even if you could do it 100 battery amps isn’t 7kw, that VESC definitely isn’t doing 7kw and the battery probably sustains just 3-4kw.
This is sickkkkkk not gonna lie I love them little Coleman bikes but you can’t cruise around gated communities at night without it sounds like a Dirtbike event going on… this is the WAVEEEEE

I built a little bike that goes about the same speed with only 2000w and it takes off really quickly too.
He is using a small outruner, those are low torque high rpm, you can't reduce the gear ratio enough to get in the powerband
Respect for this man
I was about to say there is enough room to install a range extender (battery charger generator)
The motor and controller support regen braking. No point in adding additional resistance to the driveline.
It just needs that Briggs and Stratton sound added……

Barry Allen here showed him how to do it.
That chain needs some kind of housing because it would suck if it broke when you were miles from your destination.
would be a great addition!
Yes, that indeed is a really nice "weld"
And in milliwatts it's even more impressive!
Very clever build, but could have been much easier with a Briggs and Stratton or a Predator.

Very interesting. Love this project.
Stronger lower voice when narration. Sounds like whispering.

Guys. it's 2024. Why is everybody still using chains? If you start from scratch anyways use a belt drive. Lasts you longer.

Would it be easier to use a rear hub motor instead of a mid drive set up? You would just need three plugs, throttle, ecu and battery.
We have considered going the hub motor way
