Super quick update. Reassembly and wiring for the electric crosskart buggy starts today! I'll have the first of the final two videos for the build series ready to watch here on April 10th at 9 AM AST. Make sure you're subscribed and notifications are turned on so you don't miss the test drive!

Bro you keep us in suspense. I jumped when I saw "James Biggar" in my notifications 😅
i cant wait for the test drive
The level of detail and the fabrication skills here are immense. 👏
It’s looks great and good but it’s hard to wait the test drive
Good work 👏
Looking amazing!!!
Surreal. Looks great man, bold choice with the orange
Great color choice
good work brother. cant wait.
Can’t wait to see
Very good!
I'm so ready...
This looks awesome! Great work!
You tease 👍
Ohh man!!!
Лаконичненько так. Покрасил и молодец. Утопился видимо, можно и отдохнуть. 😁
it looks great ; it reminds me to the jeep from half-life 2
Looking good! KTM might have something to say about that scheme though!
Thanks! Who cares what KTM thinks, though? It's technically Allis Chalmers tractor paint 😜
Is the assembly video coming soon?
The assembly video has been ongoing for nearly a year lol. See the build series playlist in the description.
I should add that the test drive video will include installing the batteries, wiring, programming, etc. So everything should be covered by that point. If you have any questions, fire away.
@@JamesBiggar 5 days 10days 15 days 20days nearly?? I can’t imagine its perfermence I don’t know what I can get this buggy’s catalogue
Another 365 days if people keep complaining. I'm in no hurry.
Drive it already, jeeez :D
How heavy is the frame?
~200 lbs. Total curb weight with the battery will be somewhere between 800-900 lbs (will weigh in the next video), on par with a typical gas powered crosskart or buggy of this size, which most guys build with larger, thicker walled tubing, but less of it to decrease the workload. I used more smaller tubing with thinner walls to provide the strength needed to support the battery and compensate for the extra weight. It's just a LOT of planning in the design and a lot of work notching and welding the extra trusswork. For perspective, this buggy will weigh around 200 lbs less than a Polaris RZR 900, and have the same peak hp. Or ~100 lbs lighter than an RZR 570 and 25-30 more peak hp. Not exactly comparable to an actual racing kart, but it has more than a good enough power to weight ratio for me to rip around the trails and have some fun without killing myself, hopefully.
Класс!
I personally think that motor you used is weak, at least from the reports of people testing it, a couple QS 8000w motors would be real nice. However I can not wait to see this buggy move!
I think they're mistaken, from reports of anyone I've seen testing it, and actually using it. See the Ghost car that a guy I follow is building - >1000lb and he's peeling the rear tire with just one motor (he later added another, and it's a neck snapper, channel link below). The supplier tests them at any voltage (must be requested) before they're shipped and provides a power and torque curve chart, as well. Hp is hp. Torque is torque, doesn't matter what it's coming from. So the aim is energy and cost efficiency. Let's break down the #'s. The ME1616 produces 24 kW continuous and 55 kWp (72 hp) with liquid cooling, half that with air cooling according to my data sheet (available on my Facebook page). It weighs 48lbs and retails at $1200 CAD from electricmotorsports.com. A couple of 8000W QS motors (I assume you mean their new QS180 90H mid drives and not the less efficient and heavier hub motors) would only be 16 kW continuous, 32 kWp, but each would weigh 47 lb and cost $900 CAD, or 94 lbs and $1800 in total. So two of the QS motors would be 4-8 kW weaker in continuous power, weigh twice as much and cost nearly twice as much, too (not to mention two controllers would be needed). I've used QS motors in all of my past builds, I didn't use them here specifically because they're too weak for a ~900 lb machine imo, and too expensive. The ME1616 provides more power per $ in cost compared to multiple motors, more efficiently. I wouldn't go so far as to say that one of these is sufficient for a racing kart, though. It's going to be fine for what I'm doing, but an actual crosskart/rallykart has twice the power. I can see others or even me 'maybe' later on ditching the rear diff, adding another ME1616 to power each wheel independently to eliminate the need for the diff, and building a new bank with battery hookup's 6 Ah cells for close to twice the power. The only thing I'm concerned about with the current setup is syncing the motor with the Kelly controller. From what I've been told, others have had problems. But I can always use a Curtis if I have any. kzhead.info/sun/kshqpaZvqmprhqs/bejne.html
