[Engelhorn]

Hello all,

Nope....never heard of them. Are they situated in India?

Gooooooodness. If that is actually legit, that is going to be insane... $600 for a 9kw system, disc brakes, and a lithium battery pack?? That seems absurd!! I am trying to build a 14kw electric go kart for $1k...... This is a bit cheaper... That's crazy wow.

may I call BS now or should I wait a minute?

a 144V 100Ah Batpack ALONE (no controller, no motor, no kart) is about 6-7 thousand dollars
and would last on a 550A motor (*cough*) for maybe 15min
A 144V motor (in that powerrange) with a 500A controller will pull another 4 thousand off your pockets...
add a charger (~1000) and a complete kart...

anyways; by adding a zero to the pricetag you might come closer to reality...
THAT up there is pure fiction.

They are welcome to prove me wrong, but seeing their kickstarter crapbike
zero innovation, zero invention, zero savings (same bike costs half that on chinese wholesale)
I bet they're just making some quick money with cheap chinese eBikes and then vanish as quickly as they appeared.

I may be wrong, but from what I read the owner raced EV drag cars and is now retired from racing. Their campaigns and website says all battery packs are built with Samsung cells in Westbrook, CT. It also says they build their own DC motors and controllers. Their ebikes are selling and they offer a 6000W ebike. Most campaigns offer a discounted price, maybe that's what the ad is showing?
I am going to keep an eye on this company.

I am curious, why did you price a 144V motor and 500A controller at $4000? Even I can buy a DC 144V motor for under $500 and controller under $200.

If you google prices for 144V 100Ah Batpacks, that is the pricing you get

 

[JokerBen321]

I'll have to check that out...

Where does it say these are 100AH gokarts?

Right in the list you provided, except that the one in the ad is 550A (which is actually more)

Really??? It does not show AH, just volts, amps, amps, and watts?

You cannot know the AH unless you know the C-rating of a cell, and for that you would need brand of lithium cell, which is not stated.

They could be using a higher c-rated cell for their ekarts, maybe a Headway, or A123??

well Engelhorn.. NOONE said it's a 100AH batpack ..
but a 550A motor can draw... well 550Amps obviously...
since you don't need that much if you're not going to use it.. it's fairly logical, that sometimes you indeed draw 550Amps from the batpack; at wich point a batpack with less than 100Ah is drained very quickly. (Ah / Amps gives you more than just a rough estimate )
So yeah.. 100Ah for a 12minute full pull is the least I'd put on a kart able to draw 550Amps..
maybe that's just me though

Show me the 550A 144V motor for 500 and the controller for 200 then, please;
that'd be a steal and I can stack some away to sell them on ebay
Oh and those are very likely AC induction parts... not DC;
if you find ANY 72kW+ DC motor with 144Volts.. again.. let me know (I highly doubt that!)

Yeah.. they make their own motors and controllers.. that's why the exact same pancake motor and the exact same controller is on ebay every other week shipped from china for a few hundred bucks...
again I call BullsShirt (you know .. chicago... red with horns and such)

It may be a typo

I think those numbers are just the prices for controllers - there's a similar graphic on the quad page, except it's clear it's talking about controllers:

 

[JokerBen321]

Ahhhhh that makes sense Dan. Just weird they don't show the prices for the other things. Maybe they are only going to sell the controllers individually? Weird...
