I was driving home with ten sacks of 60 pound concrete when I saw the smallest
carts I have ever seen in the parking lot going really fast...so I investigate.
4 motors each 8kw an inch and a half or so in diameter x 4 inches long. All
running toothed belts to the .....skateboard wheels. 0-60 in two seconds.
Having four motors it spreads out the thermal. No trouble with overheating. The
guys were "having fun" and are into tech as a job. This was just their "fun".
Looked like a mature product. They just had small battery packs on the cart.
Lithium. 18650's. That is why I enquired. They said they had a "China"
supplier. Their words. Hundreds in parts...not much but the batteries cost.
Pushing one guy he said...maybe we will do a gofund me. They really have
something. Lawrence Rhodes
