Just picked up four of these at
King's on sale for $2.99 each. (Didn't have any 49Mhz otherwise I would've bought five.)
The package says CYCLONA SUPER NEW BITCHAR-C CAR. Note there's no space or hyphen in bitchar.
Wheelbase is 1.25" and overall chassis length is 2-5/16" The front and rear of the chassis are pretty much a straight clone of the ZipZap, width in the middle is the same, looks like the shortening was done between the rear axle and the center of the chassis. There's a prominent mold line vertically up the center of the sides.
After a couple of runs on the shop floor, it wouldn't steer. The steering magnet had attracted small metal filings which 'short circuited' the magnetic field. My ZipZap can still steer even after picking up a load of filings.

A quick blast with the air hose restored steering. I'll have to either clean the shop floor better or find a cleaner place to run the cars.
Body detail is minimal, clear plastic painted on the outside in orange with black roof, red on taillights and blue 'mask' on the front with headlight area left clear.
The body is slathered in stickers sporting engrish phrases like
