Even traditional good quality bicycle easly can cost $1000, I mean build from first class components.
Wen you add electric partrs it must cost more than $1500.

I would disagree you need to pay that much for quality.
$300 can buy a "quality" entry level bike. (aka no walmart stuff.) $500-600 will get you a fairly well equiped bike most places. $1000 is a pretty top shelf bike.

Same deal on the electric kit. You can get into the game for $500-600 for a competent, but slower, heavy, and short range kit. That's from well regarded dealers with generally well received motors. Of course you'll be running SLA and not LiFePo4.

All depends on your expectations I guess.
