I've discovered that attaching brushless hub motors to the exterior of plastic kids cars makes for an awesome upgrade.
My latest build uses four brushless hoverboard motors. Originally each motor was 350W @ 36v, so now I'd estimate the total maximum power output is 2489W @ 64v. Currently its top speed is 72kph and I'm fairly sure that's a world record.
As this build was a resounding success, the focus has shifted from "Does it work?", to "Let's make some more as cheaply as possible."
Hoverboard motors are hard to come by, and brushless controllers aren't cheap either. I realized that switching to brushed motors would reduce complexity, lower cost, and improve low-speed torque.
Only problem is: I can't find any such motors anywhere! There were a few threads from 2008 or so that discussed one specific ebike's brushed motor, but I haven't been able to find much info otherwise. And no leads as to where I'd find some for sale at a good price.
Any ideas or suggestions?
