Gary, I have a spare unused complete rear wheel with brushed hub motor from EV Global, which was a Lee Iacocca design from 1998 or thereabouts. This is the first version of their e-Bikes so it was used in a 24V bike, later bikes use 36V but I do not know if the motor is the same or upgraded for 36V, it might well be the same motor. I have run the same motor (I have a 24V EV Global that I use for all my riding) on a 30V Lithium pack and it is very powerful, it will lift the front wheel for a short moment when applying full power from stop.
I do not know the rating of the motor itself, but it definitely is at least 400W continuous and higher peak power. The official specs from 1999 mention 400W motor: https://web.archive.org/web/20000229083229/http://www.ebike.com/standard html.html The whole bike is designed for quality, it is very rugged and even has a VIN so I am expecting that the motor is also high quality and can withstand some torture but you'd need to ask anyone more knowledged about this particular bike to know what it can do (or test it while monitoring the motor winding and brush temp) I do not need the spare since the original rear wheel has been flawless in the 5 years that I have been riding it (I bought the bike with less than 200 mi after it sat 12 years in a garage) and later bought the unused wheel from someone who put a brushless wheel in their EV Global, since the brushed motor is noisy, not conducive to riding trails if you want to see wildlife. I always ride the bike without turning it on, only using the battery to run the powerful head- and tail lights. Make me an offer - local pickup is preferred (I am in Silicon Valley) but I can ship.

I'm advising a group competing in the Shell Ecomarathon competition (http://www.shell.com/energy-and-innovation/shell-ecomarathon/americas.h tml) . We previously powered our vehicle with a 36V, brushless DC hub motor designed for bicycles. The problem is Shell requires a motor controller custom designed and built by the students (even though you can buy these controller off the shelf for like $20). Because we're mainly a bunch of mechanical engineers, our attempts at designing and building that brushless controller have been.less than successful. For this year, we want to use a 36V "brushed" dc motor to make this custom controller much easier. Ideally, a 36V brushed hub motor in the 500W-1,000W power range would be best as it would be nearly a drop in mechanical replacement. Problem is, we can't find such a motor. Does anyone have any suggestions of commercial motors that might fit that need? If not, we'll be switching to a brushed motor and a chain/sprocket drive.
