I just picked up this eBike at a garage sale buyout store.
With Google's assistance I was able to figure out that it's a Fuji-Marlboro Folding Mountain Bike that was offered as a promotion in the 80's by Marlboro. It looks to have been electrified with a
500W Cyclone-Taiwan kit. Chain drive. Motor is rated 24V 2500rpm, max torque 42kg-cm. The battery pack contains two 12V 10Ah SLAs and weighs about 30lbs.
Here's more pics:
I'm quite excited. I haven't biked in a long time, b/c I'm just too out of shape to beat the hills. But just last week I was pricing e-kits, and lo-and-behold, one appears... pre-assembled no less! I rode it home the three blocks and a little hill. My legs gave out after about 3 pumps on the hill (hey, the bike is 65 pounds), so I gave it a rev and zoomed the rest of the way home.
