I've had an idea for a while now of travelling through africa on an ebike, more exactly a tadpole e-trike. Ideally I'd go from my place in Johannesburg, to Cape Maclear on Lake Malawi and back. Now obviously this is a long way, about 2000km each way. I've read trip reports, and a lot of unpowered bike tourists manage about 100km per day pretty easily, so I'd be looking at 40 days worth of riding time, and I imagine about two months to complete the trip.
So what I was wondering is, how feasable is it to run an ebike directly off solar panels, removing the batteries from the equation completly. It doesn't need to be fast, nor does it need to be able to carry me up a hill on it's own, but how much pedal assist could I potentially get? I know it would be simpler with a battery pack that charges off solar, but lets say for arguments sake I don't go that route.
If I put a canopy on the bike and cover it in effecient solar panels I imagine I could get around 250w worth of power, depending on the size of canopy. I saw this trike here which works along those lines: http://www.solartrike.com/canopysolartrike.html . Now I never trust sites claims when they have a financial interest in stake, so what do you guys think is possible? Could I hook up a solar panel, directly to a controller and a small motor. I'm thinking a high wind version of the 9C to keep things simple and reliable.
