Okay, so maybe it's not the end of the world, but I probably won't be able to ride my bike tomoorow.
I ride 48 kms a day on my Giant Cypress I've converted with a Wilderness Energy brushless hub. I use a 36V NiCad battery. On the way home, I stopped for a drink of water (it was 32C) and when I started again the hub didn't work. Nothing. The light was out in the speed control and since the battery seemed fine, I'm thinking it's the controller.
Any engineers out there with theories on why my usually reliable ebike failed?
