I spied an electronic assist bike at our work bike rack yesterday. First one I've seen in the wild. It had a rear motor that looked like a big drum brake hub, and a battery pack that was loaf of bread sized on the downtube. Otherwise, 7-speed grip twist shifting on the right, e throttle on the left. With fenders, ortlieb rack and left pannier, and plenty of handlebar mounts for electronic gizmos, it looked seriously set up.

Impressive. Now, to meet its owner...
