Awesome! Today's e-bike is the 'moped' of my youth. A friend of mine got one of those that had the engine in the front fender, and literally rode it to death. He zipped everywhere, and always seemed to smell of premix and 2-cycle exhaust. But he literally rode it to death over 3 years. It was clunky, back then, and yet somewhat popular.
I've been looking at a couple e-bike cargo bikes. Great idea! If they were more affordable, and had a good way to carry big things, I'd likely have one. The stores are just far enough away that taking a car is almost mandatory. And the roads are nasty enough that doing the cargo would add quite a few miles depending in the store, AND not many of them have bike racks, or charging stations for e-bikes or electric cars. It's a crime that people don't see electric anything as being important. One strip mall went and put in a 6-bay electric car charging station, very hi-tech, and it's sat for 6 months waiting to be connected to mains power. The meters and connections aren't there yet either, but it is listed as 'available'. *groan*
But I rant, and it's Saturday.
Great idea! Ride on!
