I was hoping to get some opinions on cargo bikes I'm considering. We have a really good bike shop in town and a passionate shop owner who really believes in his products, but I'm wanting some other opinions. I bought 3 ebikes from him and my wife and I enjoy a biking life, but we live up a very steep hill and she was just diagnosed with MS. Thus, she often doesn't feel like biking, so I want an option where I can put her on the back of a bike with me and we can still enjoy biking together on the days she doesn't feel like expending that energy. So, I'm really looking at the cargo bikes and my main important features are: - comfortable seating options for passenger - really strong electric motor so that I can receive some considerable assistance getting close to 400 lbs worth of human flesh up some fairly steep hills (between my wife and I). I bike a lot and go up and down these hills with relative ease, even as a big guy, but throwing my wife on the back is another topic. Thinking about the Felt Bruhaul, the Radwagon, the Pedego stretch, the Yuba Spicy Curry.... Since I understand more than the basics about electric bikes and bikes in general, I'm really posting this because I don't understand how the Radwagon can be so much cheaper than the other options, based on the incredible reviews. Yeah, it's heavy, but so am I. What else am I missing? Longevity? Ease of operation? Any professional opinions out there?
