Disadvantages of e-bikes

We are both over the biblical age of three score years and ten. We have just  bought a couple of touring bikes. When we announce this, our friends and acquaintances all ask the same question: "An e-bike?". They are often surprised to hear that the answer is, "No, a staid normal touring bike with an eight speed hub gear".
"Why not an e-bike?"
Two answers:

• An e-bike would not fit into our mode of cycling. We often take a train somewhere and then cycle on. It is important to us that we can easily lift our bikes onto trains. An e-bike weighs around 26kg. Our touring bikes weigh 14kg. In the two minutes that Deutsche Bahn allows to get our bikes onto a train the extra weight makes a big difference.
• We store our bikes in our cellar. It is difficult enough carrying a 14kg bike down a tight curving staircase. A 26kg e-bike would be impossible.

If we lived in a hilly area then matters might well be different, but we live on the Rhine plain. This does not rule out hiring an e-bike in a mountainous area in future.
