Ebike virtues
Having owned both a carbon road bike and an ebike, The carbon road bike has a complicated derailleur gear system that needs to be cleaned every hundred miles or so, sometimes less, it also goes out of sync with regularity requiring some form of adjustment, and that adjustment isn't really working well for me because it skips gears. Because the parts of the carbon road bike are optimized for weight they are also kind of fragile and need to be replaced often because of their fragile nature.
The ebike has a belt drive and an IGH. Both are less efficient than a chain system but are gobs of less maintenance. It also can run bigger and less efficient tires for a more comfortable ride. As well, it can take a suspension system too and still maintain speed.
When it runs out of electricity like what happened to me today it is a bear to limp home in.
