I have no objection to e-assist bikes. They are great for people who haul lots of cargo/kids/whatever, for older/weaker people who live in hilly areas, for anyone who otherwise wouldn't get out on a bike. However, I have given my wife clear instructions: barring unforeseen medical issues, if I come home with an e-bike prior to my 75th birthday, she is to return it for a refund and put me in a nursing home.
