The most pleasant surprise for me from ebiking has been what a good workout it is. I really didn't expect this. I found this study which confirms my experience:

The secret is that you have full control over the amount of workout you are getting, so you just set the assist level to get a constant, sustainable, pleasant level of effort. You don't worry about hills. You go faster. So you can cover a lot more distance. Not to mention a large proportion of what would otherwise be car trips, can be pleasantly done on two wheels.
I am just more and more delighted with this decision to buy an ebike instead of a car, with every week which goes by. It's an incredibly versatile, useful vehicle, which gives enormous pleasure.
