So, a motorbike a passes a human powered vehicle? That should come as no surprise to neither of you. :)
To be honest, I don't get the appeal of e-bikes for the type of riding you do. Getting up to 15 MPH when you're riding for 8 km in a city when stopping for lights should be no problem without disabilities on a decent bike. An 8 km ride takes 20 minutes at 15 MPH. At 20 MPH it's 15 minutes. You'd add 5 minutes off your ride and get some proper exercise.
As a reference, my grandmother rode her bike 12 miles to school and then back at the age of 10.
E-bikes make a lot of sense for longer rides with cargo bikes packed kids, trash, food and whatnot.
Sweat. I do 2km twice a day for the school run in my unassisted mtb. On anything but a cold day, I work up a mild sweat. I wouldn't want to arrive at work in the state I get back in on a warm day.
Many commuters don't want to get "proper exercise" on the way to work. Hard enough getting secure bike storage, let alone a shower.
But I don't want "proper exercise" to be a part of my commute. I want to get to work or to a client quickly, efficiently and with a minimum of effort. I absolutely do not want to sweat through my shirt or arrive at a meeting in need of shower.
Snow =D I live in Canada and we have quite a bit of snow and ice on the roads in the winter. I'm currently waiting for an electric fat-tire bike (RadRover 6) which should allow me to ride to work without getting soaked in sweat.
I think most people in the North America and Europe live in cities that are so flat biking is just like walking faster. Maybe that's where your frame of mind comes from.
Where I live the hills are so steep that it's impossible to bike them solely human-powered unless you're an actual athlete. And even the more modest inclines will make a regular person give up on the thought of biking since it'd be a workout.
E-bikes are awesome for this, as they make tough inclines much easier.
or you have (and use) gears?
It will just take a while
Morning commute is not a moment where I have any interest in exercise, arriving sweaty at work, needing to always carry multiple sets of clothes, ...
I'd rather see it like the dutch, the bike is a tool for moving from A to B. If you want to do this while exercising more power to you, that's not my jam.
As mentioned there is more than that. An entire accelerates from stop MUCH more quickly which adds a significant element of safety.
By the way the bike share ebikes are like 30lbs and speed limited so there are plenty of times when my "motorbike" has been passed in the road by a well-geared human powered vehicle, friend.
