I've recently bought an ebike, it's rocked my world TBH.
It took quite alot of persuaion by OH to get an ebike (theres a whole other thread about why, ill health, unable to ride old bike etc).
The clincher was when OH said (and this turned out to be quite true), although it will be easier, you'll ride more often so you will still reap massive health benefits. He was very right. Since I got my ebike I've ridden further than I usually would because it's quicker and easier.
I live in Sheffield, which is very hilly. This can make even short journeys a bit of a chore. The ebike takes the sting out, so I'm using the bike alot more than usual for short errands. I can carry more shopping because the battery takes the sting out of carrying more stuff.
I'm still on sick leave at the moment, but I did have to pop into my workplace last week, so went by bike. I was amazed that my ride time home has reduced from 40 minutes on my old bike to 23 minutes on my ebike! Thats 17 whole minutes faster! And I didn't arrive home purple in the face and drenched in sweat!
Other advantage - I have a 10 yr old son who's as fit as a flea. I can't keep up with him when we're on hills usually. On my ebike I can, so he doesn't have to hang arround waiting for me at the top!
Someone mentioned - just buy a moped. Well, that was something I'd considered, but part of the problem for me with that idea was that to a certain extent you're still stuck in traffic. When I return to work I'm reliant on cycling as I drop my son at school, then ride in to work. In traffic, I can't possibly do it in time, on the bike I'm using alot of off road routes and contraflows that I wouldn't be allowed to use a moped on - this is partly what swung me towards the ebike over a moped. Other thing - moped insurance is very expensive round these parts. Obviously, I wouldn't be able to ride with son using a moped either.
The only downside I've found is the limitation in the milage. I think I get about 30 miles per charge (due to the hills, others have reported much longer distances). I came home with a very low battery one day last week and it was quite hard work, though I did get home before it went kaput. Due to battery/motor the bike is heavy, so I really wouldn't want to try to ride it without power!
Also, I haven't tried taking it on the train yet. My bike has the battery behind the seatpost, so it makes it that bit longer. And again, because of the weight I'd struggle to get it ino one of those racks where you hang it up by the front wheel.
So, like alot of others, until I needed one, I had a bad attitude towards ebikes. But at the moment, for me, it means that I can go about my buisness on two wheels. Initial plan was to use the ebike until I return to full health, then sell it on. But TBH, I can see me using it at least for commuting, forever. Getting home 17 whole minutes earlier is not to be sniffed at is it?
