I have a Trek eMTB and also a Boardman 29er. I use both of my bikes but for different rides. I use the eMTB for my adventurous routes like Church Stretton and Cannock chase and i use the 29er for a quick blast after work. When on the eMTB i have had a few funny looks and a couple of cheating comments. When this happens i try to engage in a conversation and then let them have a blast on the eMTB after 5 minutes you can see thier views have changed. I am 45 years old and a good hill has me blowing out my arse. I personally feel a eMTB with assisted help to 15mph just takes the edge off the hills on the trails i am travelling over 15mph so don't have the assistance. This sunday i came across a man on a full suspension normal bike and he was fast i managed to stay with him throughout the one trail and he pulled over and said " no one normally manages to stay with me " he gestured me to follow him down the next trail so i did. 2 trails later i was still glued to his back tyre and he pulled over and said " you are really quick" i then broke it to him that i had a battery..... his face was a picture. I offered him a go and he excepted he jumped on and said "what button do i push to make it go ". You have to pedal it i said he had a little ride and when he returned he was very impressed and was not what he expected. I think E Bikes will only get more and more popular. People that have injuries or are a little mature will appreciate the benefits of an eBike.
