I have an Whyte e-150RS mtb and was a little sceptical until I tried one. I thought ebikes were for the unfit etc etc. Turns out you can work just as hard but you get mote of the fun stuff! Llandegla is my local trail centre and I can do two laps of the black route in the time it took me to do one on my anolouge bike.
The only issue I've found is cost. Not just to buy the bike but also due to the weight and tension the bike is put under you go through perishables at a rapid rate!!
