Funny- I sort of had the same attitude as Exit until I actually tried an electric bike. Beyond everything else the electric bike was a lot of fun - you press the throttle and take off at 20 mph in total silence. If you gear your bike right you can go quite a bit faster than that with peddle assist.
I love cycling - I commute to work every day, often do 40+ mile rides and have no trouble climbing hills but I am building an electric bike to use as a secondary bike mainly because it is fun.
