I've ridden them in the past, but today I commuted home on one, around 16miles, which took just over an hour, and had a great ride on the way home, took the scenic route and had a blast.
I'm very much not into my climbing, years of smoking at university and a shit leg means that almost any hill I come across will result in legs feeling like they will explode so I'm 100% pro E bike.
What about you chappies?
