I bought an X27 4 weeks ago.
My commute is 11 Miles each way which includes a steep hill rising from 80ft to 550ft in just over a mile which the bike handles with ease.
I am 13 stone 4 and I average 17.2mph (slightly sweaty) if I push on and 15.5mph if I take it easy (no sweating)
I use level 3 assistance (scale 1-5) and can go 2 days (44 miles) between charges but I charge every day as recommended.
I took the bike to my holiday cottage at Loch Tay a trip of 46 miles with a heavy pannier on and still had around 20% battery left and this route had a serious 2000ft climb over 5 miles, I stopped half way up as the motor overheat warning light started to flash, after a break of around 30 mins it was fine.
It is certainly a well built and comfortable bike, everything works, no rattles and I have just passed 600 miles.
Can give you some data showing this from my mapyourride page, shows my commutes at 37-40 mins for 11 miles
