I have just clocked 85ish miles on my Airnimal retro fitted with a 2 speed XD rear hub and a 36v 17.4Ah battery. I pedal a fair bit and rarely go above level 3 (out of 5) and this has included many 100 m of climb. I'm dead chuffed with it. My average speed is only about 12mph though. Any faster than 19mph and my legs can't keep up so I take a rest and freewheel.
I once went out on my bike with Strava running on my phone. When I got home I forgot to turn it off and it ended up recording a few KOM after I got in the car and did a journey. I left it on the APP for comedy value but it pretty quickly got deleted after a load of "serious" roadies got the hump and flagged it to Strava (and sent me some arsey messages at the same time).
