I don't own one but I did ride one a few weeks ago as my buddy is an avid cyclist. I believe the one I rode was a Specialized (don't quote me on that) and it is pedal assisted, I rode it down the road and had it on full battery power and holy [bleep] did that thing want to go. I couldn't peddle fast enough to keep up with it, if they weren't so damn spendy ($6k) i'd own one.
