Ok, I got my bike after an extremely long wait. The box was beat to crap with part of the pedal assembly hanging out. Upon opening the box, it was clear that the packing was not up to par. The bike was lose and when pulled out there was damage all over it. From the damage on the frame, to the damage on the top of the frame to the damage to the things that stick out looking like some sort of turn signal or brake lite. Upon putting it together, I tried to open the battery door; I couldn't open it and it is made out of plastic so i didn't want to put too much pressure on it. I still haven't been able to get it open. There appears to be two little lights on each side at the rear. Since there is NO instruction book with the bike, I have no idea what there purpose is. They don't work with the brakes and don't seem to do anything. Although there are wires connecting them to something. The screen does show some information but the measurements are in KM and not MPH. Again, since there is NO manual with the bike, I have no idea how to change it. The chain has come off several times and this is a pain while riding the bike. I get this was a 1st gen of this product, but, even though I waited over a year to get it, I would rather have waited a little longer to get something more refined. It does go fast (I read somewhere that I can change the speed but again, there is NO manual) and rides fine. The bike does seem somewhat unstable as there is no way I can ride it with one hand. Attached are the pictures of the bike as received.
