NOS...............WTH

Well get a load of this a e-bike with NOS well thats what it looks like. But how can this be possible on an electric bike?

HA HA HA GOTCHA its just an energy drink bottle but did it turn alot of heads the other day. I went over to a car cruise night on my scooter and was talking to the guys there and they got a real laff from it but people who dont know anything about electric scooters said " Hey isnt against the law to have NOS on your scooter?" or " Holy crap man that thing must fly with NOS"
