Thanks Jon pretty much confirms what I thought, except the up and down could be a function of weight distribution on the gas shocks. Also the banana seat on this one allows for rider to stretch his legs as well.

Could always put 2 of those zombie bikes together to make a scaffold and use them to change the street lights otherwise nearly impossible to mount or dismount if you are not a circus performer
