I know of this one old guy who is cripple rides the same trike I ask him why don't you get a motor for it I'll help you put it on? Nah blasy blah blah.
I feel so damn sorry for him to see him struggle with that trike I'm temped to buy him one out of my own pocket, but the guy is all f*** up over his entire body looks like the survivor of being hit by a high speeding car I dought he would be able to pull the cord to start it, he would need an electric start!
