This is my younger brother sitting on it.. I am even shorter then him so just imagine.. 
I agree with you Umer but on tours bilal ganj wala kam fail ho jata hai.. I had an option to install a Honda or Zuki trail 4valve engine even they had way way more power then this china engine but they are complete failure for a person who do long tours. becuase unky parts nahi milty..
These engines are CG250cc engines whos downcast 200cc variant is widely used in sazgar rickshaw here locally so that means where ever you are you will find most of the part which are adaptable from Honda CG and other parts can be used of orignal rickshaw and your touring will never fail.
Yes I do remember I have not down any changes to the engine this engine is a Ripped out of a dead accidented trail from Karachi which was of same breed as my one, its a CG250 series engine and 5 gear transmission.
Thank you Ammaar you will puke F again when you will ride it
