John, you don't need to 'modify' it. Just like any car with adjustable steering wheel and seat, the ELF has to be adjusted to the driver using it. As an expert user and owner of three years I know what I am talking about. Your words indicate you do not. Reclining meshed recumbent bike seating is the finest in the world for comfort.Mr Gordon, I shared facts and my opinions as an ELF owner and don't consider your "corrections" accurate or unbiased. I should not have to modify an $9000 bike because the seat does not adjust enough.
