I have my zinger tore down to the frame, and going to be rebuilding it soon too. I like the idea about the hand grips...i might do that too, but I dont know if that rubber is too soft and will rip easily....it will probably hold up good if a child rides it, but if an adult rides it, it might rip soon, but its a better of an idea than the previous owner of mine had, wrap foam around it and wrap the foam in electrical tape. Seat cover looks good too....I recovered mine with vinyl also.
Lookin good
