Hello, i currently have an icandy apple jogger (3 wheeler) and am expecting my 2nd. I really want to convert it to a pear but it costs £400 to do in the shop!! I wanted to do it second hand but you can't buy the stabliser wheels anywhere individually!! Does anyone know if I can convert it using the normal icandy apple front wheels to make it a 4 wheeler? is there any difference between these and the stabliser? Thanks
