Can anyone tell me what sizes the wheels range from and which models use the smallest size wheels. The reson for asking is I read in one of  the listing I came across the RS bike used 16 inch front wheels but I cant seem to find any RS bike with 16's fitted, any feedback would be useful as I want to lower the centre of gravity without cutting the frame on my BMW diesel K100 self build project.
