Thanks for starting this thread socci, I stumbled on them while browsing the net last night, My DS (3yrs) insists on riding his trike in the house, We have laminate flooring throughout and was thinking of treating him to one so the trike can be kept outside. I know he would love whizzing around on one of these, my only concern is he like to bump and bashed into things, adding the rubber sounds like a good idea.
