Also illustrated on this page are Murray's trainer wheels, both deluxe and standard, which are available as an accessory item that can be purchased separately. Murray also gives their size recommendations, which is interesting. When you click-on this thumbnail picture you will see an abnormally large feature picture; this was done intentionally so you can read the fine print.
