The KOS line has grown this year. Originally ridden by Mongoose® Factory Team Rider Jeff “KOS” Kosmala during his glory days in the 1980s, the KOS has plenty of old-school style and special components designed specifically for it. This year we've added a special Signature model and the 24" Kid Kruiser.
