Torker's Unistar CX is a proven classic. Sporting a steel frame, the Unistar is durable and tough. The small 16-inch wheel is great for younger riders and runs on precision hub bearings for smoothness and reliability, while the quick-release seatpost makes seat adjustments quick and easy. And speaking of seats, the Unistar's seat gives you comfort and balance and boasts bumpers to protect it, too.
