1991 Specialized Rockhopper Mega (20″ wheels)

Serious and very rare all-terrain bike for 4’5″-4’9″ riders (7-11 year old kids). Mini Rockhopper frame, Sugino alloy crankset, 7-speed Shimano drivetrain, all-terrain Ground Control Black Max 20×1.95″ tires.

This bike is simply awesome!

I am restoring this bike now. Let me know if you’d like to modify it for your child.
