2009 Specialized Hotrock 20 Girls Coaster purple

Cute and reliable bike for fun and easy learning. Best for 4’0″-4’5″ tall riders (girls around 5-8 years old).  Simpe single-speed drivetrain, beautiful artwork on the frame, and 20×2.125″ Roller tires that would smooth your child’s ride on any terrain. Check this bike’s page on BikePedia. MSRP: $220

I got this bike with a badly rusted chain, badly scratched handlebars, and rust spots on the fork and handlebars. I deep-cleaned this bike, de-rusted all rusted components, repainted the handlebars and fork in gloss white, and installed a new saddle and handlebar grips.

This is Mereleine’s bike now.
