2011 Hotrock 20 6-Speed Boys
|
|
A lightweight, low-standover height frame with properly proportioned and easy-to-use controls makes the Hotrock perfect for a kid's first multi-speed bike. 50mm of travel on the front fork takes some bite out of the bumps.
Features
20" A1 Premium Aluminum ATB frame with low standover height for care-free starts and stops with room for full-sized water bottle
40mm-travel suspension fork with lightweight alloy lowers and pre-load adjust takes the edge off bumps for more control
Lightweight 32-spoke alloy rims are durable and provide a stable platform for learning
Specialized Roller tires provide a knobby grip for dirt, but roll easily on pavement
Forged alloy crank arms give big kids more power, and a chainguide keeps pant legs clean on the way to school
Adjustable alloy V-brake is light and reliable - perfect for kids' transition to adult bikes
