Specialized's Boy's Hotrock 20 Coaster is an easy way for little kids to step up to big-time fun. It features an aluminum frame built to withstand the rigors of childhood bike riding and a rear hand brake to get him ready for bigger bikes down the road, while the coaster brake provides a familiar backup to facilitate the learning process. Plus, the Hotrock comes with fat, knobby tires for serious traction on all types of terrain, too.
My 5 year old was riding a 12" Specialized Hotrock, and needed to upgrade. The 16" Hotrock was the right size, but easily outgrown. We compared dozens of bikes, the 18"ers we found were heavy and cheap. Went to the local shop and they removed the rear reflector from the 20" Hotrock and dropped the seat down all the way. It was the lowest of any 20" and almost where the 18"ers sat. The bigger wheels roll over bumps, the breaks are amazing he stops without skidding and can touch his toes on either side. This bike can scale up for years. The chain guard can get pushed against the pedal, but just reset with your hand- its thin metal. Tires are upgrades and seat is top notch. I'm 5'10" 180lbs and I rode around on this thing with no worries.
Bottom LineYes, I would recommend this to a friend
