Perfect bike for my 6 year old.

Comments about Diamondback Youth 2014 Viper 20-Inch BMX Bike:

The bike was the third installment for my 6 year old. He was previously riding a 16" BMX and was out pedaling the tiny cranks on that. This diamondback is the perfect step up with its 20" wheels and low profile frame. The duel brake system with hand and coaster has been great so far to teach my son to use the hand brake.
Assembly was simple, and it took minimal time to setup at home in my garage with just a few tools. No complaints so far. Great green color.
