Diamondback creates high quality bikes for the entire family. The Cobra 20 is the perfect bike for the next step in a child’s riding progression. The heavy steel frame is able to withstand the uncareful nature of child’s play.  The 40mm suspension fork absorbs the bumps to create a smooth ride. The six speed twist shifter is a great way to introduce gear shifting in a young rider’s life. The Cobra is equipped with linear pull brakes that get your child used to braking with their hands, rather than with their feet.

Comments about Diamondback Cobra 20 JR MTB 2013:

I got this for my six-year-old for Christmas. I wanted a 20 in. bike with a suspension fork and gears. He loves it and it fits him great! The only complaints I have are about the weight and the shifting. I expected both of these to be an issue, but by the time summer rolls around, it should be fine. The bike weighs about half as much as my son does. He's able to handle it just fine, but he gets a little nervous when he's getting off. The problem with the shifting is simply the fact that the twist shift shifter is too hard for him to twist. If the rear derailleur had a bit lighter spring, the shifting would be perfect.
