Although sturdy, the frame is relatively heavy. I think this bike is heavier than my adult frame bike.
The OEM grip shifter malfunctioned early. Upgraded to SRAM for less issues.
One way to know is you can check the shipping weight. The shipping weight on the Diamondback Cobra 20 is 36.2 pounds. The shipping weight on the Diamondback Octane 20 is 25 pounds. That's an 11 pound difference in weight and to a kid that will be huge!
