The Charger is a better bike but compares directly to the Kona Blast, at $899. Going to toe-to-toe with the Nunu is the Norco Storm- they're the same price and are spec'ed nearly identically. The biggest difference is that they come in different sizes. Kona's sizes run 14/16/18/20/22 and Norco makes 12.5/15/17/18.5/20. Ride both and pick the one that is most comfortable. You can't really go wrong between the two so if they feel the same, pick the one you think looks best.
