Mountain Bike Action Bike Test: KHS Sixfifty 6555+E Trail Bike


this is one of the best and lightest bikes we’ve ridden. There seems to have been little compromise made to make this bike handle at the level it does. We think they’ve hit their goal of providing a high-quality bike for a moderate price.
