Every Jamis youth bike uses size-specific items like grips, saddles, and cranks that enhance comfort and control by providing the best possible bike fit. We focus on designing frames with low stand-overs to take much of the awkwardness out of getting on board and dismounting after. We trim as much weight as we can with lightweight aluminum frames on many of the youth models and use aluminum parts where possible to work towards that make-it-as-light-as-possible goal.
