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-over 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 (the limiting factor here is working within a
youth bike appropriate price point) to work towards that make-it-as-light-as-possible goal.
