Every Jamis youth bike uses size-specific items like grips, saddles and cranks that enhance comfort and control by providing the best possible bike. 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. The additional benefit of this spec-as-much-alloy-as-possible design bias is that the product will hold up in the elements significantly better (with a much slower and lower oxidation rate) than other kids bikes built with more steel parts. We know because we have kids too and their Jamis bikes are often left outside for much of the year. We’re amazed at how good these bikes look 3, 5, and even 7 years later.
