Increase this adjustment setting either an increase in the steering tube length or to the handle bar post was proposed.
Regarding the handlebar width, the case study analysis showed that in nearly all cases the handlebars were wider from the shoulder breadth complying, therefore, with the constraints.
For the 20 and 24 in bicycle a reduction of 3-5 C. of the seat tube angle has been proposed, in order to facilitate comfortable riding and the perceived frequent changes of posture into more out of the saddle riding that can be expected by relatively old children (10 Years old) and young teenager
This reduction of seat angle led to an increase in saddle to handlebar distance, which in most cases was also desirable.
