Sure, the style of bikes is changing, many gents bikes don't have cross bars anymore. One might say the bikes are unisex

However, my son is not going to change bikes to suit a kilt. I just wanted an idea of what riding in a kilt is like.

I think that what I should do is ride one myself and see!! I would think I may look a bit silly riding in a kilt, now if it were a fine horse - that would look the part!!
