Dutch native here. As a casual user (school, commute, etc) I owned 3 MTBs in my life. One I bought second hand, other two new (1 of which got stolen). The former was a lower quality one, the other two certainly had bar ends. And I liked and used them. I never used a helmet, except when I went on survival hiking. That was in the Ardennes, and was all pro material though I don't remember regarding bar ends. I am actually in disbelief about them disappearing. What is the source? Where is the data based on?
