Still use an ugly grey speckled OGK 1980's vintage.
I'm 48 and still have my first 10 speed racer, bought in the late 1970's. Got the OGK helmet when Australian road rules changed and we couldn't ride without one. (My 60yo husband has an attractive white Bell helmet, however his has a bright red speed stripe around the rim. ;) ) Back then there wasn't the style choices we have available now. My old 10 speed hasn't had a lot of use, it's never been in a race, and still has it's original (now perished) tyres, which will be replaced soon. It was only ever used as a short distance commuter around our small city and I'm about to start using it for that purpose again. (Saving my new bike for the longer rides.)
Bike riding became less popular here once the helmet law was introduced. Up until then there were many older people who rode regularly to shop and visit etc. Then they seemed to disappear. "Helmet hair" was not popular among the "blue rinse set." I think everybody just became reliant on cars instead.
Now that there is a focus on health and wellbeing many more people are exercising in different forms (jogging, walking etc.), and more cyclists are beginning to appear. That's part of why I'm riding now. I love the freedom and I can go much further quicker than I can walk, and it doesn't really matter if I am by myself. When I ride I'm very much more aware of my surrounds.
Our country regional development board is in the process of promoting our region as a cycling destination for tourists and locals. So, hopefully more people will take up this activity in the future. The more the merrier.
P.S. It amazes me when riders don't acknowledge other riders. It only has to be a nod, especially when you are the only ones on the road and meet face to face, so to speak.:D
