I started cycling again a few years ago after a break of 30+ years to help me keep fit in retirement. I now have 5 bikes, cycle often and volunteer as a mechanic at a community bike renovation scheme. It's been a godsend at some very tough times.
My preference is mtb as we have coastal, forest and mountain trails nearby and I sold my road bikes years ago.
I sometimes feel a bit of an oddity on Internet forums as I'm 65 and didn't cut my teeth on mtbs in the 80s and 90s which gets me to the point of this thread.
What I like about this forum is that it recognises and addresses the issues that face older riders in a generally supportive and humorous way, and I don't feel patronised as an old geezer on a bike. There's no doubt that age does give you a better perspective on life, and I hope to give my perspective on issues in the future.
I might even get an avatar.
