Well at 81 having returned to regular cycling after a very lengthy gap (1980s) the pleasure is there. But..... you have ride within your limitations: you tire very easily, hills - accept that even moderate ascents are more than just difficult - and distant rides now translate to less than 20 miles.
The bikes are: a 20 year old Genius Volare, a
Ribble and of
late an Orbea-Gain M20. The latter being an acceptance that a little assistance is needed on anything other than on tarmac and traversing minor gradients
So if you 60 year olds see me wobbling around the New Forest back roads - wave, & just think "I've got a other 20 years in me" and enjoy your life and the ride
