My dad and his brother was a regular cyclists in the 1940s and 50s, not racing or club cycling, but they used to think nothing of riding from Bristol to somewhere near Gloucester...then back. They'd have been early teenagers...riding IRO 60 miles. Granted they'd spend the day in Gloucester so it wasnt in one hit, but even so, for young teenegers on bikes that certainly wouldnt have been high quality....
I remember when i was looking at spending IRO £500 for a bike...'what' he said...you dont want to be spending that much...its the man, not the bike.
Several months later, we were talking, he said how his first good new bike cost him a months wages....hmmmm, equate that to todays wages...i'd be spending £2000 on a bike, not £500. Yeah right dad....do as i say, not as i did eh ?
He also said, in the 1950s (i think), you'd see packs of cyclists maybe 50 or 60 strong, regularly. Enormously popular back then. Mind, as he said, there was bugger all else to do back then. Everyone had a bike !!
