Yes, and also from school, way back in 1969. It had been a combined birthday and Christmas present and my folks couldn't afford to buy me another one either.
It was in the days when children still cycled to school, or walked, or caught the bus! (Yes, I know that SOME still do but if I walk past my old school now when the kids are coming out it is gridlock central ... 4x4s and people carriers double parked on double yellow lines, or even in the middle of the road!)
There used to be lots and lots of bike racks there and my bike disappeared during school hours. The racks were way inside the school grounds in front of several classrooms so unless it was stolen by a fellow pupil, the thief must have had the cheek to just stroll in off the street and go exploring to have found it.
My memory is bad these days that I sometimes forget what day of the week it is, but I can't forget the frame number on that bike. How stupid is that - it is 47 years since it was stolen and that number is still there - 4-8-6-7-7-1-5! I remember going to the police station to report its theft.
I didn't own a bike again for 20 years. Fortunately, I put the TV on after work in July 1989 and was immediately hooked on the Tour de France coverage on Channel 4. I bought a bike later that summer and have been cycling ever since.
