My eldest is at secondary school. He’s got a 30 year old hybrid for “going places”.
It’s got mudguards, a rack with cheap panniers and a bell.
I got fed up of patching up a nicer bike after it had been piled on and walloped by every other kid in the bike shed.
When the youngest joins him we will be trawling the local gumtree/Facebook ads for something similarly uncool.
He doesn’t care – it’s freedom and transport and he arrives at school with a dry posterior.
Riding for sport/out with me he will poach any nicer bike he can from the shed!
Caveat he rides to school every day in every weather imaginable. I think in his nearly two years he’s had a lift in about 3 or 4 times. He therefore appreciates mudguards and panniers more than the average teenager!
