We used a clothes pin to clip playing cards to the bike frame so that the spokes made a cool flapping noise. My parents gave up bridge, so no more cashews. That was OK.
If you saved your money you could buy handlebar grips with colorful plastic strips.
So you could fly down the street flapping and plastic grip strips streaming, impressing the little girl with curly hair by taking your hands off the bars and folding your arms over your chest.
And they were “Twids”: Little people about the size of a football.
