Water Boys ...... again .....

[Torchwatch]

I think that they bought a job lot of really awful looking girls bikes for this show.
It is set in a small town where life is controlled and rather boring reflected in the bikes they ride. Mountain bikes were around in 2003 when this was made but using them instead of sit up and beg girls bikes would have made the viewer look at the bikes instead of the riders.
Part of the joke is that they have really awful bikes, that the holiday centre they stay in has the same really awful bikes and yet they have to go on really desperate long fast rides on them throughout the story.
Most Japanese kids were playing computer games at home in 2003, yet this has been ignored for the sake of the story, giving Water Boys a slower perhaps 1950's feel.
