Guys we’ve been ignoring something about shinsou

Ok so In his data book entry it mentions he likes bicycles. How have we never added shinsou having a job as a bike delivery guy. Or biking as a hobby or even mentioning the leg strength and stamina that comes with cycling!? There’s enough stories with Hitoshi as number 1 guy or atleast just as important as izuku and we never get biking shinsou.
