Well...for Aiden it's more like trailer riding.
We bought a bike trailer last year and Aiden wasn't a fan of it. He seems to do better riding it in this year, we're still working on making helmet wearing a fun thing. He doesn't always love it. What he does love is that Daddy takes him to different parks to play on while riding around. The advantage of living in the city.
Maybe next summer Aiden will have his own bike.
