Handles, pedals, brakes, and tire chains are very reasonable things
I come to see his precious vehicle when he tells me "I’ve learned a new trick!"
Even if he gets covered in dirt and sweat, and even if his scrapes and bruises hurt, he still won’t give up.
That’s because he likes it an awful lot and thinks he should be able to do it. My heart hurts a bit.

jitensha aitsu no koto o muchuu ni saseru miryoku wa naani
jitensha fushigi na mahou lalala choppiri kuyashii na

Oh, bicycle, just what is it about you that makes him obsessed with you?
Oh, bicycle, you are a mysterious wonder, though I must admit I’m a bit jealous.

ano sakamichi no teppen made yukou to aitsu ni sasowarete nottemita kedo
iki ga kirete tsurai dake kore no doko ga tanoshii no akiramekaketa sono toki
saka no ue no shiroi hana todokisou na kyori dakara saigo no chikara o shibotta

He said "Let’s go to the top of that slope!" So I got on the bicycle.
But it was very tiring. What about this is fun? I was just about to give up, until…
I saw the white flowers at the top of the hill and it looked like I could make it, so I gave it my best shot.

jitensha sora ga hirogaru miorosu machi ni yuuhi ga ochiru
jitensha sagari no saka o lalala kakedashi hajimeta yo

Oh, bicycle. The sky is so broad. The sun is sinking behind the city.
Oh, bicycle. I’ve begun to speed down the slope now.

jitensha kaze ni toketeku aitsu no egao mawari no keshiki
jitensha fushigi na mahou lalala konomama dokomademo
itsumademo yukitai na

Oh, bicycle. I’m racing in the wind. His smile blends in with the beautiful scenery.
Oh, bicycle. You are a mysterious wonder. At this rate, I wouldn’t mind going anywhere.
I’ll always want to go with you.
