How about some live music instead?
I can also usually play along "by ear" with most songs I hear from a jukebox or other device. Most people enjoy it. There are sometimes spoilsports, and if they are the ones putting the quarters in of course I won't play.
Oh look, that dance floor is plenty big enough for me to turn circles on playing guitar while riding my bicycle no hands. I don't drink hard liquor if I am bicycle guitaring, but at a local brew pub that has outside tables with space enough for me to ride I learned one beer an hour can be tasty and fun. More than that and my music gets sloppy. Much more than that and my riding gets sloppy.
On the bicycle I usually do bluesy rock, folk rock or punk rock improvisation. It can be tricky when circling around a crowd to play some songs like Help! (The Beatles), Dream On (Aerosmith) or Dust in the Wind (Kansas) because these songs have riffs or arpeggios that require precise picking and when on a bicycle sometimes the environment (the surface I'm riding on but even more the movements of people and animals around me) requires my focus more than the music. I can usually play More Than a Feeling (Boston) or Behind Blue Eyes (The Who) all right while circling even in a crowd.
It's also a lot of fun to make up new songs on the spot from what people around me are saying. People who know me are used to this, but it can annoy someone who doesn't know me to suddenly hear what they just said being sung. I take some of their exact words, and then play off them, extend them, sometimes add silliness, or just keep listening and after they say something more I sing it for the next verse.
