Penny: Sounds wild but totally doable – bolt a speaker to the front wheel, add a vibration motor on the handlebars, hook it all up to a tiny microcontroller that syncs with the beat, and you’ll have a moving light show that actually raps back to the music. Need a decent battery though, or you’ll be humming to the tune of the charging cord. Let’s prototype it and see if the bike can keep up with the groove.
