Group rides are a lot more fun with music. A soundtrack helps create a festive feel, improves the ride’s safety as it lets drivers know you’re coming, and gets the neighbors to notice –or even join– the ride. There are many good ‘instructables’ on the web that can help you create that special mobile sound system. We link to a few examples below. If you have a favorite design, please let us know!
