    Kidical Mass is a legal, safe and FUN bike ride for kids, kids at heart, and their families. The first ride was held in April 2008 in Eugene, Oregon and has now spread to over a dozen communities throughout North America and beyond. The rides are meant to be family friendly bike rides through a community. They generally meet at a park and end not too far away at another fun spot (park, ice cream shop, pool, or special event). Each community figures out the type of ride, routes, locations, and events that work best for their area families.

    All types of bikes, trailers, trail-a-bikes, Xtracycles, longtails, bakfiets, Long Johns, tandems, folders, trikes, and whatever rolls are welcome! We celebrate the fact that Kids are Traffic Too and aim for family fun on vehicles that don’t hurt the future! It’s just another excuse to pedal around town with your family.

    Here in Eugene we do the rides on the third Saturday of the month. The rides meander through neighborhood streets and ‘bike boulevards‘ to an ice cream shop, hot chocolate bar, or other fun spot to be determined….

    BRING: A smile, a friend, your bike and another family*.
    *Helmets are heavily encouraged (and legally required for the kids in Oregon and many other states).
