The mission of Momentum Bike Clubs is to positively impact the development of young people through mentoring relationships by establishing bike clubs in under-served communities. Momentum Bike Clubs works with youth, ages 11-17, who are open to vigorous exercise and healthy peer and mentor relationships. With the assistance of local community-based partners, we recruit eligible youth and connect them with volunteer adult mentors. The underlying philosophy of Momentum Bike Clubs is anchored in Positive Youth Development, an intentional approach that engages youth within their communities in a manner that is constructive and affirming youths’ assets and strengths. It also promotes positive outcomes for youth by providing opportunities, fostering positive relationships, and offering consistent support to build on their leadership potential.
