The perfect option for the active parent. The swiveling front wheel allows you to maneuver in tight corners or through crowds but the option to lock the wheel still allows you to go out and run that 5K with the little ones. The 12″ front & 16″ rear pneumatic air tires and alloy rims provide performance and style while the aluminum frame makes this a lightweight stroller. Parent tray and dual fin grip cup holders adds convenience. Dual trigger folding mechanism offers uncompromised safety, rubberized grip is comfortable and slip resistant. The canopy mounted speakers accepts most MP3 players.
