Find for a "Welcome to Santa Cruz" painting on Mission st and you will see Epicenter Cycling's Santa Cruz Ca bicycle shop. The staff here is really receptive and all are long time bike enthusiasts. Buy a bike here and get lifetime tune-ups, awesome! For mountain bikers, their Aptos store is located at the entrance of Nisene Marks park which includes a wide mixture of single track and fire road trails. There is also a mountain bike pump track that all ages and skill levels can use to improve riding abilities that is located behind the bicycle store.
