Extreme Ski & Bike started in 1994 in Rancho Cucamonga, California, eventually moving the business to Wisconsin in 1996. Located in the quaint village of Thiensville, we are known as the neighborhood Trek store. Small on the outside, but large on the inside, we carry more floor model bikes than most stores in the entire Milwaukee area. We are a full service ski and bike shop. We are very family friendly, grow with you programs are available, in both ski and bike.We have annual ski and snowboard rentals, as well as, daily or weekly bike rentals. We are very active in the bike racing scene, road and mountain.. We are family owned.
