The neighborhood Trek store
Extreme Ski & Bike started in 1994 in Rancho Cucamonga, California, and moved to Wisconsin in 1996. The family-owned shop calls itself small on the outside and large on the inside, and says it carries more floor model bikes than most stores in the Milwaukee area. It is active in local road and mountain bike racing.
The shop sells Trek and Electra bikes, including electric, mountain, road, commuter, comfort, cruiser, hybrid and kids models, plus Burley trailers, car racks, parts and apparel. Grow-with-you programs are available for kids in both skiing and biking.
