Biking in Summit County is an awesome summer activity. There are hundreds of trails either on or off the ski resort mountains. Mountain bikes are more durable and heavier than traditional bikes and if you do decide to go biking, please make sure you have all the proper equipment such as helmets, gloves, water for hydration, a pump, first-aid kit, repair tools and the necessary knees pads, elbow pads and maybe even armored jackets and shorts as you never know what might happen. The Keystone Resort is awesome for downhill biking with the numerous trails ranging in steepness and there are multiple other trails in Keystone, Dillon, Frisco and beyond. Here are some nearby rental shops that have experienced staff and a wide selection of products to get you on the mountain and good to go.
