Shift your thinking, shift your lifestyle and shift into fun with Trek's Shift 4. The Shift is the answer to people who think that riding may not be an option for them. A low, long design inspires confidence and gives you stability and control. The strong aluminum frame and durable components allow for riders up to 350 pounds. A comfortable bike is a ridden bike, so your Shift is equipped with an adjustable stem, upright bars, and a plush, supportive seat to allow the perfect position. If that wasn't enough, you have a suspension fork up front to smooth out any bumps in your path. Plus, this great bike sports 24 gears to top hills with ease and powerful linear-pull brakes for the ride back down. Heavy-duty wheels and puncture-resistant tires add peace of mind. Welcome back to riding, welcome back to the outdoors.
