The Yukon Step-Thru features our 500w (750w peak) rear hub motor, matched with 4” wide Fat Tires which roll confidently over all sorts of challenging terrain. Regardless of the season, the Yukon is ready to face the challenge. Check out the reviews on the product page. Our customers love how this bike is built like a tank, with a matte black metal fenders to keep you clean as your 4” wide Kenda Fat-Tire roars over the gravel and snow beneath you.
