The Ptarmigan Touring Step Through is a well rounded e-bike perfect for commuting or touring. As a 21 - speed bike (3 x 7), the Ptarmigan allows the rider to fine tune their gearing for any situation. The step through frame makes for easy mounting/dismounting, and the 26” x 1.75” tires can handle the Alaskan pavement, gravel, or light trails with efficiency.
