Grit, determination, ambition. It’s what makes America great and it’s what makes the Grinder EVO the bike it is. It’s fast, assisting up to 28mph (Class 3) with gravel bike geometry and drop bars. It’s driven by the Bosch Performance Speed motor and draws its power from— you guessed it— the Bosch 500Wh Powertube beautifully and inconspicuously grafted into the frame. You will get where you need to go when you you need to get there, or…. whenever you damn well feel like it.
