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, ora |. whenever you damn well feel like it.
