The GRINDER EVO was developed on the basis of this type of long-distance racer which is used in the USA for racing long distances on gravel tracks. With its sporty, laid-back look, the strong BOSCH Performance Line CX drive unit and the fully integrated BOSCH PowerTube battery pack, it is a gravel-e-bike that is designed for daily journeys and long trips. With mud guards and saddle back rack it has the right equipment on board for both everyday and leisure use. The athletic character of the all-round racer is further underpinned by the SRAM Apex racing bike group with brake-shift lever and hydraulic disc brakes. The perfect combination of speed and grip on variable terrain is provided by the high-quality Schwalbe G-One tyres. And so a maximum drive unit-power and sporty long-distance comfort were combined to create a versatile speed e-bike for fast rides on and off the street.
