The maximum power output of 500 watts and an efficiency of more than 80 %. The motor is equipped with a torsion sensor that helps to depend on how hard we pedal.

Power is provided by a reliable 500 Wh frame battery that lasts for really long trips. The model is built at 29" for fast trail riding and all-day touring. Just to your left, you will find the SPORT DRIVE control unit, which shows you, for example, the battery level or the current speed. Comfort is taken care of by a suspension fork with 100 mm travel and safe stopping is the job of the powerful Shimano disc brakes. The bike is fitted with full touring equipment such as a rack, mudguards, kickstand, lights, and lock. In terms of additional comfort, you'll appreciate the WTB Nineline 29x2.25" tires with reflective stripe. The ROCK MACHINE Storm INT e90-29 touring can therefore become just your companion for city or countryside trips.
