As a real bull presents the 27.5-inch mountain bike Bulls SIX50 EFS 3- and in all respects. The tangy motor chasing the agile basement through the terrain and on the trail. More driving pleasure does not give a pedelec throughout testing. The performance is by no means at the expense of too low a range. Among others with Shimano XT shift full suspension bike is equipped first class.
