TRX 1.3



The BESV TRX 1.3 is our hardtail e-MTB equipped with a 630Wh battery and the Shimano EP-800 motor with 85Nm of torque. The RockShox fork has 120mm of suspension travel and provides control and stability. Of course, looks are important too, which is why we chose the matte Kaki Sand color combined with Maxxis Ardent Skinwall tires for the Step Over variant and Gentle Green for the Low Step variant.

  • 630Wh Battery
  • Deore 11 Speed
