Why e-Race system adds 1.5kg only to the weight of my bike?

E-Race System includes extralight components. The total weight of the system with the small battery and the 250W08 motor is 3,1kg. After the system is mounted it adds 2,7kg only as the rear hub of your bike gets removed and substituted with the motor. The battery is not integrated and can be easily taken away, so if you want to pedal yourself you simply leave the battery at home. In this case your bike has 1,5kg only to its original weight.
