Electric set 

 

 

The system uses monitoring of torque, monitoring of speed of the pedal assist system and monitoring of 
real speed of wheels.  
The system uses a dual protection feedback for measuring the speed signal to ensure safety and 
reliabilityof the system. 
It has high starting torque, maximum torque of over 80 Nm, suitable especially for riding uphill. 
It is highly efficient with low power consumption, long range, low noise levels, and smooth operation.
