In case you're wondering, electric bike controllers send the signal to the motor hub in various voltages.  We carry both analog and digital controllers.  Following are some specifications for these two types.

Controller Range :

1. Voltage range : 24V 36V 48V and 72V
2. Current ( Amps ) : 12A 15A 20A 35A 40A and 48A

* Mosfet irf3205 ( 24V ~ 36V ) or irf4710 ( 48V )

　
+ Increase Voltage ( V ) => Will increase the motor speed
+ Increase Current ( A ) => Will  increase the motor torque
* The high current controller ( Currency at 35A ~ 48A design for high loading )


+ 12A and 15A design for lithium battery
+ 20A design for NiMH or SLA Battery
+ Function : Immediate and Pedal First Start available
