You can do a torque mod to your controller to increase the AMPs going to your motor. This will increase your E-Bikes acceleration and hill climbing power. But it will not increase your speed. To increase your speed you will have to add more batteries in series to increase the voltage. Then replace your controller and DC to DC controller to models that will handle the higher voltage. Then buy a charger to charge at the higher voltage. This can get expensive for just a increase in speed of 5-15kph only.
Thanks,
