We have a good amount of experience with the Falco kits and I think the 1,500 Watt motor might be a bit of overkill. You might find a 750 or 500w motor with a 48V battery to be more suiting. Keep in mind these motors are meant to be a pedal assist motor, although these higher watt version can operate without much need for pedaling. My big concern would be the battery size you would need to support a motor like that and get a decent range. I saw you mention in another post you are looking for speed, I can get to 35mph with a 48v battery while pedaling hard and I can maintain a speed of 25mph, that's with a 44t chainring, I'm working on implementing a Metropolis Patterson drive to try to pedal into 45mph, that's my goal on a 500w motor. I think I might break a record. If you need some insight on your build let us know.
Court, running 48 volts through this motor is night and day from the 36v version. Much more power, it's still not super torquey, but it can give you some serious speed, they can also be custom configured if you need more torque, we're building up a 750 watt wheel chair attachment currently with 90Nm of torque.
