AKM-100SX 36V250W Front 201rpm vs 328rpm

[vfr400]

The 260 rpm one will reach about 19 mph on the road with a charged up battery and the other one will be about 1 mph slower. Obviously, the one with the higher voltage will make 20% more power, so it'll hold on to it's speed better, but by the time you get to 20A, they'll both max out fairly easily, so you'll only see the difference on the hills.

I have a front hub from a Swytch ebike kit that I use with a 48v 20a controller and battery. It is rated for 260RPM's at 36v, but running at 48v makes it a 328rpm motor. That is the sweet spot in my opinion of weight power and speed. I can go 25mph on flats, and 28+ downhill, which is perfect for NYC. This allows me to keep up with the cars in the street and run with the timed lights. Been running this setup for over a year now without an issue.

It's hard to find a rear AKM-100sx with a 260rpm at 36v. The rear 100sx motors all seem to be either 201rpm's or 328rpm's. When boosting to 48v you will either barely go 20mph or will not have enough torque to go up a hill. Make sure to look for a 260RPM @36v rear motor if your planning on powering it with 48v. Or get a straight 328rpm @ 48v motor, but I imagine they are heavier.

As mentioned the 328 is ok as long as one has flat terrain to ride on, if one has hills to contend with it isn't much good unless used in 16"wheels.
