Thanks Rob. It's a 1600 watt 48 volt brushless that's supposed to be 4800 rpm. I use a 50 amp, 130 cell lithium pack. My previous 1000 watt motor fit under the frame after I modified it a little bit but it would occasionally be under water in rain storms so I mounted this one up on top.
The gearing's 11 to 44 which is supposed to be about 37 mph with my tire measuring 10.25. Of course that's in a perfect world.
With both tires a little soft (to help the ride) and a 9 3/4" rear, I hit 31-32 on gps.
With the bigger rear (and both pumped up a little firmer) my friend's motorcycle clocked me at 35, but I might have been a little shy of that. Hard to trust speedometers.
I'm only 150 pounds and it seems to go the same speed down hill as it does on level ground, so I think the gearing's pretty good for this motor and me. I keep the bearings pretty well oiled but they must have a few thousand miles on them by now, and I'm thing about upgrading them. I know higher quality bearings made a big difference on my roller blades in the 90's!
It's pretty much my main way to get around lately and with the fat rear tire, I can just hit the "throttle" and it wheelies a little and gets out in front of all the bicycles and I'm gone.
I'm wearing out the little brake pads though. I buy used bicycle components pretty cheap, so that helps.
