I'm trying to upgrade my S750 to a bit more power and noticed that currie made a 1000W motor. I cant find it anywhere. Anyone know where to get one or have one that would be willing to sell? Thanks.

I had an E-Zip 750 (same machine as yours I bekieve)
The 750 motor is very understressed.
I had very good luck by adding another battery (36 volts) and adding 4 teeth to the motor sprocket.
It went from 15 mph to 25-29 mph. As for reliability, I gave it to my grandson and he hasn't been able to blow it up.
Let me know if you want details

Thanks for the response. the 750w motor I have is rated at 36V and I am overvolting it to 51.8V with lipo batteries with a 50A, 48V controller. You are right its a pretty strong motor and understressed at stock voltage. With the lipo batteries, It accelerates pretty quickly, and runs about 21mph right now with the stock gearing. I'm looking for a bit faster. I know the 1000W motor is about 2" longer and about 1/2" wider than the 750w and it has fins so it should stay cooler. I've been looking everywhere, but I cant find anyone that carries it.

It sounds like you have definately taken care of the battery upgrade.
You probably will need a bigger motor although that is going to take some fabrication skills I'm afraid.
In the meantime you might want to try a taller gear.
TNC Scooters has a 15 tooth (item # 106015)
It fit mine without having to lengthen the chain, although barely.
My stock 11 tooth sprocket was pressed on rather firmly (in addition to the roll pin), so plan on a small puller to get it off.
Either way, let us know how it turns out.

I sent you an email about the motor. I have been running the 750 motor and was working pretty well. I ended up upgrading it to a 1000W unite motor and building a new motor plate out of aluminum. Its a nice upgrade. The 36V unite motor at 52V runs pretty nicely on the bike and doesnt get warm at all geared with a 13T pinion.
