I have an ezip 750 running 48v on the stock motor. Haven't clocked the speed yet, but my ezip 500 was doing 33mph with the same setup and a 90 tooth rear sprocket.
The 750 has a much smaller rear sprocket and it feels it does close to 40 mph or over in a straight, with slight less climbing ability. Will clock the speed soon (finished it yesterday)
I had to replace the controller for a cheap chinese controller out of eBay, only 20 bucks shipped and works great. Controller is rated 30 amp 48 v.
The stock controller in my old 500 can take up to 43 volts before it goes into protection. So I run it dead stock at 36v (41v fully charged) using 3 sla batteries in series. It did something close to 25 mph. Newer controllers had something to prevent this. I still have the controller is someone wants it to run 36v.
In the 750 I was able to fit 8 packs of Turnigy 6s 5ah lipo packs, so it has a 48v 20ah battery pack that fits in the stock compartment. It
Should have a range of over 30 miles ( the 500 did 15 miles with half the battery same controller, and doesn't have a free wheel in the rear wheel, my 750 does).
I will use it for commuting to work in Boston, it works great, faster than a car for sure in traffic.
The motors in the ezip 500 and 750 are exactly the same, both rated 24v 28amp 2600 rpm at 24v.
Hope that helps
