Our freewheel item # FWM-205 will thread onto the eZip 750 rear rim. FWM-205 has an F5 sprocket mounting pattern so a sprocket can be custom ordered with an F5 mounting pattern to work with it. FWM-205 is available on this page:
When ordering a custom-made sprocket from us the F5 mounting pattern can be selected on the order form.
That sounds like a great place to start from. If the motor is not even getting warm then it is definitely a candidate for a larger controller or overvolting. Please let us know how it goes.
We just added the SPD-241000 24 Volt 1000 Watt controller to the site a few months ago so I have not had a chance to try one out yet, and I have not received any feedback about them from our customers yet. I have taken one apart to see what is inside and noticed that they are loaded with a lot of large FET power transistors. We have sold quite a few of them so far and nobody has complained about them being too slow so I imagine that they should deliver a fast acceleration curve and top speed.
Can I use a 12v 18ah battery for an ezip 750 scooter? will it fit?
The eZip 750 electric scooter is a 24 Volt scooter so a single 12V 18Ah battery will not provide enough Voltage for it, however, a battery pack made from two 12V 18Ah batteries will work with it. Two 12V 18Ah batteries are too large to fit in the battery box that the original 12V 12Ah batteries occupy.
I have an older ezip 750 24 volt. I am interested in more amperage or sprocket change that would help with hill climbing. Don't really care how fast it goes.
Thanks in advance!
