The higher the gearing (larger wheel sprocket) the slower the acceleration will be and less torque will be available for hill climbing.
We sell the sprockets, freewheel, and mounting bolts.
The sprocket item numbers are: SPR-2555, SPR-2565S, and SPR-2580
The freewheel item number is: FWM-125
The mounting hardware item number is: HDW-100
All of these parts are available on this page: https://www.electricscooterparts.com/sprockets25chain-wheel.html
After installing these parts the alignment between the new wheel sprocket and the motor sprocket may be offset. Flat washers can be used as shims between the freewheel and sprocket to bring the wheel sprocket into alignment with the motor sprocket.
Thanks. I've also heard about changing the motor gear to something else. I looked on your motor section and you sell the motor with 11 or 15 teeth. I'm not sure what sprocket my motor has. I found someone on youtube that is using a 13t on the motor. Would that be something you'd suggestion. And if so, would the part SPR-2513P be correct?
As you can see the top speed cannot be changed very much by increasing the motor sprocket size, however, if you are only looking for a one or two MPH increase in top speed then they will work great for that.

Are these parts direct swap or are there other modifications that I would need to do? Also, if you did a 13 tooth motor sprocket with a 65 tooth wheel sprocket, could it go even faster?
I was given this scooter from a friend for free as they are moving and don't have room for it. It's got a dead battery and its been sitting for a long time. I know absolutely nothing about these things.
I pulled the battery pack out and it's 3 12V 10AH lead acid batteries in series for 36v. I found some cheap lithium 18650 10s2p 36v 4.5ah battery packs on ebay and replaced the 3 lead acid with 6 of those packs for 27ah of lithium.
I got it running and it works, but I find it to be a little slow (15mph) and I'm looking for upgrades to make it go faster. I found a few of forum threads talking about upgrading the ezip 1000 to 48v (https://support.electricscooterparts.com/support/discussions/topics/1000085321), but couldn't find any that specifically talk about the izip. I'm honestly not sure what the difference is, but I'm looking for mods to make this go faster. Is there a way to go faster with the stock 36v motor/controller/battery config or is 48V the only way to go? I found a thread talking about going from 36v to 48v with the following:
I understand if I go 48V, I'd have to break down these battery packs to rewire for 48V, which I'm okay with doing, but I need to know what parts I would need to support a new motor and controller. Would it just be those two parts? I'm really new to this stuff, so please bear with me if I sound like I don't know what I'm talking about, because I don't ;)
