Thanks so much for the reply to my request.

I had to take some time off on this project, but it's back on the table.

So, using seven of the leaf batteries sounds like a great idea, and it looks like the AXE controller is accurate, so that would indicate that the system is a 48 volt system and using seven of the 7.6 Volt batteries would work nicely (can you use the charger that is on the bike for those batteries? need to do some foot work there).  If you have a thread on the battery replacement, that would be great!  There are options out there for getting Nissan batteries, but I may just buy a batch and use them for some other projects.

It appears rather difficult to get a hold of the original motor and maybe there is a better option.  I had a friend give me details on the Golden 5 kW motor at 48 Volt.  Just from some drawings on line, it looks like it would fit without modifications.

Any thoughts on the drive motor sprocket sizing?  Since I don't have the original motor I have no idea what size sprocket to consider.  I would rather prefer to move over to belt drive, but it would help to understand that option a bit better. 

I will also look to replace the contactor completely.  Any thoughts on options for different contactors?  I am thinking a slightly higher Amperage than the standard 200.

Any real gottchayas I might be missing here?  I started taking the battery apart and it appears there is a low voltage transformer on the bike to handle the 12 volt accessories, I assume that it's a 48 volt to 12 volt converter, but not sure as there are no marking.

Thanks again for all the support.

Hello,
I am completely new to the electric motorcycle world, but highly enthusiastic.  I just grabbed hold of a 2010 zero that has a dead battery and the motor removed.  All the wiring is still in tact and the bike itself is in great shape!

My son and I decided it was time to do a project together!  This is it.

I am trying to get a handle on just what motor options there are out there for this thing.  Additionally, what controller did this come with and what batter/motor can work with the controller already installed?  Or, do I just need to start over completely and go with a battery/controller/contactor/motor that all work together.  I have not done a search on this forum as of yet, but if someone has a string that I should read, please feel free to cut and past or just direct me accordingly.  My presumption is that there are better motors to choose from now that eight years have passed, but the controller may not handle updated motors and different voltage inputs all that well.

I guess I am starting from scratch.  I'll take any advice.

Thanks in advance!
