Hi E-bikers, I recently purchased a second-hand Currie 2015 IZip Zuma E3 (48V). The previous owner let it sit for several years. I knew it had a few issues (including a flat-lined battery) but it was a beautiful bike and wanted to resurrect it to its former glory and save it from the dumpster it was headed to. Unfortunately, it looks like the specific bike from this series was discontinued and this has only complicated my endeavor.
Upon getting the bike I was able to quickly disassemble the battery pack and replace/spot-weld in 2500mah LG 18650s. Luckily the BMS still worked bringing the bike back to electrically running condition. Now I can I-zip around electrically but the chain drive is still giving me trouble. The smaller battery in this bike really needs the pedal assist to make it really useful with such a small battery.
The pedals on the bike slip when peddling and after some disassembly I have concluded the freehub body has a problem preventing the teeth from engaging (or worse the teeth on receiver are gone). I tried cleaning it and reassembling it to no avail. Is it possible to get a part number of this freehub body? I had a hunch that the motor is a Bafang 500W CST but I couldn't be sure (see pics). Even knowing this, I couldn't seem to find replacement parts for the freehub. I attached several pictures to help the effort. Any help would be much appreciated. I sent an email to Currie and received no response, but as a secondary customer, I don't blame them.

After the battery was rebuilt the bike could get around 8 miles on totally flat Florida ground with just twist throttle before the display would shut off. I assumed was a low voltage shut off. Is this in line with what is expected stock? Does this approximate range make sense?
Again to recap my questions are:
Is it possible to replace the freehub body on the motor entirely? What about the teeth on the motor side?
Is the normal operation of the controller display to shut-down upon low voltage cutoff (LVC) on Currie bikes?
Is the motor on this bike a Bafang CST 500W? (See pics)... If so, I may be able to get some parts somewhere.
