Giant Electric bike (home NG10)

Giant e-bike. No battery.

This came from an auction and had an incompatible mountain bike front wheel.
I have taken photos of it with a 700c front wheel; however, this is not included, just to help me wheel it about.

I have tested the phases of the rear wheel motor and it is okay.
Front brake was disassembled I have the rest of the bits.
Rear tyre has now been inflated and appears to be staying up.
