We do have some good hills here so should be fun!
This is the rear axle, i basically just chopped off the part of the bike that supports the seat as it was round.

Here is what the wheels will be sitting on, i'm using M8 bolts as they sit snug with the bearings i have from my scooter. A little metal sleeve will added, then a washer and locking nut.

Hopefully should have it all built up today and then i just need some PVC plastic tubing
