Thanks Gary and Allan!
For what its worth the spokes are 160mm from elbow to end.
I'm in Australia
I have been contacted regarding spoke purchase.
I don't have disk brake's. The main brake action on the Magic Pie is 'regenerative braking'
On another post someone else said they had loctied /glued spokes in and it fixed there problem, so I planned to go with that idea. Its the sort of thing I would do on my motor bikes for troublesome bolts.
How expensive is expensive for spokes?
Hopefully I will back on the road soon.
